To explore the role of hair、plasma、erythrocyte lead in evaluation of occupational exposure level. Content of hair,plasma,erythrocyte lead in lead exposure group and control group were determined by atomic absorption spectropmotometer.The results were statistically treated with SAS software. Polluted lead on hair surface can be effectively eliminated by 0.25 mol/L HCl.Between lead exposure group and control group,there is no difference in plasma lead,but there is statistically significant difference in hair...

Using STELLA software, a model was constructed to study the influences of drawing different types of water to Sanyang wetland on TP concentration of water body, and simulated the change of TP in water before and after the exterior pollution sources were cut off through the model. Results showed that when the exterior and interior pollution sources coexisted, the current TP concentration would keep on rising, the water quality continued worsening, and even if better quality of water, such as Ⅲ, Ⅳ and Ⅴ types of water quality, were introduced into the wetland, the TP would continue increasing, up to 890.57 mg·m-3, 891.06 mg·m-3 and 891.57 mg·m-3 after 230, 260 and 282 days later, respectively, and exceeded the present TP concentration. If exterior pollution sources were cut off, the increasing rate of TP in water slowed down, but the TP in water maintained rising since the interior pollution sources, the current water continued deteriorating in 270 days later, with the TP being 1008.31mg·m-3. The TP would be 890.67 mg·m-3, 892.00 mg·m-3 and 890.59 mg·m-3 when Ⅴ, Ⅳ and Ⅲ type of water were introduced 300 days, 318 days and 342 days later, exceeding the current concentration. These results implied that cutting off the exterior pollution sources by drawing water to the wetland only played a limited role to solve eutrophication problem in Sanyang wetland.

采用STELLA软件,构建了三垟湿地水体TP随时间变化的模型并通过此模型模拟了消除外源污染前后引水水体TP的变化。结果表明,内外污染源共存时,当前水体TP会进一步增加,水质继续恶化,即便引入较好的水质,TP含量也将继续增加,富营养化状况得不到彻底解决;若消除外源污染,对当前水体TP含量的迅速增加起到一定的减缓作用,但因内源污染的作用,引入不同的水质,TP仍会增加。因此,仅通过引水来解决三垟湿地水体富营养化问题的作用是有限的。
