The purpose of this study was to investigate the effect of green roofs on air pollution in urban Toronto. The researchers looked for synergistic effects in air pollution mitigation by manipulating quantities and species of trees and shrubs at grade level and grass on roofs within the study area. The effect of these vegetation manipulations were simulated using the Urban Forest Effects (UFORE) computer model developed by the USDA Forest Service Northeastern Regional Station, Syracuse, New York. Originally UFORE was developed to help forestry managers and researchers quantify urban forest structure and risks based on standard field, meteorological and pollution data. While UFORE contains four different assessment modules A - D, Module D quantifies the effect of vegetation on air contaminants such as NO₂, SO₂, CO, PM₁₀ and ozone. UFORE also provides data about hourly air contaminant removal rates and it predicts an economic externality value in USD for total air contaminant levels. Results of the study indicate that grass on roofs (green roofs) could play a significant role in air pollution mitigation in an urban neighbourhood. By extension, a 10-20% increase in the surface area dedicated to green roofs on downtown Toronto buildings would improve air quality and quality of life for citizens of Toronto.

Canopy Coverage

This new 13-page article combines canopy coverage data from all of Florida's metropolitan and micropolitan areas with ecological models developed by the USDA Forest Service to calculate several key benefits of urban trees and an approximation of their monetary value. Benefits of urban trees include carbon sequestration/storage, air pollution filtration, and stormwater mitigation. Written by Drew C. McLean, Andrew K. Koeser, Deborah R.

The air pollution has a great impact on the social and economic aspects all over the world. Thus, the interaction of materials with the atmosphere has received increased attention nowadays. In order to estimate the impacts of air pollution on the solid surfaces a suitable scientific basis is developed and the well known Reversed Flow - Inverse Gas Chromatography, RF- IGC, is used. This dynamic experimental technique leads to very interesting experimental results through the determination of some important physicochemical quantities. The solids studied were Pentelic marble, white TiO2 pigment, ceramic and the gases were NO2 and C2H2. The synergistic effects between acetylene and nitrogen dioxide were also investigated. Through the curves obtained for each adsorption quantity determined versus time, one can easily and accurately conclude the result of the pollution impact on every solid mentioned above. The surface topography and the mechanism of deterioration can also be studied. All the above answer in detail to the questions of where, when and how the influence of gas pollutants on materials of cultural heritage takes place.
