According to Ngwezi, the group of chemicals consists of a mixture of organic compounds and metals namely: benzene, butadiene, carbon disulphide, chloroform, ethylene oxide, hexachlorobenzene, tetrachloroethane
, methanol, sulphur dioxide, toluene, lead, mercury and cadmium.
Associations of ASD with styrene, butadiene, and tetrachloroethane
were elevated for boys and not girls, whereas the association of ASD with mercury compounds were elevated for girls and not boys (Kalkbrenner et al.
Take contaminated fabric sample (bleached knitted) containing spots of Polypropylene and make solution of 1,1,2,2 Tetrachloroethane
as: 70% Water, 30% 1,1,2,2 Tetrachloroethane
Most commonly found chemical pollutants were benzene, benzo[a]pyrene (BaP), 1-2 dichloroethane, epichloridine, tetrachloroethane
, trihalomethane and acrylamide.
7) While PDB was the only chlorine-containing compound to be found a priority hazard, there were lots of chlorine containing chemicals lower down on the list including hexachlorobutadiene, benzyl chloride, vinyl chloride, methylene chloride, tetrachlorothene, dichloropropane, tetrachloroethane
, dichloroethane, trichloroethene, and, of course, chlorine.
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]/UV system) has been applied successfully for the removal of volatile organic contaminants (VOC) (benzene, acetone, dichloroethane, tetrachloroethane
Those that are regarded as nondegradable are chloroform, trichloroethane, and tetrachloroethane
the circadian dependent effect of trichloroethylene on spontaneous locomotor activity and of tetrachloroethane
on mortality in mice].
Phenol (AR) and tetrachloroethane
(AR) were all purchased from Tianjin Guangfu Fine Chemical Research Institute and were used as received.
Analytical grade EG, acetic anhydride, pyridine, potassium hydroxide, phenol, tetrachloroethane
(TCE), sebacic acid, glycerol, p-toluene sulphonic acid (p-TSA), zinc acetate (ZnAc), xylene, and methyl ethyl ketone (MEK) were purchased from SD Fine chemicals India and used without any further purification.
