## Sampling Plan for Cadmium Leeching from Strip Mine

One of the hazards of strip mining is that water passing through the mine’s “tailings” (the piles of discarded material) is often very acidic and contains high concentrations of metal ions, such as Pb2+ and Cd2+. (a) Suppose you are … Continue reading

## Developing a Sampling Plan for Lead in Soil

When leaded gasoline was available, automobiles were a significant source of the total yearly environmental emission of Pb. During internal combustion lead in gasoline, which was present as tetraethyl lead, was vaporized. The lead, now present as Pb0, adsorbed to … Continue reading

## Sampling M & Ms

Carry out the following “experiment” to test the validity of the sampling constant equation mR2 = Ks where m is the sample’s mass, R is the relative standard deviation for sampling, and Ks is the sampling constant. Obtain a package … Continue reading
