A recent study associates small amounts of fish consumption with increased risk of malignant melanoma, citing ocean pollutants like mercury and polychlorinated biphenyls (PCB’s) from plastic. No causality since it’s a prospective cohort study, but the N was just short of half a million people. The carcinogenicity of PBC’s is not new and elevated serum levels have been associated with prostate and breast cancer. Oh, and 46% of the plastic in the Great Pacific Garbage Patch derives from fishing industry waste.
