- •
Micronized copper treated lumber was assessed for copper and particulate release.
- •
~ 1.5 mg m− 2 of Cu was released during dermal contact.
- •
Release levels similar to ionic treatments on the market for 10 + years.
- •
Copper particles were released in the micro and nano ranges.
- •
Particulate copper released was mostly associated with larger cellulose particles.
- •
At levels found, children under age 8 could be affected by chronic ionic Cu exposure.
