为了解砷冶炼厂废渣污染环境的范围、程度以及暴露人群的砷负荷,探讨环境神污染对人群健康的影响,我们于1987年9月到该厂进行了调查。 调查内容和方法 在两个废渣堆放处各取废渣混合样1公斤,再以废渣堆为起点,在顺废渣迳流下方50、100、300米处分别布点取土壤、禾苗样品各1公斤(湿重)备检。对废渣迳流下方稻田内的两口井水也分别采样备检。 以废渣迳流下方300米内农田(地)为污染区,以饮用废渣迳流下方150～250米稻
In order to understand the scope and extent of arsenic smelter waste pollution of the environment, as well as exposure to arsenic load, to explore the impact of environmental pollution on the health of the population, we went to the factory in September 1987 were investigated. Investigation contents and methods In the two waste dumps, each mixed with 1 kg of waste residue, and then the waste pile as a starting point, 50,100,300 meters along the waste residue Shu stream were distributed to take soil, seedlings samples 1 kg (wet Heavy) for inspection. The two well water in the paddy field below the waste stream is separately sampled for inspection. Take the farmland (ground) within 300 meters below the slug flow as the pollution area, and drink 150 to 250 meters rice
