Dichlorophenols included 2,5-dichlorophenol, a metabolite of 1,4-dichlorobenzene
used in mothballs; indoor deodorizers; toilet bowl disinfectants; and 2,4-dichlorophenol, a metabolite of 2,4-dichlorophenoxyacetic acid used as intermediate in the production of some herbicides.
2]S-related mitigation of developmental inhibition caused by the organic pollutant, 1,4-dichlorobenzene
Case studies are provided on the ecotoxicological concerns and regulatory status of four specific chemicals: orthonitrochlorobenzene, 1,4-dichlorobenzene
, hexachlorobenzene, and microbeads.
a]) of the target compounds Chemical name p-dichlorobenzene, p-chloro-m-cresol, 4- and 1,4-dichlorobenzene

dagger]) Anthracene, chlorpyrifos, diazinon, isopropylbenzene, 2,6-dimethylnaphthalene, 1,4-dichlorobenzene
, bromacil, 3-t-butyl-4-hydroxyanisole, isopropylbenzene, 4-cumylphenol, and 4-n-octylphenol were not detected in samples.
Decreased hepatic CAT activities was noted in Anguilla Anguilla pre-exposed to beta-naphthoflavone , in goldfish during chronic exposure to 2,4 dichlorophenol  and in Jenynsia multidentata exposed to 1,2- and 1,4-dichlorobenzene
Because it is highly flammable, toxic and carcinogenic (IARC, 2002), naphthalene was replaced by 1,4-dichlorobenzene
in mothball production; even then, mothballs should never be stored in places accessible to children or pets.
A case in point is 1,4-dichlorobenzene
, a compound used in many air freshners, toilet bowl deodorizers, and moth repellants.
The thimble, containing the sample, was then placed in a Soxhlet extraction apparatus, 20 mL of 1 mg/mL of 1,4-dichlorobenzene
was added to monitor recovery efficiency, and the sample was extracted with 180 mL methylene chloride for 16 hours.
This list includes the pesticides 1,4-dichlorobenzene
, pentachlorophenol, and tributyl tin; the industrial chemicals 3,3'-dichlorobenzidine and 4,4'-methylenebis(2-chloroaniline); and the entire class of PAHs.
In addition to methane and TNMHC, 16 hydrocarbon species were selected and used to calculate percent control efficiency including freon, methylene chloride, 1,1,1-trichloroethane, tetrachloroethane, trimethylbenzenes, 1,4-dichlorobenzene
, toluene, xylenes, and ethylbenzene.
2,5-Dichlorophenol (2,5-DCP) is a major metabolite of 1,4-dichlorobenzene
(1,4-D), which has been used as a chemical intermediate for the manufacture of dyes and pharmaceutical and agricultural products, as a moth repellent, and as a space deodorant for industrial and indoor home applications [Hazardous Substances Data Bank (HSDB) 2014; International Programme on Chemical Safety (IPCS) 1989].
