Metals and metalloids in PM 10 in Nandan County, Guangxi, China, and the health risks posed
Intense mining, smelting, and tailing activities of polymetallic ore deposits have affected the environment in Nandan County, Guangxi, China. Samples of particulates with aerodynamic diameters low or equal 10 μm (PM ) were collected in Nandan County to investigate the concentrations of and health ri...

| description | Intense mining, smelting, and tailing activities of polymetallic ore deposits have affected the environment in Nandan County, Guangxi, China. Samples of particulates with aerodynamic diameters low or equal 10 μm (PM
) were collected in Nandan County to investigate the concentrations of and health risks posed by 17 metals and metalloids in the PM
. The metal and metalloid concentrations were lower than those found in other industrial cities. The mean Cr concentration was 7.48 ng/m
. Significant higher metal and metalloid concentrations were found in PM
from mining areas (Dachang and Chehe) than from the control area (Liuzhai) (p 1). The carcinogenic risks posed by Cd, Ni, and Pb were negligible at all sites, while As, Co, and Cr posed potential carcinogenic risks to the residents. |

from mining areas (Dachang and Chehe) than from the control area (Liuzhai) (p < 0.05). Principal component analysis indicated that the main sources of Ba, Co, Cr, Fe, K, Mg, Mo, Na, and Sr were resuspension of the soil produced through mineral erosion, the main sources of As, Cd, Cu, Pb, Sb, and Zn were smelting and mining activities, and the main source of Ni was fossil fuel combustion. Higher non-carcinogenic and carcinogenic risks were posed in Dachang and Chehe than in Liuzhai. The non-carcinogenic risks posed to adults and children by individual metals and metalloids in PM
at all the sites were low, but the non-carcinogenic risks posed to children by all the metals and metalloids together exceeded the safe level (i.e., risk value > 1). The carcinogenic risks posed by Cd, Ni, and Pb were negligible at all sites, while As, Co, and Cr posed potential carcinogenic risks to the residents.</description><identifier>EISSN: 1573-2983</identifier><identifier>DOI: 10.1007/s10653-018-0083-2</identifier><identifier>PMID: 29549472</identifier><language>eng</language><publisher>Netherlands</publisher><ispartof>Environmental geochemistry and health, 2018-10, Vol.40 (5), p.2071</ispartof><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>314,776,780,27901,27902</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/29549472$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Guo, Guanghui</creatorcontrib><creatorcontrib>Song, Bo</creatorcontrib><creatorcontrib>Xia, Deshang</creatorcontrib><creatorcontrib>Yang, Zijie</creatorcontrib><creatorcontrib>Wang, Fopeng</creatorcontrib><title>Metals and metalloids in PM 10 in Nandan County, Guangxi, China, and the health risks posed</title><title>Environmental geochemistry and health</title><addtitle>Environ Geochem Health</addtitle><description>Intense mining, smelting, and tailing activities of polymetallic ore deposits have affected the environment in Nandan County, Guangxi, China.
