Persistent organic

The methods, which allow in one procedure of analysis to overcome, for example, most pesticides which are used in agricultural practice in the present time, get development and introduction in practice. The contribution of the Ukrainian scientists in field of chromatographic analysis of Persistent Organic Pollutants (POPs, chlorinated hydrocarbons, PCB s) and supertoxicants, such as PCDDs, is estimated.

This study assesses the uptake of persistent organic pollutants (a-Endosulfan, P-Endosulfan and Endosulfan sulphate) from lettuce. The lettuce plants were grown on compost that had previously been contaminated at 10 and 50 J.g/g.

Persistent organic pollutants (POP) and heavy metals were in the focus of interest until the begiiming of the 1990s and intensive monitoring programs and ecotoxico-logical studies had been conducted. As a result, due to adoption of appropriate measures and elimination of the dominant pollution sources a drastic reduction of emission of these nonpolar hazardous compounds have been achieved and today these compounds are less relevant for the industrialized countries.

The potential of the dimeric system 7 is perhaps best exemplified by its ability to bring about the total hydrodechlorination of decachlorobiphenyl, a member of the notorious family of polychlorinated biphenyls or PCBs (Persistent Organic Pollutants, POPs), in the presence of the inexpensive base NaOH (Table 8.3).

The trend from heavy metal and phenolic based biocides, e.g. mercury and pentachlorophenol types, to more environmentally acceptable but less persistent organic types, requires more attention to plant hygiene (Figure 6, Briggs, 1980).
