Giant otter (Pteronura brasiliensis) at risk? Total mercury and methylmercury levels in fish and otter scats, Peru

  title={Giant otter (Pteronura brasiliensis) at risk? Total mercury and methylmercury levels in fish and otter scats, Peru},
  author={A. Gutleb and C. Schenck and E. Staib},
Mercury and methylmercury levels in fish muscle and scats of the giant otter (Pteronura brasiliensis) of Manu National Park, Peru, and in one gold-mining area in the vicinity of its borders were analyzed. In 68% of fish muscles, total mercury levels exceeded the proposed maximum tolerable level of 0.1 mg kg-' fresh weight in fish for the European otter (Lutra lutra), and 17.6% exceeded 0.5 mg kg-1 fresh weight, the most common standard for human consumption. The ratio of methylmercury to total… Expand
