River Sediment Sampling and Environment Quality Standards: A Case Study of the Ravensbourne River
… and poses significant risks not only to river quality but also to aquatic and benthic organisms. At present in the UK, there are no mandatory sediment quality standards. This is partly due to insufficient toxicity data but also due to problems with identification of appropriate sediment …

A study of potentially toxic elements in the Forth and Clyde Canal, Scotland, UK
… Waterways in 1992 but higher than relevant environmental quality standards, as was the Hg concentration (0.589 - 9.19 mg/kg) determined using CVAFS. The concentration of Fe was relatively constant, but an urban/rural divide was evident in the concentrations of the other analytes, indicting …

Investigation into an adsorption and electrochemical regeneration process for the treatment of two trace level pesticides
… Framework Directive – aimed at achieving good environmental quality of surface waters at the catchment level - has a series of environmental quality standards that must not be exceeded for a wide range of water pollutants, including pesticides and other organic contaminants. To meet these …

An extension of the recreational carrying capacity concept : a procedure for recreation resource allocation in the planning of natural landsapes
… of values, the uncertainties of predicting environmental impacts and the influence of the subjective values and preferences of decision makers. This leads to the conclusion that a framework is required to guide the recreation opportunity allocation decision process. This framework is to be …

Diffuse Minewater Pollution: Quantification and Risk Assessment in the Tamar Catchment
… represent a significant threat to surface water quality via generation of acid mine waters. Currently the River Tamar fails environmental quality standards (EQS) established under the Water Framework Directive (2000/60/EC) for dissolved Cu (x ̅ = 0.19 ± 0.05 μmol L-1) and Zn (x ̅ = 0.19 ± 0.06 …

Copper and Zinc Speciation in the Tamar Estuary
… Cu and Zn, two metals that possess revised environmental quality standards (EQS) which now account for potential metal bioavailability. Dissolved metal concentrations in the < 0.4 and < 0.2 μm filter fractions of samples from the Tamar Estuary were determined during seasonal transects made …

TOWARD A BETTER CLEANING AND SELECTIVITY IN ELECTROANALYSIS: TIO2-BASED SENSORS AND ENANTIOSELECTIVE MATERIALS
In the latest years the concern on environmental issues has grown dramatically. One of the major problems of environmental chemistry are emerging contaminants (ECs), which are not commonly monitored in the environment. They can cause undesirable effects on ecosystems and human health. This group of …

Phosphorus speciation, agronomic performance and soil nutrient testing for waste recovered fertiliser use in Northern Irish soil
… in the United Kingdom (UK) are failing to meet Environmental Quality Standards (EQS) for fresh waters under the European Union (EU) Water Framework Directive. In Northern Ireland (NI), agronomic and environmental targets for soil P are based on measurements of sodium bicarbonate extractable-P …
