Polycyclic Aromatic Hydrocarbons in Three Varieties of Fish From Kuwait Bay

Historic and contemporary contamination in the marine environment of Kuwait: An overview

“…A small number of studies attempted to evaluate the human health risks posed by the consumption of fish and crustaceans. Results would suggest that PAHs (Saeed et al, 1995;Beg et al, 2009) pose little risk, while As in lobsters and Hg in fish (Al-Majed and Preston, 2000) have been reported to exceed human consumption limits. It is encouraging to see a growing number of studies attempting to link toxicological endpoints with the chemical contamination of Kuwait's marine contamination (Randolph et al, 1998;Beg et al, 2003a;Stentiford et al, 2014;Smith et al, this issue;Al-Zaidan et al, this issue).…”

“…Concentrations of PAHs have been measured across both summer and winter months in the whole body of three fish species native to Kuwait waters (Beg et al, 2009). Seasonal differences in concentrations were observed both within and between the species examined, with the profile of high and low molecular weight PAHs indicating they were mainly from a petrogenic origin (Beg et al, 2009). Attempts have been made to estimate the risk PAH contamination of seafood caught from Kuwaiti waters pose to human consumers (Al-Yakoob et al, 1994;Saeed et al, 1995).…”

“…In the same study concentrations of TPH (2.3-2.7 lg g À1 dw TPH equiv, ROPME oil) and P PAH 2.9-3.5 ng g À1 dw reported in Hamoor (Epinephelus coioides) were considered unexceptional and representative of uncontaminated fish by the authors. Concentrations of PAHs have been measured across both summer and winter months in the whole body of three fish species native to Kuwait waters (Beg et al, 2009). Seasonal differences in concentrations were observed both within and between the species examined, with the profile of high and low molecular weight PAHs indicating they were mainly from a petrogenic origin (Beg et al, 2009).…”

“…Market-based sampling of shrimp and fish from a range of trophic and ecological levels was matched to consumption figures for the key species examined (Saeed et al, 1995). Similar to the work of Beg et al (2009) the profile of detected PAHs indicated petrogenic sources of contamination with naphthalene (2-156 ng g À1 ) and phenanthrene (5-89 ng g À1 ) in particular the most abundant. Matching these data with consumer consumptions habits indicated that concentrations detected posed little if any public health concerns (Saeed et al, 1995).…”

Metallothionein, oxidative stress and trace metals in gills and liver of demersal and pelagic fish species from Kuwaits’ marine area

“…However, the toxicity of sediment tested against solid phase Microtox test was higher for sediment from Kuwait Bay area (Beg and Al-Ghadban, 2003). There was a seasonal impact on the accumulation of PAHs (Beg et al, 2009) and the levels of heat shock proteins in fish from the two areas (Beg et al, 2010). The impact of season and reproductive cycle is well established on the accumulation of metals and metallothionein levels (Schiedek et al, 2006;Podrug and Raspor, 2009;Marijic and Raspor, 2010).…”
