Shipping pollution regulations 'could harm food chain'

Use of 'scrubbers' to cut air pollution increases pollutants pumped into sea, UN report says

New shipping pollution regulations introduced earlier this year could harm humans by contaminating fish and crustaceans with toxins, according to an internal report compiled by the International Maritime Organization and obtained by the Guardian.

In the report the IMO, the United Nations agency responsible for regulating shipping, says that there is insufficient "toxicity data" to be able to assess the risk to humans caused by the increased use of exhaust gas cleaning systems, which are also known as "scrubbers".
