Pollution characteristics and source apportionment of heavy metal(loid)s in soil and groundwater of a retired industrial park

Heavy metal(loid)s(HMs)pollution has become a common and complex problem in industrial parks due to rapid industrialization and urbanization.Here,soil and groundwater were sampled from a retired industrial park to investigate the pollution characteristics of HMs.Results show that Ni,Pb,Cr,Zn,Cd,and Cu were the typical HMs in the soil.Source analysis with the positive matrix factorization model indicates that HMs in the topsoil stemmed from industrial activities,traffic emission,and natural source,and the groundwater HMs originated from industrial activities,groundwater-soil interaction,groundwater-rock interaction,and atmosphere deposition.The sequential extraction of soil HMs reveals that As and Hg were mainly distributed in the residue fraction,while Ni,Pb,Cr,Zn,Cd,and Cu mainly existed in the mobile fraction.Most HMs either in the total concentration or in the bioavailable fraction preferred to retain in soil as indicated by their high soil-water partitioning coefficients(K_(d)),and the K_(d) values were correlated with soil pH,groundwater redox potential,and dissolved oxygen.The relative stable soil-groundwater circumstance and the low active fraction contents limited the vertical migration of soil HMs and their release to groundwater.These findings increase our knowledge about HMs pollution characteristics of traditional industrial parks and provide a protocol for HMs pollution scrutinizing in large zones.

An novel identification method of the environmental risk sources for surfacewater pollution accidents in chemical industrial parks

The chemical industry is a major source of various pollution accidents. Improving the management level of risk sources for pollution accidents has become an urgentdemand for most industrialized countries. In pollution accidents, the released chemicals harm the receptors to some extentdepending on their sensitivity or susceptibility. Therefore, identifying the potential risk sources from such a large number of chemical enterprises has become pressingly urgent. Based on the simulation of thewhole accident process, a novel and expandable identification method for risk sources causingwater pollution accidents is presented. The newlydeveloped approach, by analyzing and stimulating thewhole process of a pollution accident between sources and receptors, can be applied to identify risk sources, especially on the nationwide scale. Three major types of losses, such as social, economic and ecological losses,were normalized, analyzed and used for overall consequence modeling. A specific case study area, located in a chemical industry park （CIP） along the Yangtze River in Jiangsu Province, China,was selected to test the potential of the identification method. The results showed that therewere four risk sources for pollution accidents in this CIP. Aniline leakage in the HS Chemical Plantwould lead to the most serious impact on the surroundingwater environment. This potential accidentwould severelydamage the ecosystem up to3.8 kmdownstream of Yangtze River, and lead to pollution over adistance stretching to 73.7 kmdownstream. The proposed method is easily extended to the nationwide identification of potential risk sources.

基于多米诺效应的南京化工园区洪水Natech风险研究

以南京化工园区为对象,在“浸没型”洪水背景下,开展了基于多米诺效应的洪水Natech风险评估,结果表明,在“浸没型”洪水背景下,园区内甲醇储罐泄漏的概率最大,为3.89×10^(-3)。以甲醇储罐T51和T52为对象,评估了甲醇泄漏引发的水污染和蒸气云爆炸风险,结果表明:在甲醇泄漏速率为0.62 kg/s、甲醇质量浓度边界为0.20 kg/m^(3)的条件下,泄漏1.00 h后甲醇最远可扩散至下游383.51 m处;以10%(φ)的泄漏甲醇参与蒸气云爆炸进行计算,距离储罐周边140.02 m范围内的人群将100%致死。考虑多米诺效应,当储罐T51和T52发生蒸气云爆炸时,周边T31~T50、T53和T54储罐所接收到的爆炸超压均超过失效阈值(0.03 MPa),进一步造成污染物泄漏和蒸气云爆炸事故;污染物泄漏1.00 h后,将扩散至下游约400 m处;蒸气云爆炸事故100%致死范围将扩大至377.78 m。
