It is also widely used in household and industrial cleaning products. Recent studies found that PFOS does not degrade and is leading to bioaccumulation in our environment and food chains. The oral Median Lethal Dose (LD50) of PFOS for rats is 251 mg/kg and the inhalation Median Lethal Concentration (LC50) is 5.2 mg/l/1 hr. The World Health Organization (WHO) has classified PFOS as the median-level toxic substance. The United States Environmental Protection Agency (US EPA) also puts PFOS in their chemical list of Persistent Organic Pollutants (POPs) in 2001 and implements strict management of its use and production.
This research adapted the study methods of systematic thought and approach to consider different aspects from economy, environment and environmental education, to consider individuals, enterprises and government as the main body of management, and to plan and design effective control system and strategy. The results will be used as a reference to provide the government to draw up the correlation policy.
For the source management of PFOS, the Environmental Protection Administration (EPA), the Ministry of Economic Affairs (MEA), and local governments will be in charge of supervision. The EPA and the Department of Health (DOH) will have the responsibility of monitoring and creating environment database of the distribution of PFOS in the environment. The legal system and examination methods of PFOS will be established after reaching agreement between EPA and other competent authorities. Regarding the notification system, the DOH, MEA, and the Council of Agriculture are responsible for coordinating with EPA to handle accidents and prevent possible harm. Through conducting special projects and phases, monitoring of environmental quality, and overseeing by non-governmental organizations the management system and strategy can be evaluated.
