Microplastics in the first-year sea ice of the Novik Bay, Sea of Japan
Sea ice is heavily contaminated with microplastics particles (MPs, <5 mm). First-year sea ice cores (38–41 cm thick) were taken in the beginning of spring in a narrow populated bay of the Sea of Japan. Two ice cores were examined (layer-by-layer, excluding surface) for MPs content: one using μ-FT...
