Figure 5. (A): Calibration curves for MeHgBr and (B): EtHgBr. Concentration of analytes and response ratios are based on 0.5 mL samples spiked with the internal standard (10 ng of TCA-d3). Linear portions were fitted with a weight of the inverse of concentration. Linearity (R2) was 0.987 for MeHgBr and 0.990 for EtHgBr.
