bio-met
The bio-met bioavailability tool is a ‘user friendly’ software tool, based on Biotic Ligand Models, for calculating the bioavailability of copper, nickel and zinc in different freshwaters

M-BAT
The metal bioavailability assessment tool (M-BAT) was developed for practitioners involved in monitoring, assessment and classification using the new “bioavailable” environmental quality standards that have been developed for a number of metals under the Water Framework Directive (WFD). The tool covers copper, zinc, manganese and nickel

PNEC-pro
PNEC-pro is a user-friendly tool for professionals dealing with assessment of surface water quality. The tool calculates local, water type specific predicted no-effect concentrations (PNECs) of copper, nickel and zinc, based on biotic ligand models (BLMs); a BLM-based calculation routine for the priority pollutant lead (Pb) has been included, too

Lead BLM Tool
The Lead Chronic Biotic Ligand Model Tool is a bioavailability-based approach for assessing the chronic effects of lead in the freshwater aquatic environment and combines bioavailability models with detailed species sensitivity distribution (SSD) analyses to derive hazard concentration of lead for a given water body

Lead Environmental Quality Standard (EQS) Screening Tool
This screening tool for the assessment of site-specific predicted no-effect concentrations (PNECs) for lead (Pb) can be used as part of a tiered risk assessment or as an early tier in an EQS compliance assessment. It allows  an initial assessment of risks associated with lead in a freshwater environment
