Growth, Physiological and Anatomical Behaviour of Cynanchum acutum in Response to Cement Dust Pollution

Ghada Abd Allah EL-Sherbeny and Ahmed Abdullah Najm

Abstract:
Background: Cement industry is one of the most polluting industry, that emits numerous pollutants as dust and heavy metals. Plants growing in the vicinity of cement industry are greatly affected by the pollutants emitted from this industry, so these plants could be used as air pollution monitoring. Materials and Methods: Cynanchum acutum plant was growing at the vicinity of studied factory and its growth, physiological and anatomical features investigated as biomonitoring for cement factory pollutants. Results: All plant growth attributes (shoot length, branches number, root length, leaf area and dry weight of shoot and root) at plant growing in the vicinity of the factory (polluted site) by 54.14, 61.16, 60, 60.01, 43.11 and 70%, respectively as compared to control site (250 m away from the factory). Chlorophyll ‘a’, ‘b’ and carotenoids as well as total soluble sugars and carbohydrates were reduced by 39.69, 18.61 and 28.57% as well as 56.03 and 43.48%, respectively at polluted sites as compared to control site. Anatomical investigation revealed that there was a reduction in the palisade and spongy parenchyma, reduction in the xylem vessels and increases in the density of phloem tissues. The estimated heavy metals (zinc, nickel, cadmium and lead) in soil and plant leaves showed a significant increases at polluted site as compared to control site. The dust amount on the plant leaves showed the same trend of heavy metals. Conclusion: Cement dust pollution showed a significant alterations in growth, physiological and anatomical features of Cynanchum acutum plant, which qualify it to monitor the cement pollution. Plants growing in the vicinity of the pollution is a best tool for monitoring pollution, where these plants exposed enough to the emitted pollutants. On the contrary, the air around the factory move by wind and the pollutants concentrations become poor reprehensive for pollution.
