“…The injector was set from 50 C (0.1 min isothermal) to 250 C (200 C min À1 ) held for 10 min. MS was run in the electron concentrations between 3 and 7 (Mitra et al, 2019) or between 4 and 7 (Tang et al, 2020) indicated the possible source of technical HCHs, while the ratio <4 indicates the use of lindane. Cischlordane/trans-chlordane ratio is evaluated based on (Alam et al, 2014).…”

“…PAHs have been regarded as priority pollutants by both the US Environmental Protection Agency (EPA) and the European Union (EU) due to their carcinogenicity, mutagenicity, and toxicity on both ecosystem and human health 3 . PAHs are mainly emitted from anthropogenic activities such as coal combustion, industrial manufacturing, waste incineration, and power generations [4][5][6] . Anthropogenic PAHs can be released into all the environment 7 .…”

The spatial and temporal distribution of polycyclic aromatic hydrocarbons (PAHs) was investigated in sediments of Maba River, a major tributary of Beijiang River (South China). A total of 13 samples from Maba River and its tributary, Meihua River, were analyzed for 16 PAHs. The total concentration of 16 PAHs (ΣPAH) in high and low water period ranged between 47.61 to 25480.98 ng g−1, with a mean concentration of 4382.98 ng g−1, and 60.30 to 15956.62 ng g−1 with a mean concentration of 3664.32 ng g−1, respectively. Three-ring and four-ring PAHs were the dominant species. It was concluded that a pattern of pyrolytic input as a major source of PAHs in sediments through the molecular ratio method for the source identification, such as HMW/LMW PAHs, Flu/(Flu+Pyr), IcdP/(IcdP+BghiP) and BaA/(BaA+Chr). It is suggested that the pollution emission from the iron and steel plant might be the most important sources of PAHs into Maba River water system. The threat of PAHs contamination to biota of the river was assessed using effect range low (ERL) and effect range median (ERM) values, which suggested that PAHs in Maba River and its tributary had already caused ecological risks.

“…Five samples showed the Flu/ (Flu+Py) ratio within 0.4 and 0.5 (SS2, SS5, SS7, SS9, and SS23) which suggests the combustion of petroleum products as the source of these PAHs. It has been observed that sediment samples from the South 24 Parganas were contaminated with PAHs due to petroleum spills in the recent past (Mitra et al, [14] ). In contrast, PAHs sources in sediment samples from other districts were derived either from incomplete combustion of woods or from the local release of motor oil (vehicular emissions from incomplete combustion).…”

“…In India, several studies have investigated the spatial distribution of PAHs. For example Mitra et al [14] studied the surface sediments (0-5 cm) in the Hooghly River estuary in the Western Bengal basin. Anthropogenic activities resulted in the introduction of different point and non-point source PAHs in drinking water in the area.…”

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.
