Abstract

The development of health services of hospitals in developing countries has led to a significant increase in the production of infectious waste, which has important economic and environmental consequences. Therefore, reducing pollutant leakage caused by disinfection and reducing infectious waste management costs are important in achieving sustainable development goals in hospital management. In this study, the centralized and decentralized patterns of infectious waste management were studied in three hospitals in Behbahan, Iran. Economic analysis was done based on the financial model. Phthalate emission from disinfection equipment was measured for investigating the level of exposure to the pollutant in the studied patterns. The results showed that the cost of waste transportation for studied hospitals in the centralized patterns increased by 12.1 %. However, reductions in disinfection and transfer costs up to 32.4 % were available by increasing the segregation ratio of infectious waste. The average emission of phthalates from disinfection equipment in the studied hospitals was 0.260 ng/kg. But emission of phthalate types was not the same, so that the emission of BEHP, IBP, and DBP was 35.97, 4.90, and 1.55 μg/m³, respectively. Considering the hospital waste reduction plan and increasing the segregation ratio to reduce the costs of the hospital led to economic justification of the centralized pattern of infectious waste management as a safe option.

研究集中式和分散式感染性废物管理模式造成的经济后果和邻苯二甲酸盐排放。

发展中国家医院卫生服务的发展导致感染性废物的产生量大幅增加，对经济和环境产生了重要影响。因此，减少消毒造成的污染物泄漏，降低感染性废物管理成本，对于实现医院管理的可持续发展目标具有重要意义。本研究对伊朗贝赫巴汉市三家医院的集中式和分散式感染性废物管理模式进行了研究。根据财务模型进行了经济分析。测量了消毒设备排放的邻苯二甲酸盐，以调查所研究模式中污染物的暴露水平。结果表明，所研究的医院在集中模式下的废物运输成本增加了 12.1%。不过，通过提高感染性废物的隔离率，消毒和转移成本可降低 32.4%。研究医院消毒设备的邻苯二甲酸盐平均排放量为 0.260 纳克/千克。但邻苯二甲酸盐类型的排放量并不相同，因此 BEHP、IBP 和 DBP 的排放量分别为 35.97、4.90 和 1.55 μg/m3 。考虑到医院的废物减量计划和提高分类率以降低医院成本，传染性废物集中管理模式作为一种安全的选择在经济上是合理的。
