Assessment of Urban Air Quality in South Estonia by Simple Measures

摘要: In countries having limited resources, it is difficult to assess urban air quality on contemporaneously, due the absence of on-line information about pollution levels and emission rates. An alternative approach recommended for smaller cities with lower demands resources. The applied scheme consists a database sources (NOx CO from industry, traffic, domestic heating), simple Gaussian-plume model AEROPOL series measurements by passive monitors. This method was used in Tartu, small city situated valley river Emajogi, within landscape noteworthy topographical variations. Simulations annual average maximal concentrations were performed, fair agreement obtained NO2 monitoring results Palmes Inventories 1998 revealed that official statistics stationary covered 64% SO2,36% CO, 37% NOx 32% total particulate matter emissions. Recommendations measures reducing further investigations towards improving assessment management, are given.
