Abstract
Pollen grain samples collected from pollen trap are analyzed for Pb, Cd, Zn, and Cu levels. The results showed that the levels of lead: 0.0028, 0.136, 0.0001, 0.033, 0.004, 0.0263, 0.001 and 0.0426 (ppm) in Edku (A, B), Kafr-Eldawar (A, B), Nobaria (A, B), Abis2 (A, B) respectively. The highest concentration of lead (0.136 ppm) from Edku (B) and the lowest level (0.0001ppm) from Kafr-Eldawar (A) in 2015, while 2016, the maximum content of lead was recorded in Abis 2 (A) with a mean value of 0.2120 ppm while the minimum content determined (0.007 ppm) in Edku (B).
The highest levels of Cadmium was recorded from Al-Nobaria (B) with mean value of 0.1010 ppm and the lowest mean was detected from Abis 2 (B) which had (0.0510 ppm) during 2015, while 2016 the highest concentration of cadmium (0.084 ppm) from Edku (B), the lowest level (0.0171 ppm) from Kafr-Eldawar (B).
The pollen grain samples from Edku (B) recorded the highest level of Zinc with a mean value of 1.853 and the lowest level of Zinc (1.3044 ppm) from Kafr-Eldawar (A) during 2015, in 2016 the maximum content of Zinc (2.0538 ppm) while , the minimum content of Zinc (0.8048 ppm) from Abis 2 (B) and Nobaria (B) respectively.
The highest level of copper content was recorded in pollen grain samples collected from Nobaria (A) with mean value of (3.018 ppm), the lowest level (0.614 ppm) recorded in Abis 2 (B) during 2016, while, the maximum content of copper was determined from Abis 2 (B) with a mean value of (6.299 ppm) and minimum content was recorded (2.14 ppm) in Edku (A).
