WebThe rate of removal of atmospheric pollutants is directly proportional to the biomass of the tree (Nowak, 2024 ). Usually, healthy plants with 70–80 cm stem diameter absorb 60–70 times more pollutants as compared to the plants with 5–10 cm stem diameter ( Nowak, 2024). Green plants absorb gaseous pollutants through their stomata and leaf ... WebAcid deposition can lead to calcium being leached from conifer needles, e.g. red spruce (Borer et al 2005), which become less able to withstand winter freezing / desiccation …
