Brazilian fish
Brazil's "G1" website reports that the study was carried out
by the Osvaldo Cruz Foundation (Fiocruz) in Brazil, the Institute for Social Environment (ISA), the Evandro Chagas Institute and the Federal University of Roraima (UFRR).
The researchers analyzed samples of 75 species of fish in four rivers in the state between February 27 and March 6, 2021, and came to these conclusions
based on a health risk assessment approach proposed by the World Health Organization (WHO).

The results show that the rio branco section, the lower Blanco river, the rio Mucajaí and the rio Uraricoera in the city of Boa Vista are all heavily polluted

Illegal gold prospectors often use mercury to separate gold from other sediments, after which they throw mercury into rivers, causing environmental pollution
.
Mercury is a highly toxic metal for humans, which is mistakenly eaten by animals in water and soil, and through the food chain, it will eventually endanger the health
of humans, especially indigenous peoples.

According to the study, 45 percent of the mercury metals used by illegal gold diggers were dumped in rivers and tributaries of the Amazon basin, and none of them were treated

The mercury content in some carnivorous fish is already so high that even if the human body consumes less, it will not meet the standard of
safe consumption.

Of the fish samples collected in the Urali kola River, 60% of the fish had mercury levels that exceeded the LIMIT set by WHO
.
In the Blanco section of the river in the city of Boavista, about 20 percent of the fish are not safe to eat

The researchers noted that the heavy mercury contamination of fish stocks in Roraima is a warning sign
.
Mercury emitted without treatment can persist in different environments for up to 100 years and cause a variety of diseases
in humans and animals.
