Correction: Risk Factors for Mercury Exposure of Children in a Rural Mining Town in Northern Chile

The Hg-values of n = 5 children analyzed by the authors were recorded with an incorrect unit, and should instead have been 1000 times higher. The authors have now updated all results based on the new, correct values. The authors apologize for this error and confirm that the main results remain when calculated based on the correct Hg-values. Please see an updated version of Table 4 here, which displays the final adjusted associations. The main changes include: • A slightly smaller OR of the main association between 'Hg work in household and child playing inside' and Hg-values > the 75th percentile (new OR = 3.32, 95% CI 1.26–8.73) vs. (old OR = 3.49, 95% CI 1.23–9.89). • Traditional gold mining is now a risk factor of having Hg-values > the 75th percentile, when compared with industrial gold mining (OR = 2.05, 95% CI 0.39–10.70). • The updated Hg-value corresponding to the 75th percentile is 0.177 ug/g (old value = 0.165 ug/g).
