China is the world’s largest consumer of fertilizer, with fertilizer plants widely distributed throughout the country. With the removal and closing of fertilizer factories in recent years, pollutant surveys and risk assessments (human health risks) for these sites have become increasingly necessary. However, there has been little research on contaminated fertilizer factory sites. This study aimed to characterize the distribution of pollutants, assess the health risk of the site, and calculate the remediation area and volume in a typical fertilizer plant site in North China. A total of 443 samples were collected in 2019; they indicated that the study site had high concentrations of copper (Cu), ammonia-nitrogen (NH3-N), total petroleum hydrocarbons (TPH), and fluoride at maximum ratios (the ratio of the highest value of all test data for a particular pollutant to the standard value of the pollutant) of 3.30, 2.55, 19.69, and 1.10, respectively. The health risk assessment results suggested that some hazard quotients exceeded the threshold safe level (>1 established by environmental regulations). The risk control values of soil were 2000 mg/g (Cu), 826 mg/g (TPH), and 1549 mg/g (NH3-N), and the total remediation soil volume was 72860.71 m3. The results provided basic information on soil pollution control and environmental management in a contaminated fertilizer plant site.

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.

In the present study, concentrations of heavy metals (Cu, Zn, Pb, Cd) in soil and wheat grains of the agricultural areas around Baiyin, a non-ferrous metals mining and smelting base, were detected. Meanwhile, the potential health risk of the heavy metals to adult males, adult females and children was estimated using non-carcinogenic health risk assessment model: Hazard Quotient (HQ) and Hazard Index (HI). The results showed that only the level of Cd in all soil samples exceeded the permissible limit of the environmental quality standard for soil, and its average level surpassed the standard value by 4 times. In wheat grains, the levels of Pb and Cd were 50 times and 8 times of the limited values of hygienic standard for grain respectively, while Cu and Zn concentrations did not surpass the standard value. The potential health risk due to single heavy metal for all the three investigated populations followed the sequence of HQPb＞HQCd＞HQCu＞HQZn＞1 (assumed the local inhabitants wholly food on wheats), suggesting that each of the four heavy metals were making negative effect on population health, of which the situation of Pb and Cd should be paid more attention due to their significant adverse effect. The total potential health risk due to the four heavy metals followed the sequence of HIchildren＞HImales＞HIfemales＞1 (assumed that the health risk due to the four heavy metals is additive), suggesting that the heavy metals were producing adverse effect on population health, and were especially hazardous for children. According to the research results, the government is suggested to strictly control the quality of irrigation water and remove the heavy metals from agricultural soil in order to ensure the safety of foodcrop production and local inhabitants.

Abstract Groundwater samples of Ile-Ife, Osun State, Nigeria were investigated for their organochlorine pesticides (OCPs) levels. Probable sources of the OCPs and health risks associated with their consumption along with the water were determined in order to establish the potability of the groundwater samples. Quantitative determination of the OCPs was carried out by Gas Chromatography coupled with Electron Capture Detector (GC-ECD) after liquid-liquid extraction with dichloromethane (DCM). Results indicated that all the analyzed OCPs except p,p'-dichlorodiphenylethane were detected with high concentrations in the groundwater. Heptachlor (14.60±3.60 µg L-1) and methoxychlor (12.60±2.20 µg L-1) showed dominant concentrations that were higher than 0.02 ng L-1 maximum residue levels (MRLs) recommended by the European Union. Levels of the OCPs in the samples followed the decreasing trend: cyclodienes > diclorophehylethanes > chlorinated cyclohexanes, while the predominant source of the analyzed pesticides could be ascribed to aerial transportation from fresh applications in homes within the community. The carcinogenic health risk assessment also revealed consistent higher values of HQ and CR in children as opposed to adults, indicating that children are the more vulnerable population to the analyzed environmental contaminants.
