In order to investigate the contamination levels of trace metals, surface water samples were collected from six regions along Yangtze River in Nanjing Section. The concentrations of trace metals (As, B, Ba, Be, Cd, Cr, Cu, Fe, Pb, Li, Mn, Mo, Ni, Sb, Se, Sn, Sr, V and Zn) were determined using inductively coupled plasma-atomic emission spectrometry (ICP-AES). Total concentrations of the metals in the water samples ranged from 825.1 to 950.4 microg/L. The result was compared with international water quality guidelines. Seven metals levels were above the permissible limit as prescribed by guidelines. A preliminary risk assessment was then carried out to determine the human health risk via calculating Hazard Quotient and carcinogenic risk of the metals. Hazard Quotients of all metals were lower than unity, except As. The carcinogenic risk of As and Cd was higher than 10(-6), suggesting that those two metals have potential adverse effects on local residents.

“…In addition, the normal and extreme exposures can be used to evaluate the durations of PAH exposure, which are 7-24 years for adults and 2-6 years for children, respectively. Virtual safety is indicated when ILCR≤10 −4 , while a potentially high risk is indicated when ILCR≥10 −4 (Liao and Chiang 2006). The ILCR is suggested to be described as (Peng et al 2011 …”

Polycyclic aromatic hydrocarbons (PAHs) in rural soils of Dongjiang River Basin: occurrence, source apportionment, and potential human health risk

Purpose A comprehensive study was conducted to investigate the presence of polycyclic aromatic hydrocarbons (PAHs) in Dongjiang River Basin (DRB) soils and to evaluate their sources and ecological and health risk. In addition, factors affecting the distribution and fate of PAHs in the soils such as emission density, soil organic matter, degradation, etc. were studied. Materials and methods Surface soil (0-20 cm) samples from 30 sampling sites in the rural areas of DRB were collected and analyzed for 17 polycyclic aromatic hydrocarbons (16 EPA priority PAHs and perylene). Positive matrix factorization model was used to investigate the source apportionment of these PAHs, and an incremental lifetime cancer risk (ILCR) was used to estimate the integrated lifetime risks of exposure to soil-borne PAHs through direct ingestion, dermal contact, and inhalation collectively. Results and discussion The total PAH concentrations in the rural soils in DRB range from 23.5 to 231 μg/kg with a mean concentration of 116 μg/kg. The predominant PAHs in the rural soils were naphthalene, fluoranthene, phenanthrene, and benzo(b)fluoranthene. Cluster analysis was performed to classify the soil PAHs into three clusters, which could be indicative of the soil PAHs with different origins and different properties. Source apportionment results showed that coal, biomass, oil, commercial creosotes, and vehicle contributed 24 %, 24 %, 17 %, 17 %, and 18 % of the total soil PAH burden, respectively. The ILCR results indicated that exposure to these soil-borne PAHs through direct ingestion, dermal contact, and inhalation collectively produces some risk. Conclusions PAHs in the soils of the DRB will produce long-term influences on rivers and oceans via soil erosion and river transport. Therefore, PAHs in rural soils of DRB have potential impacts on the water supply and human health risk.

“…In regulatory terms, an ILCR of 10 -6 or less denotes virtual safety and an ILCR of greater than 10 -4 denotes potentially high risk [11]. Under calculated exposures, the estimated ILCRs for both adult and child are greater than 10 -4 .…”

The Meric-Ergene Basin, located on the north-western part of Turkey, begins with the Istanbul provincial border in the east and covers the border area with Bulgaria and Greece borders in the west. The industry developed at a rapid race, especially in the last fifty years, despite the importance of agriculture in the basin. In the study, 15 types of Polychlorinated Biphenils (PCBs) were determined in 4 regions of in an intense industrialized area, industrial+residential area, an agricultural area and a background area in total of 12 points, in 2014-2015, representing 4 seasons, in soil, lichen, pine needles and bulk samples, in the basin. In the study, spatial and seasonal changes in PCBs concentrations were set forth and "Incremental Lifetime Cancer Risk" were conducted. According to the results, increasing PCB values were observed in industrial areas and in soil samples. Generally heavier PCB species more abundant in the sampling area. PCB concentrations reached the highest values for all matrixes in the 2014 Spring and 2015 winter. According to the results of ILCR study, "Cancer Increase Rate" due to the PCB concentration was found to be over 10 -4 and cancer risk assessment studies are needed in the area.
