The EMA requires that an Environmental Risk Assessment (ERA) accompany every Marketing Authorization Application (MAA) for a new pharmaceutical. Likewise, the US FDA stipulates that a Risk Assessment or Categorical Exclusion claim accompanies every IND, NDA or BLA.

Guidelines follow a risk-based tiered approach based on environmental release of the pharmaceutical, with testing dictated by partitioning, solubility, PBT characteristics, and endocrine activity. 

Smithers has provided pharmaceutical companies of all sizes with impact assessment in the pharmaceutical industry for EU and US submissions over 250 drugs.
