Health Risk Assessment of Heavy Metals at Drinking Water Sources in Kaifeng
摘要
Abstract
The health risks of heavy metals at drinking water sources ( Hei Lake and Liu Lake ) in Kaifeng city were assessed initially.The results indicated that the grade of the health risk caused by carcinogens Cr 6+and Cd was 10-6 a-1 ~10 -5 a-1 , which was lower than the maximum allowance level (1.0 ×10 -4 a-1 ) recommended by United States Environmental Protection Agency (USEPA), but was close to the maximum acceptable risk level (5.0 ×10 -5a-1) recommended by International Commission on Ra-diological Protection (ICRP).However, in comparison with the maximum acceptable risk level (1.0 ×10-6a-1) recommended by Swedish Environmental Protection Agency , and Netherlands Construction and Environmental Agency , the health risk values caused by the chemical carcinogens in various sampling spots of Hei Lake and Liu Lake all exceeded this standard , and the maximum health risk value for Hei Lake and Liu Lake exceeded the standard by 89.7 times and 95.2 times, respectively.The grade of the health risk caused by non-carcinogens Pb , Cu and Zn ranged from 10 -13 a-1 to 10 -8 a-1 , which was much lower than the above three risk limits.Therefore, Cr6+and Cd should be emphatically monitored as priority pollutants .关键词
