In 1979, a preliminary survey conducted in a district located near a copper smelter revealed elevated lead levels in the blood of some children and in the soil. In 1989, a more comprehensive study was undertaken to determine the blood lead contamination of the children and to determine soil contamination patterns. A method was devised for evaluating soil contamination by equally weighting each area of a predetermined grid. Three zones of contamination provided indirect evidence that suggested a contribution of diffuse emissions, compared with stack emissions, and assisted in the determination of priorities for remedial action.
1979年，在一座铜冶炼厂附近的一个地区进行的初步调查显示，一些儿童的血液和土壤中的铅含量升高。1989年，开展了一项更全面的研究，以确定儿童血液中的铅污染情况，并确定土壤污染模式。设计了一种方法，通过对预定网格的每个区域进行同等加权来评估土壤污染。三个污染区域提供了间接证据，表明与烟囱排放相比，存在扩散排放的影响，并有助于确定补救行动的优先次序。
