Situation of soil pollution today by heavy metals in Japan was measured, and its characteristics was analyzed. Efficiency of some measurement methods of heavy metal soil pollution was also studied. The following conclusions were obtained.1. Hydrochloric acid extraction method was better than some other methods for investigating local characteristics of soil pollution.2. New sampling method, which collected ground soil dividing a sampling column into two layers, 2.5cm upper soil and 2.5cm lower soil, and new analyzing method, which analyzed the difference of the two layer soil, was proposed. This method was efficient for identifying the effect of the chemical fallout, and able to sampling the time of pollution approximately.3. Field survey in the central Japan area showed the great effect of metal mining industry and the existence of heavier pollution in several tens years ago than today in Pacific coast.4. Indices of human activity were proposed. Multiple linear regression analysis with the indices as independent variables and heavy metal concentration as dependant variables showed that Cr and Co were affected by the index of population density, that Sn seemed to have relationship to the distance from incineration plants, and that Zn and Cd was typically affected by mining industries.5. Health risks of direct intakes of soil were analyzed. It was shown that Pb and As had larger proportion in health risks than other heavy metals.6. 1N hydrochloric acid extraction method was good alternative to PBET, Physiologically Based Extraction Test.

测定了日本土壤重金属污染现状，分析了日本土壤重金属污染特征。同时对几种土壤重金属污染检测方法的有效性进行了研究。得出以下结论：1.盐酸浸提法较其他方法更适合于调查土壤污染的局部特征.提出了一种新的采样方法，即把地面土壤分成两层，上层2.5cm，下层2.5cm，并对两层土壤的差异进行分析。该方法能有效地识别化学沉降物的影响，并能近似采样污染时间.在日本中部地区的实地调查显示，金属采矿业的巨大影响，以及在几十年前比今天更严重的污染存在于太平洋沿岸.提出了人类活动指数。以各指标为自变量，重金属浓度为因变量的多元线性回归分析表明，Cr和Co受人口密度指标的影响，Sn似乎与距离垃圾焚烧厂的距离有关，Zn和Cd则典型地受采矿业的影响.分析了土壤直接摄入的健康风险。结果表明，铅和砷在健康风险中所占比例较大. 1N盐酸浸提法是PBET（生理浸提试验）的良好替代方法。
