Malathion is a pesticide that is widely used in agriculture, residential landscaping, public recreation areas, and in public health pest control programs such as mosquito eradication. [5] In the US, it is the most commonly used organophosphate insecticide.
DDT and DDE are resistant to metabolism; in humans, their half-lives are 6 and up to 10 years, respectively. In the United States, these chemicals were detected in almost all human blood samples tested by the Centers for Disease Control in 2005, though their levels have sharply declined since most uses were banned.

Malaoxon (Liromat, Malation oxon, Malthon oxon) is a chemical compound with the formula C 10 H 19 O 7 PS. More specifically, it is a phosphorothioate. It is a breakdown product of, and more toxic than, malathion.
Benzyl benzoate is an effective and inexpensive topical treatment for human scabies. [7] It has vasodilating and spasmolytic effects and is present in many asthma and whooping cough drugs. [8] It is also used as an excipient in some testosterone -replacement medications (like Nebido) for treating hypogonadism. [9]
The acute toxicity of pesticides on bees, which could be by contact or ingestion, is usually quantified by LD 50. 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 ...
Infobox references. Isomalathion is an impurity found in some batches of malathion. Whereas the structure of malation is, generically, RSP (S) (OCH 3) 2, the connectivity of isomalathion is RSPO (SCH 3) (OCH 3). It arises by heating malathion. Being significantly more toxic to humans than malathion, it has resulted in human poisonings.
Human exposure to methoxychlor occurs via air, soil, and water, [8] primarily in people who work with the substance or who are exposed to air, soil, or water that has been contaminated. It is unknown how quickly and efficiently the substance is absorbed by humans who have been exposed to contaminated air or via skin contact. [ 8 ]
Cypermethrin (CP) is a synthetic pyrethroid used as an insecticide in large-scale commercial agricultural applications as well as in consumer products for domestic purposes. It behaves as a fast-acting neurotoxin in insects. It is easily degraded on soil and plants but can be effective for weeks when applied to indoor inert surfaces.
