According to an article entitled 'Risk Based Consumption Advice for Farmed Atlantic and Wild Pacific Salmon Contaminated with Dioxins and Dioxin-like Compounds' published in May 2005, (Foran et al., 2005, Environmental Health Perspectives, 113:552-556), substances such as PCBs, toxaphene, dieldrin, dioxins and polybrominated diphenyl ethers were found in much higher concentrations in salmon from European fish farms than in salmon from fish farms in North and South America.
