6. BRIEF RESUME OF THE INTENDED WORK.
6.1 Introduction.
“Every human being is the author of his own health or disease.”
Buddha.
Wellness is a balanced channeling of energy—energy received from the environment,
transformed within you, and returned to affect the world around you1.The environment plays a
major role in deciding the wellness and illness. Now we are in the technical world where we depend
on the technology for our daily living. Technology and society or technology and culture refer to
cyclical co-dependence, co-influence, co-production of technology and society upon the other
(technology upon culture, and vice-versa). Technology provides an understanding, and an
appreciation for the world around us. Some technologies are designed specifically with the
environment in mind, but most are designed first for economic or ergonomic effects. Historically,
the value of a clean environment and more efficient productive processes has been the result of an
increase in the wealth of society, because once people are able to provide for their basic needs, they
are able to focus on less-tangible goods such as clean air and water. There raises the question
whether technology is boon or bane?2
The effects of technology on the environment are both obvious and subtle. The more obvious
effects include the depletion of nonrenewable natural resources (such as petroleum, coal, ores), and
the added pollution of air, water, and land. The more subtle effects include debates over long-term
effects (e.g., global warming, deforestation, natural habitat destruction, coastal wetland loss.)2.
Most modern technological processes produce unwanted byproducts in addition to the
desired products, which is known as industrial waste and pollution. While most material waste is
re-used in the industrial process, many forms are released into the environment, with negative
environmental side effects, such as pollution and lack of sustainability. Each wave of technology
creates a set of waste previously unknown by humans: toxic waste, radioactive waste, electronic
waste2.
One of the main problems is the lack of an effective way to remove these pollutants on a
large scale expediently. But no such mechanism exists for the removal of technological wastes2. One
of such pollutant is plastics which is mandatory in our daily life resulting in increase in the number
of plastic more volumes of waste materials, excessive energy consumption correlatively with
increase in toxic pollution both to the environment and to the human2. Plastic has become an
environmental problem of global scale. As plastic is non-biodegradable, toxic and not recyclable in
the true sense of the word, the need for an international coalition against plastic waste is paramount3.
While plastics are yet to be considered a significant disposal problem in much of the first
world (largely because these materials are land filled--out of sight, out of mind), organizations in the
global south have demonstrated considerable concern in regards to the detrimental effects of plastic
products, notably the terminal waste generated by their disposal. Direct disposal (littering or
dumping) and incineration (burning) of these wastes is a common practice in the global south3. This
is harmful to the health of people and the environment. Because dumping in rivers, streams and even
urban drainage systems pollutes water courses and causes flooding. When these waters are
unsanitary, they carry disease into the household. The burning of plastics encourages airborne
pollution, the majority of which is extremely toxic and can cause a host of health problems (cancer,
asthma, etc.). Although land filling and recycling programs "vanish" the waste problem, each has
considerably negative consequences: landfills leak and often contaminate the ground water with
toxic liquids and residues3. The recycling of plastic is often accomplished by exporting waste
materials to Asian countries where recycling facilities are often likened to "sweatshops" where by
laborers prepaid little for dangerous work. The increased push for unfettered trade and neo-liberal
policy has scudded in intensifying these problems3.
Acute exposure of humans to high levels of PVC’s components via inhalation has resulted in
CNS effects such as dizziness, drowsiness, headaches, and giddiness. These effects can occur within
5 minutes if one is exposed to about 10,000 ppm of vinyl chloride. It is reported to be slightly
irritating to the eyes and respiratory tract in humans. Acute exposure to extremely high levels has
caused loss of consciousness, lung and kidney irritation, and inhibition of blood clotting in humans.
It has shown to cause cardiac arrhythmias in animals. Although there is a low occurrence of this in
exposures to home products containing PVC, it can occur if there is a home fire. The burning of
PVC products results in the release of dioxins. The hydrochloric acid formed when PVC is burned,
can lead to life-threatening lung damage4.
Using plastic bottles poses several potential hazards. The primary danger stems from a
chemical called Bisphenol A or BPA, which the U.S. Food and Drug Administration or FDA
acknowledges as possibly dangerous. Bisphenol A is an endocrine disruptor, which can mimic the
body's own hormones and may lead to negative health effect5.Styrene (ethenylbenzene) is a
monomer that is incorporated into major polymers and copolymers. The major uses are in plastics,
paints, coatings, synthetic rubbers, and polyesters. Styrene is, however, also used in packaging
(e.g., styrene-containing foams), construction (e.g., plastic pipes, insulation for electrical uses,
fittings, tanks), automotive industry (e.g., tires, reinforced plastics), and household goods (e.g.,
molded furniture, carpet backing). In addition, styrene is used as co-reactant and solvent in
reinforced plastic fabrications, including boats, tanks, pipes and automobile body parts. The main
routes of occupational exposure are inhalation and dermal6.
Harmful Packaging, yet everyday millions of Indians are being slowly poisoned by eating
food packed and served in non-food grade materials. And there’s worse news. Foods that are highly
acidic (pickles) or which contain alcohol or fats (wine, cheese, butter, oil) need a different quality of
food-grade plastic because plasticizers leach more easily into these foods7.
6.2. Need for study
The plastics industry in India is considered a Sunrise Industry and has been exhibiting a
consistent export growth rate in the past8. Plastic bags are an environmental disaster; they are
unsightly, they decimate wildlife, are filling the oceans and are made out of oil so help cause global
warming. The per capita consumption of plastic in the country stood at 6 kg now and is expected to
go up to 12 kg by 2011, by 2012; India is also projected to be the third largest consumer market for
plastic goods with a consumption of 12.5 million tons per annum, behind US and China9.
By the tremendous increase in consumers market creating safety problems during
production, many chemical additives that give plastic products desirable performance properties also
have negative environmental and human health effects. These effects include10

endometriosis, and immune system
impairment.
People are exposed to these chemicals not only during manufacturing, but also by using
plastic packages, because some chemicals migrate from the plastic packaging to the foods they
contain. Examples of plastics contaminating food have been reported with most plastic types,
including Styrene from polystyrene, plasticizers from PVC, antioxidants from polyethylene, and
Acetaldehyde from PET12.Among the factors controlling migration are the chemical structure of the
migrants and the nature of the packaged food. In studies cited in Food Additives and Contaminants,
LDPE, HDPE, and polypropylene bottles released measurable levels of BHT, Chemosorb 81,
Irganox PS 800, Irganix 1076, and Irganox 1010 into their contents of vegetable oil and ethanol.
Evidence was also found that acetaldehyde migrated out of PET and into water10.
Polyvinyl chloride (PVC) is used to make a variety of plastic products including pipes, wire
and cable coatings, and packaging materials. Vinyl chloride can also be produced as a byproduct or
when chlorinated solvents such as TCE& PCE chemically break down. And it will transfer to the
body by breathing (inhalation) vinyl chloride that has leaked from plastics industries, hazardous
waste sites, and landfills, vinyl chloride in contaminated workplace air or having skin or eye contact,
by tobacco smoke from cigarettes or cigars, as well as by drinking (ingesting) water from
contaminated wells11. Phthalates — a class of chemicals used to soften polyvinyl chloride plastics,
found in products ranging from shower curtains to cosmetics to intravenous-fluid bags — have been
shown to disrupt hormones in animals and have been linked to reduced sperm counts and other
marks of feminization in male rodents9.
Plastic drinking bottles contain many chemicals, some of which interfere with hormones in
the body. These chemicals include Bisphenol-A, or BPA, and phthalates, among others. Chemicals
in the plastic can leach into bottled water, especially when exposed to heat or when the bottle is
old11. BPA does its job well, and today some 6 billion lb. (2.7 billion kg) of the chemical are
produced globally each year. The problem is, BPA is also a synthetic estrogen, and plastics with
BPA can break down, especially when they're washed, heated or stressed, allowing the chemical to
leach into food and water and then enter the human body. That happens to nearly all of us; the CDC
has found BPA in the urine of 93% of surveyed Americans over the age of 6. If you don't have BPA
in your body, you're not living in the modern world. More recently, she published a study showing
that the offspring of mice exposed to BPA while pregnant can end up with corrupted eggs, a
situation that leads to trouble for their offspring. "That's a powerful effect". "You disrupt three
generations with one exposure12.
A 2007 review has concluded that BPA, like other xenoestrogens, should be considered as a
player within the nervous system that can regulate or alter its functions through multiple pathways.
A 2007 review has concluded that low doses of BPA during development have persistent effects on
brain structure, function and behavior in rats and mice14. A 2008 review has concluded that obesity
may be increased as a function of BPA exposure. A 2009 review of available studies has concluded
that "perinatal BPA exposure acts to exert persistent effects on body weight and adiposity12.
A 2008 review has concluded that neonatal exposure to Bisphenol-A (BPA) can affect
sexually dimorphic brain morphology and neuronal adult phenotypes in mice. A 2008 review has
concluded that BPA altered long-term potentiating in the hippocampus and even nanomolar dosage
could induce significant effects on memory processes. A 2009 review raised concerns about BPA
effect on anteroventral periventricular nucleus12.
Consumers have been warned about using warm water in some Polycarbonate bottles
because of potential leaching of harmful chemicals into the water. One study concluded that water
inside cloudy or scratched bottles is more vulnerable to contamination from phthalates or
Bisphenol-A (BPA).Phthalates are easily released into the environment because there is no covalent
bond between the phthalates and plastics in which they are mixed. As plastics age and break down,
the release of phthalates accelerates. Phthalates in the environment are subject to biodegradation,
photo degradation, and anaerobic degradation; therefore, in general, they do not persist in the
outdoor environment10.
People are commonly exposed to phthalates, and most Americans tested by the Centers for
Disease Control and Prevention have metabolites of multiple phthalates in their urine. Because
phthalate plasticizers are not chemically bound to PVC, they can easily leach and evaporate into
food or the atmosphere. Phthalate exposure can be through direct use or by indirect means through
leaching and general environmental contamination. Diet is believed to be the main source of DEHP
and other phthalates in the general population. Fatty foods such as milk, butter, and meats are a
major source. Low-molecular-weight phthalates such as DEP, DBP, BBzP, may be dermally
absorbed. Inhalational exposure is also significant with the more volatile phthalates. And dioxins,
phthalates and benzene which are all present in plastic are also stored in body organs if consumed
over a long period of time. They can cause cancer of the gastro-intestinal, renal, neurological
organs10.
Based on a literature review, non-occupational exposure to styrene was estimated to be 18.2–
55.2 µg/person/day, or 6.7–20.2 mg/person/year, mainly from inhalation and food intake via release
of styrene from packaging material. Tobacco smoking is another important source of styrene
exposure, with styrene exposure from 20cigarettes/day being equivalent to that from all other non-
occupational sources combined. And also the inhalation studies provided evidence of an increased
incidence of pulmonary adenoma11.The use of modern disposable, plastic lined nappies (diapers)
could be an important factor in the increasing incidence of testicular cancer in adult age. Parental
occupational exposure to hydrocarbons and risk of acute lymphocytic leukemia in offspring12.
Plastic fact in the 2007: World consumption of plastic is 100 million tons, but in the 1950s it
was just 3 million tons. 1 ton of plastic represents around 20,000 two-liter bottles of water or
120,000 carrier bags. In 2004 global consumption of bottled water alone was 154 billion liters. More
than 1 million birds and 100,000 marine mammals perish each year by either eating plastic waste or
becoming trapped in it. Plastic could take 500-1,000 years to break down. Plastic waste in India is
about 4.5 million tons a year. In future, there is already a strong global movement to ban plastic as it
can cause damage, not just to the environment but also human beings13. Hence the impact of Plastic
usage over health is very massive, the researcher is motivated to investigate and intend to create
awareness on the ill effects of plastics on health in the daily life among the students since they are
being the catalyst to mediate the information to the remaining public.
6.3 Review of literature Literature review refers to the activities involved in identified and searching for information
on a topic and developing an understanding of the knowledge.
The purpose of the review was to obtain information about ill effects of plastic usage in daily
life.
A study was conducted to find heavy metals contamination in surface and ground water
supply of urbanity. The final water supply of four treatment plants and lightly tube wells at Delhi
surveyed for cadmin chromium, copper iron, lead, manganese, nickel, selenium and zinc. On this
most of them are plasticizers. The sample stored at room temperature and inductively. Coupled
plasma atomic emission spectrometer (ICP-AES) was used for analysis. Result showed high levels
of lead, manganese, cadmium, copper and iron compared to the Indian standard specification of
5mgL-1. Thus, the researcher concluded that, the chemical toxicity to the water which causes ill
effects to the human health14.
Hazards wastes are products that could pose shorter long term threats to health or the
environment if they are not disposed properly. The disposal of hazards waste can be very dangerous.
Hazardous disposal sites have become a serious environment problem in the country. In a period of
ten years the hooker chemical ad plastic corporation dumped 22,000 tons of toxic waste in steel
drum in to an old canal. They covered the canal with top soil and the property was then turned over
to the Niagra falls public school district. In 1976 resident became concerned. They began to notice
odd smell. The steel drums were leaking toxic waste in the sewers, lawn and even basement of some
houses. Due to the actions of concerned citizen, the state performed many health studies on the area
and by 1978 the federal government declared lore canal a disaster area14.
A nested case-referent study was conducted in Italy. The aim of the study was conducted to
determine whether PVC and/or vinyl chloride monomer (VCM) is the associated risk factor(s), in
order to estimate lung cancer risk. The methods of the literature includes, 38 cases of histological
verified lung cancer and 224 control subjects without a history of cancer were selected from an
Italian cohort of 1658 vinyl chloride workers. Information sources included clinical records
(diagnosis, smoking habits) and plant records (occupational history). The risk of lung cancer was
estimated by odds ratios (OR) with 95% confidence intervals (CI), calculated using logistic
regression models. The result shows that in PVC baggers exposed to high levels of respirable PVC
particles in the workplace, the lung cancer OR increases by 20% for each extra year of work (OR =
1.2003; 95% CI 1.0772 to 1.3469; p = 0.0010), when the influence of age and smoking habits is
controlled. By this result, researcher concluded that in the VCM/PVC industry, an increased risk of
lung cancer associated with exposure to PVC dust15.
A cross sectional study was conducted in Shanghai Jiao. On Urinary Bisphenol A (BPA)
Concentration Associates with Obesity and Insulin Resistance. The researcher used the
Questionnaire, clinical and biochemical measurements to determine urinary BPA concentration.
According to this study analysis of the literature includes, the participants in the highest quartile of
BPA had the highest prevalence of generalized obesity [odds ratio (OR) = 1.50; 95% confidence
interval (CI) = 1.15-1.97], abdominal obesity (OR = 1.28; 95% CI = 1.03-1.60), and insulin
resistance (OR = 1.37; 95% CI = 1.06-1.77). In participants with BMI under 24 kg/m(2), compared
with the lowest quartile, the highest quartile of BPA increased the prevalence of insulin resistance
by 94% (OR = 1.94; 95% CI = 1.20-3.14), but this association was not observed in those with BMI
of 24 kg/m(2) or higher. This study concluded that BPA was positively associated with generalized
obesity, abdominal obesity, and insulin resistance in middle-aged and elderly Chinese adults16.
A study was conducted on poly chlorinated Bisphenol-A,(PCBs) in the compost amended
soil of a landfill site. The purpose of the researcher was to determine if any of the mixture of PCBs,
aroclor 1254 and aroclor 1260 are retained in the compost amended soil, despite atmospheric loses
possible due to the peak summer (100-1170 F). The method was standardized by taking 10mg of
ground soil sample in duplicate and spiked separately with known concentration of aroclor 1254
solution in n-hexane. The maximum total PCBs concentrations on dry wet basis were found as 1.2
ug/g. The distribution of PCBs levels suggested an airborne mode of transport from the source. This
study concluded that, these compounds have adverse effects on the organism by having deposited at
the top of food web including human being17.
A cohort analysis study was conducted in Geneva, Italy, On Reanalysis of updated mortality
among vinyl and polyvinyl chloride workers: Confirmation of historical evidence and new findings.
The study includes, the Mortality of 1658 male workers was analyzed by Poisson regression.
Relative risks (RRs) and 95% confidence intervals (CIs) for blue collar workers and their specific
subgroups of PVC baggers, PVC compound, autoclave and other blue collar workers were
calculated using technicians and clerks as an internal reference group. The follow-up covered the
period 1972-1999. The analysis of the literature includes the, significantly increased mortality rates
were observed for all causes of death among the whole blue collar workforce (RR = 1.55; 95% CI =
1.03-2.35; 229 deaths), PVC baggers (1.72; 95% CI = 1.04-2.83; 49 deaths) and PVC compound
workers (1.71; 95% CI = 1.09-2.67; 72 deaths). Liver cancer, including angiosarcoma, was
increased among autoclave workers (9.57; 95% CI = 3.71-24.68; 7 deaths) and cardiovascular
diseases among PVC baggers (2.25; 95% CI = 1.08-4.70; 12 deaths). Hemolymphopoietic system
tumors, leukemia’s and lymphomas prevalently, were found only among exposed workers, with 4, 4
and 6 deaths observed among PVC baggers, PVC compound and other blue collar workers,
respectively. An excess of lung cancer was found among PVC baggers. This study concluded that,
all causes of death and all tumors were increased among all blue collar workers18.
A cohort case control study was conducted in, Taiwan on Interaction of vinyl chloride
monomer exposure and hepatitis B viral infection on liver cancer. The aim of the study was to
determine the role of HBV on the development of liver cancer in the VCM-exposed workers. A total
of 18 patients with liver cancer, and 68 control subjects matched for age and specific plant of
employment were selected. Detailed history of the participants that included alcohol consumption
status, cigarette use, occupation, and family history of chronic liver disease were obtained using an
interviewer-administered questionnaire. When the HBV surface antigen (HBsAg)-negative subjects
without history of tank-cleaning were used as the reference, the HBsAg-negative subjects with
history of tank-cleaning demonstrated a 4.0-fold greater risk of liver cancer (95% confidence
interval: 95% CI = 0.2-69.1). The HBsAg carriers without history of tank-cleaning revealed a 25.7-
fold greater risk of liver cancer (95% CI = 2.9-229.4). Whereas the HBsAg carriers with history of
tank-cleaning revealed the greatest risk (matched odds ratio (ORm) 396.0, 95% CI = 22.6 -infinity)
of developing liver cancer among subjects with different VCM-exposure status and HBsAg status
categories. Further analysis showed the interaction term was significant (P < .01). This Study
concluded that, an interaction between occupational VCM exposure and HBV infection for the
development of liver cancer19.
A experimental study was conducted in U.S.A. on Vinyl chloride exposure and human
chromosome aberrations. The researcher used the Examination of l lymphocyte cultures from 11
vinyl chloride polymerization workers and 10 controls revealed a significantly higher incidence of
aberrations in the exposed population. Most of the excess damage was of the “unstable” variety and
involved the grossest kinds of changes such as fragments or rearrangements. When these complex
changes were regarded as the product of two breaks, the incidence of all breaking events was also
significantly increased in the workers. Then the researcher concluded that the presence of
chromosome damage in vinyl chloride exposed workers20.
A study was conducted in United Kingdom. The study was to; review the evidence for the
role of exposure to phthalates from PVC products in the development of asthma and allergies. And
the researcher collected review on 27 human and 14 laboratory toxicology studies. Two mouse
inhalation experiments indicated that mono-2-ethylhexyl phthalate (MEHP) has the ability to
modulate the immune response to exposure to a co allergen. The data suggested a no observed effect
level of 30 micro MEHP/m3, calculated to be below the estimated level of human exposure in
common environments. Case reports and series (n = 9) identified and verified cases of asthma that
were very likely caused by fumes emitted from PVC film. Epidemiologic studies in adults (n = 10),
mostly small studies in occupational settings, showed associations between heated PVC fumes and
asthma and respiratory symptoms; studies in children (n = 5) showed an association between PVC
surface materials in the home and the risk of asthma [fixed-effects model: summary odds ratio (OR),
1.55; 95% confidence interval (CI), 1.18-2.05; four studies] and allergies (OR, 1.32; 95% CI, 1.09-
1.60; three studies). This study concluded that, High levels of phthalates from PVC products can
modulate the murine immune response to a co allergen. Heated PVC fumes possibly contribute to
development of asthma in adults21.
A comparative study of global migration levels of recycled vs virgin poly ethylene for
packing and storage of milk was done by using a sample of vigin and recycled blended polyethylene
films. A piece of LDEP(low density polyethylene) was brought into contact with the stimulating
solvent under the specified time and temperature. At the end of prescribed duration, the contact
liquid evaporated and the redue was weighed for a constant weight. Analysis showed increase value
of global migration with increase percentage of recycled granules and percentage and type of
activity in film at very temperature and time combination with all extraction method. The
extractability (leaching from the LDPE) was determined by contracting the polyethylene sample
with either the food material or a range of oily, alcoholic and aqueous extractants which stimulate
various food14.
A study was conducted to evaluate the effectiveness of planned teaching program to the high school students on hazards of plastic use in a selected school of
Mangalore. Samples were collected from 100 English medium high school students; the data were collected by structured teaching knowledge questionnaire. The data were
analyzed by the descriptive and inferential statistics by the (x2 =22.81) when compared with the mean pre test (x1= 14.61) knowledge score. The compound “t” value (t99=
28.7 p<0.05) showed significance in the effectiveness of planned teaching program14.
