Elements , Atoms, and Compounds

All matter, whether a solid, liquid, or gas, is made up of elements. Thus far we have identi-fied approximately 115 different elements. Many of these are familiar to us (e.g., aluminum,iron, lead, sulfur, carbon, silicon), whereas many others may not be (e.g., rhenium, thulium,terbium). An atom is the smallest unit of an element that retains the properties of that ele-ment. When an atom of one element chemically combines with atoms of the same element,a molecule is formed during this chemical reaction. When the atoms of different elementscombine during a chemical reaction, a compound is formed. Our bodies are made up of ele-ments that form inorganic and organic compounds. Of the greater than 90 naturally occur-ring elements, approximately 99% of our body weight is made up of compounds contain-ing the elements carbon, hydrogen, nitrogen, oxygen, calcium, phosphorus, and sulfur.Simple inorganic compounds such as water and sodium chloride contribute to the largerportion of the mass of our bodies when compared with organic compounds, which are ofmuch greater molecular weight than inorganic compounds. We are all familiar with manyof the important compounds that make up the body (Figure 2.1).

There are also millions of chemical compounds that have no physiological role in the body.There are greater than 6 million different chemical compounds that are known, with about80,000 that are in common industrial and household use. Many thousands of new organicchemicals are synthesized yearly. With just carbon, nitrogen, hydrogen, oxygen, and sulfur, forexample, numerous compounds can be formed, including some aromatic (=ring form) ones oftoxicological importance (Figure 2.2).

Mixtures , Suspensions, and Aerosols

The term mixture refers to any substance that contains more than one chemical compound orelement that has retained its individual properties. A mixture of alcohols, for example, may con-tain ethanol, isopropanol, and butanol all “mixed” together, giving the appearance of a singlesubstance. Each of the three components of this mixture is a pure substance, and each can be

Ident i fy ing Chemicals

Chemicals have common names, trade names, technical names, and chemical formulas associatedwith them, which can often be confusing. Manufacturers frequently choose commercial names fortheir products. This is done for obvious marketing purposes because it is easier to remember aproduct by a simple trade name than a complex chemical name. The chemical formula uses theappropriate abbreviations for the elements that are contained in the molecules of the chemical in

question, for example, sodium = Na, hydrogen = H, carbon = C, and oxygen = O. What I refer toas bicarbonate of soda may be called sodium bicarbonate by another person or sodium hydrogencarbonate by a third. We are all referring, however, to a substance that contains these four elementsthat are chemically combined into a compound containing the chemical formula NaHCO3. Inthis example, one atom each of sodium, hydrogen, and carbon and three atoms of oxygen com-bine to produce the compound. The chemical formula, however, may not be enough to indicatewhat the actual chemical is because several chemicals may share the same formula. Although thechemical formula tells us how many atoms of each element are contained within a compound, itdoes not specify the arrangement of these atoms. Different arrangements of the same types andnumbers of atoms result in different compounds. Each compound, as we will see below, is identi-fied by a different Chemical Abstracts Service (CAS) registry number. For example, C6H8O3 is aformula that is shared by several different chemicals as shown in Figure 2.3.

The chemical structure is therefore important because it shows the arrangement of atomswithin a compound, allowing us to identify the compound. The chemical structure is vitallyimportant because it can provide important clues about the potential health effects from expo-sure to that chemical. Organic chemicals contain functional groups that can often indicate thetype of toxicity one could predict from their exposure. Examples of common functional groupsin toxicants are shown in Table 2.1.

Assigning Ident i f icat ion

Perhaps the best way to identify a chemical is by its CAS registry number. This is similar tothe way a social security number identifies individuals as uniquely different. The CAS num-ber does not provide information concerning the properties of the chemical. The use of thenumber is important in overcoming any confusion about the identity of the chemical due tomultiple common, trade, and technical names. Use of the CAS number is observed in scien-tific literature and product information, including material safety data sheets. Another waythat chemicals can be identified is through the Registry of Toxic Effects of ChemicalSubstances, or RTECS, number. This registry, operated by the National Institute forOccupational Safety and Health (NIOSH), contains technical information about commonlyused industrial chemicals. There are other systems that are in use for numbering and classify-ing chemicals, including the IUPAC (International Union for Pure and Applied Chemistry),EC (assigned by the European Community), and UN numbers, or UN IDs, which are four-digit numbers that identify hazardous substances and products (such as poisonous materialsor explosives) of commercial importance. This numbering scheme is widely used in interna-

Physica l Propert ies of Chemicals

Water SolubilityWater solubility is defined as the weight (generally in grams or milligrams) of a substance thatcan be completely dissolved in 1 liter of water to form a solution. The solubility in water maygive some idea of what maximum concentrations might occur in water, whether we are referringto the body water of an organism or to an environmental body of water such as a lake.

pHA pH refers to how acid or basic (caustic) a substance is. A pH of 7 is considered neutral,whereas numbers below 7 are on the acid side of chemical neutrality and numbers above 7 areon the basic side. A pH of 1 is a very strong acid and a pH of 13 is very caustic.

Relative Molecular MassThis refers to the relative weight of a molecule of a chemical compared with the relative weightof an atom of the lightest element, hydrogen.

Octanol-to-Water Partition CoefficientThis ratio indicates how readily any chemical dissolves in a fatty or oily medium compared withwater. A very water-soluble chemical has a greater affinity for water than for octanol; thus itwould have a low partition coefficient. A pesticide with the partition coefficient of 7, for exam-ple, indicates that it is much more lipophilic (fat loving) and thus accumulates in body fat whereit may be stored for a relatively long time. The octanol-to-water partition coefficient is thereforean indicator of bioaccumulation. Chemicals that have relatively high octanol-to-water partitioncoefficients are usually absorbed quickly through the skin and enter into the blood.

Boiling Point, Melting Point, and Vapor PressureThe boiling point is the temperature at which the chemical changes from a liquid state to thegaseous state. The melting point of the chemical is the temperature at which there is a changefrom a solid to a liquid. The vapor pressure is the pressure at which the chemical in the liquid orsolid state turns into the gaseous state even at temperatures below the boiling point. Chemicalswith a high vapor pressure tend to “evaporate” more readily than others with a low vapor pres-sure and are therefore of more concern with respect to respiratory exposure.

Flash PointThe flash point is the temperature at which a substance gives off enough vapor in the air to forman ignitable mixture. The lower the flash point, the greater the risk for explosion and fire.

Autoignition Temperature and FlammabilityThe autoignition temperature is that temperature at which a substance spontaneously burns,that is, catches fire in the absence of a flame or a spark. A flammable material can be a solid, liq-uid, or gas. Something that is not flammable is not given the term inflammable. Inflammable isan older term for flammable and to avoid confusion should not be used.

Flammability (Explosive) LimitsThis represents a range of concentrations for a flammable vapor or gas in air at which an explosionmay occur in the presence of a flame or spark. The lower explosive limit (LEL)is a level belowwhich there is not enough chemical present to burn (i.e., the mixture is too lean). The upperexplosive limit (UEL) is a level above which there is too much chemical to burn (i.e., the mixtureis too rich).

Relative Density or Specific GravityThis is commonly defined as the weight of a specific volume of a liquid or solid chemical sub-stance compared with the weight of the same volume of water. More correctly, specific gravity isthe ratio of the density of a material to the density of water. The density of water is approxi-mately 1 gram per cubic centimeter. Substances with a specific gravity of less than 1 are lighterthan water and therefore float, whereas those that have specific gravities exceeding 1 are heavierthan water and thus sink. Knowing the specific gravity is important for planning spill cleanupand fire-fighting procedures.

Relative Vapor DensityThe relative vapor density refers to the weight of a specific volume of a chemical substance in thegaseous state compared with the weight of the same volume of air. From exposure viewpoint, ifthe relative vapor density is less than 1, the gas collects at the ceiling level indoors or dispersesinto the atmosphere outdoors. On the other hand, if the gas is heavier than air (that is, it has arelative vapor density of a gas greater than 1), then the gas tends to collect at floor level indoorsor in depressions outside. The possibility exists that gases having relative vapor densities greaterthan 1 may displace air in the breathing zone of confined spaces, thus leading to asphyxiation.

Odor ThresholdSome chemicals when present in the air can be smelled, and this can serve as a warning. Theodor threshold represents the smallest concentration of the chemical in the air that can be smelledand is usually expressed in parts per million or parts per billion. Some odor thresholds are suffi-ciently low enough to provide adequate warning properties (e.g., sulfur dioxide), but others arenot. It is important to realize, however, that many chemicals have no smell associated with themand thus there are no warning properties associated with odor. Other important physical prop-erties include the boiling point, vapor pressure, and melting point.

APPENDIX

2.3Regional Poison Control Centers

Regional poison control centers represent important local resources for information on the toxicproperties of chemicals, both clinical and nonclinical. They provide information to the publicon the management of suspected poisonings by animal and plants, household products, over-the-counter and prescription drugs, pesticides, or virtually any substance available. They main-tain huge databases of material safety data sheets and provide programs such as “Poisindex”whereby any published information on a chemical can be found rapidly. Regional poison con-trol centers and contact numbers are organized by state.
