Researchers sampled sediments from 16 sites within Lambert Channel and Baynes Sound, British Columbia. They found microplastics at all sites, the three main types being microfibers, microbeads, and microfragments. Microbeads comprised up to 25,000/kg sediment. The greatest number of microplastics was found within Baynes Sound, in Henry and Metcalfe bays—regions of intense shellfish aquaculture.
