Evaluation by Chemical Parameters of the Pollution State of the Agricultural‐Industrial Settlement of the Fucino Plain

Abstract

In the present work are reported the results of a monitoring on a vast scale, carried out through evaluation of opportune chemical parameters, of the pollution state of the agricultural-industrial settlement of the Fucino Plain. The parameters took into consideration have been the presence of wide consumption pesticides and of ionic species as Cl-, NO2-, NO3-, NH4+, the quantification of the dissolved oxygen, of the temperature, of the conductivity, of pH and eH. Collected data are used for chemometric elaboration. The water systems examined, by means of drawing campaigns carried out at regular intervals in winter, spring, summer, and autumnal seasons, are represented by superficial waters constituting a network of irrigation canals fed by stratum and meteoric waters. In this work are reported the results relative to the drawing campaigns.

Influence of surface/groundwater interaction on pollution by pesticides in farmlands of the Fucino Plain, central Italy

“…The sampling points were selected on the basis of the previous survey conducted in (Ruggieri et al 2005, identifying those most susceptible to contamination (Fig. 3).…”

“…The occurrence of Linuron was particularly high (in June as high as 86%). Sporadically, also Atrazine, Iprodione and Procymidone were found (Ruggieri et al 2005).…”

“…Prior studies on the area suggested potential surface water and groundwater contamination from pesticides (Ruggieri et al 2005;Petitta and Burri 2006;Burri et al 2008), as well as a sharp increase in water demand and a natural decline in water supply (Burri and Petitta 2004;Petitta and Burri 2006). Investigations have also been conducted to determine potential groundwater contamination from fertilisers, which are also widely used in the Plain Burri et al 2008).…”

“…Moreover, both pesticides (Ruggieri et al 2005;) and nitrates ) have been detected both in the surface water and groundwater of the area in some periods of the year.…”

Numerical Simulation of Pesticide Transport and Fate for Water Management in the Fucino Plain, Italy

“…In addition, the decreasing discharge in the canals nullifies the effect of dilution of the pollutants entering surface waters, mainly residues of fertilizers [32] and pesticides. In this framework, surveys conducted on both surface water and groundwater have shown the presence of pesticides, mainly Linuron, Dichloran, and Carbaryl, with concentrations ranging from 0.02 to 2.8 g/L in surface water and from 0.03 to 0.5 g/L in groundwater [33]. Those concentrations are frequently higher than threshold values (0.1 g/L in groundwater and surface water for human use) allowed by Italian laws and European Union Directives [34][35][36].…”
