In all groups of mothers there was a highly significant correlation between fish consumption and total HHg concentrations: riverine (Spearman r = 0.8089, p = 0.001), urban (Spearman r = 0.7681, p = 0.001), rural (Spearman r = 0.7644, p = 0.001), and tin miner (Spearman r = 0.1211, p = 0.001); thus, confirming total HHg as a reliable biomarker of fish consumption [ 16 ].
