Abstract:
This study aimed to estimate the level of air pollution in some portable heavy metals (lead and copper) in dust quarries by leaves of Laurus nobilis and Myrtus communis as biomonitor In site of Kfardabeel Stand- Jableh. The samples of dust and leaves were collected at the end of bioindicator July in 2020, Atomic absorption spectrophotometer was used to determine the amounts of lead and copper (ppm, dry weight).The average of accumulated metals in the Laurus and Myrtus leaves were estimated: (Cu=10.24 ppm ,Pb=0.68ppm) (Cu=10.28ppm, Pb =0.64ppm), while their amounts in the dust were done as following: (Cu=5.45 ppm, Pb =0.16 ppm).The results showed a correlation between heavy metals amounts in the leaves and their amounts in the trapped dust (r= 0.83) was detected, also regression equations have explained the variations in accumulation of studied metals in relation to the accumulated dust on leaves as following: Cu20%, 46% Pb. Consequently results confirmed the possibility of detecting the atmospheric Cu ,Pb pollution in the studied site using Laurus nobilis and Myrtus communis leaves as a biomonitor.
Key words: Laurus nobilis , Myrtus communis Lead, Copper,, biomonitor.
