Malathion is also used in conjunction with diesel fuel to fog an area where there is an infestation of mosquitoes. By diluting the mixture, it becomes much weaker. It is possible to dilute the mixture to the point where mosquitoes are not killed, but become more resistant to the mixture, making it less effective in subsequent foggings.
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.
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. [1]
The relations between ancient Indonesia and Vietnam, particularly Southern Vietnam, began around the 7th century, since the era of the Champa, Srivijaya, and later Majapahit kingdoms. [1]: 225 In mid-11th century, Vietnamese king Ly Thanh Tong (r. 1054–1071) was said to have purchased a precious pearl from a Javanese merchant.
The Vietnamese Wikipedia initially went online in November 2002, with a front page and an article about the Internet Society.The project received little attention and did not begin to receive significant contributions until it was "restarted" in October 2003 [3] and the newer, Unicode-capable MediaWiki software was installed soon after.
Symptoms of exposure to this type of compound include cholinesterase inhibition, miosis, frontal headache, increased bronchial secretion, nausea, vomiting, sweating, abdominal cramps, diarrhea, lacrimation, increased salivation, bradycardia, cyanosis and muscular twitching of the eyelids, tongue, face and neck, possibly progressing to convulsions.
