It truly is more and more famous that the best dangers of errors in environmental research lie within the pattern training instead of the research degree. This e-book describes the precautions that has to be taken from the sampling to the pattern pretreatment through the garage level to guarantee high quality. ordinary pitfalls - and suggestions for averting them - are mentioned. exact emphasis is given to the tracking of hint contaminants in environmental matrices (e. g., water, sediment, vegetation, air).
This booklet, in response to the event of experts, constitutes a useful advisor to the standard coverage appropriate to environmental chemists.

Of course the selection of a sampling strategy and sampling design has to follow the objectives of the investigation. For example, for testing the heavy metal contamination of agricultural areas according to the German sewage sludge decree , pooling of a fixed number of systematically taken samples is specified and the procedure has to follow exactly the legal instructions. For scientific or monitoring purposes it will generally make more sense to cover an area with a grid of adequate density (based on preliminary sampling or specific experience) and to analyze the samples separately.
Administrative inspections, proficiency testing, or both simultaneously. In several countries, the control systems for testing laboratories is based on IS0 Guide 25 . Within the European Union, Resolution 90/C/10/01 of the Council (21 December 1989) on "a global approach to conformity assessment" adopted guidelines developed in the European series of standards EN 45000  for testing laboratories and EN 29000 series (derived from IS0 9000)  for good manufacturing practice. The Council resolution promotes mutual recognition of accreditation systems developed in the various member states.
