Microplastics and Other Anthropogenic Debris in Fish and Potential Implications for Human Exposures
Microplastics are an inconspicuous environmental threat that have received considerable attention due to global contamination and potential adverse ecological and human health impacts. Recent studies demonstrate that microplastics are ingested by aquatic organisms and can cause physiological and tox...
