In this work the degradation of the herbicides metolachlor, diuron, monuron and of the metabolites 2-ethyl-6-methylaniline (EMA), and 3,4-dichloroaniline (DCA) was assessed in laboratory experiments on microbiologically active and sterilized soils. Their leaching potentials were calculated, using Gustafson's equation, by determining their mobility (as Koc)(More)
The toxicological assessment of medicinal products (MPs) and their residues and metabolites in the environment have become a challenging task worldwide. The contamination of environmental compartments, biota, workplace, foodstuff and feedstuff by residues and metabolites of these substances poses a risk to human health which is still far from being fully(More)
Pharmaceuticals, among the emerging contaminants, are one of the most relevant groups of substances in aquatic ecosystems due to universal use, their chemico-physical properties and known mode of action in aquatic organisms at low concentrations. After administration many drugs and their transformation products are only retained to some extent in wastewater(More)
Once in soil, pesticides undergo degradation processes that give rise to a complex pattern of metabolites. Those presenting a significant percentage of formation, genotoxic and leaching properties may pose a threat to human health associated with the consumption of drinking water. The aim of this study is to assess the hazard potential of some metabolites(More)
A lot of data and information are available regarding the presence of pesticides in ground-waters or their tendency to contaminate them. Despite this, for a very large number of pesticides these data and information are almost completely lacking. Many theoretical methods have been proposed to predict the leaching potential of pesticides. Persistence(More)
The metabolites of pesticides can contaminate groundwater and pose a risk to human health when this water is used for drinking. This paper reports the results of a laboratory study on aldicarb and its main metabolites, aldicarb sulfone and aldicarb sulfoxide. Aldicarb and its metabolites showed Koc values (6-31) which were lower than that of atrazine (55),(More)
With a grant from the Italian Ministry of the Environment, the National Institute of Health (Istituto Superiore di Sanità) promoted and coordinated some activities aimed at determining the extent and the intensity of contamination of waters used for human consumption by some chemical agents, and describing causes and modalities of contamination and human(More)
Pharmaceuticals and their metabolites can reach water bodies through sewage systems, industrial discharges, effluents from sewage treatment facilities, aquaculture and livestock farming. Pharmaceuticals include a huge number of substances which are very different as regards their chemical and physical properties and environmental behaviour, although they(More)
