Abstract
A monitoring survey of antifouling biocides was conducted in the Harima Nada Sea and Osaka Bay of the Seto Inland Sea, Japan to assess contamination by organotin (OT) compounds and alternative biocides. The concentrations of tributyltin (TBT) compounds in surface water ranged from 1.0 to 2.8 ng/L, and the detected TBT concentrations in the bottom water layer were higher than those in the surface water. The concentrations of TBT compounds in sediment samples ranged from 2.0 to 28 ng/g dry weight (dw), respectively. The concentrations of alternative biocides in the water and sediment were lower than those before the banning of TBT by the International Maritime Organization (IMO). Although triphenyltin (TPT) compounds were not detected in water samples, TPT compounds were detected in the range of < 0.1–2700 ng/g dw in sediment samples. Their concentrations in the water samples were as follows: diuron, < 1–53 ng/L; Sea-Nine 211, < 1–1.8 ng/L; Irgarol 1051, < 1–4.0 ng/L; dichlofluanid, < 1–343 ng/L; and chlorothalonil, < 1–1 ng/L, and the ranges of these alternative compounds in sediment samples were diuron, 32–488 ng/g dw; Sea-Nine 211, 47–591 ng/g dw; Irgarol, 33–128 ng/g dw; dichlofluanid, 67–8038 ng/g dw; and chlorothalonil, 31–2975 ng/g dw. Thus, the OTs and alternative biocides have still been detected in water and sediment samples from closed sea areas.
期刊介绍:
Archives of Environmental Contamination and Toxicology provides a place for the publication of timely, detailed, and definitive scientific studies pertaining to the source, transport, fate and / or effects of contaminants in the environment. The journal will consider submissions dealing with new analytical and toxicological techniques that advance our understanding of the source, transport, fate and / or effects of contaminants in the environment. AECT will now consider mini-reviews (where length including references is less than 5,000 words), which highlight case studies, a geographic topic of interest, or a timely subject of debate. AECT will also consider Special Issues on subjects of broad interest. The journal strongly encourages authors to ensure that their submission places a strong emphasis on ecosystem processes; submissions limited to technical aspects of such areas as toxicity testing for single chemicals, wastewater effluent characterization, human occupation exposure, or agricultural phytotoxicity are unlikely to be considered.
