USA - California Proposition 65 - Findings in socks on Bisphenol A

The US based NGO, Center for Environmental Health (CEH) has been recently testing children, baby and adult socks from several brands for the substance Bisphenol A (BPA).
The substance is listed under California Proposition 65, also known as the Safe Drinking Water and Toxic Enforcement Act of 1986 of the State of California, for its developmental toxicity as well as female reproductive toxicity.

Under California Proposition 65, the Maximum Allowable Dose Level (MADL) for dermal absorption of BPA is 3 μg/day.
The NGO claims to have found concentrations that are by far exceeding the Prop65 MADL and has sent legal notices (60 Day Notices) to companies selling contaminated socks in California. The aim is, to get brands to reduce the use of BPA in socks as they can be worn for a long time and may harm especially vulnerable groups like babies and children.
