Petrochemical Industries are potentially capable of having impacts on environment due to the nature of these activities and the production of waste water, pollutant gaseous emissions and hazardous wastes. This case study has considered the adverse environmental impacts of petrochemical industries on existing habitats in Mahshahr Special Economic Zone with respect to the regionally significant biological diversity and ecologically valuable species. When results from regional estuary biological and physio–chemical quality sampling as well as of impacts from petrochemical industry pollutants has been analyzed and studied, the affected ecosystems have been ranked using the Analytic Hierarchy Process method, Expert Choice software and the Eigenvector technique. The study’s outcomes show that, with respect to the essence of petrochemical industry pollutants in the region, specifically waste waters including heavy metals, oil and grease, COD, TSS, along with principal standards, criteria defined in the AHP method (such as ecological value, protecting value and exposure), estuaries represent the most affected ecosystems in the region. On the other hand, different types of fish and benthic, such as Decapods, Gastropods and Tanaida have been highly affected by the consequences of the petrochemical industry’s activities. It is concluded that deposits of heavy metals, oil and grease into the environment are the most important sources of pollution for the regional estuaries and these should be controlled.

For assessment of water quality in Gharasou River, located in the Northwest of Iran, multivariate statistical analysis was used. During the period of one year, 18 physical, chemical and microbiological parameters were sampled in 11 sampling stations. The measured data were analyzed by a multivariate statistical approach, Cluster Analysis (CA). Based on CA analysis the stations were divided to three groups of highly polluted (HP), moderately polluted (MP), and less polluted (LP) stations. The results of the study revealed that multivariate statistical techniques are an effective statistical method for water quality assessment, identification of pollution sources/factors in water quality for effective water quality management. As Extracted clustered information can be used in reducing the number of sampling sites on the River without missing much information.

Zakherd watershed "with area of 82.23 km2" is located in the North west of Shiraz and East of Kazeroon in Fars Province.The evaluation of ecological land capability is considered as a core of environmental studies , as well as, preventive, and remedical measures for environmental crisis.So before the implementation of development ,it is necessary to know about the ecological potential of land for different uses.In the Zakherd watershed evaluation is carried out by Mc.Harg method,2001 makhdoum Rural development ecological model and system of GIS. By this research ,at first regional environmental resources was identified. Digital data with accompany of attribute data is entered into the Arcview system to make data base. Therefore, by overlaying information layers in the mentioned system the ecological unit map of area with the table of characteristic unit , and then the evaluation of capability was done.The result of survey shows that to the point of whole ecological parameters , the total region is not appropriate for rural development but by omitting of elevation parameter that it's the last choice in the Makhdoum ecological model . 8.49% of land for rural development has a suitable (grade 2) and 91.51% of the other has not a suitable potential for rural use.For the complement of ecological evaluation ,valuating needs,socio- economic indicator and facilities was done in the area so the three nappe of Zakherd, Elyasabad and Hematabab was put to make clear the hairchy of rural development.By the result of search it's made clear that Hematabad nappe has better choice.

In this survey, a study of hospital waste management in Tehran’s private hospitals has been conducted to assess separation, collection, storage, disposal and onsite and offsite transportation of such waste. 20 out of the 48 operating private hospitals have been selected for the study which was conducted using a questionnaire. Waste generation rate has been evaluated at 3.406 Kg per bed. All hospitals have been evaluated as having similar performance levels in waste separation which has been designated the score level of 100. Scores for waste transportation inside and outside the hospital premises have respectively been evaluated at having mean levels of 93.3 and 76.25. Temporary waste storage areas have gained the mean score value of 80.36 for alignment with environmental and health standards. None of the hospitals have adopted treatment technologies and Tehran municipality takes care of the collection and disposal of all hospital waste. Waste disposal is assessed as inefficient according to WHO standards. In this survey, hospital waste management practices have been evaluated as acceptable in areas of waste separation, collection, onsite transportation and temporary storage. Management practices in areas of offsite transportation and final disposal are barely acceptable or weak for reasons out of hospital’s control such as poor coordinationbetween responsible parties and lack of proper standards and guidelines.

Industrial Estate of Rasht is one of the oldest Industrial Estate of Iran in Guilan province .It was established before the Islamic republic of Iran's revolution in 1974 .The Industrial Estate of Rasht that is the greatest active Industrial Estate in the province is located at 18- kilometer of western south side of Rasht city. In this article, solid waste management has been studied as one of the problems of this Industrial Estate. The method of this article has been on the basis of observation and completion of subjective questionnaires distributed among 61% of the active industrial units. Study of finding show that majority of industries, have a passive approach toward remarks of environment protection, absorption of environment experts and scientific management of Solid wastes. In this regard, only 13.4% of the units have environment experts, 14.9% of industrial units have taken an action for studying their solid wastes. For this reason, two industrial units have been able to selected as Green unit in Guilan province. Metal and nonmetal mineral Industries groups have the most amount of industrial solid waste with 26.80% and 20.72% respectively, and Metal Industrial groups with 19% and textile industries with 15.23% have the most weight of House-hold solid wastes. About 4.45% of the units have recycled their solid wastes and 21.20% of them do the recycling together with other management activities such as source reduction, incineration and Sanitary Land fill. About 1.51% of industrial units have incinerated their Solid Wastes but no precise control is made on air pollution. In summary the industrial units under study in Industrial Estate of Rasht produce 3903.8 tons of industrial solid wastes per year and 217.2 tons of House-hold solid wastes per year. According to the obtained results, upon development of industrial activities in factories and increase of the number of staffs, the volume of produced solid wastes will increase in future. Accumulation of these wastes in the Industrial Estate will create undesirable environmental effects and more consumption of resources. By applying an integrated solid waste management system in Industrial Estate of Rasht, production of solid waste is decreased and increasing industrial development will be maintained.
