This record contains the PlastChem report "State of the science on plastic chemicals - Identifying and addressing chemicals and polymers of concern" and the associated PlastChem database (version 1.01). Chemicals are a central aspect of the plastics issue. Although there is a wealth of scientific information on plastic chemicals and polymers to inform policymakers, implementing this evidence is challenging because information is scattered and not easily accessible. The PlastChem report and database address this issue by comprehensively and consistently synthesizing the state of the science on plastic chemicals, including their hazard properties, and their presence in polymers. The state-of-the-science report provides the publicly available evidence to inform policy development that protects public health and the environment.

Version 1.01 of the PlastChem database (published on 14.05.2025) includes the following minor bug fixes: - added the missing mapping to original sources in rows 16112-16140 - removed old content from rows 17935 onwards (not associated with a chemical) - removed residual “NA” values across the database that previously occurred in some columns at rows 16112 and onwards - removed the duplicated column for “Bioplastics_unspecified” in column GU These changes do not affect the content of the PlastChem report.
