| 中文摘要 |
| 在松花江主要污染源根治汞8年后渔民发汞较70年代下降78.30%-82.57%,较80年代初下降71.48%.取得了明显的健康效益与环境效益。但至今该地区渔民的发汞值仍超过国家诊断标准。这些渔民发汞仍显着地高于非汞污染区渔民,并有1.92%渔民的发汞值仍超过国家诊断标准。这些渔民主要分布在三岔河口以下的第一松花江段,而在二松渔民中发汞超过标准者极少,并对其原因作了讨论。 |
| 英文摘要 |
| Since the major sources of mercury pollution in the Songhuajiang River were eliminated & years ago,the level of mercury in the hairs of fishmen living along the river has reduced by 78.30%-82.5% as compared with that in the 1970s,and by 71.48 % as compared with that in the early 1980s,showing that obvious health benefit and environmental benefit have been obtained. However,it was found that so far the fishmen living along the river still have a significantly higher level of hair mercury than those living in a non-mercury polluted area,and 1.92% of them have a level of hair mercury exceeding the national diagnostic standards.They were found to be mainly distributed along the first Songhuajiang reaches of the river downstream Sanchahekou.Extremely less number of cases for the fishmen living along the second Songhuajiang reaches of the river were found to have a level of hair mercury exceeding the national diagnostic standards,and the causes for this were discussed also. |
