Levels surpassed safety limits

With mercury levels surpassed safety limits in 77.6% of carnivorous fish, 20% of omnivores, and 2.4% of herbivores, researchers found the fish in the region unfit for human consumption. 

As per the study, consumption of more than 200gm of these fish species could be lethal. Conservationist Marcelo Oliveira of WWF-Brazil was reported blaming illegal gold mining in the region for the high levels of mercury in the fish. As per reports, he said that the recent findings highlight the level of destruction being caused by illegal gold mining in the Amazon.

Brazilian President Jair Bolsonaro has been time and again criticised for loss of protected lands in the Amazon, with forest covers being cleared for mining and agricultural activity. Researchers have warned that large scale human activities will accelerate the destruction of the world’s biggest rainforest.
