Atmospheric dust particles originating in the arid and semi arid regions of the world are known to be principal sources of mineral dust. The use of satellite remote sensing dust, the potential of this technique is created to provide valuable information to assist in the design of network measurement and estimation dust in marine environments. Dust deposited provides key nutrients such as iron to oceanic phytoplankton. Aerosol optical depth were reviewed in the study between March 2008 and December 2013 in the Persian Gulf. Aqua and Terra satellites for the MODIS sensor data as well as aerosol data (PM10) and Environmental stations and optical depth stations AERONET, used to evaluate the aerosol optical depth. The results showed that the data of MODIS AOD has acceptable accuracy and very high correlation between the values measured by MODIS and network AERONET, there (correlation coefficient: 90/0). Comparison between AOD values derived from measurements by satellites Aqua and Terra MODIS sensor and the amount of aerosol (PM10) estimated environmental stations in the Persian Gulf region also took place. The results showed that between these two values correlated to the Aqua and Terra satellites in the study area, and the correlation coefficient was greater in summer than winter. The results of this study showed that the optical depth data from the MODIS satellite images can provide accurate information dusts the Persian Gulf.

The Study of Petrochemical Industries Sewage Effects on the Water Quality in Khor Musa Abstract Imam Khomeini petrochemical complex is situated at the northwest part of the Persian Gulf where discharged its sewage to the seawater.Samples were collected using Van Dorn sampler, bimonthly from four sites during December 2009 to May 2010. The seawater physicochemical parameters such as DO, pH, BOD, total ammonia, total phosphorous and turbidity were measured and among them, BOD (5.05ppm), total ammonia (2.51ppm) and total phosphorous (0.3ppm) showed higher than standard values. Based on water quality scoring (WQS), all sites showed 2.66 values which classified as bad water quality. During this study, BOD, total ammonia and phosphorous showed significantly (p
