Abstract: |
Daily air pollutant uptake by trees in a 525 acre (212 hectare) section of Lincoln Park was estimated for four different pollutants and two scenarios: concentrations at the National ambient Air Quality Standard (NAAQS) and normal levels. The value of air cleansing was implied using costs of traditional air pollution controls. The annual air pollution mitigation value of trees was approximately %25,000. Assuming the NAAQS scenario, greatest benefits where received from interception of particulates ($355/day) and absorption of sulfur dioxide ($99/day). Accounting for the environmental services that urban greenspace provides can be a first step to justifying public and private investment in the "green infrastructure" of our cities. |
