Because of numerous industrial units, especially refineries, in Bushehr province, it is essential to find a management solution for hazardous wastes of this province. Finding the optimal location using multi-criteria decision models based on GIS that has both the lowest environmental risks and economically optimal, is the main goal of this article.Method: In this study, 24 parameters were used to analyze the selection of hazardous waste disposal sites based on the Delphi method in Bushehr province. Selected criteria were divided into two ecological and economic categories and ANP method was used to weight the criteria. At the final stage, suitable sites for these wastes were determined based on the GIS-based WLC method. Findings: The results showed that ecological criteria had the highest score (61/34%) and land use had the highest weight (0/27) and evaporation of the lowest weight (0/0017). Also, 6/13% of the province has a very high potential and 17/7% of the surface area is completely inappropriate for the disposal of hazardous wastes.Discussion and Conclusion: Study results highlighted the importance and significant weight of environmental criteria in prioritizing the proposed areas for hazardous disposal in Bushehr province, and has shown the model's efficiency in integrating GIS and MCDM.

Moreover waste and chemical substance classification hasbeen done according to RCRA law and Basel convention by considering certain codes for eachsubstance.In general, average produced waste in the study area is estimated about 1750 tones, which means20.4g per each crude oil barrel. Annual average hazardous waste is estimated about 1338.7 tons/year,which is %76.5 of whole produced waste and average amount of non-hazardous waste is %23.5 ofwhole produced waste.According to RCRA classification amongst all substances, only 9 of them have been categorized ashazardous waste listed in K list, 11 substances as hazardous waste from unknown source listed in Flist, 25 substances classified as poisoned hazardous waste listed in U list and 4 substances classified asmajor hazardous have been listed in list P. Generally 49 substances of 133 substances have beenidentified and included in RCRA list.On the other hand according to Basel classification, 14 substances classified by Y codes, 6 substancesby H code and 16 substances goes to both H and Y codes.Results from examinations on soil samples show, that wastes produced by refinery includes heavymetal such as Cd, Co, Cu, Ni and Pb more than standards limits.Soil in Salvage area includes the highest average of Zn, and lowest of Cd.Average density of TPH in regional soil is about 230.58mg per each gram of soil; this clearly showsthe polluted soil with oil-waste in Salvage area Manuscript profile -

According to numerous industrial units, Zanjan province needs aneffective managing method for hazardous wastes. Landfilling is the most common method used tohazardous waste management. Determining of optimum location with considering minimumenvironmental risks and cost effective methods are the scope of this paper. The used method in thispaper is combination of geographic Information System (GIS) and multiple criteria Analysis (MCA).Because of several influencing parameters in landfill site selection, using MCA is necessary. A twosteps method of landfill site was done, including elimination exclusionary areas and calculationsuitability index. In order to determine weights of effective parameters, Analytical Hierarchy Process(AHP) was applied. Simple additive weight method was used for determination of suitability indexand evaluation of study area for hazardous waste landfill. Finally regions with high suitability indexwere suggested for hazardous waste landfills in Zanjan province. Manuscript profile -

The present research addresses the current situation of medical wastes in Golestan province in the North of Iran. This is a descriptive analysis that includes data collection, field survey, and Iranian Department of the Environment (DOE) standard questionnaires for management and monitoring of medical waste in hospitals of the province. The results show that 25 hospitals with 2247 active beds produce 3574 and 2252 domestic and hazardous waste per day, respectively. The waste generation is 2.59 kg/day/bed (1 and 1.59 kg for hazardous and domestic, respectively). Disinfection process in 88% of all hospitals is active and 44% and 52% of the hospitals have done outsourcing, respectively. Disinfection methods include chemical, steam autoclave and dry heat which the second method is the most frequent in most hospitals. Also, 16 hospitals provide monitoring self-reports. The overall situation of medical waste management in the hospitals of Golestan province is average. Considering the change of environmental situation of the country in the future years, the management of this type of wastes should be more serious and it is necessary to design and implement operational programmes for optimum management.

The mismanagement of hazardous waste makes a lot of risks to the human health and the nature considering combustion, reactive, corrosive and toxic characteristics. In order to reduce these side effects the country needs a more comprehensive hazardous waste disposal program (e.g. legislation and regulation). Research Methodology In this study, to overcome these challenges with regard to social - economic conditions and a better commitment by the manufacturers an appropriate legislation has been provided. The purpose of the revision and development of specific regulations for hazardous waste could be described based on the reduce of the severe damage caused by illegal disposal of pollutants into the urban environment as well as filling the existing gaps in state law to preserve nature and the environment. The study also criticized the existing law and administrative regulations of the Waste Management and following a comparison with some of the laws of developed countries, the topics for special legislation for the legal disposal was determined. Results Consisted of 23 articles and 19 notes, as well as a regulatory counterpart including 87 article and 64 notes have been compared. As a result, following a thorough and careful investigation, a piece of legislation In this revised regulations, a special attention is given based on the decrease of production and considering a recycling and reuse program. In addition to the applicable responsibilities, supervision for the implementation of the commitments is considered. This piece of legislation is annually audited by EPA with its divisions. In this regard, there is an especial emphasis by EPA on the private sector for the Waste Management. Site selection is carried out by EPA based on Land Use Planning and Environmental Impact Assessment. However, the Waste Management programs could be done by the private sector as a long contract. To transport and disposal of waste materials by the private sector, a maximum support by EPA has been considered. To reduce of environmental costs, a recycling and reuse program is emphasized. Meanwhile, the producer is responsible for disposal costs. In this proposed piece of legislation, in order to reduce the disposal costs and waste volume, some encouragements have been determined through ISO 14001. In addition, some solutions for business income and updated database are considered by the proposed piece of legislation. Overall, an organized educational program is proposed for public and private sectors. Conclusion This research revealed that to protect the urban environment, a specialized law should be codified. With regard to economic, social, cultural and political situation, a draft law for Waste Management has been developed. The illegal disposal of hazardous waste material is the most important problem in developing countries (e.g. Iran). To address this failure, the Special Waste Management Act and Regulations were presented. The advantages of this new legislation could be described in terms of the establishment of environment, and the view points of citizens on decision making processes the found could provide money for financing the costs associated with environmental recovery, primary evaluation of different legal disposal sites, and study the different environmental aspects for making decision about urgent reaction or improvement actions.
