This method statement provides guidance on the use of the metal bioavailability assessment tool (M-BAT) for practitioners involved in monitoring, assessment and classification using the new EQSbioavailable that have been developed for a number of metals under the Water F
The Final Recommendations on Environmental Standards following phase 3 of the review have been published (November 2013). This report includes zinc standards.
Setting appropriate environmental standards for metals is particularly challenging because the proportion of metal in the water environment that is bound up in forms that do not pose a risk of toxic effects on water animals and plants varies.
The UK Technical Advisory Group (UKTAG) has commissioned a programme of work to derive Environmental Quality Standards (EQSs) for substances falling under Annex VIII of the Water Framework Directive (WFD).
The assessment of compliance of surface waters with environmental quality standards (EQSs) for metals has to deal with a number of issues that do not apply to other substances.
A Manganese Bioavailability Tool has been developed that simplifies the integrated Biotic Ligand Model but runs in MS Excel. It requires data input for site-specific dissolved organic carbon, pH and calcium.
A Copper Bioavailability Tool has been developed that simplifies the integrated Biotic Ligand Model but runs in MS Excel.
This report provides estimates of ambient background concentrations (ABCs) for several metals and one metalloid in UK freshwaters.
The aquatic environment is sensitive to damage from a wide range of chemicals.
