What is methoxychlor used for?
Methoxychlor was used as an insecticide effective against a wide range of pests including biting flies, houseflies, mosquito larvae, cockroaches, and chiggers. It was used on field crops, vegetables, fruits, stored grains, livestock, pests, homes, gardens, lakes, and marshes.
Is methoxychlor banned?
It was banned in the U.S. in 2003 due to its toxicity and ability to disrupt endocrine systems. Methoxychlor can behave like the hormone estrogen and profoundly affects the reproductive system.
What is methoxychlor in chemistry?
Summary: Methoxychlor is a manufactured chemical that does not occur naturally in the environment. Pure methoxychlor is a pale-yellow powder with a slight fruity or musty odor. Methoxychlor is used as an insecticide against flies, mosquitoes, cockroaches, chiggers, and a wide variety of other insects.
Is methoxychlor still used?
Methoxychlor is a synthetic organochloride insecticide, now obsolete.
Is methoxychlor toxic?
Toxicological Effects: Acute toxicity: Methoxychlor is practically nontoxic via the oral route, with reported oral LD50 values of 5000 to 6000 mg/kg in rats [2,9], 1850 mg/kg in mice and 2000 mg/kg in hamsters [2].
Why is methoxychlor more biodegradable than DDT?
Methoxychlor is an insecticide that was intended to take DDT's place because it is not as soluble in fatty tissues and is more readily biodegradable.
Who is invented DDT?
DDT has humble origins for a chemical that would eventually reach much of the world. First discovered in 1873 by a German chemistry student named Othmar Zeidler, the compound did not receive serious attention until a 37-year-old chemist named Paul Herman Muller synthesized it again in 1936.
What are organochlorine pesticides used for?
Organochlorine pesticides (OCPs) are man-made chemicals that were used to control insects in urban areas in Australia into the 1980s.
How is methoxychlor made?
Methoxychlor is prepared by the reaction of chloral with anisole (methyl phenyl ether) in the presence of sulfuric acid; the commercial product usually is about 88 percent pure.
Is chlorpyrifos banned?
EPA Is Banning Pesticide Chlorpyrifos On Food Crops : NPR. EPA Is Banning Pesticide Chlorpyrifos On Food Crops Agency officials issued a final ruling on Wednesday saying chlorpyrifos can no longer be used on the food that makes its way onto American dinner plates. The move overturns a Trump-era decision.
Is pentachlorophenol banned in the US?
The US National Toxicology Program lists pentachlorophenol as a “reasonably anticipated” human carcinogen. The chemical is banned under the United Nation's Stockholm Convention on Persistent Organic Pollutants, a treaty the US signed but never ratified.
How is malathion made?
Malathion is produced by the addition of dimethyl dithiophosphoric acid to diethyl maleate or diethyl fumarate. The compound is chiral but is used as a racemate.
What type of herbicide is atrazine?
Atrazine 50% WP is especially used in corn farming, it is selective/systemic herbicides & translocated both by roots and foliage. It is applied as pre emergence herbicide for annual grassy and broadleaf in crops (maize, sugarcane).
