Substances with persistent, bioaccumulative and toxic (PBT) or very persistent and very bioaccumulative (vPvB) properties are considered to be of particularly high concern in terms of the risks they pose to human health and the environment.
As these substances tend to be slow to degrade in the environment once released and to bioaccumulate in tissues of organisms, they are also referred to as persistent organic pollutants (POPs). Criteria exist for identifying and prioritising these substances under various national, regional and international regulations. For example, under REACH, substances identified with PBT or vPvB properties are subject to severe restrictions on their use and are ultimately likely to be phased out completely.
The assessment of PBT substances is complex and technically challenging. Ensuring that evaluations are undertaken based on sound science and with reliable information is essential to ensure appropriate regulatory decision are made.
Our team has extensive knowledge of PBT assessments and can provide support for undertaking these in accordance with best practice.
