AI Article Synopsis
- Olive tree leaf samples were analyzed to assess their potential for biomonitoring toxic lipophilic substances, specifically focusing on 28 polychlorinated biphenyl (PCB) congeners.
- Twelve PCB congeners were detected, with PCB-60, 77, 81, 89, 105, 114, and 153 being the most prevalent, showing detection rates between 32% and 97%.
- The concentration of the Σ12PCBs in the samples ranged from below detection limits to 248 ng/g, with concentration maps indicating that olive leaves can effectively represent the spatial distribution of these pollutants.
Article Abstract
Olive tree leaf samples were collected to investigate their possible use for biomonitoring of lipophilic toxic substances. The samples were analyzed for 28 polychlorinated biphenyls (PCB) congeners. Twelve congeners were detected in the samples. PCB-60, 77, 81, 89, 105, 114, and 153 were the most frequently detected congeners ranging from 32 % for PCB-52 to 97 % for PCB-81. Σ12PCBs concentration varied from below detection limit to 248 ng/g wet weight in the sampling area, while the mean congener concentrations ranged from 0.06 ng/g (PCB-128 + 167) to 64.2 ng/g wet weight (PCB-60). Constructed concentration maps showed that olive tree leaves can be employed for the estimation of spatial distrubution of these congeners.
