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.


  • 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

  • Erkundungen und Schadstoffermittlungen der zu bewertenden Schadstoffcocktails, zum Beispiel bei Altlasten und kontaminierten Standorten, Immobilien, Gebäuden, Produkten, Emissionen und Immissionen.
  • Ermitteln und Definieren von Expositionsszenarien und Expositionsdosen. Transparentes Anwenden bekannter und wissenschaftlich am besten basierter Herangehensweisen und Modellierungsmodule zum Schadstofftransfer aus bekannten Modellen der U.S-EPA, niederländischen, deutschen, französischen, britischen, kanadischen, österreichischen und weiteren Anwendungsprozeduren
  • Quantifizierung toxischer Risiken von Schadstoffcocktails mit und ohne Dosis-Wirkungsschwelle, also zum Beispiel Krebsrisiken oder systemische toxikologische Risiken mit wissenschaftlicher Auswahl und Ableitung der toxikologischen Dosis-Wirkungs-Beziehungswerte (RFD, RfC, TRD, etc.).
  • Bewerten akzeptabler und nicht akzeptabler toxischer Risiken und Definition von Folgemaßnahmen wie zum Beispiel Sanierung, Sicherung, Nutzungseinschränkung oder -änderung, Prozessoptimierung
  • Ableiten von Qualitäts- oder Sanierungszielen.
  • Abschließende Prüfung des Ausschlusses nicht-akzeptabler Risiken.
  • Handlungsempfehlungen zur bestmöglichen Kosten-Nutzen-Bilanz, wie zum Beispiel Immobilienwert-Steigerung zu Folgenutzungs- und Sanierungsszenarien bei Standorten, Gebäuden und Ähnlichem

Your Benefits

  • 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
