The external health damage costs of the combined cycle natural gas-fired power plant of Qom were investigated via the simplified impact pathway approach. Emitted particulate matter (PM) and gaseous pollutants (NO , CO, and SO) from the power plant stack were measured The health effects and related costs were estimated by QUERI model from AirPacts according to the emissions, source and stack parameters, pollutant depletion velocities, exposure-response functions, local and regional population density, and detailed meteorological data. The results showed that the main health effect was assigned to the nitrate as restricted activity days (RAD) with 25,240 days/year. For all pollutants, the maximum health damage costs were related to the long-term mortality (49 %), restricted activity days (27 %), and chronic bronchitis (21 %). The annual health damage costs were approximately 4.76 million US$, with the cost being 0.096 US per kWh of generating electricity. Although the health damage costs of gas-fired power plant were lower than those of other heavy fuels, it seems essential to consider the health and environmental damages and focus on the emission control strategies, particularly in site selection for the new power plants and expanding the current ones.
通过简化的影响途径方法，对库姆联合循环天然气发电厂的外部健康损害成本进行了调查。测量了该发电厂烟囱排放的颗粒物（PM）和气态污染物（NO、CO和SO）。根据排放、源和烟囱参数、污染物消耗速度、暴露-反应函数、当地和区域人口密度以及详细的气象数据，采用AirPacts的QUERI模型估算了健康影响和相关成本。结果表明，主要健康影响归因于硝酸盐导致的限制活动天数（RAD），每年为25240天。对于所有污染物，最大的健康损害成本与长期死亡率（49%）、限制活动天数（27%）和慢性支气管炎（21%）有关。年度健康损害成本约为476万美元，每发电千瓦时成本为0.096美元。尽管燃气发电厂的健康损害成本低于其他重质燃料发电厂，但考虑健康和环境损害并关注排放控制策略似乎至关重要，特别是在新发电厂的选址和现有发电厂的扩建方面。
