Per- and polyfluoroalkyl substances (PFAS), commonly known as "forever chemicals," are persistent synthetic compounds that have been widely utilized since the mid-20th century across various industries. Due to their environmental persistence and potential health risks, PFAS has become a significant concern, particularly in relation to water and wastewater contamination. This paper investigates the complex challenges associated with PFAS, focusing on existing regulatory frameworks, treatment strategies, and innovative clean technologies that aim to reduce or eliminate these harmful substances. The study emphasizes the importance of advanced treatment methods such as electrochemical degradation, nanofiltration, adsorption, and biodegradation, each offering varying degrees of success. Despite advancements in treatment technologies, prevention remains the most effective strategy to minimize PFAS pollution. The paper calls for collaborative efforts from regulatory bodies, industries, and communities to implement more sustainable practices, ensuring a toxic-free environment and aligning with circular economy principles. Continuous research and international cooperation are crucial for developing effective long-term solutions to address PFAS contamination and safeguard both public health and the environment.

Toksik Madde-Fre Serbest Ortam: Suyun ve Atıksuların Sonsuz Kimyasallardan Arındırılması

Öz

Per- ve polifluoroalkil maddeler (PFAS), yaygın olarak "sonsuz kimyasallar" olarak bilinen, 20. yüzyılın ortalarından itibaren çeşitli endüstrilerde geniş çapta kullanılan kalıcı sentetik bileşiklerdir. Çevresel kalıcılıkları ve potansiyel sağlık riskleri nedeniyle, PFAS özellikle su ve atık su kirliliğiyle ilgili olarak önemli bir endişe kaynağı haline gelmiştir. Bu makale, mevcut düzenleyici çerçeveler, arıtma stratejileri ve bu zararlı maddeleri azaltmayı veya ortadan kaldırmayı hedefleyen yenilikçi temiz teknolojiler üzerine odaklanarak PFAS ile ilgili karmaşık zorlukları incelemektedir. Çalışma, elektrokimyasal bozunma, nanofiltrasyon, adsorpsiyon ve biyolojik bozunma gibi gelişmiş arıtma yöntemlerinin önemini vurgulamaktadır ve her birinin farklı derecelerde başarı sunduğunu ortaya koymaktadır. Arıtma teknolojilerindeki ilerlemelere rağmen, PFAS kirliliğini en aza indirmek için en etkili strateji, önleme olmaya devam etmektedir. Makale, toksik olmayan bir çevrenin sağlanması ve döngüsel ekonomi ilkeleriyle uyumlu daha sürdürülebilir uygulamaların hayata geçirilmesi için düzenleyici organlar, sanayi ve toplulukların ortak çabalarını gerektirdiğini belirtmektedir. PFAS kirliliğini ele almak ve hem halk sağlığını hem de çevreyi korumak için etkili uzun vadeli çözümler geliştirmek adına sürekli araştırma ve uluslararası iş birliği kritik öneme sahiptir.

Anahtar Kelimeler
