The role of persistence in chemical evaluations

The initial stage in the assessment and priority‐setting of chemicals for their potential to cause harm to humans and the environment is usually a hazard assessment employing metrics for persistence, bioaccumulation and inherent toxicity. This hazard assessment is followed, when necessary, by the more demanding task of risk assessment. Hazard assessment of data and processes influencing ...

Predicted no effect concentration (PNEC) derivation as a significant source of variability in environmental hazard assessments of chemicals in aquatic systems: An international analysis

Environmental hazard assessments for chemicals are performed to define an environmentally ‘safe’ level at which, theoretically, the chemical will not negatively affect any exposed biota. Despite this common goal, the methodologies in use are very diverse across different countries and jurisdictions. This becomes particularly obvious when international scientists work together on documents with ...

Methodologies to study the surface hydraulic behaviour of urban catchments during storm events

A good knowledge of the hydraulic behaviour of an urban catchment and its surface drainage system is an essential requirement to guarantee traffic and pedestrian safety. In many cases, inlets have been situated according to spatial density criteria. Indeed a more rational location of inlets on urban catchments must be defined according to an accurate analysis of the relationship between street ...

The use of probabilistic plume predictions for the consequence assessment of atmospheric releases of hazardous materials

Toxic load-based toxicity models have been increasingly applied to model the effects of atmospheric releases of hazardous materials. Although the majority of atmospheric transport and dispersion models predict only a ‘mean’ plume, real-world personnel are exposed to one of many possible individual realisations of a plume, and never to a ‘mean’ plume. Hazard prediction assessment capability ...

On the quantification of intertest variability in ecotoxicity data with application to species sensitivity distributions

Ecotoxicological hazard assessment relies on species effect data to estimate quantities such as the predicted no‐effect concentration. While there is a concerted effort to quantify uncertainty in risk assessments, the uncertainty due to intertest variability in species effect measurements is an overlooked component. The European Union Registration, Evaluation, Authorization, and Restriction of ...
