Background and Aim: Medical waste is one of the most important environmental issues which have the dangerous factors. Planning of medical waste management is necessary to prevent waste from adverse effects on human and environmental health. The objectives of this study were to determine the quantity of different types of medical waste and waste management in Razi hospital of Torbat-e-Hey...
active carbons were produced from bagasse, millet and sorghum straws by chemical activation with h3po4. carbon precursors with particle size of 1180 î¼m were used, in order to overcome difficulties caused by low density and high ash content. the influence of preparation conditions (temperature, residence time, and acid impregnation ratio) on the yield of the active carbons was examined. the imp...
هدف از این تحقیق این است که با در نظر گرفتن ملاحظات زیست محیطی و فنی – مهندسی، مناطق مطلوب برای دفن پسمانهای اتمی تعیین شود. در این تحقیق سعی شده با استفاده از سامانه اطلاعات جغرافیایی و با بهرهگیری از لایههای اطلاعاتی زمینشناسی، لرزهخیزی، خاکشناسی، هیدرولوژی و هیدروژئولوژی، شیب، کاربری اراضی، گسل، پوشش گیاهی، مناطق مسکونی و صنعتی، خطوط ارتباطی، مناطق چهارگانه محیط زیستی و با توجه به شرای...
Background and Objectives: Uncontrolled disposal of dangerous industrial waste can cause irreversible environmental problems due to contamination of soil, groundwater and surface water. In order to avoid these problems, this study aimed to assess the functional elements in industrial solid waste management systems in active plants located in the industrial plants of Rafsanjan. Materials and...
Background and Aim: Hospital wastes are considered hazardous wastes due to their potential impact on environmental pollution and health hazards. The aim of this study was to determine the quantitative status of hospital wastes in selected hospitals of the Armed Forces in Iran and examine the adaptability of the current waste management practice with the fourth-generation accreditation model. Me...
An outdoor pilot-scale study was undertaken to pretreat municipal solid waste by windrow composting. The raw waste was introduced to active composting without any source separation or pulverization. Pretreatment indicators were developed and used as a tool to measure the optimum level of sorting and waste stabilization. The moisture content of the waste dropped from 68% to 61% and the pile atta...
Background and Aims: In the last decades, hazardous wastes have been one of the most important issues resulted from industries progress. Improper transport of hazardous waste has created many problems for human health and the environment. Therefore it is necessary to adopt management plan for disposal of waste materials. Regarding our country pollution control plan needs to be advanced in par...
A simple theoretical model was developed to assess the contribution of the pathogens and group D pharmaceutically active waste to the toxicity of the fire plume from an accidental fire in the stored material. The method was applied to stored waste at an authorised incinerator site and the study showed the additional hazard of the pathogen biohazard and pharmaceutically active material to be neg...
