摘要

Tree bark is a passive collector of atmospheric contaminants, with gas-phase organic compounds dissolving into bark lipids, and those associated with particles captured by the rough texture and high surface area of the bark. There is no "standard" for tree bark so high or low concentrations are based on comparisons to other sites. The results reveal the atmospheric contaminant exposure during the lifetime of the tree, with higher exposures indicating a nearby source. We used this approach when sampling and analyzing tree bark in Anniston, Alabama, the first site of polychlorinated biphenyl (PCB) manufacturing in the U.S.1 PCB results from Anniston showed a very strong and significant decline in tree bark concentrations (a high/low ratio of 4912) with increasing distance (up to 9 km) from the PCB plant site (see Figure 2 in ref 1). This plant site was about 380 m from the largest chemical waste disposal site, known as the South Landfill, on the northern flank of Coldwater Mountain, used for disposal of chemical waste from production at the Anniston Plant. The highest concentrations of ∑PCB in trees in this study were from specimens growing on a floodplain downstream from the South Landfill. Our bark results, and narratives from people living and attending community activities in the area,2 revealed extremely high concentrations of PCBs in bark, soils, and groundwater.
