Environmental toxicology is a multidisciplinary field of science concerned with the study of the harmful effects of various chemical, biological and physical agents on living organisms. [ 1 ] [ 2 ] Ecotoxicology is a subdiscipline of environmental toxicology concerned with studying the harmful effects of toxicants at the population and ...
A key environmental concern involves polycyclic aromatic hydrocarbons (PAHs), which "accumulate on particles and sediments, shielding them from biodegradation," according to Green and Trett. [ 7 ] In one study, samples were collected from four sites (13 stations) in the Amazon where crude oil was the main pollutant.
Ecotoxicology is a relatively young discipline that made its debuts in the 1970s [2] in the realm of the environmental sciences. Its methodological aspects, derived from toxicology, are widened to encompass the human environmental field and the biosphere at large.
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). Established in 1977, the journal has published in open-access since 2021. [1]
Environmental chemists draw on a range of concepts from chemistry and various environmental sciences to assist in their study of what is happening to a chemical species in the environment. Important general concepts from chemistry include understanding chemical reactions and equations , solutions , units , sampling , and analytical techniques .
Environmental hazards are hazards that affect biomes or ecosystems. [1] Well known examples include oil spills , water pollution , slash and burn deforestation, air pollution , ground fissures , [ 2 ] and build-up of atmospheric carbon dioxide . [ 3 ]
A box model explaining the processes of toxicokinetics and toxicodynamics. While toxicokinetics describes the changes in the concentrations of a toxicant over time due to the uptake, biotransformation, distribution and elimination of toxicants, toxicodynamics involves the interactions of a toxicant with a biological target and the functional or structural alterations in a cell that can ...
The GLBNS is administered by the U.S Environmental Protection Agency (USEPA) and Environment Canada. [3] Following the GLBNS, the Multimedia Strategy for Priority Persistent, Bioaccumulative and Toxic Pollutants (PBT Strategy) was drafted by the USEPA. [3] The PBT Strategy led to the implementation of PBT criteria in several regulational policies.
