Table 4 The Spearman correlation coefficients between mercury species in different media and exposure vavariables. Spearman correlation coefficients of inorganic mercury (IHg) and organic mercury (OHg) species in whole blood (B; μg/L), red blood cells (RBC; μg/L), plasma (P; μg/L) and urine (U: μg/L, adjusted to density 1.019) and IHg, OHg and total mercury (THg) in hair (H; mg/kg) and the exposure variables fish consumption (number of meals per month) and number of dental amalgam fillings. The number of samples are 25–28. The significance level is indicated as * p < 0.05; ** p < 0.01; *** p < 0.001.
