Fibreglass particles a potential ‘forever’ contaminant, new research warns
New research indicates that fibreglass particles may pose significant environmental risks in marine ecosystems, particularly in the Cowichan Estuary. The study found high concentrations of fibreglass contamination in biofilm and sediments, raising concerns about its potential toxicity. Experts suggest that fibreglass could become a new 'forever' contaminant, similar to microplastics, but its effects are still not well understood.
