Distribution of Polycyclic Aromatic Hydrocarbons in Edible Fish from Gomti River, India

Abstract

This study reports the levels and distribution patterns of selected polycyclic aromatic hydrocarbons (PAHs) in fish samples of the Gomti river, India, collected from three sites during the pre- and post-monsoon seasons of the years 2004-2005. In the fish muscles, SigmaPAHs ranged between 12.85 and 34.89 ng g(-1) wet wt (mean value: 23.98+/-6.70 ng g(-1)). Naphthalene was the most prevalent compound both in terms of detection as well as levels, while, benzo[k]fluoranthene, benzo(a)pyrene, and indeno(123-cd)pyrene + benzo(ghi)perylene could not be detected in any of the sample. Low-molecular weight PAHs were observed dominating over the high molecular weight PAHs.

Polycyclic Aromatic Hydrocarbons in Various Species of Fishes from Mumbai Harbour, India, and Their Dietary Intake Concentration to Human

“…Other species such as Otolithes ruber, Eleutheronema tetradactylum and Mystus seenghala detected relatively equal concentration, whereas the minimum concentration was detected in Sardinella longiceps. The total PAHs concentration reported in fish samples of the present study appears to be higher than the concentration reported in edible fishes (0.207-3.365 ppm) of the Gomti river, Lucknow, India [23]. The PAHs concentration detected in the fishes of present study is comparable with study reported in the muscles of the fish, from fish pound of the Pearl river delta (49.59 ng/g wet wt) [34] and lower than the levels in the Mai Po Marshes Nature Reserve of Hong Kong (497 ng/g wet wt.)…”

“…Certain groups of population may have higher risks from dietary exposure of PAHs than the general populations [16]. In India there are many studies on the presence of petroleum hydrocarbons in the Goa coastal water [17], north-west coastal water [18,19], fish and prawn from north west coast of India [20], bivalve in east coast of India [21], freshwater and fish [22,23], soil and sediment [24], and marine environment of Mumbai [25]. However, there is no information available concerning dietary intake of PAHs and their risk from fish consumption.…”

PAHs and PCBs accumulated by SPMD-based virtual organisms and feral fish in Three Gorges Reservoir, China

“…2001; Liang et al, 2007;Malik et al, 2008;Pointet and Milliet, 2000;Zhao et al, 2014). Relative higher concentrations of PAH congeners with lower octanol-water partition coefficients (Log Kow less than 5.0) in fish are due to their higher gill-water transfer efficiencies as suggested by Cheung et al (2007), while lower residues of compounds with higher molecular weight (HMW) and higher Kow (Log Kow larger than 5.0) might be mainly attributed to the enhanced biotransformation as well as decreased gut assimilation in fish (Liang et al, 2007).…”

Distribution of polycyclic aromatic hydrocarbons in water and bed sediments of the Gomti River, India

“…The results of our preliminary study showed that water and bed sediments of Gomti River are contaminated, and a detailed study is required so that the necessary actions could be taken. Recently, Malik et al (2008) reported contamination of fish from the Gomti River with PAHs. The present study reports the status of PAHs in the water and bed sediments of the Gomti River during the period of March 2004 to February 2006.…”
