Dieldrin - an overview | ScienceDirect Topics
As dieldrin was manufactured as an insecticide, sediment-dwelling aquatic microinvertebrates (insects, e.g., midges) are very sensitive to dieldrin. In species that are particularly sensitive to dieldrin, the differences between concentrations causing acute lethality and chronic toxicity are small, with acute–chronic ratios ranging from 2.4 ...
Dieldrin - an overview | ScienceDirect Topics
Dieldrin has a half-life of approximately three hundred days in the human body (Kanthasamy et al., 2005). As a result, dieldrin has a tendency to accumulate in the body and pose health risks. Exposure to certain pesticides, including dieldrin, has been linked to Parkinson’s disease (Hatcher et al., 2007). However, research has not been able ...
Dieldrin - an overview | ScienceDirect Topics
Dieldrin is a synthetic organochlorine insecticide that was primarily used on crops, and it inhibits the function of the central nervous system, causing convulsions in humans at high concentrations. AI generated definition based on: Encyclopedia of Toxicology (Third Edition), 2014
Dieldrin - an overview | ScienceDirect Topics
Dieldrin was widely used as an insecticide around the world until the middle 1970s, mainly for the control of soil pests, such as termites, grasshoppers, locusts, beetles, and textile pests, and for the treatment of seeds. Dieldrin was a very effective soil insecticide, especially for perennial crops, such as sugar cane, palm, and banana.
Dieldrin - an overview | ScienceDirect Topics
Dieldrin is a synthetic organochlorine insecticide that persists in soils for up to 5 years, showing moderate to significant bioaccumulation in aquatic species. It inhibits GABA-regulated chloride transport, leading to hyperexcitability of the central nervous system and convulsions in humans at high concentrations.
Dieldrin - an overview | ScienceDirect Topics
Dieldrin was a very effective soil insecticide, especially for perennial crops, such as sugar cane, palm, and banana. Dieldrin has also been used to control tsetse flies and other vectors of tropical diseases, including malaria, yellow fever, Chagas disease, Oraya fever, African sleeping sickness, river blindness, and filariasis (de Jong, 1991 ...
Dieldrin - an overview | ScienceDirect Topics
Dieldrin has a log octanol–water partition coefficient of 6.2 and a density of 1.75 g cc −1 at 20 °C. Partition Behavior in Water, Sediment, and Soil. Consistent with its intended use on insects in soil, dieldrin is not very water soluble. However, dieldrin readily binds to sediment, but rarely leaches into deeper soil layers and groundwater.
Status of Dieldrin in vegetable growing soils across a peri-urban ...
2022年2月15日 · Dieldrin concentration depended on both grain size (P = 0.04) and SOM content in each fraction (P < 0.001). Indeed, the strong relationship between Dieldrin and SOM showed a significantly higher intercept for coarse sand (0.88) in comparison to the ones of fine sand (0.03) and silts and clay (0.06), which are not significantly different.
Aldrin - an overview | ScienceDirect Topics
Aldrin is an organochlorine pesticide related to dieldrin. Following initial phase out was retained as an anti-termite treatment until 1987. The only difference between the structures of aldrin and dieldrin is the presence, in dieldrin, of an epoxied ring at the site of one of the carbon–carbon double bonds in aldrin.
Wildlife Toxicity Assessment for Aldrin and Dieldrin
2015年1月1日 · Brains of Snow Geese found moribund had an average concentration of 8.2 ppm dieldrin, while brains of a subset of dead birds averaged 14.1 ppm dieldrin. Flickinger cites an earlier monograph by Stickel et al. [ 24 ] to support a lower limit 4 to 5 ppm for the lethal level of dieldrin in brains of experimental and wild birds; this level agrees ...
