“Forever kimyasallar” onlarca yıldır köpük ve diğer ürünlerle savaşmak için eklendi. (Bigstock Image) Salı günü ABD hükümeti önerilen kurallar Bu, ilk kez içme suyunda “forever kimyasalların” varlığını düzenlerdi.

Düzenlemeler PFAS olarak bilinen tehlikeli kimyasallara uygulanacaktı, “p-fas” diyen per- ve polifloralkyl maddeler için bir acronym. Kimyasallar suyu, lekeleri ve yağları yeniden şekillendirebilir. On yıllar boyunca gıda ambalajına, itfaiyeci köpüklere, halılara ve kumaşlara, su yakalayıcı kıyafetlere ve makyaj panlarına eklenmiştir.

Ama her zaman koymakta değiller. PFAS kirletici İçme suyu içme suyu Washington eyaletinde ve ülkenin çevresinde ve tespit edilmiştir. meme sütü .

ABD Çevre Koruma Ajansı (EPA) kuralları iki PFAS’yi tehlikeli maddeler olarak tasarlayacak, PFAS için içme suyu için izleme ve kirlenmeye ihtiyaç duyacaktır.

Seattle’ın Seattle’ı Toxic-Free Future Kimyasalların kısıtlamaları ve temizlenmesi çağrısına yardımcı oldu. Son zamanlarda üniversite bilim adamlarıyla ortak oldu Çalışma Çalışması Bu, PFAS’yi araştırma için örnek veren tüm 50 anne sütünde buldu.

Araştırmalar, PFAS’ye maruz kalmanın, çocuklarda gelişimsel etkilere veya gecikmelere neden olabileceğini gösteriyor, bazı kanserlerin vakalarını artırdı, bağışıklık yanıtını azalttı ve doğurganlık azaldı.

“Kesinlikle musluktan çıkmamız gerekiyor, bu yüzden artık bu kimyasalları çevreye daha fazla koyuyoruz,” dedi Erika Schreder, daha önce yapılan bir röportajda bilim direktörü.

Seattle-area startup Aquagga Mevcut kirliliği azaltmaya yardımcı olmak için gelişen teknoloji gelişmektedir.

“Bu yeni federal EPA PFAS standartları, ABD’yi PFAS krizine ilişkin önde gelen lideri olarak yakından izleyen dünyadaki endüstri ve ülkeler arasında olumlu bir domino etkisine neden olacaktır,” dedi Aquagga co- kurucu Nigel Sharp e-posta yoluyla.

“Bu zor ama anlaşılabilir ve halk sağlığının [Biden] yönetimi için bir öncelik olduğunu gösteriyor” dedi.

Aquagga’nın teknolojisi bozuluyor ve PFAS’ı yok ediyor. Şirket, Washington Üniversitesi ve Alaska Üniversitesi’nde yapılan araştırma üzerine kuruludur.
