What are PFAS and the recent PFAS water pollution incident in Japan? PFAS are a type of organic fluorinated compounds that have properties such as water resistance, oil resistance, and heat resistance. They are widely used in various products, such as non-stick cookware, waterproof sprays, and firefighting foams. However, PFAS are also persistent organic pollutants that do not easily break down in nature and can accumulate in soil, groundwater, rivers, plants, animals, and humans, potentially posing health risks. According to research from the Centers for Disease Control and Prevention (CDC), blood levels of PFAS are associated with an increased risk of kidney cancer and testicular cancer. The Stockholm Convention, established by the United Nations, banned the production and use of the two most common PFAS, namely PFOS and PFOA, in 2019. The Japanese government also banned all domestic production and import of PFAS in 2021. However, the pollution problem caused by PFAS remains serious. In Japan, high concentrations of PFAS have been found in rivers and groundwater across the country, with some sources being factories, airports, and U.S. military bases. For example, in Okinawa Prefecture, groundwater near the U.S. Kadena Air Base and the Futenma Marine Corps Air Station was found to contain PFOS at levels exceeding the government’s temporary standard by 110 times. The Okinawa Prefectural Government requested permission from the U.S. side to enter the base for on-site investigation but was denied. In Kanagawa Prefecture, the wastewater treatment facility at the U.S. Yokosuka Naval Base released rainwater containing PFOS in 2022, contaminating nearby streams. In Osaka Prefecture, groundwater and irrigation channels near the Daikin Industries factory were found to contain PFOA at levels exceeding the government’s temporary standard by 130 times. These pollution incidents have raised public concern and protests, demanding that the government and relevant companies take effective response measures.

What are the health risks of PFAS to the human body? This is a good question, as PFAS are chemicals that are widely present in the environment and human bodies, potentially causing adverse health effects. Based on the information I found online, I have compiled the following answers for you:

• PFAS may affect the human immune system, reducing vaccine effectiveness and increasing the risk of infections.

2. They can affect cholesterol levels in the body, increasing the risk of cardiovascular diseases.

3. They can affect the reproductive system, reducing sperm count and fertility.

4. They can affect the endocrine system, interfering with thyroid function and impacting growth and development.

5. They can affect liver function, causing liver damage and impacting metabolism.

6. They can affect kidney function, causing kidney damage and impacting detoxification.

7. They increase the risk of cancer in the body, particularly kidney cancer and testicular cancer.

So, how can we protect ourselves from the dangers of PFAS? Here are a few suggestions:

• Avoid drinking water sources that contain PFAS. If you are unsure about the water quality, you can use activated carbon filters or reverse osmosis systems to remove PFAS.

• Avoid using products that contain PFAS, such as non-stick cookware, waterproof sprays, and firefighting foams. You can choose safer alternatives, such as stainless steel cookware, natural fiber clothing, and water-based firefighting agents.

• Regularly check the PFAS levels in your blood. If they are found to be too high, consult a doctor and take appropriate treatment measures.
