This study aimed to estimate the level of air pollution in some portable heavy metals
in dust quarries by needles of Pinus brutia Ten. as biomonitor In site of Kfardabeel Stand-
Jableh. The samples of dust and leaves were collected at the end of Ju
ly in 2016, Atomic
absorption spectrophotometer was used to determine the amounts of Lead, Zinc, Nickel
(ppm, dry weight).
The average of accumulated metals in the needles were estimated: (Pb= 45.57 ppm,
Zn= 13.64 ppm, Ni= 7.64 ppm), while their amounts in the dust were done as following:
(Pb= 66.1 ppm, Zn= 15.8 ppm, Ni= 19.6 ppm). The results showed that the studied site is
polluted with Pb and Ni whereas Zn is in the natural range. a strong correlation between
heavy metals amounts in the needles and their amounts in the trapped dust (r= 0.98) was
detected, also regression equations have explained the variations in accumulation of
studied metals in relation to the accumulated dust on needles as following: 40% Pb, 40%
Zn, 20% Ni. Consequently results confirmed the possibility of detecting the atmospheric
Pb, Zn, Ni pollution in the studied site using P. brutia Needles as a biomonitor.
