Environmental Hazards & Risks

Understanding the hazards and risks of chemicals is a key part of responsible product stewardship and is essential to sustainable business and compliance with chemical regulations such as GHS and REACH. Our in-house experts can help you with all aspects of environmental chemical safety assessment, enabling you to make informed decisions and supporting cost-effective regulatory compliance.


At NCEC, we have a broad range of expertise to assess the environmental hazards and risks of chemical products. These include all elements of the REACH chemical safety assessment (CSA)– data generation and assessment of ecotoxicology, environmental fate and physico-chemical properties; environmental exposure assessment; risk characterisation; and persistence, bioaccumulation and toxicity (PBT) assessment. We also have considerable experience in environmental monitoring and the management and remediation of contaminated land.

Our experience with the REACH regulation has been gained over many years of working for multinational chemical companies and within industry associations and consortia. It extends to the early days of its implementation, when industry SIEFs (Substance Information Exchange Fora) were forming and the first registration dossiers were being prepared for the 2010 phase-in deadline. Several years of regulatory evaluation (the ‘E’ in REACH) have followed, including reviews by the authorities of testing proposals, the community rolling action plan (CoRAP) and dossier compliance checks (CCHs), which necessitated continuous updating and refinement of existing registration dossiers with new data, justifications and approaches.

As a result, our experts have accrued vast experience of placing, monitoring and evaluating regulatory tests, as well as specialist expertise in developing alternative approaches to standard testing requirements – such as read-across/category approaches, data waiving, non-animal testing alternatives and computational quantitative structure-activity relationship (QSAR) or in silico methods. This enables us to support you in generating appropriate and reliable data of the highest standard, while minimising unnecessary testing costs and animal use, helping you to comply with ongoing regulatory requirements in the most cost-effective and ethical manner possible.

Our team also has considerable expertise in the evaluation and assessment of complex (so-called 'UVCB') substances; difficult test substances, polymers and nanomaterials; and in the PBT assessment of substances according to REACH Annex XIII requirements. This has been obtained through several years’ participation in working groups at:

  • Concawe (science division of the European Petroleum Refiners Association) 
  • Supporting the activities of the PetCo Working Group (part of the ECHA SVHC Roadmap to 2020)
  • CEFIC-LRI (long-range research initiative of the European Chemical Industry Council)
  • ECETOC (European Centre For Ecotoxicology and Toxicology of Chemicals) 
  • SETAC (Society for Environmental Toxicity and Chemistry).
