What are chemical hazards and toxic substances? Chemical hazards and toxic substances pose a wide range of health hazards (such as irritation, sensitization, and carcinogenicity) and physical hazards (such as flammability, corrosion, and explosibility).

A toxicant is any toxic substance, whether artificial or naturally occurring. [1] By contrast, a toxin is a poison produced naturally by an organism (e.g. plant, animal, insect, bacterium). [2] The different types of toxicants [3] can be found in the air, soil, water, or food. [4]

Toxicity is the degree to which a chemical substance or a particular mixture of substances can damage an organism. [1] Toxicity can refer to the effect on a whole organism, such as an animal, bacterium, or plant, as well as the effect on a substructure of the organism, such as a cell (cytotoxicity) or an organ such as the liver (hepatotoxicity).

WHO provides scientific evidence and risk management recommendations for 10 chemicals or groups of chemicals of major public health concern. Air pollution kills an estimated seven million people worldwide every year. WHO data shows that 9 out of 10 people breathe air containing high levels of pollutants.

Toxicant, toxin, and poison are often used interchangeably in the literature but there are subtle differences as shown below: Toxicants: Substances producing adverse biological effects of any kind. May be chemical or physical in nature. Effects may be acute or chronic. Toxins: Peptides or proteins produced by living organisms.

There are a number of chemical substances in the environment — some of these are-toxic and rest non-toxic. The toxicants are released from various sources into air, water and soil.
