Concentrations of metals were determined in four species of anchovy (Coilia sp.) from the Yangtze River, Taihu Lake, and Hongze Lake in Jiangsu Province, China. Concentrations of Cr in anchovy fish muscle ranged from 2.6 × 10(-2) to 5.0 mg/kg ww, and Coilia nasus taihuensis in Jiaoshan, Taihu Lake contained the highest concentrations of Cr, which was almost 111-fold higher than the mean value a...

As part of an ongoing study, the water quality of the Susquehanna River between Otsego Lake and its junction with Oaks Creek was monitored during the summer of 1997. This monitoring program is designed to determine the assimilative capacity of the Susquehanna River below the point of discharge of the Village Sewage Treatment Plant. The study helps to detect point sources of pollution. The water...

Heavy metal (Pb, Zn, Cu, Cr, Ni, Mn and Cd) concentrations were investigated for the first time in core sediments of the Municipal Lake of Yaounde, Cameroon. The area under study receives domestic raw sewage from surrounding populated neighborhoods through River Mingoa, main tributary of the lake. Other activities like automobile service stations, garages, non operational effluent treatment sta...

An innovative approach was developed to reveal phosphorus (P) transport and redistribution in large and complex river networks in the Lake Taihu basin by establishing the relations between sediment P spatial distribution and P sorption behavior on particles with different grain size, sorted by hydrodynamics. The sediment P fractionation composition changed greatly across the basin, where 69% co...

Repetitive element-polymerase chain reaction (REP-PCR) DNA fingerprinting and library-based microbial source tracking (MST) methods were utilized to investigate the potential sources of Escherichia coli pollution in recreational waters of southeastern Lake Huron. In addition to traditional sources such as humans, agriculture, and wildlife, environmentally persistent E. coli isolates were includ...

The U.S. Department of Interior has identified the Truckee River basin as highly likely for potential water supply conflict in the future. A critical water supply to the Truckee River is outflow from Lake Tahoe, and surface and groundwater contributions from the Martis Valley hydrographic area. This paper highlights the development of an integrated surface water and groundwater model, GSFLOW, i...

A population of Echinorhynchus baeri Kostylew, 1928 with 18-24 rows of 8-10 proboscis hooks each and long fusiform eggs measuring 95-110 × 18-22 μm collected from Salmo trutta (Salmonidae) in a branch of the Murat River in Turkey is described and specimens are designated as neotype. Specimens of two similar populations of E. baeri (E. baeri Kostylew, 1928 and E. sevani Dinnik, 1932) were previo...

BENFER, N.P., KING, B.A. and LEMCKERT, C.J., 2007. Salinity observations in a subtropical estuarine system on the Gold Coast, Australia. Journal of Coastal Research, SI 50 (Proceedings of the 9th International Coastal Symposium), 646 – 651. Gold Coast, Australia, ISSN 0749.0208 Saltwater Creek and Coombabah Creek are branches of the Coomera River estuary situated within the subtropical Gold Coa...

Microplastics are a source of environmental pollution resulting from degradation of plastic products and spillage of resin pellets. We report the amounts of microplastics from various sites of Lake Ontario and evaluate their potential for preservation in the sediment record. A total of 4635 pellets were sampled from the Humber Bay shoreline on three sampling dates. Pellet colours were similar t...
