Evolution Of Air Pollution Tolerance Index Of Selected Plants Chosen For Green Belt Development In Al-Nasiriya City - Southern Of Iraq

Abstract

Dust is one of the most important air pollutants that the city of Nasiriyah suffers from. Therefore, air pollution tolerance index (APTI) was evaluated in three stations by measuring biological indicators in three plants: Ziziphusspinachristi, Conocarpuslancifolius and Eucalyptus camaldulensis to determine their ability in tolerating the pollutants, in order to select the tolerant plant for building the green belt surrounding Nasiriya city. The study extended from September 2020 to August 2021, and the results showed that Eucalyptus was the most tolerant between the three plants; APTI value for Eucalyptus was (15.02), and according to APTI value (Singh et al., 1991) Eucalyptus considered moderate tolerant for air pollution in Nasiriya.
