Changes of Metallothionein protein as biomarker in polychaete Glycinde bonhourei with effects Monsoon and heavy metals (Cu,Cd,Zn) in Chabahar Bay subtidal area

Among the many biochemical biomarkers used to assess contamination of the marine environment, metallothionein protein is considered as one of the very important and useful tool inrelated to biochemical markers metals. The aim of this study was to evaluate Metallothionein changes in natural condition in polychaete Glycinde bonhourei of 9 stations Chabahar Bay sub-tidal area from 2014 to 2015 with consideration before the monsoon season, monsoon, post-monsoon and concentrations of copper, zinc ,cadmium in the polychaete tissue. Total average concentrations of copper and zinc and cadmium respectively recorded in the monsoon 6.39±2.04, 20.95±4.51, 0.136±0.04 micrograms per gram dry weight of the monsoon season 3.51±1.46, 11.84±2.65, 0.059 ± 0.01 and in the post-Monsoon 4.98 ±1.44, 16.51±3.58, 0.152±0.01 microgram per gram of dry weight that one-way analysis of variance showed significant difference between the station and seasons (p
