The BCR-programme on environmental analysis covers a vast area of matrices, determinands and concentrations. In the last few years many trace elements such as Hg, As, Pb, Zn, Cu, Se ... were certified; other trace element certifications are under way. The programme was enlarged with organic pollutants in various matrices, of which the measurement of chlorinated compounds (biphenyls, dibenzodioxins, dibenzofuranes and pesticides) is most advanced. CBs were certified in fish oils and sewage sludge and the "dirty" CDDs and CDFs will be certified in 1990 in an incinerator flyash. The work on organic trace pollutants will be extended further, e.g. with industrial wastes. More emphasis was recently given to speciation of trace metals in environmental matrices (e.g. tributyl tin, methyl mercury, arsenobetaine Cr (III) and (VI) and binding of trace metals to various soil fractions). A lot of work is being done to solve problems in monitoring occupational air. Materials to verify the performance of the final analytical step and sampling techniques are being studied. Recent achievements are briefly described, together with a survey of various on-going projects. Examples of the care and methodological improvement necessary for certification are also given.
