Dustfall Heavy Metal Pollution During Winter in North China

Abstract

In order to study heavy metal pollution in dustfall during Winter in North China, forty-four dustfall samples were collected in North China Region from November 2013 to March 2014. Then forty trace elements content were measured for each sample by inductively coupled plasma-mass spectrometry. Finally, the contamination characteristics of the main heavy metals were studied through a multi-method analysis, including variability analysis, Pearson correlation analysis and principal component analysis. Results showed that the relative contents of cadmium (Cd), zinc (Zn), copper (Cu), bismuth (Bi), lead (Pb) exceeded the standards stipulated in Chinese soil elements background values by amazing 4.9 times. In this study, conclusions were drawn that dustfall heavy metal pollution in the region was mainly caused by transport pollution, metallurgy industrial pollution, coal pollution and steel industrial pollution.

Concentration Levels, Pollution Characteristics and Potential Ecological Risk of Dust Heavy Metals in the Metropolitan Area of Beijing, China

“…In Formula (1), is on behalf of the target element i’s concentration; is the concentration of the selected reference element n ; and are ratios between research element concentration and reference element concentration respectively in environmental samples and soil background [ 28 ]. With a small variation coefficient, Tb was chosen as the reference element in this study, whose content distribution in the atmospheric dust of Beijing is relatively stable [ 29 , 30 ]. The background value of each element is derived from the average concentration of the corresponding element in the soil of Beijing.…”

Assessment of the Ecotoxicity of Pollution by Potentially Toxic Elements by Biological Indicators of Haplic Chernozem of Southern Russia (Rostov region)

“…According to (GOST 1983 ; Quing, 2015 ), chemical elements (metals, metalloids, and nonmetals) are ranged into hazard classes with respect to human health. However, results of previous studies (Crommentuijn et al, 1997 ; Kolesnikov et al, 2010 , Vodyanitskii, 2012 ; Xiong et al, 2015 ) have shown that many elements do not correspond to the specified hazard classes (degrees) in terms of the effects on soil state and it is advisable to develop their own hazard classes for soil ecosystems. In recent years, the problem of assessing PTE (metals, non-metals, and metalloids) by hazard classes has undergone some changes.…”

“…Soil pollution with bismuth affects the state of ecosystems and human health (Wei et al, 2011 ; Yang and Sun, 2011 ; Unai Cortada et al 2018 ; Li et al, 2014 ; Xiong et al, 2015 ). Ore deposits containing Bi increase its background content in the soil cover up to 300 ppm (Yurgenson & Gorban 2017 ).…”

Biogeochemical assessment of coastal urban soils and ecological safety

“…However, the soils in the river beds flowing through a large industrial center are also subject to the equally active negative influence of anthropogenesis. The anthropogenic impact of urban activities on the environment, as a rule, is considered within the framework of the environmental approach, which identifies various types and sources of pollution: atmospheric air, water, soil, plants [5]. Studies of coastal soils of water bodies, in river estuaries, in zones of overflow, floodplain soils 1010 (2022) 012107 IOP Publishing doi:10.1088/1755-1315/1010/1/012107 2 are very few in number, although it is they that make it possible to reveal the intensity of migration of chemical elements both due to surface runoff and air fallouts.…”
