Abstract |
Occupational and environmental toxicologists are faced with the responsibility of providing sound scientific data that can be used to ensure individuals that they can conduct their daily activities without undergoing any undue risk which might potentiate the development of disease. With the majority of chemicals in the environment, it has been generally assumed that there is some safe level of exposure that is of no threat to human health. To be able to predict the absolute safe level is the sought after goal; however, the possibility of achieving this level of precision is remote, and in fact no chemical is absolutely safe. Thus, it becomes vitally important to carefully define the population at risk, the mode of exposure, and the lowest concentration that will cause an adverse health effect. |
