Tests have shown that the absorption of heavy metals was the cause of death for 30 dolphins that became beached on the coast in the city of Areia Branca, Rio Grande do Norte, in September last year. Tests performed in laboratories indicated that the cetaceans ingested mercury and other metals.

The materials reduced the animals' immunity, causing the proliferation of parasites in the dolphins’ intestines and heads. The tests found that the amount of mercury in the blood was 20 times greater than international standards.
