Environmental toxicology is the study of the effects of toxic substances on living organisms, including humans, animals, and plants.

Oxygen is not a pollutant because it is a natural component of the environment and is essential for life.

Biomagnification is the process by which toxic substances increase in concentration as they move up the food chain.

Exposure to environmental pollutants can cause a variety of health effects, including cancer, neurological damage, and reproductive problems. Improved immune function is not a known health effect of exposure to environmental pollutants.

The primary goal of environmental toxicology research is to understand the effects of toxic substances on living organisms. This information can then be used to develop new methods for cleaning up contaminated sites, create new regulations for the use of chemicals, and educate the public about environmental hazards.

Natural disasters are not a common source of environmental pollution. Industrial activities, agricultural practices, and transportation are all common sources of environmental pollution.

Biodegradation is the process by which toxic substances are broken down into less harmful substances by microorganisms.

Intelligence test is not a type of environmental toxicology test. Acute toxicity test, chronic toxicity test, and teratogenicity test are all types of environmental toxicology tests.

Ecotoxicology is the study of the effects of toxic substances on ecosystems.

Computer model is not a type of environmental toxicology model. Animal model, plant model, and microorganism model are all types of environmental toxicology models.

Environmental fate is the process by which toxic substances are transferred from one environmental compartment to another.

Social risk assessment is not a type of environmental toxicology risk assessment. Ecological risk assessment, human health risk assessment, and economic risk assessment are all types of environmental toxicology risk assessment.

Human toxicology is the study of the effects of toxic substances on human health.

Land use planning regulations are not a type of environmental toxicology regulation. Emission standards, effluent standards, and product safety standards are all types of environmental toxicology regulations.

Animal toxicology is the study of the effects of toxic substances on animals.
