Parathion methyl, or methyl parathion, is an organophosphate insecticide, possessing an organothiophosphate group. It is structurally very similar to parathion-ethyl . It is not allowed for sale and import in nearly all countries around the world, while a few allow it under subject to specified conditions only.
Parathion, also called parathion-ethyl or diethyl parathion, is an organophosphate insecticide and acaricide.It was originally developed by IG Farben in the 1940s. It is highly toxic to non-target organisms, including humans, so its use has been banned or restricted in most countries.
This resulted in a 10-year review process of the health and environmental effects of all pesticides, beginning with the organophosphates. As part of that process, in 1999 the EPA announced a ban the use of organophosphate pesticide methyl parathion and significant restrictions on the use of another OP, azinphos methyl , in what they called "kid ...
In 1999, the EPA banned most uses of methyl parathion and azinphos methyl, citing the risks they pose to children. [18] Both methyl parathion and azinphos methyl are organophosphates. Organophosphates are pesticides that kill insects by disrupting nerve impulses. Unfortunately, these pesticides have the same effect on humans.
Acute toxicity of pesticides causes a range of effects on bees, which can include agitation, vomiting, wing paralysis, arching of the abdomen similar to sting reflex, and uncoordinated movement. Acute toxicity may depend on the mode of exposure, for instance, many pesticides cause toxic effects by contact while neonicotinoids are more toxic ...
The situation in vector control is fairly similar, despite different risk trade-offs, [56] with the global use of organophosphate insecticides falling by nearly half between 2010 and 2019. [28] Pirimiphos-methyl, Malathion and Temefos are still important, primarily for the control of malaria in the Asia-Pacific region. [28]
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.
At normal conditions, it is a pale yellow mobile liquid poorly soluble in water but readily soluble in organic solvents.It is relatively stable and hydrolyses only at very acidic or basic conditions.
