In addition to heavy metals, environmental factors affect to induce the synthesis of metallothionein (MT) contamination biomarker in vertebrates and invertebrates. Environmental parameters that were selected of nine stations in Chabahar Bay subtidal area (2013-14)  include temperature, salinity, dissolved oxygen and turbidity and heavy metals (copper, zinc, cadmium) in monsoon and post-monsoon, pre-monsoon, that studied relation them with polychaete metallothionein concentration. Total mean of MT was recorded in pre-monsoon 28.3±5.2, monsoon 15.50±4.9, and post-monsoon 21.39±4.37 µg/ g and ANOVA test showed significant differences among stations and seasons (p≤0.05). There were no significant correlation between metal concentrations in sediments and tissue in stations and seasons, also between metals and MT. Except for temperature and salinity were increased in monsoon, MT and other parameters showed a significant decrease in this season. In PCA test, three components of variance revealed a total of 75.24 variance percent that the second component with 28.73 variance percent was included oxygen and transparency and MT. Despite significant changes of MT and environmental factors in different seasons and also had not been recorded correlation of MT induction with metals, as the main factors in the induction, emphasis the role of Chabahar Bay environmental parameters on biomarker fluctuations. Among the factors under the PCA, dissolved oxygen of the main factors is effective in reducing the synthesis of MT in G.bonhourei.
