California Initiates Regulatory Process for Microplastics by Adding Them to Candidate Chemicals List
California is taking a significant step towards regulating microplastics by officially adding them to its Candidate Chemicals List, effective October 1. This action is a procedural prerequisite by the California Department of Toxic Substances Control before specific microplastic-containing products can be designated for regulation. While this listing does not immediately impose restrictions, it opens a crucial legal pathway to address microplastic pollution, which has been detected in various environments, including water, food, and human tissues. A recent paper co-authored by Stanford University scholars, published in Frontiers in Environmental Science, highlights California's decade-long efforts in microplastic regulation and offers insights for other jurisdictions. The paper emphasizes that microplastics can act as 'Trojan horses,' carrying thousands of other chemicals and polymers, including plasticizers like BPA, which have documented health effects.
