Toxicological Risk Assessment

Determine. Treat. Improve.

Contaminated sites, contaminated locations and buildings, emissions and immissions of pollutants compromise product safety and occupational safety and lower the value of the product and building. Chemical substances must be recorded and quantified. Dangers are not immediately recognised. This is particularly true for combined exposures to pollutant mixtures. Our toxicological risk assessment tests the statutory risk thresholds, for example, cancer risks from IKR: 10E-5. For unacceptable risks and hazards, we will define, with you, location specific action quality and sanitary procedures. We will support you in your risk assessment.

Tasks

  • Assessment of hazards on contaminated sites and contaminated locations 
  • Definition and derivation of remediation targets, for soil, ground gas, ground water, by treating contaminated locations and contaminated sites
  • Evaluation of properties at locations and for reuse, as well as redevelopment costs and associated increases in property value
  • Determining of the risks posed by contaminated buildings, for example gas emissions affecting the air inside with PCB, PCP, flame retardants, and sanitation requirements which are essential for human toxicology 
  • Chemical Safety and Risks when applying for European legislation to REACH and others
  • Product safety in the case of human toxicity risks, such as in food, livestock feed, consumer goods as well as gas emissions in the interior of vehicles such as cars, aeroplanes and helicopters
  • Evaluate emissions and immissions, for example in the case of combined pollutant cocktails and assist with the optimisation of technical processes, for example exhaust air, sewage, and waste treatment
  • Assessment of work stations contaminated with pollutant cocktails

Our Services

  • Investigations of pollutants to determine pollutant cocktails for assessment, for example, in contaminated sites, contaminated locations, properties, buildings, products, emissions and immissions
  • Determining and defining exposure scenarios and exposure doses. Transparent application of well-known and scientifically best-based approaches and modelling modules for contaminant transfer from well-known U.S-EPA models, as well as Dutch, German, French, British, Canadian, Austrian and other application procedures
  • Quantification of toxic risks from pollutant cocktails with and without a dose threshold, for example cancer risks or systemic toxicological risks with scientific selection and derivation of toxicological dose response ratios (RFD, RfC, TRD, etc.)
  • Assessment of acceptable and unacceptable toxic risks and definition of follow-up actions, such as sanitation, safety, usage restrictions or other process optimization procedures
  • Derivation of quality or sanitation targets
  • Final assessment after the exclusion of unacceptable risks
  • Recommendations for the best possible cost-benefit assessment, such as the increase in real estate value to subsequent usage and redevelopment scenarios in the case of locations, buildings and the like

Your Benefits

  • Maximum legal certainty for site and building users, authorities and responsible parties by considering pollutant cocktails and their effects with the toxicological exposure risk quantification (TERQ method)
  • Also applicable for very complex pollutant mixtures, for example in military legacy munition or military chemical contaminated sites, in pesticide and metabolite cocktails
  • Applicable for pollutants without threshold limits
  • Provision of transparent toxicological risk assessments through traceable parameter applications and exposure quantifications based on TERQ
  • Cost-benefit optimization in property management, for example increasing property value through optimized utilization and remediation scenarios,
  • Budget and planning security without unacceptable residual risks
  • Expert assistance
  • Years of experience and local knowledge
  • Regional networking
  • Interdisciplinary services from one provider
