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…

Gold Mining and Mercury Bioaccumulation in a Floodplain Lake and Main Channel of the Tambopata River, Perú
Contamination of water bodies by inorganic mercury (Hg[II]) used in placer mining of gold deposits in the Madre de Dios Department, Peru, contributes to the bioaccumulation of methylmercury (MeHg) in
Mercury Biomagnification in a Tropical Black Water, Rio Negro, Brazil
TLDR
Fish Hg concentrations exceeding current safe limits for human consumption were found mainly in the piscivorous species, and opportunity fish catches in the Rio Negro habitat show high muscle-Hg derived from natural sources, but no systematic association with site-dependent geochemistry.
Mercury Levels in Human Hair and Farmed Fish near Artisanal and Small-Scale Gold Mining Communities in the Madre de Dios River Basin, Peru
TLDR
Examination of patterns in the total hair mercury level of human participants in several communities in the region and mercury levels of fish raised in local aquaculture ponds indicated that higher hair mercury levels were associated with residence in ASGM communities, aligning with other recent studies showing that ASGM activities are associated with elevated human mercury exposure.
Mercury concentrations in bats (Chiroptera) from a gold mining area in the Peruvian Amazon
TLDR
This study demonstrates that ASGM activities (and Hg point sources) increase Hg exposure in wildlife, and demonstrates the importance of considering feeding habits when evaluating Hg concentrations in bats and other vertebrates.
Distribution and status of giant otter (Pteronura brasiliensis) in the Pantanal wetland, Brazil
The giant otter (Pteronura brasiliensis) is listed as vulnerable in Brazil, is included in Appendix I of CITES and is classified as endangered by the IUCN. In Brazil, few viable populations persist
Mercury content in the fur of jaguars (Panthera onca) from two areas under different levels of gold mining impact in the Brazilian Pantanal.
TLDR
The data indicate that Hg is an important threat to jaguars within at-risk regions of the Pantanal, and therefore Jaguars show great potential to accumulate Hg by biomagnification.

TLDR
Methylmercury concentrations in hair are often at levels that may cause clinical symptoms of Minamata disease, and the greatest health hazard index values have been estimated for people eating contaminated fish.

TLDR
It is suggested that food shortage was most probably the ultimate cause of death in most otters in Shetland, with the effects of mercury and perhaps PCBs as contributing factors.

ABSTRACTDuring the last decade a new pattern of Hg pollution has been discerned, mostly in Scandinavia and North America. Fish from low productive lakes, even in remote areas, have been found to have

Mercury pollution due to gold mining in the Madeira river basin, Brazil.
TLDR
Air-mercury concentrations prove to be quite similar to control areas, but can reach very high levels in the vicinity of Au-Hg reburning locations, as well as in fish and human hair from the gold mining area along the Madeira River, SW Amazon.

TLDR
The purpose of this case series is to document mercury levels in miners and local villagers presenting with a history of exposure, or signs and symptoms consistent with mercury toxicity, in the Amazon River Basin.

TLDR
It is reported that both mono and dimethylmercury can be produced in bottom sediments and in rotten fish, and relate the findings to the hazards of mercury pollution.
