- Abstract
The aim of this study was to determine whether a combustion process (open burning) on an unsanitary landfill produces polychlorinated dibenzo-p-dioxins (PCDDs) and polychlorinated dibenzofurans (PCDFs), for which several media were analysed (smoked air, landfill soil, and lake sediment). The concentration of PCDD/Fs detected in the air increased over 4000 times during the landfill fire, from 0.480 fg m-3 to 1940.4 fg m-3 or expressed as Toxic Equivalency (TEQ) from 0.004 fg TEQ m-3 to 25.72 fg TEQ m-3. Increased values of PCDD/Fs were also determined in the soil from the landfill site (2597.6 ng kg-1, 48.11 ng TEQ kg-1), and the influence of combustion process occurring on the landfill was also registered in the nearby lake sediment (23.17 ng kg-1, 0.03 ng TEQ kg-1). Due to the high sedimentation rate (6.4 mm y-1), a significant contaminant dilution in the lake sediment can be expected. The results of this preliminary study point to the need of implementing a continuous long-term monitoring of PCDD/PCDFs in the landfill surrounding environment.
