Environmental health teams require concise, defensible documents that connect exposure, hazard, and risk into clear language for internal decision-makers, regulators, and the public. Assignments focus on exposure characterisation and risk evaluations for chemicals, ingredients, formulations, and processes, together with technical memoranda and external statements coordinated with legal and corporate affairs. Materials are written in English and shaped so scientific specialists, communications leads, and policy stakeholders can rely on the same text.
Risk evaluations begin with the decision question and intended jurisdictions. Exposure scenarios are defined for workers, consumers, and the environment, with units, assumptions, and frequencies stated explicitly. Deterministic or probabilistic approaches are applied as appropriate; aggregate and cumulative exposure are considered where relevant. Hazard evidence is synthesised from authoritative bodies and primary studies, with study quality and relevance assessed against recognised criteria. Weight-of-evidence reasoning is made explicit, and key values—such as NOAEL/LOAEL, BMD/BMDL, DNEL/DMEL, and reference doses or TDI/ADI—are identified and justified for use in risk characterisation.
Calculations are transparent. Margins of exposure, risk-characterisation ratios, and threshold-of-toxicological-concern frameworks are applied with documented assumptions. For mixtures and impurities, contributions are isolated where feasible, and mixture methods are described without overstating certainty. When mitigation is warranted, options are presented with feasibility notes for labeling, formulation, process controls, or workplace practices so operations can act without delay. Vulnerable populations and life stages are flagged clearly.
Regulatory alignment is maintained throughout. For EU chemicals, deliverables can support REACH dossiers in IUCLID, Chemical Safety Reports, exposure scenarios, and Safety Data Sheet updates compliant with CLP/GHS. For nutrition and consumer products, outputs map to EFSA and regional guidance; for cosmetics, narratives reflect SCCS expectations. Where medical products intersect, safety sections align to ICH language and risk-management requirements. Region-specific differences are tracked so materials can be reused efficiently across jurisdictions while remaining accurate.
Public and stakeholder communication is handled with the same discipline. Executive summaries and Q&A notes translate technical content into careful wording suitable for non-specialists. Backgrounders provide primary references so legal and corporate affairs can respond rapidly to scrutiny. Where appropriate, plain-language summaries are prepared for websites or community briefings.
Operational delivery is predictable. Draft one lands on the scheduled date with tracked changes and a comment log explaining key decisions and references. One focused revision round is included. Handover includes the technical memorandum or report, editable vector figures, calculation sheets, and a managed bibliography ready for audit and archiving. Confidential material is handled under NDA with encrypted transfer, named-user access, and retention limited to the period specified in the statement of work. Assignments are executed in English for organisations across Europe and beyond, with contracting and invoicing available in CHF, EUR, NOK, or DKK.
