There is a tendency to believe that if only small amounts of a chemical are needed to cause poisoning, then the risks associated with exposure to the chemical are very high. This case is not necessarily so. A high toxicity chemical can have a low risk to health if it is used with proper precautions. On the other hand, it is possible that a chemical of low toxicity may present a high risk to health if it is used inappropriately or incorrectly. Toxicity is a measure of the poisoning strength and is an unchanging characteristic of a chemical.

Risk is not the same. It is a variable feature. Risk is defined as the combination of the likelihood of the occurrence of a harm and the severity of that harm. Risk, in this discussion, is the likelihood that a chemical will cause poisoning, given its toxicity strength, and the amounts and manner in which it is used, stored and handled. The toxicity hazard of a chemical cannot be changed, but the risk it presents can be controlled and minimized.

These factors are as follows: Route of entry into the body Amount or dose entering the body Toxicity of the chemical Removal from the body Biological variation.

No chemical can cause poisonous effects without first coming into contact with the body. As a general rule there is less risk of chemically caused harm if the body can do one or both of the following: break down the chemical into less harmful chemicals rapidly remove the chemical from the body. There are two main ways that too much of a chemical can enter the body and cause poisonous effects: By sudden or short term-exposures A one-time exposure to relatively large amounts of the chemical can overwhelm the body.

Some examples of acute toxicity are listed below: Inhalation of high concentrations of acid vapours might cause serious burns of the mouth and the airways leading to the lungs. Skin contact with certain organic solvents that are absorbed through the skin may cause dizziness and nausea. Inhalation of dusts can cause irritation of the respiratory tract, dryness in the throat, and coughing. By repeated exposures over a long period of time A repeated exposure over a long period of time can also cause too much chemical to enter the body and produce poisoning.

The following are some examples of chronic toxicity: Inhalation of certain acid vapours at concentrations may, over long periods of time, cause loss of tooth enamel, eventually leading to extensive tooth decay.

Inhalation and skin absorption of some organic solvents may, over long periods of time, cause damage to nerve tissue. Repeated exposure to dusts containing quartz can cause scar tissue in the lungs. This effect eventually leads to severe and permanent lung damage.

Acute toxicity In most cases, much more is known about the acute toxicity of a chemical than its chronic toxicity. Chronic toxicity Much of the knowledge we have about chronic toxicity comes from animal experiments. Some poisons make an organism sick, others may cause it to die and yet others may lead to subtle changes in health that may not be noticed for years.

Toxicology is the science of poisons. It is the study of harmful effects of chemicals on living organisms. Potentially poisonous chemicals can be synthetic manufactured or natural. For example, dioxins, some pesticides and nerve gases are poisonous manufactured chemicals, whereas, belladonna, botulinum and tetrodotoxin are poisonous naturally produced chemicals. There are also poisonous substances that occur naturally in the ground, such as asbestos and lead.

In science, a toxin is often considered a specific type of poison — a poisonous substance produced within living cells or organisms. Venoms are toxins that are injected by a bite for example, from a spider or sting for example, from a wasp to cause their effect.
