黄河下游鲁北平原地下水砷浓度空间变异特征与成因
Variation Characteristics and Causes of Arsenic Concentration in Shallow Groundwater of Northern Shandong Plain in the Lower Reaches of the Yellow River
摘要
Abstract
Based on the inorganic analysis of 1092 groundwater samples collected from 2006 to 2009 in Yellow River Plain and using the method of geo-statistics, this paper discussed the spatial variation and pollution of arsenic in shallow groundwater under the influence of human activities in this region. 26.65% of the samples exceeded the Drinking Water Standard in arsenic concentration, and the area surpassing the set standard accounted for 17.3% of the total area. The degree of dispersion of shallow groundwater was high and the coefficient of variation was over 100%. The spatial distribution of arsenic was anisotropic. The relationship between arsenic distribution and groundwater flow was not close, and the native condition and impact of pollution sources seem to be the main reasons. 7%of shallow groundwater samples suffered from arsenic pollution from human activity, and 18% of the arsenic polluted samples were caused by livestock breeding farms. The detection rate and exceeding rate of samples from livestock breeding farms was 2 times that of the whole study area. The arsenic pollution source included the animal waste from the scattered livestock breeding farms, the application of arsenic-bearing pesticides, and the discharge of industrial wastewater.关键词
