Low concentrations of methylmercury near the detection limit gave the dimensionless instrument readings: 187.5, 157.1, 144.5, 156.5, 201.5, 142.3, 205.3, 183.9, 116.9, and 187.7. Ten blanks had a mean reading of 41.1. The slope of the calibration curve is 3.78 x 10° M. Estimate the signal and concentration detection limits and the lower limit of quantitation for methylmercury. signal detection limit: concentration detection limit: lower limit of quantitation:
