Effect of industrial acid rain on the biochemical properties of some common plants in Tikrit

Abstract EN

This study was conducted in Tikrit to compared between the plants used in decorating the sides of roads and public parks according to their ability to withstand the conditions of industrial acid rain in order to recommend them in afforestation industrial parks and areas of traffic density.

Where different concentrations of industrial acidic rain were used (pH2, pH4, Ph6 and pH7.2) as well as five common plant species used for landscaping and road sides aspects (Calistemon viminalis ,Nerium oleander, Olea europaea L , Myrtus communis , Dodonaea viscosa Linn).

The plants varied in their tolerance according to the plant species and by acid precipitation concentrations of all the properties in the study [concentration of ascorbic acid (mg/g) and total chlorophyll (mg/g) and pH of the leaf extract (pH) and the relative water content of the leaves(%)].The result showed that the best plants tolerate the conditions of pollution and according to the index of APTI (Air Pollution Tolerance Induces) were (Calistemon viminalis < Myrtus communis < Dodonaea viscosa Linn < Olea europaea L < Nerium oleander).

It was also observed that one plant has different sensitivity to the acidic industrial rain by acid concentration.

Some plants in the study were sensitive to a specific concentration but were relatively tolerant or moderately tolerant at other concentrations
