The General Company for Electrical Industries may contribute in throwing many contaminations such as ( Ni ,Zn and Cu) by using these elements in the processes of electrical metal coating in the Department of Metal Coating in the Company .
Besides ,many of these elements are also used in different industrial products of the company .
Some of these elements may spread through the air to find their way into water , soil and the workers themselves by means of exposures ,such as breathing , digestions , as well as through the skin. The present study was designed to detect the levels of nickel , copper and Zinc by choosing random samples consisting of ( 25 ) samples , (7) of them were from occupational exposure samples (production staff) , (13) samples from environmental exposure samples (administrative) and (5) samples represented control sample (persons far away from the company site). 5 cm3 Blood samples were taken from the three samples as well as, samples of industrial waste water were collected before and after treatment to examine the efficiency of treatment and measure the elements concentration in industrial waste water. The results obviously showed different levels of these elements in all examined blood samples .
As for the zinc measurement , it was noticed that there were high levels of zinc (138.51±29.52 μg Zn/dl) in occupation exposure with probability P≤ 0.05 in comparison with the control sample (70.96±9.58 μg Zn/dl).
Also there were statistically significant differences in ( probability ≤ 0.05 ) in the environmental exposure samples (86.08 ±7.9 μg Zn/d) and the occupational samples.
The study showed that there is statistically significant relation between the period of exposure to the pollutants and the average concentration of zinc according to the correlation relation (r= 0.938) in probability level 0.01.
The study, however, couldn’t detect any significant differences between the number of syndromes and the exposure period. Either about copper, the study recorded its concentration in occupational exposure samples was (153.97±21.41μg Cu/dl) at (P≤0.01) as a compared with the control samples (68.53 ± 9.34 μg Cu/dl) ,as well as there were a statistical different (P≤0.05) between occupational and environmental exposure samples and the same probability value between environmental and control samples .The study recorded significant differences between the copper and exposure period according to the correlation relation (r= 0.936) at probability 0.01. The same thing in nickel that resemble copper except in the comparison between the occupational and environmental exposure samples because it was not recorded any relation according to t value =2.073 at P>0.05, but it was recorded significant relation (t=4.112; P≤0.01) between the control sample with each of occupational and environmental samples.
The study not clear any relation between nickel and exposure period according to the correlation relation (r =0.53). The study revealed very high levels of Zinc in the industrial waste water ,So its concentration before treatment reached (541.0 ± 94.269) p.p.m.
,while its concentrations after treatment was differed significantly than in before treatment and reached (2.225 ± 0.35) p.p.m.
also it was measured some physicals and chemical parameters like : Do ,BOD ,COD , TSS, TDS and pH and noticed that these values were differed after treatment than in before treatment .Also it was detected various levels of copper and nickel before treatment ( 8.20 ± 0.53 ، 5.075 ± 1.069) respectively and differ than in after treatment. The recent study and through the environmental results ,assured on the efficiency of the modern treatment method that used in treating the industrial wastewater according to the significant differences for all physical and chemical data before and after treatment.
