Spatial contamination and health risks of heavy metal(loid)s in surface soils from a petrochemical complex in the north-eastern region of Algeria

Abstract: The spatial distribution patterns, origins and environmental and health risks of metal trace elements (As, Cd, Co, Cr, Cu, Ni, Pb, Zn) have been analyzed through the spiking and the analysis of 84 soils sampled in the region of Arzew (Algeria). This city gathers one of the biggest petroleum harbors of Algeria and gathers in the same platform several industries, coexisting with residential and agricultural areas. The mean concentration of all the metals studied exceed their corresponding backgrounds levels and/… Show more

“…The results of correlation coefficient and PCA indicate that As may have a different origin from the other elements. Arsenic in the soil may come from human activities including the extraction of industrial gases (refineries, petrochemicals and power plants), mining, agricultural pesticides, and atmospheric dust deposition and resuspension(Boudia et al 2019).…”

“…Environmental heterogeneity due to geographic isolation might account for high arsenic levels in individual soils [ 66 , 67 ]. Besides, Cr contamination might come from the metallurgical industry [ 68 ]. Hg pollution was generally believed to be mainly due to human activities.…”

“…At present, most researches focus on the use of PCR-DGGE, fluorescence quantitative PCR and other biotechnologies combined with traditional microbiological methods to study the microbial and molecular ecological changes in heavy metal-contaminated soils under field experimental conditions, and to obtain soil microbial structure and functional composition under heavy metal pollution, providing a strong experimental basis for the restoration of heavy metal soil ecosystems [7][8]. Soil organic matter can control soil water content and water availability, and soil organic matter, as a routine measurement index, can be used to measure soil water retention and its availability [9].…”
