The pesticides contaminate the 63.9% of the Italian lakes and rivers and more than a third of aquifers, even profound. To give the alarm is the report released today by ‘ Ispra on the state of water contamination, which refers to the two-year period 2013-2014 . Compared to the previous two years, increases the level of contamination but also the number of substances found in the 3747 sampling points: 365 against 335 2012 . accused are particularly herbicides, as well as fungicides and insecticides. Among the substances present in surface waters, and aminometilfosforico glyphosate acid, a breakdown product of glyphosate, metolachlor, tricyclazole, oxadiazon, terbuthylazine and its main degradation product, desethyl-terbuthylazine.
In particular, Lombardy and Tuscany , the Regional Environmental Protection agency monitored the glyphosate and its derivative, the aminometilfosforico acid, finding that contaminate surface waters respectively in almost 4 case 10 and the first in over 7 out of 10 the second. Groundwater instead were found beyond the limits bentazone, metalaxyl, terbuthylazine and desethyl-terbuthylazine, atrazine and atrazine-desethyl, oxadixyl, imidacloprid, oxadiazon, bromacile, 2,6-diclorobenzammide, metolachlor.
About drink tap water should worry about? Ilfattoquotidiano.it has asked Peter Paris , head of the ISPRA Dangerous Substances and unit coordinator who made the Report pesticides . “We do not monitor water from the tap – clarifies – but of that of the water bodies. Very often, however, the levies for drinking purposes drawing from the same water bodies that we analyze. Almost always we have to resort to killing and purification systems in order to enter in the water faucet under, because surface and groundwater are polluted. An example? The Po , which is abundantly used to supply entire provinces with water to drink, but they must be purified. This goes against the fundamental principle behind the Framework Directive on the Waters, 60 2000 , which says that we must prevent the use of slaughter , ie avoid polluting instead of going to purify. The current one is an emergency system that attitude. “
After this report, will change anything? “We point out as always issues to the relevant ministries, primarily that of the Health , then of ‘ Atmosphere . But we have no powers of intervention – says Paris – and our opinion is not binding. We think are necessary measures. From the 2003 data that we provide we show that the water is contaminated by mixtures of substances. This year we find 48 substances several in a single sample. But pesticides, before being placed on the market are assessed and authorized individually. There is an overall risk assessment for mixtures and the rest are little calculable, because you form with unpredictable migration mechanisms and pathways. And ‘This is the most serious regulatory gap. “
A citizen who will read this article what he can do? “It can become aware of the problem. And to know that, however, by law, the managers of the aqueducts can not enter the contaminated water tap “the expert concludes.
