Presence of plant protection products in three agricultural areas of Regione Lazio.
Aim of the research was to verify the impact of plant protection products on three significant agricultural areas of Regione Lazio: Maccarese, Cisterna di Latina, Sabaudia-Terracina. This research studied the presence of some active ingredients, indicated by technicians as distributed, on soil, water, crop and air samples, the last one in greenhouse; the analysis, carried out by multi-residue methods, allowed to investigate also on a large amount of active ingredients not indicated by technicians. The determinations have been obtained, using internal standards, by GC-NPD, GC-ECD, HPLC-UV, HPLC-DAD, with different columns, conditions and wavelength of adsorption. Taking into account the results we could to assert that only a small part of the molecules searched were found in the samples and that they are typical for the crops and the environment treated. In greenhouse, more persistence was founded in wood greenhouse, treated from the outside, probably for the release of a.i. in time from wood and for a better distribution. The active ingredients more frequently founded must be controlled to avoid possible accumulation or leaching, especially for herbicides in the areas of Maccarese and Cisterna di Latina. Furthermore, the molecule on which more attention must be done when applied, are: linuron on carrots, penconazole on zucchini and cymoxanil, often used inappropriately, particularly on minor crops, like red-radish. Although the number of sampling was limited, it has been possible to outline the situation in the three zones considered, for directing choices, that could be more sensible at sanitary spin-off and at the environment.
