Estimation of Measurement Uncertainties for the DGT Passive Sampler Used for Determination of Copper in Water

Table 2

Parameters for which uncertainty is determined and respective units.

Parameter	Unit	Definition
	m^2	Effective area of diffusional cross-section
	m^2 s^−1	Diffusion coefficient of the Cu^2+ ion in the MDL
	m^2 s^−1	Diffusion coefficient of the Cu^2+ ion in water
	g	Accumulated amount of Cu^2+ determined from sample
	g	Contamination determined from field blank
		Recovery during the extraction phase
	K	Temperature in bulk water phase
	hours	Exposure time
	m	Diffusional boundary layer thickness
	m	Diffusional pathway thickness of the MDL
