The different classes of chemicals are discussed, including pesticides, industrial chemicals, heavy metals, organic pollutants, and others, as well as their potential effects on human health and the environment.

The textbook also offers a detailed analysis of methods for detecting, evaluating, and monitoring toxic substances in the environment, including biological and chemical tests, computer models, and experimental studies.

In addition, Environmental Toxicology also focuses on technologies and methods to reduce pollution and protect the environment. Different waste treatment methods, risk management strategies and environmental protection policies are discussed here.

In conclusion, this textbook presents current knowledge and scientific achievements in the field of environmental toxicology, while offering important guidelines for applying this knowledge to practical situations. It is an essential source of information for anyone involved in environmental protection and wanting to understand the effects of chemicals on living organisms and ecosystems.
