Chlorinated hydrocarbons (or organochlorines) are synthetic insecticides, including DDT (dichlorodiphe-nyltrichloroethane) and its relatives DDD (dichloro-diphenyl-dichloroethane) and methoxychlor, lindane, and cyclodienes such as chlordane, heptachlor, aldrin, and dieldrin. (encyclopedia.com)
A retrospective cohort study was conducted to examine the mortality of workers employed in the manufacture of the chlorinated hydrocarbon pesticides, chlordane, heptachlor, dichloro-diphenyl-trichloro-ethane (DDT) and aldrin/dieldrin/endrin. (sjweh.fi)
As at 17 May 2009, there were no Parties registered for the specific exemptions listed in Annex A pertaining to aldrin, chlordane, dieldrin, heptachlor, hexachlorobenzene, and mirex. (pops.int)
Chlordane2
EPA sampling in June 2016 and May 2018 detected aldrin, dieldrin, chlordane, p,p'-Dichlorodiphenyldichloroethane, p,p'-Dichlorodiphenyldichloroethene and p,p'-Dichlorodiphenyltrichloroethane in sediments and nearby soils above ecological screening values. (epaosc.org)
Analytical results from sediment samples collected at ten locations in the pond and its outflow feature found elevated levels of the following contaminants aldrin, dieldrin, chlordane, 4,4-DDD, 4,4-DDT, 4,4-DDE. (epaosc.org)
In the aldrin/dieldrin/endrin cohort observed deaths due to pneumonia and "other respiratory diseases" were significantly above the expected number of deaths. (sjweh.fi)

Four days before the rules went into effect, PAN Europe and the Dutch group, Natuur en Millieu , filed a legal challenge , arguing that, under the new standard, "dietary exposure to pesticides is set to rise while many residue limits will become unsafe for consumers. (panna.org)
Insecticides3
Aldrin and dieldrin (also known by their lengthy chemical names, abbreviated as HHDN and HEOD, respectively) are insecticides formerly used to control soil-dwelling and wood boring insects, including termites and ants. (purewaterproducts.com)
Aldrin and dieldrin are the common names of insecticides containing 95% HHDN and 85% HEOD, respectively. (unep.org)
All the available information on aldrin and dieldrin taken together, including studies on humans, supports the view that these chemicals make very little contribution, if any, to the incidence of cancer in humans. (purewaterproducts.com)
In Nigeria, food test carried out on 217 different food items revealed the presence of DDT, Aldrin and Dieldrin to be above maximum allowable concentration level which ranged from 1.2-2160μg kg -1 . (ajol.info)
Samples1
Analytical results from surface water samples collected in the SPA found elevated levels of dieldrin. (epaosc.org)
Epoxide2
Aldrin undergoes metabolic conversion to the epoxide, dieldrin, and because of this structural relationship, reports of the bioassays of both chemicals have been combined in this single report. (nih.gov)
We select 2*3ml 10% methanol/ether as the elution solvent for phthalates, Bisphenol A, 2,4-dichlorophenol and Nonyl phenyl, 3ml acetone and 3ml dichloromethane as the elution solvent for Hexachlorobenzene, Heptachlor epoxide and Aldrin . (youdao.com)
Possible Carcinogenicity1
Bioassays of technical-grade aldrin and dieldrin for possible carcinogenicity were conducted by administering the test materials in feed to Osborne-Mendel rats and B6C3F1 mice. (nih.gov)
19891
A reduction in aldrin and dieldrin concentrations was detected and reported in river water, sediments and fish in 1990 following the ban on the use of aldrin in May 1989 and changes in land-use in areas known to have been treated with aldrin historically. (environmentdata.org)
Pesticide3
Following detection of high aldrin and dieldrin concentrations in fish and river water in the Newlyn Catchment in 1988 enhanced routine pesticide monitoring has been carried out in this catchment. (environmentdata.org)
However, there was a marked increase in the sediment pesticide concentrations, including sites located upstream of the bulb fields treated with aldrin. (environmentdata.org)
Pentachlorophenol, aldrin, and dieldrin are classified as persistent organic pollutants under the Stockholm Convention. (iarc.fr)
Concentrations1
A further reduction in aldrin and dieldrin concentrations in river water occurred during 1991 and no failure of the relevant Environmental Quality Standard (EQS) was recorded in the Newlyn Catchment in 1991. (environmentdata.org)
Examples1
An overview of the ecologic and health effects of aldrin and dieldrin provides examples of how to streamline some of the programs and improve access to mutually useful scientific data. (nih.gov)
Dieldrin is a chlorinated hydrocarbon originally produced by Bayer AG as an insecticide. (the-medical-dictionary.com)
Originally developed in the 1940s as an alternative to DDT, dieldrin proved to be a highly effective insecticide and was very widely used during the 1950s to early 1970s. (the-medical-dictionary.com)
Review2
Aldrin and dieldrin: a review of research on their production, environmental deposition and fate, bioaccumulation, toxicology, and epidemiology in the United States. (nih.gov)
This review is a detailed examination of 2 of the 12 POPs, aldrin and dieldrin, and how scientific groups identify and measure their effects. (nih.gov)
Groups4
Groups of 50 rats of each sex were administered aldrin at one of two doses, either 30 or 60 ppm. (nih.gov)
Groups of 50 mice of each sex were administered aldrin at one of two doses for 80 weeks, then observed for 10-13 weeks. (nih.gov)
Aldrin produced no significant effect on the mortality of rats or of male mice, but there was a dose-related trend in the mortality of female mice, primarily due to the early deaths in the high-dose groups. (nih.gov)
Groups of 50 rats and 50 mice of each sex were administered dieldrin at one of two doses. (nih.gov)
