  Abstract Background and Objective: The impact of tectonic activities on environmental pollution was investigated by lead and zinc mines at Surmeh. Method: In this study, the 6EPA standard method was used and tested 7 times around the water and soil around the area and was expected to have adverse environmental effects, like other lead and zinc mines in the country such as Angoran and Zahabad. Finding: Studies have shown that the amount of lead in soil and water is standard for agricultural use and has little environmental impact. Discussion and Conclusion: Based on stratigraphic columns prepared in the Surmeh Mountains containing the salt marshes of the Hormoz and calcareous Dalan Formations and the Nare Evaporites, the tectonic effects of alpine activity acting in two tensile-shear and compressional conditions have resulted in the Dalan calcareous formation containing ore deposits. Lead and some clay minerals are marl, located in the core of the Surma anticline which provides salt diapirism conditions in different tectonic phases and eventually due to the calcium carbonate uptake in the Dalan Formation and the high uptake capacity of clay and salt minerals in the lead. Higher levels prevent lead release in groundwater and its derivatives in confined air and soil. Thus it can be said that the regional tectonics has resulted in the creation of a natural filter for active adsorption of lead in the range. Manuscript profile

  Micro algaes have a major role in food chains and aquatic ecosystems. Among the mono cellular algaes in the paddy fields which locted in Mazandaran state, Chlorella vulgaris is an important species in Chlorophyta phylum. Influence of herbicides as the most serious particle of pesticides on the algaes is very considerable. Thererfore this study is performed in orther to determination effect of pertilachlor on the some properties of Chlorella vulgaris. Nine treatments (0, 20, 30, 40, 50, 75, 100, 150 and 300 mg herbicide per 1 liter) prepared in one litter bottle, then 100 cc algae solution and stock culture was added, next this system aerated. Treatments with three replications during 24, 48, 72 and 96 hours were investigated. After treating, effect of pretilachlor on the desity, chlorophyll a concentration, activity of catalase, peroxidase, ascorbat peroxidase, polyphenoloxidase enzymes and lipidic peroxidation were examined. Herbicide increasing at the all times resulted in significant reduction about cellular density (p < 0.0001). Maximum and minimum cellular density was measured in the control (without herbicide) and 300 mg pertilachlor treatment, respectively. The less Chl a consentration was obsereved in the most dose herbicide. Activity rate of quadruple enzymes in long term (9 days), indicated significant loss with increasing herbicide dose. Also lipidic peroxidation in all treatments was more relative to control. In this study was shown enzymes activity in high pretilachlor concentrations was not enough that can prevent the reactive oxygen species and this material was targeted by herbicide.

  This research is trying to analyse and recognize the variables effecting OECD countries environment. As an index for measuring the environment pollution, we use CO1 emission, than using a panel data econometrics model to analyse the effects of economics growth and Good Governance on CO1 emission. The results show no considerable effects from these variables. Considering the history of using Green Tax in these countries, we used an econometrics model to see the effect of Green Tax on CO1 emission in OECD countries. The outcome supports the strong effect of Green Tax on CO1 emission in OECD countries. Manuscript profile
