The Claim
Coal mining activities in Candiota, Brazil, are associated with increased selenium exposure in children, as indicated by higher dietary intake and urinary excretion levels compared to children in a nearby non-mining city, with the mechanism of exposure remaining unconfirmed.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Children living near coal mines in Candiota, Brazil, have higher levels of selenium in their diet and urine than children living in a nearby city without coal mining.
See the scientific wording
Coal mining activities in Candiota, Brazil, are associated with increased selenium exposure in children, as evidenced by higher dietary intake and urinary excretion compared to children in a nearby non-mining city, but the mechanism of increased exposure remains unconfirmed.
Coal burning releases selenium from the ground into the air and soil, which gets into crops and water. Children eat and drink these contaminated foods and liquids, so their bodies take in more selenium. The extra selenium passes through their kidneys and shows up in their urine.
What the research says
1 studyKids living near the coal mines in Brazil had more selenium in their urine and food than kids in nearby towns, even though both groups were still healthy. This means the mines might be making more selenium available in the environment, but we don’t know exactly how yet.
