Distribution, source identification, and historical trends of organic micropollutants in coastal sediment in Jakarta Bay, Indonesia

Non-Target Screening Method for the Identification of Persistent and Emerging Organic Contaminants in Seafood and Sediment from Jakarta Bay

“…The concentrations in sediment were higher than those from the same location (Rinawati et al, 2012) or from Asian coastal (in Mumbai coast India and in Manila Bay) reported by Isobe et al (2004). Howev er, no prev i ous reports about LABs concentrations in fish and shrimp species sampled in Indonesian coastal waters or in other Asian regions are available, but the concentration is higher than that in white croaker (Genyonemus lineatus) collected near a large wastewater outfall in southern California (Phillips et al, 2001).…”

Utility of soil linear alkylbenzenes to assess regional anthropogenic influences with special reference to atmospheric transport

“…They were also substantially lower than those in river sediments from Zhujiang River, Xijiang River and Dongjiang River of the PRD (Luo et al, 2008;Zhang et al, 2012), Sumidagawa River and Tamagawa River in Japan (Takada and Ishiwatari, 1987), and Arakawa River (Takada et al, 1992), lake sediments from Chaohu Lake , and coastal sediments from the coastal zones of Guangdong Province (Liu et al, 2013), Jakarta Bay (Rinawati et al, 2012), Santa Monica Bay (Venkatesan et al, 2010), Victoria Harbor (Hong et al, 1995), Barcelona Harbor (Díez et al, 2006), Tokyo Bay (Takada et al, 1992), South and Southeast Asia (Isobe et al, 2004), and Southern California Bight (Macías-Zamora and Ramírez-Alvarez, 2004). They were slightly lower than those in nearshore sediments from the Pearl River Estuary and the northern South China Sea (Luo et al, 2008) and Admiralty Bay (Martins et al, 2012).…”

“…To this end, additional evidence can be obtained from linear alkylbenzenes (LABs), which are uniquely associated with the production of linear alkylbenzene sulfonates (LASs) (Eganhouse et al, 1983), one of the most widely used anionic detergents and surfactants. Linear alkylbenzenes can be discharged into the environment as residues (1-3%) of commercial detergents (Hartmann et al, 2000;Eganhouse and Sherblom, 2001;Heim et al, 2004;Isobe et al, 2004), and in fact have been detected in various environmental matrices from different regions worldwide (Eganhouse et al, 1983;Takada and Ishiwatari, 1987;Takada et al, 1992;Isobe et al, 2004;Medeiros and Bícego, 2004;Martins et al, 2010Martins et al, , 2012Venkatesan et al, 2010;Rinawati et al, 2012). For example, previous studies presented evidence for direct discharge of untreated wastewater, which may have exerted strong impacts on aquatic systems of the PRD and the adjacent South China Sea (Luo et al, 2008;Ni et al, 2008;Zhang et al, 2012).…”

Tracking anthropogenic influences on the continental shelf of China with sedimentary linear alkylbenzenes (LABs)

“…For example, RLAB concentrations in the present study were comparable to those in sediments from Xijiang River, the PRE and the northern SCS (Luo et al, 2008), Southern California Bight (Macías-Zamora and Ramírez-Alvarez, 2004), Wash and Humber estuaries (Raymundo and Preston, 1992), Santos Bay and Estuary (Medeiros and Bícego, 2004), Santos Bay (Martins et al, 2008), and Admiralty Bay (Martins et al, 2012). However, they were substantially lower than those in sewage sludge (Takada et al, 1994;Luo et al, 2008), suspended particles in river water from the PRD , Sumidagawa River and Tamagawa River (Takada and Ishiwatari, 1987), as well as sediments from Dongguan , Zhujiang River (Luo et al, 2008), Dongjiang River (Luo et al, 2008), Arakawa River (Takada et al, 1992), Sumidagawa River and Tamagawa River (Takada and Ishiwatari, 1987), Chaohu Lake , the coastal zones of Guangdong Province (Liu et al, 2013a), Victoria Harbor (Hong et al, 1995), Tokyo Bay (Takada et al, 1992), Jakarta Bay (Rinawati et al, 2012), Santa Monica Bay (Venkatesan et al, 2010), and South and Southern Asia (Isobe et al, 2004). The greater RLAB concentrations in the sediments of the Pearl River Delta (PRD; 1.5-2330 ng/g) and Chaohu Lake (19-5720 ng/g) were attributed to direct discharge of untreated or partially treated domestic wastewater and proximity to input sources (Luo et al, 2008;Wang et al, 2012;Zhang et al, 2012).…”

“…Besides, LABs were suggested to be toxic (Gledhill et al, 1991;Johnson et al, 2007), where the acute toxicity of LABs to Caenorhabditis elegans in soil was reported as a lethal concentration of 1550 ng/g to cause 1% fatality in 24 h, with the 95% confidence limits in the range of 80-3360 ng/g (Johnson et al, 2007). Because of these attributes, LABs are good indicators of human activities uniquely associated with sewage contamination in different regions around the world (Eganhouse et al, 1983;Takada et al, 1992;Isobe et al, 2004;Medeiros and Bícego, 2004;Luo et al, 2008;Martins et al, 2008;Ni et al, 2009;Venkatesan et al, 2010;Martins et al, 2012;Rinawati et al, 2012).…”
