Ecotoxicology is the study of the effects of toxic chemicals on biological organisms, especially at the population, community, ecosystem, and biosphere levels. Ecotoxicology is a multidisciplinary field , which integrates toxicology and ecology .
Ecotoxicity, the subject of study in the field of ecotoxicology (a portmanteau of ecology and toxicology), refers to the biological, chemical or physical stressors that affect ecosystems. Such stressors can occur in the natural environment at densities, concentrations, or levels high enough to disrupt natural biochemical and physiological ...
[1] [2] Ecotoxicology is a subdiscipline of environmental toxicology concerned with studying the harmful effects of toxicants at the population and ecosystem levels. Rachel Carson is considered the mother of environmental toxicology, as she made it a distinct field within toxicology in 1962 with the publication of her book Silent Spring , which ...
René Truhaut (May 23, 1909 – May 10, 1994) was a French toxicologist. He was made chairman of the department of toxicology at the Paris Faculty of Medicine.He is known for having introduced the concept of daily intake in 1956, and for coining the term "ecotoxicology" (in 1969) which defined it as "the branch of toxicology concerned with the study of toxic effects, caused by natural or ...
A toxicologist working in a lab (United States, 2008)Toxicology is a scientific discipline, overlapping with biology, chemistry, pharmacology, and medicine, that involves the study of the adverse effects of chemical substances on living organisms [1] and the practice of diagnosing and treating exposures to toxins and toxicants.
Ecotoxicology and Environmental Safety is an open-access peer-reviewed scientific journal published by Elsevier. The editors-in-chief are Richard Handy ( University of Plymouth ) and Bing Yan ( Guangzhou University ).
ecotoxicology The study of the ecological role of toxic chemicals (often pollutants, but also naturally occurring compounds). ecozone An area that has characteristics of natural origin such as climate, terrain, vegetation, etc. It may used as a synonym for biogeographic realm. El Niño
[1] [2] [3] PNEC values are often used in environmental risk assessment as a tool in ecotoxicology. [1] [3] [4] A PNEC for a chemical can be calculated with acute toxicity or chronic toxicity single-species data, Species Sensitivity Distribution (SSD) multi-species data, field data or model ecosystems data. Depending on the type of data used ...
