Analytical procedures for determining of pollutants in the environment are known and
Recognized as standard analytical procedures, however, determining individual compounds
In natural samples can represent challenges and difficulties even for experienced analysts.
Samples from the environment demand through preparation and an in depth knowledge of
The analyst’s instrumentation.
Common difficulties for the analytical chemist include:
- Natural samples are complex mixtures so the sample preparations should be specific to sample media and targeted substance.
- Concentrations may have to be intensified.
- Many natural chemical events act as interferons,
- Requirement to know the law where the findings maybe used in a prosecution
Analytical practice will be done in the first instance with non-harmful substances and then
Controlled quantities of harmful substances commonly found in the environment using a
Selection of different matrixes; these include:
- Heavy metals
- Organic industrial solvents
- Polychlorinated biphenyl
- Mineral oils
- Depleted Uranium
- The matrixes which will be processed are: soil, water, air and silt in water.
