Our expertise covers all aspects of the human health hazard characterisation and risk assessment of chemicals. We can support you with searches of the toxicological literature, development of testing strategies and employment of alternative approaches to testing.
Toxicology and Regulatory News
TRACE
Membership
Hazard assessments and characterisation based on a comprehensive understanding of the toxicological literature define the dose-response for all biological effects and routes of administration. Our expert toxicologists are highly experienced in summarising data including carcinogenicity, genotoxicity, reproductive and developmental toxicity and endocrine disruption.

Hazard characterisation of several e-liquid ingredients
Toxicological health risk assessments relate the health hazards of a chemical to its potential exposure levels. Our experienced toxicological risk assessors identify a critical health-based guidance value and estimate possible exposures to quantify the health risk to e.g. workers, consumers or patients.

Robust risk assessment relies on quality data. We have years of experience in literature monitoring and searching services, selecting and using search terms to obtain the highest quality, most relevant and reliable data for use in health hazard and risk assessments. Our in-house database, TRACE, gives immediate access to critical publications often not reliably captured elsewhere.

Read-across (using toxicity data on structurally- and chemically-similar compounds to evaluate a substance that has been inadequately tested) can reduce the need for new testing. Our toxicologists have extensive experience using read-across in regulatory submissions in many sectors.

Evaluating the health risks posed by extractables and leachables from an ENDS device
Our (Q)SAR services include modelling to predict physico-chemical or (eco)toxicological properties of a compound is a useful screening tool and can help reduce the need for costly and animal-intensive laboratory tests. Our team has extensive expertise in running several well-accepted models and interpreting the results.
In silico toxicology protocols
Genetic toxicology in silico protocol
Understanding the toxicokinetic (absorption, distribution, metabolism and excretion) properties of a compound is key to effective hazard characterisation. Our toxicologists can interpret existing data and produce TK and ADME assessments based on structure and physico-chemical properties.
Literature review and in silico prediction of metabolites
Safety benchmarking is an essential part of assessing the risk chemicals pose to human health. We specialise in identifying and deriving safety benchmarks, which represent the maximum exposure that will pose no significant health risk.

Commissioning laboratory animal studies should always be the last resort. Our experts can suggest where alternative testing strategies such as read-across, in silico predictions or in vitro assays could be used. If testing is unavoidable, we can commission and monitor the necessary studies and incorporate the results into hazard and risk assessments.

Endocrine-active chemicals, which can disrupt the action of hormones in the body potentially affecting normal growth and development or reproduction, are of significant toxicological and regulatory concern. Our experts are skilled in using all available data to conduct endocrine disruption evaluations.
