“…where K P refers to dermal permeability coefficient of pollutant; t event represents event duration; ED d , EV, and EF d represent dermal contact exposure duration, the event frequency, and dermal contact exposure frequency, respectively; GIABS is the fraction of chemical absorbed in gastrointestinal tract; SA refers to skin surface area. The values of parameters were obtained from the references and shown in Table S2 ( Akhbarizadeh et al, 2016;IRIS, 2018;Ranjbar Jafarabadi et al, 2017;Sarria-Villa et al, 2016;USEPA, 2004;USEPA, 2016).

Coastal groundwater quality significantly affects the regional sustainable development, due to the water resource shortage in coastal zone. Current studies on coastal groundwater have mainly focused on saline water intrusion and over-extraction. Information on the heavy metal pollution of coastal groundwater with salinization trend is limited. This study investigated heavy metals in groundwater from a typical coastal region with intensive anthropogenic activities and saline water intrusion. The southwestern coastal plains of the study area showed significant groundwater salinization trend. Heavy metals in the coastal groundwater mainly originated from anthropogenic activities and groundwater salinization according to principal component analysis. Relative high concentrations of As, Co, Cr, Cu, Fe, Mn, and Ni occurred in the southwestern coast of the study area with high TDS level, indicating that the concentrations of these heavy metals in shallow aquifer of the study area might be influenced by the groundwater salinization. Average concentrations of heavy metals in groundwater of the study area ranged from 0.03 (Cd) to 686.92 (Fe) μg/L. Fe was the dominant heavy metal in groundwater with the maximal concentration of 2333.76 μg/L and exceeding-standard rate reaching 98.23%. Approximately 13.27% of sampling sites showed moderate or higher heavy metal pollution of groundwater based on heavy metal pollution index. Heavy metals in groundwater exerted low ecological risks. Elements Fe, Ni, and As were the main contributors for ecological risks. Cancer risks of heavy metals for both adults and children were high at all sampling sites. Non-cancer risks for adults and children were unacceptable at 4.42% and 17.70% of sampling sites, respectively. The

“…Therefore, this study used cancer and non-cancer risks to evaluate the potential health risks of antibiotics. Cancer risk (CR) and hazard quotient (HQ) of individual pollutant through dermal contact were calculated using the following equations (Akhbarizadeh et al, 2016;Sarria-Villa et al, 2016;USEPA, 2004):…”

Information on ecological and health risks posed by antibiotics in coastal waters at continental or national scale is limited although antibiotics have continuously entered the natural environments due to extensive usage for human beings and animals. This study collected coastal water samples along nearly 18,000 km of coastline of China to investigate the distribution, possible sources, and potential ecological-health risks of antibiotics. Only 7 out of 13 target antibiotics were detected in coastal water samples. Total concentrations of antibiotics ranged from 389 to 3302.3 ng/L. Norfloxacin (NFC), roxithromycin (RTM), and ciprofloxacin (CFC) were the most frequently detected antibiotics, with the maximal concentrations of 1990, 1230, and 109 ng/L, respectively. Antibiotics in coastal waters might be affected by three possible factors including veterinary-drug sources, anthropogenic sources, and mixed sources. Detected NFC and sulfamethoxazole (SMX) exerted high ecological risks in the short and long terms. CFC posed moderate short-term risks but insignificant long-term risks for aquatic organisms. RTM exerted low short-term risks while it posed moderate risks in the long term. Antibiotics exerted very low cancer risks and negligible non-cancer risks for both adults and children at all sampling sites. Health risks for children posed by antibiotics were generally higher than those for adults. Antibiotics in coastal waters of China still need effective control due to potential ecological-health risks they pose.

“…The method used for factor analysis in this study is a commonly used one for the determination of the source of polycyclic aromatic hydrocarbons (Akhbarizadeh et al, 2016;Ma et al, 2016). Fifteen types of PAHs were extracted for two common factors of eigenvalues greater than 1, and the cumulative variance contribution rate was as high as 92.20%.…”

The objectives of this study were to examine the association between PM 2.5 -associated polycyclic aromatic hydrocarbons (PAHs) and their meteorological factors, and the relationship between PM 2.5 -associated PAH concentrations and temperature, air pressure and air humidity. Data collected by Center for Disease Control (CDC) in Nanchang urban areas during the fall and winter seasons of 2014-2015 were analyzed by using high performance liquid chromatography (HPLC). Our study showed that the PM 2.5 mass concentration had a mean of 0.088 µg m -3. Our results showed that the total concentration of PAHs in Nanchang was 22.54 ng m -3 (RSD: 8.50) and 15 different types of PAHs examined in this study all exceeded the China national standard. Multiple regression analysis revealed that the daily average concentration of total PAH was significantly associated with the temperature and daily minimum humidity (p < 0.05), but not daily wind speed and rainfall. Principal component analysis and characteristic ratio study indicated that the source of PAHs in PM 2.5 were mainly from vehicle exhaust and coal and gas combustion in Nanchang.
