Carmel is also proficient in investigating the impact that agri-environment schemes and other policy drivers have on soil/water quality and ecosystem services.
Carmel’s work for commercial customers commonly includes bespoke experimental studies (including GLP-compliant studies) to generate data for dossier submission where specific (e.g. OECD) guidelines are currently unavailable, e.g. for biocides. She has expertise in generating environmental and human exposure scenarios for risk assessments and her work has been used to update policy advice regarding the recycling of ready-to-use pesticide containers in household waste.
Carmel is actively involved in research and was recently involved in 2 EU projects – Knowpec (Knowledge for Pesticides Control) and NaToxAq (Natural Toxins and Drinking water Quality – From Source to Tap).
More about regulatory risk assessment
Assessing the risks to human health or the environment of any chemical product is an essential part of the regulatory registration process. Preparing a detailed and thorough dossier of evidence and data is essential for a hassle-free product approval. We can help to ensure that you provide all the necessary evidence, compliance data and risk assessments to satisfy the requirements of the regulatory authority – whether for BPR or REACH registration.
