Marine mussel-based biomarkers as risk indicators to assess oceanic region-specific microplastics impact potential

Microplastics (MPs) pollution in the ocean is an area of growing concern. Marine fauna subject to MPs exposure from various environmental sources are most likely to have detrimental effects on their immune system. However, studies of potential risks of MPs on marine ecosystems in light of environmen...
