The Effect of Air Pollution on some Biochemical Parameters of Leaves of Three Tree Species Growing in the Industrial Area in Jeddah, Saudi Arabia

Abstract

The effect of industrial emissions on the levels of certain biochemical measurements in leaves of Camphor (Cinnamomum camphora), Henna (Lawsonia inermis), and Bougainvillea (Bougainvillea spectabilis) trees growing in the industrial zone in Jeddah -Saudi Arabia and Hada Al-Shame area (control) was done. Overall results showed that the content of chlorophyll a and b, total chlorophyll, carotenoids and protein in the plant leaf of the trees growing in the industrial zone were less comparing with the leaves of the trees growing in the control area.

Assessment of the Relationships Between Leaf Characteristics with Air Pollutants: A Case Study on Oriental Plane (Platanus orientalisL.) and Caucasian Hackberry (Celtis caucasicaWilld.)

“…The leaf area of Cinnamomum camphora (L.) Nees & Eberm., Lawsonia inermis L. and Bougainvillea spectabilis Willd. was decreased significantly in the industrial zone compared with the control area (Saudi Arabia) (Shaheen et al 2016). Areington et al (2015) showed that the leaf area of plants that had the closest distances to pollutants had a significant decrease compared to plants located farther away.…”

The influence of road traffic and industrial plant-induced air pollution on the physical, mechanical, chemical and morphological properties of the black pine wood

“…Which factor that occurs on the road side causes the prolongation of the tracheid lengths should be investigated with further studies. The determination of air pollution is made with some studies on the trees on the roadside (Shaheen et al 2016, Wuyts et al 2018. Some studies reported that Mn, Fe, Zn, Cu, Ni, Co, Pb, Ti, V, Cr, As, Zr, Mo, Se, Cd, Pt metals were detected in tree leaves and outer surfaces of trees implanted near the road (Krupnova et al 2021, Ram et al 2015.…”
