Abstract: | Today, a significant environmental problem is due to the presence of industrial landfills, some of them old, which can release toxic compounds into the environment (Chemosphere 42 (2001) 415; Chemosphere 31 (1995) 3455). The identification of directly linked to the leachate tracers of contamination in the wells around the landfills, as early markers of a potential risk for the environment and/or man, is a good strategy for an early evaluation of contamination. Our protocol developed for wells water characterization is based on solid phase extraction combined with GC-MS and HPLC-MS/MS.In this way a list of organic contaminants of a specific industrial landfill is obtained, giving a solid basis also for the risk assessment. Here we present some specific examples and the use of these pollutants for environmental monitoring. |
