Occurrence and Distribution of Polycyclic Aromatic Hydrocarbons (PAHs) in Bolgoda and Beira Lakes, Sri Lanka

Abstract: The pollution of polycyclic aromatic hydrocarbons (PAHs) has been widely used to assess the potential impact of anthropogenic activities on aquatic environments because their occurrence in water is closely tied to urban activities. Many PAHs possess mutagenic and carcinogenic properties (Menzie et al. 1992). PAH distribution and toxic potentials have therefore been the focus of numerous studies in waterways including the Great Lakes (USEPA Report 1994), Yanisei Bay (Dahle et al., 2003), and the Fraser River ba… Show more

“…The elevated hepatic EROD activities in Nile tilapia collected from the Lake irrespective of the sampling period indicate that the Lake is contaminated with CYP1A inducing chemicals such as PAHs and/or PCBs. In a recent study, petrogenic and pyrogenic PAHs have been detected in the water (colloid bound) and sediments collected from different sampling sites of this Lake (Pathiratne et al 2007). PAHs may have contributed partly or fully for the observed high induction levels of hepatic EROD in the fish collected from this Lake.…”

“…Recent studies have reported the trophic status, gross pollution and PAH pollution in Lake Beira (Kamaladasa and Jayatunga 2007;Pathiratne et al 2007). This is the first study which focused on assessing the exposure and biological effects of pollutants present in this hyper eutrophic tropical Lake using a suite of biomarkers of the resident fish.…”

“…Pathiratne et al (2007) reported low levels of total PAH contamination in water samples taken from Sri Lanka's Beira Lake (46-112 ng/L) and Bolgoda Lake (40-127 ng/L). In the Xijiang River in Guangdong, South China, Deng et al (2006) found that the total concentrations of 15 PAHs ranged from 21.7 to 138 ng/L in water and from 40.9 to 665 μg/L in suspended particle matter.…”

“…They calibrated using published data on various wastewater systems and they projected different rehabilitation and maintenance scenarios and identified the most cost effective approach to rehabilitate and maintain a wastewater system. A high-performance liquid chromatography (HPLC) was used to assess the potential impact of anthropogenic activities on aquatic environments in Sri Lanka, where due to the lack of municipal sewer systems substantial quantities of domestic sewage and untreated wastewaters are discharged directly into the lake [7]. They revealed that the fish populations residing in this lake is under threat due to the pollution stress that is mainly associated to the recurrent exposure to PAHs and toxigenic microcystis blooms in the Lake.…”
