Use of environmentally persistent polybrominated diphenyl ether (PBDE) flame retardants has been reduced because of concerns about health effects, but potential health effects of organophosphate (OP) flame retardants used as alternatives to PBDEs have not been extensively investigated, despite evidence of widespread human exposure. Meeker and Stapleton (p.
Recent studies have indicated that organophosphorus pesticides (OPs) may disrupt metabolism by altering the expression or function of adenylyl cyclase (AC; the enzyme that catalyzes the formation of cAMP from ATP) or G-proteincoupled receptors and G-proteins involved in the AC signaling cascade.
Oxidative stress status and Acetylcholinesterase (AChE) activity were studied in blood samples obtained from 61 agricultural workers engaged in spraying organophosphorus (OP) insecticides in the mango plantation, with a minimum work history of one year, in the age range of 12-55 years. Controls were age-matched, unexposed workers, who never had any exposure to OP pesticides.
Organophosphates include insecticides like malathion, parathion and fenthion, which are widely used in developing countries like India. The pesticides inhibit the activity of the enzyme acetylcholinesterase. The enzyme breaks down the neurotransmitter acetylcholine, which transmits impulses from brain and to the body. Breakdown of acetylcholine signifies the end of a transmission. This is
More studies needed on pralidoxime, a drug used to treat pesticide poisoning a team of two drugs is prescribed by who to combat organophosphorous pesticide poisoning. The most widely used class of pesticides, it causes about 200,000 deaths each year, globally. Now, one of the two drugs has come under the scanner because various studies have found it to be ineffective and harmful.
AHMEDABAD: It was rotla poisoning that killed three children in Chainpura, Ranip on Wednesday. Investigations have revealed that bajra rotlas served to the affected children were made of flour that contained crushed pesticide tablets.
This information bulletin provides a list of maximum residue limits (MRLs) for pesticides registered for use in Australian on almonds. Listed in the table are MRLs for Australia, as
carp, the freshwater fish species, are going blind in Punjab. The reason, a study reveals, is a pesticide used in rice fields nearby. Monocrotophos, the pesticide, causes a cataract-like condition reducing the economic value of the fish, said Punjab University researchers who carried out the study. The study was initiated after fish farmers from Patiala and Sangrur districts took their complaint
The present studies are based on the feedback provided by Punjab fish farmers practising composite fish culture of Indian major and exotic carps. According to them, during the southwest monsoon, in ponds in the vicinity of toxicant (monocrotophos)-treated paddy fields, the eye lens of most of the culturable fishes became opaque. As a result, there was drastic decrease in the acceptability of supplementary feed, resulting in poor overall growth both in weight and length.
