Exposure Pathways

Based on the methods of health-based risk assessment of contaminated sites and the analysis of heavy metal pollution in a simple landfill sludge site, we assessed the integrated human health risk of soil contamination. It is concluded that the main pollutant is heavy metal. There are three exposure pathways identified: workers inside the site, residents working on the farmland and those living down of the site. This assessment indicates that workers would suffer non-carcinogenic impacts with total multi-pathways non-carcinogenic hazard index for heavy metal being 0.397,and the carcinogenic impacts being 2.2×10-7. The residents working on the farmland would suffer non-carcinogenic impacts with total multi-pathways non-carcinogenic hazard index for heavy metal being 0.788, and the carcinogenic impacts being 4.5×10-7. The residents living downslope of the site would suffer non-carcinogenic impacts with total multi-pathways non-carcinogenic hazard index for heavy metal being 6.22 for adults and 1.25 for children, and the carcinogenic impacts being 3.4×10-6 for adult and 7.5×10-7 for children. Non-carcinogenic index of the site and farmland areas are less than 1, while the non-carcinogenic health risk is negligible. Their carcinogenic index is less than 10-6, and the cancer health risk is small. The adults living downslope of the site have a greater risk of non-carcinogenic and carcinogenic risk. The children have non-carcinogenic risk and dont have carcinogenic risk.

Heavy metals are released into the water system through various natural processes and anthropogenic activities, thus indirectly or directly endangering human health. The distribution, source, water quality and health risk assessment of dissolved heavy metals (V, Mn, Fe, Co, Ni, Zn, As, Mo, Sb) in major rivers in Wuhan were analyzed by correlation analysis (CA), principal component analysis (PCA), heavy metal pollution index (HPI), hazard index (HI) and carcinogenic risk (CR). The results showed that the spatial variability of heavy metal contents was pronounced. PCA and CA results indicated that natural sources controlled Mn, Fe, Co, Ni and Mo, and industrial emissions were the dominant factor for V, Zn and Sb, while As was mainly from the mixed input of urban and agricultural activities. According to the heavy metal pollution index (HPI, ranging from 23.74 to 184.0) analysis, it should be noted that As and Sb contribute most of the HPI values. The health risk assessment using HI and CR showed that V and Sb might have a potential non-carcinogenic risk and As might have a potential carcinogenic risk to adults and children in the study area (CR value exceeded target risk 10−4). At the same time, it was worth noting that As might have a potential non-carcinogenic risk for children around QLR (HI value exceeded the threshold value 1). The secular variation of As and Sb should be monitor in high-risk areas. The results of this study can provide important data for improving water resources management efficiency and heavy metal pollution prevention in Wuhan.

Abstract The objective of the study was to determine concentration of metals in sidewalk dust collected in close vicinity to heavily congested roads in Poland in order to assess non-carcinogenic and carcinogenic health risk for both children and adults associated with the ingestion, dermal contact and inhalation of sidewalk dust. Results revealed that sidewalk dust from Warsaw, Krakow, Wroclaw and Opole is heavily contaminated especially with Sb, Se, Cd, Cu, Zn, Pb, considered as indicators of traffic emission. Hazardous indices determined for different exposure pathways indicated that the greatest health risk for both children and adults is associated with the ingestion of sidewalk dust. Carcinogenic risk associated with the ingestion of sidewalk dust by children, calculated for As, Cd, Ni and Pb exceeded safe level of 1 × 10−4 in all cities except for Warsaw. Non-carcinogenic risk of ingestion for children was two orders of magnitude higher than dermal risk and four to five orders of magnitude higher than risk of inhalation. Non-carcinogenic risk associated with the ingestion of sidewalk dust by adults is comparable with dermal contact risk and five orders of magnitude higher when inhalation risk.
