Pesticides can enter the body through inhalation of aerosols, dust and vapor that contain pesticides; through oral exposure by consuming food/water; and through skin exposure by direct contact. [96] Pesticides secrete into soils and groundwater which can end up in drinking water, and pesticide spray can drift and pollute the air.
Health effects of pesticides may be acute or delayed in those who are exposed. [1] Acute effects can include pesticide poisoning, which may be a medical emergency. [2] Strong evidence exists for other, long-term negative health outcomes from pesticide exposure including birth defects, fetal death, [3] neurodevelopmental disorder, [4] cancer, and neurologic illness including Parkinson's disease ...
Pesticide poisoning is an important occupational health issue because pesticides are used in a large number of industries, which puts many different categories of workers at risk. Extensive use puts agricultural workers in particular at increased risk for pesticide illnesses.
Overview of the interdisciplinarity of environmental toxicology Categories of organisms commonly used for assessing environmental toxicity. 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.
In 2016 insecticides were estimated to account for 18% of worldwide pesticide sales. [2] Worldwide sales of insecticides in 2018 were estimated as $ 18.4 billion, of which 25% were neonicotinoids, 17% were pyrethroids, 13% were diamides, and the rest were many other classes which sold for less than 10% each of the market.

Pesticide application is the practical way in which pesticides (including herbicides, fungicides, insecticides, or nematode control agents) are delivered to their biological targets (e.g. pest organism, crop or other plant).

[35] Pentachlorobenzene (PeCB), is a pesticide and unintentional byproduct. PeCB has also been used in PCB products, dyestuff carriers, as a fungicide, a flame retardant, and ...
Pesticide application can artificially select for resistant pests. In this diagram, the first generation happens to have an insect with a heightened resistance to a pesticide (red) After pesticide application, its descendants represent a larger proportion of the population, because sensitive pests (white) have been selectively killed.
