270 citations
••

264 citations
••
TL;DR: In this paper, the authors considered rivers, lakes and their basins as a model to investigate global water environmental issues and developed a new method of numerical water quality estimation for organic river pollution.
134 citations
••
TL;DR: In this paper, lead isotopes ratios have been determined in suspended matter and water samples collected from major rivers and estuaries in France to assess their present level of Pb pollution.
99 citations
••
TL;DR: In this article, field observations have shown that the removal of a substantial proportion of the riverine influx of dissolved trace metals is a consistent feature of the very low salinity, high turbidity zone of the Tamar Estuary.
99 citations
••
TL;DR: In this paper, a 2 3 + 1 factorial design was used to study adsorption of butyltin compounds under simulated estuarine conditions, including artificial seawater and its dilutions (salinity 5-35 g kg −1 ), pH (6.2-8.2), and hydrous iron oxide concentration (10-1000 mg l −1 ).
95 citations
••
TL;DR: In this paper, the distribution of the potentially ecotoxic heavy metals Cd, Pb and Cu between the dissolved and the particulate matter phase has been studied in the Oosterscheldt and Westerschelft estuaries, The Netherlands, in five missions during the spring, summer and winter of 1979-1980.
92 citations
••
TL;DR: In this article, a radiochemical neutron activation analysis of water, soil, pine needle and algae samples collected in the vicinity of the nuclear fuel reprocessing plant in Tokaimura/Ibaraki, and from other areas of Japan, were determined by radiochemical neutromagnetic activation analysis.
88 citations
••
TL;DR: Polar bear livers from six Management Zones in the western and central Canadian Arctic were analysed for 22 elements and no statistically significant effect of age, sex or geographical location was found for any of the elements, except Cd, Hg and Se, for which age and geographical location effects were found.
81 citations
••
TL;DR: In areas of gross sludge contamination, a marine geophysical survey technique can be used to delineate the area affected and this provides a rapid cost-effective method for large areas.
••
TL;DR: In this article, the authors explored the relationship between behavioral intention (BI) and market values through three field experiments and concluded that contingent valuation is not a good substitute for market behaviors, and that willingness to pay is a much better indicator of what hunters actually paid to buy a permit.
••
TL;DR: In this paper, fly ash samples from 11 coal-fired power plants and a refuse incinerator in the UK were analyzed for total arsenic, cadmium, lead and selenium Enrichment Factor (EF) values calculated with respect to crustal abundance (EFcrust).
••
TL;DR: In this article, the type of industrial location constraint criteria that might be imposed and the required in situ and remotely sensed data can be placed in a geographic information system (GIS) to model and identify candidate waste sites.
••
TL;DR: In this article, the elemental compositions of house dust, street dust and soil have been determined for 26 elements on material collected in Christchurch, New Zealand, and the elements Hf, Th, Sc, Sm, Ce, La, Mn, Na, K, V, Al and Fe may be considered to be soil-based and contribute about 45-50% to house dust and 87% to street dust, while the elements which are enriched (>3 times) in the dusts relative to the levels found in local soils, are Br, Cu, Cl, Pb
••
TL;DR: In this paper, the reactivity of soil humic acids toward added Cu2+ and Fe3+ ions, the type of complexes formed and their water- and HCl-stability have been studied by infrared and electron spin resonance spectroscopy.
••
TL;DR: In this paper, the authors compared the levels of lead, zinc, and cadmium in floodplain soils in the catchment of the River Hamps and the River Manifold in North Staffordshire.
••
TL;DR: Flatfish, mainly in the form of plaice, and crustacea were found to be the main source of organic arsenic compounds, which gave rise to elevated concentrations of arsenic in the urine of human subjects from two cities in Sweden.
••
TL;DR: The eider duck, although a short-distance migrating bird whose diet is composed mainly of mussels and crustaceans, and which lives along a great part of the Swedish coastline, is suggested as a biomonitor of cadmium for the aquatic environment.
••
TL;DR: Sources de la pollution, teneurs en Europe dans diverses zones, Cycle and voies de contamination de l'homme, et Etude de cas.
••
TL;DR: Dentine appears to be the best material to use to estimate lead, particularly in relation to the integrated lead intake of a person.
••
TL;DR: In this article, the leachability of chlorinated hydrocarbons, chlorophenols and light aromatic compounds was studied for three typical Norwegian soils, and good correlations between soil adsorption constants (Koc) and water solubility were obtained.
••
TL;DR: The inverse relationship between hard water and cardiovascular disease will be discussed, and specific data relating hardness and Mg and Ca content of potable waters to specific geographic regions of the U.S.A. will be presented.
••
TL;DR: In this article, the alteration of marble and limestone surfaces of the facade of Reggio Emilia Cathedral has been studied, and the impact of air pollution seems to prevail over natural weathering mechanisms, including biological processes.
••
TL;DR: PGI tested electrophoretically showed for all five species a statistically significant higher proportion of heterozygotes among the dead animals than among the survivors in the range of concentration tested, which seems to have been established by natural selection.
••
TL;DR: The conclusion of this evaluation is, that the Danish articles do not prove that occupational exposure to organic solvents produces a presenile demens, and the indications that it does are very slender.
••
TL;DR: Evaluated by the SCE test, seal diet, smoking, living district and blood Hg and Cd concentrations all contribute to mutagenicity in Greenlandic Eskimos, with seal diet as the most important of the factors examined.
••
TL;DR: The methodology of critical pathway analysis successfully employed to assess the impact of the nuclear industry has been applied to evaluate the stable metal pollution in the Paraiba do sul River (PSR), Brazil as discussed by the authors.
••
TL;DR: In this article, the spatial and seasonal distribution of the surface values were analyzed in order to observe differences in photosynthetic activity and chlorophyll a concentrations within a particular area, and with that the degree of eutrophication.
