Abstract Mining activities could induce severe heavy metal pollution in soil and surface water, which would consequently pose potential ecological environment risks and human health risks. In this research, total 82 agricultural soil samples and 34 water samples were collected from a special area that surrounding a lead-zinc mine. Pollution level, source apportionment, ecological and health risks of heavy metals were evaluated based on the concentrations of cadmium (Cd), chromium (Cr), copper (Cu), manganese (Mn), nickel (Ni), lead (Pb) and zinc (Zn). According to the results, Cd and Zn were obviously enriched metals in agricultural soil in the study area, meanwhile, the potential risks which calculated by geo-accumulation index were showed a high ecological risk due to high concentration of Cd found in local agricultural soil. Additionally, heavy metal sources analyzed by the PMF model could be classified into four categories: mining activity (Mn), parent material (Cr, Ni), atmospheric deposition caused by industrial and mining activities (Pb, Zn, Cd) and agricultural activities (Cu). Compared with the values specified by corresponding water quality standard, the heavy metals content in surface water were below these values except Cd, while the content of seven heavy metals in drinking water was within the safe limits. The bioavailability of Cd, Pb and Zn in soil were higher than other metals, and when the bioavailability of metals was consideration into health risk assessment, the total HI and TCR values were far below the accepted risk levels. Though human health risks were within the safe margin, the toxic hazards of heavy metals to residents and ecological should be taken into consideration.

Background. The rise in particulate matter (PM) concentrations is a serious problem for the environment. Heavy metals associated with PM10, PM2.5, and road dust adversely affect human health. Different methods have been used to assess heavy metal contamination in PM10, PM2.5, and road dust and source apportionment of these heavy metals. These assessment tools utilize pollution indices and health risk assessment models. Objectives. The present study evaluates the total mass and average concentrations of heavy metals in PM10, PM2.5, and road dust along selected road networks in Dhanbad, India, analyzes the source apportionment of heavy metals, and assesses associated human health risks. Methods. A total of 112 PM samples and 21 road dust samples were collected from six stations and one background site in Dhanbad, India from December 2015 to February 2016, and were analyzed for heavy metals (iron (Fe), lead (Pb), cadmium (Cd), nickel (Ni), copper (Cu), chromium (Cr), and zinc (Zn)) using atomic absorption spectrophotometry. Source apportionment was determined using principal component analysis. A health risk assessment of heavy metal concentrations in PM10, PM2.5, and road dust was also performed. Results. The average mass concentration was found to be 229.54±118.40 μg m−3 for PM10 and 129.73 ±61.74 μg m−3 for PM2.5. The average concentration of heavy metals was found to be higher in PM2.5 than PM10. The pollution load index value of PM10 and PM2.5 road dust was found to be in the deteriorating category. Vehicles were the major source of pollution. The non-carcinogenic effects on children and adults were found to be within acceptable limits. The heavy metals present in PM and road dust posed a health risk in the order of road dust> PM10> and PM2.5. Particulate matter posed higher health risks than road dust due to particle size. Conclusions. The mass concentration analysis indicates serious PM10 and PM2.5 contamination in the study area. Vehicle traffic was the major source of heavy metals in PM10, PM2.5, and road dust. In terms of non-carcinogenic risks posed by heavy metals in the present study, children were more affected than adults. The carcinogenic risk posed by the heavy metals was negligible.

The results of studies of the heavy metal background level in the natural environment ofthe Qaumarujuk and Agfardlikavså fjords, adjacent to the lead-zinc mine Sorte Engel (= Black Angel) near Mârmorilik (71°07'N, 51°16'W), have been briefly communicated by Bondam & Asmund (1974), Asmund (1975), Bohn (1975) and BoIlingberg (1975). FuHdetails of the analyticaI results of these surveys have been reported in Danish elsewhere. (Vandkvalitetsinstituttet 1972; Grønlands Fiskeriundersøgelser et al., 1974; GGU et al., 1975). Since then, renewed sampling has been carried out, both in February and August 1974, and in April and September 1975, in order to follw closely the environmental dissemination of some heavy metals in the fjord region, due to disposal of tailings from the flotation plant adjacent to Agfardlikavsåfjord (fig. 18). This short communication deals with the content of certain heavy metals of bottom sediments, biological tissues and samples of sea water in the fjord regime after full production started in October 1973.

The Mean

Sewage sludge and livestock (chicken, swine and cattle) manure samples were collected from the Yanmenguan Cattle Herbivorous Livestock Area to compare the potential ecological and human health risks caused by heavy metals contained in them. In this study, the Class II level of Quality Control of Imported Organic Fertilizers is selected as the limit standard value of heavy metals. Based on the mean content values, no heavy metal in cattle manure was higher than the limit standard value; the content of Cu in swine manure was higher than the limit of Cu; the content of Zn in sewage sludge, chicken manure and swine manure were all higher than the limit of Zn; and the content of Cr in sewage sludge and chicken manure were all higher than the limit of Cr. Results indicated that sewage sludge and livestock manure all had high contents of Zn, Cu and Cr. The mean pollution index (PI) suggested that Cu, Zn, As and Cr in sewage sludge and livestock manures all induced potential ecological risks. According to the mean Nemerow’s synthetic pollution index (PN) values, swine manure had the highest potential ecological risk for agricultural use. Daily exposure to Cu, Zn and Cr was higher than other heavy metals from sewage sludge and livestock manures, and heavy metal exposure was always higher for children than adults, with ingestion as the main pathway. Non-carcinogenic risk was caused mainly by Cu and Cr, based on the higher hazard quotient (HQ) values for adults and children. There was no non-carcinogenic risk for all people, except exposure of Cu from swine manure for children, which was 1.76 times higher than the threshold value of 1. According to the mean hazard index (HI) values, only swine manure had a non-carcinogenic risk for children. As the carcinogenic risk index (Risk) values were continuously greater for As than Cd, As had a higher carcinogenic risk than Cd. There was no carcinogenic risk for any single heavy metal, although As exposure from sewage sludge was found to have an inapparent carcinogenic risk for both adults and children. Regarding the RISK value, sewage sludge had an unacceptable carcinogenic risk for adults and children, and swine manure had an unacceptable risk for children only. In general, for both non-carcinogenic and carcinogenic risks, ingestion was the main pathway, and children were more sensitive than adults. Comparing the four kinds of organic waste, cattle manure was the safest for agricultural use in terms of ecological and human health risks. In multiple comparisons, swine manure was significantly different regarding potential ecological risk and non-carcinogenic risk, and sewage sludge was significantly different regarding carcinogenic risk.
