Efficiency of some plants to reduce dust pollution in some areas of Baghdad, Iraq

Abstract

The efficiency of some plant species and their ability to trap dust particles in the areas of Al-Mashtal and New Baghdad were tested, represented by plants (Anastatica hierochuntica, Bougainvillea glabra, Citrus aurantium, Conocarpus lancifolius, Eucalyptus tereticornis, Morus alba, Myrtus communis, Nerium oleander, Phoenix dactylifera, Sesbania sesban, Washingtonia robusta, Ziziphus). The results showed the variation of the values of sedimentation rates on the surface area of the leaf in grams per plant, the results of the study proved that the best among the studied plants accumulating dust in the summer is Morus alba plant, as it reached 5500 g/plant, followed by Ziziphus 1655.3 g/per plant, then Sesbania sesban 1303.112 g/per plant, then Eucalyptus tereticornis 1190 g/per plant, then Myrtus communis 345.50 g/per plant, followed by Conocarpus lancifolius 210.25 g/ per plant as recorded Nerium oleander 77.34 g/per plant and Citrus aurantium 67.57 g/per plant and Phoenix dactylifera record 40.24 g/per plant followed by Bougainvillea glabra 21.5 g/per plant then Washingtonia robusta 16.7 g/per plant and was ordered last plant Anastatica hierochuntica 9.98 g/per plant. In winter, the best of them was the Morus alba 3332.55 g/plant, followed by Ziziphus 1421.55 g/plant, then Eucalyptus tereticornis 879 g/plant, then Sesbania sesban 567.65 g/plant, then Myrtus communis 256 g/plant, then Conocarpus lancifolius 149 g/plant, then Nerium oleander 55 g/plant, then Citrus aurantium 41.13 g/plant, followed by Phoenix  dactylifera 31.2 g/plant, then Bougainvillea glabra 15 g/plant, then Washingtonia robusta 8.2 g/plant and finally Anastatica hierochuntica 4.7 g/plant per plant.
