They negatively affect multiple levels, ranging from molecules, to tissues, to organs; to individuals, to populations, and onto communities. In the natural environment, a combination of pesticide exposure and natural stressors such as fluctuating temperature, food shortages, or decreased oxygen availability are worse than when presented alone.
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 ...
Ecotoxicology differs from environmental toxicology in that it integrates the effects of stressors across all levels of biological organisation from the molecular to whole communities and ecosystems, whereas environmental toxicology includes toxicity to humans and often focuses upon effects at the organism level and below.

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]

Acceptable daily intake or ADI is a measure of the amount of a specific substance (originally applied for a food additive, later also for a residue of a veterinary drug or pesticide) in food or drinking water that can be ingested (orally) daily over a lifetime without an appreciable health risk.

This data is frequently screened for quality, relevancy and ideally contains data for species in multiple trophic levels and/or taxonomic groups. [1] [6] The lowest LC50 in the compiled database is then divided by the assessment factor to calculate the PNEC for that data. The assessment factor applied to acute toxicity data is typically 1000 ...
Exposure assessment is a branch of environmental science and occupational hygiene that focuses on the processes that take place at the interface between the environment containing the contaminant of interest and the organism being considered. These are the final steps in the path to release an environmental contaminant, through transport to its ...
