ATSDR - ToxFAQs™: Dichlorobenzenes (1140 words) |
 | Dichlorobenzenes in soil usually are not easily broken down by soil organisms. |
| Children who are exposed to dichlorobenzenes are likely to exhibit the same effects as adults, although this is not known for certain. |
| There is no reliable evidence suggesting that dichlorobenzenes cause birth defects, although animal data raise concern for effects of 1,4-dichlorobenzene on postnatal development of the nervous system. |
| 1,4-Dichlorobenzene - PSL1 (4094 words) |
| Based on analysis of dichlorobenzenes in the water supplies of three cities in Ontario, Oliver and Nicol (1982) concluded that most of the dichlorobenzene present in drinking water occurs as the 1,4-isomer, due probably to its release into surface water from urinal deodorant blocks. |
| The 1,4-isomer of dichlorobenzene was detected in 4 of 143 samples of raw and treated water collected in Quebec in May 1985, and February and July 1986 at concentrations below 1 mg/L (detection limit = 0.1 mg/L) [Vachon, 1986]. |
| Durham and Oliver (1983) examined the vertical distribution of 1,4-dichlorobenzene in bottom sediments in Lake Ontario near the mouth of the Niagara River in 1981, and reported that the maximum concentration of 1,4-dichlorobenzene was 1 100 ng/g (dry weight) at a depth from 8 to 9 cm. |
