Cellular and molecular responses of earthworm coelomocytes and antioxidant enzymes to naphthalene and a major metabolite (1-naphthol)

Mingyang Jing et al.

Summary: This study investigates the cytotoxicity and oxidative stress induced by naphthalene and its major metabolite (1-naphthol) on earthworm coelomocytes and the interaction mechanism with critical antioxidant enzymes (CAT and SOD). The results demonstrate that 1-naphthol is more toxic to earthworm coelomocytes than naphthalene, and it induces oxidative stress by binding to CAT and SOD. The binding of 1-naphthol leads to conformational changes and activity inhibition of CAT, while it has minimal effects on SOD.

Distribution of microplastics in soil and freshwater environments: Global analysis and framework for transport modeling

Vera S. Koutnik et al.

Summary: The concentration of microplastics in terrestrial environments can vary by up to eight orders of magnitude, with higher concentrations in inland locations such as glaciers and urban stormwater. Studies suggest that microplastic concentrations are lower in water bodies at terrestrial boundaries like estuaries. Fibers are preferentially transported to coastal sediments over inland water bodies, indicating potential differences in microplastic distribution patterns.
