在化工厂开发设计的初期阶段，化工工艺路线的选择是关键的设计决策。在过去，经济性是选择化工工艺路线的最重要标准。安全和环境问题已成为重要的考虑因素。缺乏评估化学工艺路线对环境友好性的方法。环境危害指数（EHI）根据化学品库存总量释放的估计环境影响对路线进行排名。EHI是化学品的环境影响的函数，以及如果设计和建造，将实施路线的工厂中的估计库存。EHI越低，路线就越环保。EHI已在六种潜在的和已建立的甲基丙烯酸甲酯（MMA）路线上进行了测试。这些结果已与相同的化学工艺路线的固有安全指数进行了比较。一个表达式已被推导出EHI与估计的鱼类死亡。
At the preliminary stages of chemical plant development and design the choice of the chemical process route is the key design decision. In the past, economics were the most important criterion in choosing the chemical process route. Safety and environmental issues have now become important considerations. Methods are lacking for assessing chemical process routes for environmental friendliness. The Environmental Hazard Index (EHI) ranks routes by the estimated environmental impact of a total release of chemical inventory. The EHI is a function of the environmental effects of the chemicals and the estimated inventory thereof in a plant that, if designed and built, would implement the route. The lower the EHI the more environmentally friendly is the route. The EHI has been tested on six potential and established routes to Methyl Methacrylate (MMA). These results have been compared with those for the Inherent Safety Index for the same chemical process routes. An expression has been derived which relates the EHI to an estimated fish kill.
