“…It has been reported that coral reefs are more common in areas with low PAHs content. T. Yang et al (2019) observed good linear correlations between PAH contents in seawater and sediments. However, Xiang et al (2018) reported a poor correlation between the biota-sediment accumulation factor and hydrophobicity, indicating that PAHs in corals possibly bioaccumulate from seawater.…”

In this study, we collected gas, particulate, and surface water‐dissolved phase samples from 16 sites in the South China Sea from March 21 to April 12, 2018. Thereafter, all the samples were analyzed for the air‐water exchange and source apportionment of polycyclic aromatic hydrocarbons (PAHs). Thus, it was observed that the overall PAH concentrations in the water and gas phases were 8.0 ± 5.5 ng/L and 41.3 ± 24.7 ng/m3, respectively. Back trajectory simulation showed that the air masses in the South China Sea primarily originated from mainland China during the heating period, and air‐water exchange analysis showed net deposition from air to water, with fluxes ranging from −5.53 to −89.72 ng/m2/d. Further, the logarithmic gas‐particle partitioning coefficient (logKp) of the PAHs regressed linearly with the logarithmic subcooled liquid vapor pressure (log P0 L), with an average slope of −0.3 ± 0.13.

“…Dried and homogenized 5 g of sediment was extracted with a mixture of dichloromethane and n-hexane (9:1 v/v). A Dionex® Accelerated Solvent Extractor 300 was used by programming it for three extraction cycles at 1000 psi and 100°C [19,20] followed by solid-phase extraction (SPE) using 6 mL C18 SPE glass cartridges, pre-rinsed with methanol and dichloromethane [21] .…”

Groundwater-sourced drinking water quality in South Asia, specifically India, is extremely stressed, mostly from the presence of many pervasive and geogenic pollutants. The presence and behavior of anthropogenic pollutants like polycyclic aromatic hydrocarbons (PAHs) are poorly investigated on a regional or basin-wide scale. The present study provides one of the first documentation of the presence and behavior of PAH in the aquifer sediments in the Ganges river basin. Lower and medium molecular weight PAHs e.g., naphthalene, phenanthrene, and fluoranthene were detected in 79, 36 and 13% of samples (n=25). The PAH level in groundwater was approximately five times lower than river water. The sorption behaviour of PAHs were studied in experiments in presence/absence of organic carbon and by simulating advective transport of low to medium molecular weight PAHs e.g., naphthalene, phenanthrene and fluoranthene in aquifer sediments collected from agricultural, peri-urban and urban areas. Naphthalene and phenanthrene adsorbed on quartz and kaolinite, but not on clay minerals like kaolinite. Fluoranthene adsorbed more favourably on kaolinite. Numerical modeling of the advective transport of PAHs in aquifers suggest up to 25 times faster movement of pollutants from irrigation-induced pumping, indicating the strong control of hydraulics on the spatial distribution of PAHs in sub-surface.

“…These elements do not play a key role in the growth and development of organisms. Heavy metals accumulations in the human body at certain levels will cause changes in various physiological functions of the human body and will eventually show the three pathogenic effects of "carcinogenesis", "teratogenesis" and "mutagenicity" 5 , 6 . It is becoming increasingly important to examine the ecological risks that are caused by heavy metals to the ecological environment and the health risks to the human body.…”

Enrichment of heavy metals in urban soils has become a major regional environmental risk. At present, research on the soil heavy metals in cities lacks risk spatial correlation analyses between different heavy metals, and there is a relative lack of assessments of the ecological and health risks. We selected Wuxi, a typical developed city of eastern China, collected and tested the contents of heavy metals in the urban soils of Wuxi in May 2020. Combined with Pb isotope analysis, ecological and health risk assessment, we found that the high heavy metal concentrations in Wuxi are mainly located in the central and western regions, and that the changes in spatial fluctuation are relatively small. The Pb isotopes in the urban soils of Wuxi are distributed in areas, such as those are related to coal combustion, automobile exhaust and urban garbage, indicating that the heavy metals in the urban soils of Wuxi are affected by human activities such as coal combustion and automobile exhaust. The average value of the potential ecological risk index of soil heavy metal Cd is 80.3 (the threshold: 40), which represents a high-risk state. Whether adults or children, the risk of soil heavy metals via ingestion is much higher than that through skin exposure. High health risk values are present in the central area of Wuxi and decrease in a ring-shaped pattern, which is similar to the population distribution of Wuxi and greatly increases the potential risk from soil heavy metals, which should be given close attention. We should develop and use clean energy to replace petroleum fossil fuels, especially in densely populated areas. This study provides technical support for the prevention and control of urban heavy metal pollution.
