KETAHANAN LINGKUNGAN:
Environmental Hazards & Human
Health
Apakah bahaya lingkungan ?
'Environmental hazard' is a generic term for any situation or state of events which poses a
threat to the surrounding environment.
This term incorporates topics like pollution and natural hazards
such as storms and earthquakes.

BAHAYA DAN RISIKO
BAHAYA = Hazard:Is “a factor or exposure that may adversely
affect health” it is a qualitative term expressing the potential of an
environmental agent to harm the health of certain individuals if the exposure level is
high enough and/or if other conditions apply.
RisikoIs “the probability that an event will occur, the
probability of unfavorable outcome e.g that an individual will become ill or die within a
stated period of time or age. It is the quantitative probability that a health effect
will occur after an individual has been exposed to a specified amount of a hazard.

KONTAMINASI
Contamination -- Introduction into water, air, and soil of
microorganisms, chemicals, toxic substances, wastes, or wastewater in
a concentration that makes the medium unfit for its next intended
use.
Also applies to surfaces of objects, buildings, and various household and
agricultural use products.

PENCEMARANPollution is the introduction of
contaminants into an environment that causes instability, disorder, harm or
discomfort to the ecosystem i.e. physical systems or living organisms.
Pollution can take the form of chemical substances, or energy such as noise,
heat, or light energy.
Pollutants, the elements of pollution, can be foreign substances or energies, or
naturally occurring; when naturally occurring, they are considered
contaminants when they exceed natural levels.
Pollution is often classed as point source or nonpoint source pollution.

POLUTAN = PENCEMAR• A pollutant is a waste material that pollutes
air, water or soil. • Three factors determine the severity of a
pollutant: – Sifat kimianya, – Konsentrasinya– Persistensinya.

"Pollution" is generally used when you're talking about something big, like a
whole environment, or an entire river, or something else really large.
"Contamination" can refer to very small quantities of something - contaminated food, medicine, drinking water supply; it
can also mean a very small amount of foreign or harmful material, such as bacterial contamination, or a toxin,
especially when it's not readily visible or noticeable.
For instance, a surgical suite could be contaminated simply because someone
walks into it when they're not sterile, and it would be completely invisible.

POLUTAN & KONTAMINASI
ANY external factor that negatively affects your health can be
considered an environmental health “hazard." Common environmental health hazards include indoor and
outdoor air pollution, and contaminated food and water. Less commonly discussed environmental health hazards
include lack of sidewalks, crime, insufficient physical activity, poor nutrition, social isolation, noise,
stress, and the lack of aesthetically pleasing living environments.

Routes of intestinal exposure to air pollutants. Urban and industrial air pollutants can contaminate food and water, which are then ingested by humans or indirectly
enter the human food chain through consumption of contaminated animals.
Pollutants are also inhaled and then either absorbed systemically and delivered through the blood stream
to the gut or cleared by airway cilia and then ingested.

BAHAYA PSIKOSOSIALCommon Signs of Anxiety
Anxiety itself could also be a result of a deeper physiological or psychological cause. That is why the
possible manifestations that are associated with anxiety are numerous and can be classified into the specific areas
of the body affected. Anxiety is often difficult to identify in a person. Extreme cases present with severe symptoms.
This makes stress or anxiety exercises and treatments an essential for anyone going through
anxiety attacks.

– Stress is a human response to stressors
– Stress is a specific event or situation that causes a mental or psychological reaction.
– Stress is a process resulting from the interaction between humans and the environment.
– Stress process consists of 2 stages:
• Deciding whether or not an event (stressor) poses a hazard
• Appraising the possibilities of dealing with the situation.

Climate change and health Climate change has a range of complex interlinkages with health. These include direct impacts, such as temperature- related illness and death; the health impacts of extreme weather events; the effect of air pollution in the
form of spores and moulds.
BAHAYA KESEHATAN YANG PENTING? Do We Face?
The effects of environmental exposures on health depend on the social settings in which the exposures occur and on individual behaviours.
Behavioural risk factors are sometimes closely related to physical risk factors (e.g. hygiene is related to sanitation) and modify the health impacts
of the physical risk factors. Indeed, the specific contributions of related behavioural and physical risk factors sometimes cannot easily be separated,
as for example in the risk factor "water, sanitation and hygiene".

PENTINGNYA KESEHATAN AIR
• There are 4 billion cases of diarrhea worldwide each year and 2.2 million avoidable deaths-that's a death every 14 seconds.
• Most diarrheal deaths occur in the Majority World and just being able to wash one's hands with soap and water can reduce diarrhea by 35%.
• Insect-related diseases Malaria, is the biggest killer, causing 1-2 million deaths a year. At any given time 100 million people suffer from the disease.
• Parasites Intestinal worms infect about 10% of the majority world population. About 200 million people are affected by schistosomiasis (bilharzia), with 200,000 dying each year.
• After a peak in the late 1980s, guinea-worm infections have been declining as water sources are better monitored.
Sumber: Environmental Health Hazard . Atallah Z. Rabi …. Diunduh dari: www.sawa2006.com/.../22%20-...... 15/12/2012
• Every day, diarrheal diseases cause some 6,000 deaths, mostly among children under five: in 2001, 1.96 million people died from infectious diarrheas; 1.3 million were children under five.
• Diarrheal diseases have killed more children in the past ten years than all the people lost to armed conflict since World War II.
• Between 1,085,000 and 2,187,000 deaths due to diarrheal diseases can be attributed to the 'water, sanitation and hygiene' risk factor, 90% of them among children under five.
• With simple hygiene measures such as washing hands after using the toilet or before preparing food, most of these deaths are preventable.

The World Health Organization (WHO) and the Food and Agriculture Organization of the United Nations (FAO) are in the forefront of the development of risk-based approaches for the
management of public health hazards in food. The approach used is called risk analysis, and is made up of
three components: Risk assessment; Risk management; Risk communication

Biomagnification, also known as
bioamplification or biological magnification,
is the increase in concentration of a
substance that occurs in a food chain as a consequence of:
1.Persistence (can't be broken down by environmental processes)2.Food chain energetics3.Low (or nonexistent) rate of internal degradation/excretion of the substance (often due to water-insolubility)

Bagaimana Evaluasi dan Menangani Bahaya Kimia ?
Scientists use live laboratory animals, non-animal tests, case reports of poisonings, and epidemiological studies to estimate
the toxicity of chemicals, but these methods have limitations.
Many health scientists call for much greater emphasis on pollution
prevention to reduce our exposure to potentially harmful candidates.
