This ultimately affects all living organisms that comprise an ecosystem. Ecotoxicology has been defined as a branch of toxicology that focuses on the study of toxic effects, caused by natural or synthetic pollutants. These pollutants affect animals (including humans), vegetation, and microbes, in an intrinsic way. [1]
Biological hazards, also known as biohazards, are organic substances that pose a threat to the health of living organisms, primarily humans. This can include medical waste, samples of a microorganism, virus, or toxin (from a biological source) that can impact human health. Biological hazards can also include substances harmful to animals.

[4] [5] [6] Small animals, such as helminths and insects, can also cause or transmit disease. However, these animals are usually referred to as parasites rather than pathogens.
