Source identification and hazardous risk delineation of heavy metal contamination in Yanqi basin, northwest China

Assessment of concentration and toxicological (Cancer) risk of lead, cadmium and chromium in tobacco products commonly available in Bangladesh

“…The concentration of metals in industry produced fertilizers and pesticides used for tobacco cultivation are the primary contributors to pollution of agricultural soil and plants [41]. The metal content is enhanced by tobacco processing [[42], [43], [44]] and eventually, the heavy metals enter the human body via inhalation and consumption [[45], [46], [47]]. …”

Ambient air metallic pollutant study at HAF areas during 2013–2014

“…Principal component 2 consisted of Cd and Pb and originated from industrial, agricultural and transportation influences. Our study found that Pb and Zn were a large part in principal components 1 and 3 and were influenced by a combination of geologic background and human activity Atmospheric Research 158-159 (2015) 107-121 (Mamat et al, 2014). The major heavy metals in waste are Zn, Cr, Cu, Pb, Ni, Hg, and Cd, etc. in the incineration process.…”

Sources and geochemical background of potentially toxic metals in surface sediments from the Zhejiang coastal mud area of the East China Sea

“…Currently, source identification of potentially toxic metals is mostly conducted by calculating the enrichment factor to classify natural and anthropogenic origins (Xu et al, 2014;Luo et al, 2015), or by means of multivariate analysis to group natural and key anthropogenic input types (Yuan et al, 2004;Mamat et al, 2014;Luo et al, 2015;Soltani et al, 2015).…”
