Makes some public data for environmental risk assessment of plant protection products accessible in R. Includes definitions of substances in terms of well-defined chemical entities, if applicable. Also includes source references including page numbers, most often referring to secondary sources, as the original reports are usually unpublished. Uses standardised scientific names for biological species and includes physicochemical as well as ecotoxicological data. Data sources are mainly conclusions from the European pesticide risk assessment peer review process published by the European Food Safety Authority (EFSA) and Renewal Assessment Reports (RARs), also published by EFSA. Note that the use of the data included in this package for registration purposes may be restricted by regulatory data protection, also known as data exclusivity rules, as detailed for example in article 59 of Regulation (EC) No 1107/2009.
