Abstract |
This study assesses the scientific and technical information available on a class of potential multimedia environmental pollutants, the nonfluorinated halomethanes. This class of compounds includes the chlorinated, brominated, and iodinated methanes, and a few compounds containing two different halogens, such as bromodichloromethane. Of these compounds, the report considers chloroform and carbon tetrachloride in the greatest detail, primarily because the data available on these chemicals are more extensive than on other halomethanes, and they have been shown to be carcinogenic when administered in high doses to test animals. |
