Responses of magnetic properties to heavy metals pollution recorded by sediments of Nanchang City reach of Ganjiang River, East China.
In this paper, sediment samples from the HT and QS profiles of the Ganjiang River are selected to represent the river reach that does not enter and entered the Nanchang City urban area, respectively. Environmental magnetism, granulometry, and heavy metal of these samples were analyzed to assess the relationship between magnetic properties and heavy metal. The results showed that the mean χ value of QS profile is 20.32 × 10-8m3/kg, which is higher than that in HT profile (3.80 × 10-8m3/kg), indicating the higher magnetic mineral concentrations. The relatively higher S-100mT, S-300mT, and lower χARM/χ, χARM/SIRM values of QS profile suggest the lower imperfect antiferromagnetic mineral proportion and the coarser magnetic minerals grains, respectively. The heavy metals (i.e., As, Cd, Sb, Cr, Cu, Zn, Pb) concentration of QS profile is markedly higher than that of HT profile. The PLI of QS profile ranges from 0.5 to 3.33, higher than that in HT profile (0.22 to 2.02), revealing the more serious pollution in urban areas and would be attributed to human activities. In QS and HT profile, the concentration-dependent magnetic parameters (e.g., χ, SIRM, HIRM) are significantly positively correlated with heavy metals and PLI. We also found that with a similar particle size composition, the sediment samples with higher pollution levels exhibit higher χ, SIRM, S-100mT, S-300mT, and lower χARM/χ, χARM/SIRM values, indicating the response of magnetic properties to heavy metal pollution. Magnetic parameters can be used as a heavy metal pollution indicator in the Ganjiang River.
期刊介绍：
Environmental Geochemistry and Health publishes original research papers and review papers across the broad field of environmental geochemistry. Environmental geochemistry and health establishes and explains links between the natural or disturbed chemical composition of the earth’s surface and the health of plants, animals and people.
Beneficial elements regulate or promote enzymatic and hormonal activity whereas other elements may be toxic. Bedrock geochemistry controls the composition of soil and hence that of water and vegetation. Environmental issues, such as pollution, arising from the extraction and use of mineral resources, are discussed. The effects of contaminants introduced into the earth’s geochemical systems are examined. Geochemical surveys of soil, water and plants show how major and trace elements are distributed geographically. Associated epidemiological studies reveal the possibility of causal links between the natural or disturbed geochemical environment and disease. Experimental research illuminates the nature or consequences of natural or disturbed geochemical processes.
The journal particularly welcomes novel research linking environmental geochemistry and health issues on such topics as: heavy metals (including mercury), persistent organic pollutants (POPs), and mixed chemicals emitted through human activities, such as uncontrolled recycling of electronic-waste; waste recycling; surface-atmospheric interaction processes (natural and anthropogenic emissions, vertical transport, deposition, and physical-chemical interaction) of gases and aerosols; phytoremediation/restoration of contaminated sites; food contamination and safety; environmental effects of medicines; effects and toxicity of mixed pollutants; speciation of heavy metals/metalloids; effects of mining; disturbed geochemistry from human behavior, natural or man-made hazards; particle and nanoparticle toxicology; risk and the vulnerability of populations, etc.
