Using toxicology in risk-based decision making is essential in today's market, particularly in the detailed assessment and clean-up of contaminated land. SLR Toxicologists have high levels of technical expertise and extensive experience in all facets of this topic.
Toxicology and Contaminated Land
SLR uses risk assessment to form the basis of scientifically sound, but pragmatic decision making on all our land quality projects. We are highly experienced in using a wide range of national and international fate and transport risk assessment models and are knowledgeable in applying the most appropriate model for a specific scenario.
In addition, we have generated in-house generic assessment criteria (GAC) for a wide range of contaminant and exposure scenarios, and our staff have also assisted local authority, government and professional bodies in preparing contaminant assessment criteria.
Our experience ranges from detailed human health exposure assessments on development sites, through to hydrogeological risk assessments following major oil spills on industrial sites. We have also been at the forefront of soil vapour risk assessment for a number of years.
Toxicology and Chemical Risk Management
Chemical risk assessment is a growing requirement for the Chemical Industry and Regulators. SLR has undertaken chemical risk assessment projects for Industry, in particular relating to biocide hazard characterisation and risk assessment. This included dossier preparation of exposure scenarios for use of borate-containing chemicals in wood preservation by manufacturers, operators, and end-users.
We are also working on behalf of industry in defining risk-based labelling requirements for new chemicals. This work has focused on detailed toxicological review of toxicity studies conducted on laboratory animals, and providing recommendations regarding risk phrases that are appropriate based on potential human exposure and extrapolation of animal studies to occupational workers and other end users.
