Industry and toxins go together, Industries being run primarily for profit, discharge their harmful chemicals into the environment causing serious effects on living and to some extent non-living icons of the earth, effecting the natural balances of life. Thought all humans and animals as well as plants do not manifest the effect readily because of their individual tolerance levels.
The potential toxicity (harmful action) inherent in a substance is manifest only when that substance comes in contact with that susceptible living biological system. A chemical normally thought of as "harmless" will evoke a toxic response if added to a biological system in sufficient amount. The toxic potency of a chemicals is defined by the relationship between dose (the amount) of the chemical and the response that is produced in a biological system. The toxicity of industrial wastes is not often managed and it has caused serious damage to earth and water.
The book starts detailing the topics generation of industrial waste and toxins and proceeds to describe industrial chemical of common use and combined actions of chemicals in mixture.
Characterization of risk by industrial effluents is shown in the chapter risk characterization and industrial toxins.
