The main purpose of this project is to propose the management suggestions of fluoride air pollutant for ecology, human health, environmental protection standard, and land use planning by collecting and analyzing the control strategies and the related public nuisance disputes of fluoride air pollutant.
According to the finished collecting and analyzing of references, the number of public nuisance disputes and the number of claim people of fluoride-emitting factories are increasing in recent years. As for the main impact of fluoride air pollutant on vegetation is in leaf, which will manifest the symptoms of marginal scorch if the concentration of fluoride exceeds the critical concentration. However, the concentration of fluoride which will transfer to fruit is low. Therefore, the food safety problem of fruit is not the main issue of this project.
For proposing the management suggestions of fluoride air pollutant, this project simulated concentration distribution of fluoride air pollutant which is emitted by fluoride-emitting factories by air quality modeling. The simulation result can be used to define the area of vegetation which was influenced by long term emission of fluoride air pollutant. Furthermore, the defined area can be the arbitration reference of the Committee for Public Nuisance Arbitration.
In addition, the legislation history of the fluoride air pollutant emission standard was analyzed, and the management suggestion was proposed as well in this project according to the past public nuisance disputes. On the other hand, the feasibility of change crop was studied to prevent public nuisance disputes happening. Finally, the possible solution of land use planning problem was also suggested after above discussion.
