Spider webs were gathered from residential and industrial areas to found the order of heavy suspended metals in the air. The treatment of spider webs were done with nitric acid and digested by atomic absorption spectrophotometer before analysis (AAS). The average value of several heavy metals concentration were observed to be meaningfully great at p < 0.05 in suspended ingredients in industrial zones including, Cadmium (Cd) 0.15 ± 0.05 and Lead (Pb) 0.53 ± 0.09 µgg-1, respectively. The average values of concentration of Copper (Cu), Nickel (Ni) and Zinc (Zn) were not meaningfully changed from residential, industrial and control zones. It was observed that, the heavy metals concentration reduces when the web specimens were collected more away from the road.
