How much do you know about PFASs?

1. What are PFASs

Perfluorinated/polyfluoroalkyl substances (PFASs) are a large group of chemically synthesized substances, with thousands of species, and they have unique physical and chemical properties, so they are widely used. They are chemically stable and waterproof, oil-proof, Substances with low friction; also because of their stable characteristics, they cannot be naturally decomposed and exist for a long time in the environment, becoming persistent organic pollutants. The copy rolex for sale online here are at affordable prices.

2. What items may contain PFASs?

Some of the major industries that use PFASs include aerospace, defense, automotive, textiles, construction, electronic appliances, firefighting, food, medical, etc.

Among them, the largest production is Perflurooctane sulfonic acid (PFOS) and Perflurooctanoic acid (PFOA). In the process of producing Teflon (polytetrafluoroethylene) materials, PFASs such as PFOA or PFOS need to be added as additives, and there will be some residues in the final Teflon product. Existing toxicological studies have shown that a certain dose of PFASs can cause liver toxicity, developmental and reproductive toxicity, genetic and immunotoxicity, and carcinogenicity in laboratory animals. Buy best 1:1 super clone watches online.

3. Is there a risk of PFASs contamination in food?

Although the very stable characteristics of PFASs have brought many applications, they are not easily decomposed by nature. They are highly persistent in the environment. During the production of PFASs, they may pollute nearby environments, such as drinking water and soil, and enter organisms. Contaminated plants in the ecological chain. In addition to environmental and water pollution, food contact materials may also be the source of PFASs, such as popcorn bags, pizza boxes, Teflon non-stick pans, etc. At present, countries around the world are still continuously evaluating the impact of such compounds on human health, and have issued a series of regulations and policies.

4. Local regulations and requirements:

The State of California in the United States has proposed a bill (AB 958) to ban products containing certain perfluoroalkyl or polyfluoroalkyl substances (PFASs), and requires the Department of Toxic Substances Control (DTSC) to consider foods containing PFASs Contact materials as potential priority products. Chapter 6.5 of Part 20 of the "Health and Safety Code" proposes to add the following requirements:

On March 21, 2018, the Governor of Washington State signed Act HB2658 to restrict the use of perfluoroalkyl and polyfluoroalkyl substances (PFASs) chemicals in food packaging. From January 1, 2022, it is prohibited to sell in Washington State, provide the sale or distribution of food packaging intentionally added PFASs chemical substances. All best models of uk perfect super clone watches online can be find here.

The international "Stockholm Convention" lists PFASs as persistent organic pollutants. The European Union also restricts regular monitoring of this compound. In addition to continuous monitoring and assessment of health effects, the US Environmental Protection Agency has also formulated Health advisory levels in drinking water (Health advisory levels) It is 70 ppt, and the PFOS and PFOA gradual reduction plan is formulated together with the industry.

Denmark promulgated Decree No. 681 of May 25, 2020, "Administrative Orders and Penalties on Food Contact Materials Violating Related European Acts", prohibiting the use of PFASs in food contact paper and cardboard materials and articles, and in July 2020 Officially entered into force.

On May 11, 2020, according to the official website of the European Chemicals Agency ECHA, the competent authorities of the 5 EU member states (Germany, Netherlands, Norway, Sweden and Denmark) have agreed to formulate a REACH regulation joint restriction proposal to restrict PFASs The production and use of PFASs, thereby reducing the harm caused by PFASs to the environment and human health.

On July 9, 2020, the Toxicsin Packaging Clearinghouse (TPCH) website in the United States issued a public statement to solicit comments on the updated draft of the Toxicsin Packaging Model Legislation. The draft involves the addition of perfluoro/polyfluoroalkyls (PFASs) and phthalates as controlled substances, and also proposes some new procedures for verifying high-risk chemical substances in packaging materials.
