Abstract :

This study aims to measure the amount of heavy metal lead in the effluent Haft Tapeh and compare it with Dez River in winter 2010 and spring 2011. First nine water samples using a rope marked at the desired depth within the sampling depth of effluent technology cultured in three stations in Haft Tapaeh. Hence measuring the concentration of heavy elements using graphite furnace method and atomic absorption with model elements Atomic Absorbtion PG_990 concentration were determined. In this study, average lead concentration in water inflow to the plant was 197 / 0 ± 511 / 0, average lead in the water discharged from the factory 40 / 0 ± 92 / 1, average lead after water treatment 273 / 0 ± 472 / 0. Lead concentration of water output after treatment compared with Dez River was lower (p <0.05). And limit the amount of lead metal, based on World Health Organization (WHO) was lower (p <0.05).
