Endocrine disrupting chems. are exogenous chems. which alter the functions of endocrine system. There are very few studies of occurrence and distribution of endocrine disrupting chems. in water, soil and their potential human health risks under Indian conditions. In the present work, occurrence of eleven endocrine disrupting chems. namely bisphenol-A, triclosan, triclocarbon, 4-nonylphenol, 4-tert octylphenol, Me paraben, Pr paraben, Bu paraben, benzyl Bu phthalate, di (2-ethylhexyl) phthalate and di-Bu phthalate have been investigated in 20 river water samples, 5 ground water samples and 23 agricultural soil samples collected from 26 sampling points of different agro-climatic zones of India during 2019-2020. Instrument detection and quantification limits of different endocrine disrupting chems. using LC-MS/MS varied from 0.001 to 0.05 and 0.005-0.1 μg/mL, resp. Detection frequencies of bisphenol A, 4-nonylphenol, 4-tert octylphenol and di-Bu phthalate were 100% in river water samples. In ground water samples di-Bu phthalate, benzyl Bu phthalate, di (2-ethylhexyl) phthalate, triclosan, triclocarbon, 4-tert octylphenol, 4-nonylphenol, Pr paraben and Bu paraben and in soils 4-tert octylphenol, 4-nonylphenol, bisphenol-A and di-Bu phthalate were detected in 100% sample. High mean concentrations of di (2-ethylhexyl) phthalate were recorded in river waters (2706.135 μg/L), ground waters (3203.33 μg/L) and agricultural soils (1005.490 ng/g). Other chems. detected in high concentrations were 4-tert octylphenol (180.680-829.93 μg/L), di-Bu phthalate (117.492-182.29 μg/L) and bisphenol-A (13.99-228.03 μg/L). Widespread distribution and high concentrations of these chems. in water and soil is a cause of concern and, therefore, continued monitoring of these chems. in different environmental matrixes is the need of the hour. In the experiment, the researchers used many compounds, for example, 1-(4-Chlorophenyl)-3-(3,4-dichlorophenyl)urea (cas: 101-20-2Recommanded Product: 1-(4-Chlorophenyl)-3-(3,4-dichlorophenyl)urea).
1-(4-Chlorophenyl)-3-(3,4-dichlorophenyl)urea (cas: 101-20-2) belongs to organic chlorides. Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.Recommanded Product: 1-(4-Chlorophenyl)-3-(3,4-dichlorophenyl)urea
