A combination of benzene (5.0 mg/l) or cadmium (0.01 mg/l) with nitrosodimethylamine (drinking water, 9 months) produced a significantly higher tumor incidence in female CBA X C57B1/6 mouse hybrids. The said agents are capable of modifying the carcinogenicity of other substances when present in water in concentrations exceeding the permissible one.
苯（5.0毫克/升）或镉（0.01毫克/升）与亚硝基二甲胺联用（饮用水，9个月），使雌性CBA X C57B1/6小鼠杂交种的肿瘤发生率显著升高。当上述物质在水中的浓度超过允许浓度时，它们能够改变其他物质的致癌性。
