“…BPA is thought to be decomposed relatively more easily than other organic matter contained in leachate since TOC was not decreased during the designated experimental period. The concentration of BPA was decreased to below one hundredth in 48 h, and is similar to that reported for actual leachate treatment facilities (Asakura et al, 2004(Asakura et al, , 2007.…”

“…In this study, the procedures in "The Interim Manual for Endocrine Disrupting Chemicals Examination" (WMS, 1998) were adopted. The procedures have been described by Asakura et al (2004) in more detail. In regard to coagulation and sedimentation treatment, EDCs in sediment obtained by filtration through glass fiber filter of 1.0 μm pore size were also determined according to the manual.…”

“…In Japan and other countries, bisphenol A (BPA) and diethylhexylphthalate (DEHP), which are regarded as endocrine-disrupting chemicals (EDCs), were detected at higher concentrations in leachate from municipal solid waste landfill sites than in surface water (Bauer et al, 1998;Robinson and Gronow, 1998;Yasuhara et al, 1999;Behnisch et al, 2001;Yamamoto et al, 2001;Fromme et al, 2002;Kjeldsen et al, 2002;Jonsson et al, 2003;Asakura et al, 2004). High concentrations of BPA and DEHP may have been flowing out from landfill sites as leachate for many decades (Asakura et al, 2003).…”

An experimental study of the behavior of endocrine-disrupting chemicals (EDCs) in leachate treatment processes (aeration, coagulation and sedimentation, activated carbon adsorption, and advanced oxidation) was conducted and removal efficiencies were evaluated. Among target EDCs, concentrations of BPA (1800 times), DBP (10 times), BBP (40 times), and DEHP (30 times) in leachate are more than ten times higher than those in surface water. BPA, DBP, and BBP can be treated by aeration and DEHP, by advanced oxidation processes. BPA could not be effectively removed by coagulation and sedimentation because most of BPA partitioned in the supernatant. DEHP could hardly be treated by aeration. The removal ratios of DEHP were approximately 50 to 70% if the generated sediment was removed completely. The removal ratios of DEHP in leachate of 100 m 3 /d with 100 kg of activated carbon were 50 to 70%, assuming a complete mixing model. The concentration of DEHP was decreased to below one tenth in 120 min by advanced oxidation processes.

“…In many landfill sites in industrialized countries, treatment facilities are installed and the environmental burden of these EDCs is reduced. High removal efficiency of BPA has been reported with aerobic treatment (99.3 -99.7%, Kawagoshi et al 2003;Asakura et al 2004) and with membrane bioreactors (95.3%, Wintgens et al 2003). However, because of high concentrations of BPA in raw leachates, even treated leachates showed higher BPA concentrations (0.11 -30 mg l ).…”

Plastics debris in the marine environment, including resin pellets, fragments and microscopic plastic fragments, contain organic contaminants, including polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons, petroleum hydrocarbons, organochlorine pesticides (2,2 0 -bis(p-chlorophenyl)-1,1,1-trichloroethane, hexachlorinated hexanes), polybrominated diphenylethers, alkylphenols and bisphenol A, at concentrations from sub ng g -1 to mg g -1. Some of these compounds are added during plastics manufacture, while others adsorb from the surrounding seawater. Concentrations of hydrophobic contaminants adsorbed on plastics showed distinct spatial variations reflecting global pollution patterns. Model calculations and experimental observations consistently show that polyethylene accumulates more organic contaminants than other plastics such as polypropylene and polyvinyl chloride.

“…Sep-Pak Ò Plus PS-2 cartridges have been reported and proved to adsorb almost all of organic micropollutants in water (Ishii et al, 2000) and have been widely applied to recover agricultural chemicals (Tanabe et al, 2000;Sudo et al, 2002;Tanabe and Kawata, 2004), endocrinedisruptors (Asakura et al, 2004), brominated flame retardants (Hasegawa and Suzuki, 2005), phenols (Hanada et al, 2002), microcystins (Kondo et al, 2000) and food preservatives (Okayama et al, 1998) from complex environmental water samples. During each elution, air was first injected manually into the cartridge with a syringe to drive out the space water.…”

a b s t r a c tIn order to integratedly evaluate the biological safety as a water quality index, an assessment method based on three toxicity tests (algae growth inhibition, daphnia immobilization and larval fish toxicity) was developed. In this study, the developed method was used to screen, evaluate and rank the biological safety of small rivers near agricultural, industrial and residential areas. Twenty-seven representative water samples were collected from the Kaname River watershed and the Hinata River watershed in Kanagawa Prefecture, Japan. The results indicated that (1) the biological safety of water from the Hinata River ranked much higher than those from the Suzu River and the Shibuta River due to less human activities, (2) the biological safety from outlets of paddy fields ranked much worse than those from point source discharges of toxic pollutants, (3) the use of pesticides significantly affected the water quality of nearby small rivers and ditches during the pesticide application season, (4) the effects of different kinds of pesticides could successfully be classified using one toxicity test component of the bioassay battery, and (5) there was no significant quantitative relationship between the toxicity and dissolved organic carbon (DOC) for the studied water samples. The toxicities of water samples in this study were in agreement with the concentrations of pesticides determined with chemical methods by other researchers, which demonstrated that the developed assessment method was reliable to screen site contaminated with organic chemicals for priority management.
