Heavy Metals Found In High Levels In Sharks

The Tribune

Alarmingly high levels of 12 heavy metals, including mercury, have been found in the muscle tissues of large reef and tiger sharks in The Bahamas.

Researchers from the non-profit organisation Beneath the Waves (BTW) say the discovery has important implications for human health insofar as sharks are consumed by people.

“Over the last century, human activities have rapidly accelerated the influx of metals and metalloid entering the marine environment, posing potential risks to biodiversity and food security,” BTW said in a press statement yesterday.

“Evaluating muscle tissue of 36 individual sharks from six species, the results from this study provide the first amount of metal concentrations in sharks sampled in The Bahamas, a relatively pristine marine ecosystem where sharks live risk-free in large marine protected areas. Sharks are not commonly consumed by humans in The Bahamas.
