“…Very interestingly, the mean ambient temperature correlated positively with PCBs in air and negatively with PCDD/Fs in soil, especially when considering the evaluation period between 2008 and 2015 (R 2 = 0.977 and R 2 = 0.978 for air PCBs and soil PCDD/Fs, respectively). The temperature-dependence of airborne PCBs has been already suggested by other researchers [23,24]. Moreover, it has been also observed that air temperature decreases the magnitude of deposition processes and increases the revolatilization of PCDD/Fs [25].…”

Since 2008, the environmental levels of polychlorinated compounds near a municipal solid waste incinerator in Mataró (Catalonia, Spain) have been periodically monitored. The present study aimed at updating the data regarding the temporal changes occurred between 2015 and 2017, when air and soil samples were collected again, and the concentrations of the same chemical pollutants (i.e., polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), and polychlorinated biphenyls (PCBs)) were analysed. Furthermore, the health risks associated with their human exposure were also evaluated. The levels of all the contaminants in soil were far below the threshold established by regional and national legislations, also being lower than those observed in previous surveys. A similar trend was also noted for PCDD/Fs in air samples, while airborne PCBs were the only group of chemicals whose levels significantly increased. In any case, the global assessment of the data regarding the different pollutants and matrices indicates that there has not been a general increase in the environmental pollution around the facility. In addition, the environmental exposure to PCDD/Fs and PCBs by the population living nearby is still clearly lower than the dietary intake of these same chemical pollutants.
