Sampling strategy
Sampling strategy - context
Environmental samplingSpatial variabilityDevelopment of a sampling schemeSpatial variability -> sampling scheme (1)Spatial variability -> sampling scheme (2)Temporal variabilitySampling and storage equipmentPotential sources of analyte lossesSample contamination
End of lessonEnvironmental sampling
| goal: | obtain a small yet representative portion of the sampled system |
| problem: | analyte concentrations vary in both space and time of the samples system or compartment |
| hence: | temporal and spatial resolution of sampling needs to be adapted to the pollutant variability in space and time |
Let 's look at an example on the spatial and temporal heterogeneity in pollutant distribution
