It is with great pleasure that I invite you to the Asian Symposium on Contamination Control 2025, which will be held in the vibrant city of Seoul from Oct 23 to 24, 2025 at COEX. This symposium will mark a significant milestone in our collective efforts to address and mitigate contamination challenges across various industries.

Through previous ASCC in Shanghai (2019) and Kanazawa (2023), we have been reminded of the critical importance of contamination control in ensuring the safety, quality, and sustainability of our environments and products. Following the tradition, I believe that ASCC 2025 will provide a unique platform for experts, researchers, and practitioners from around the world to share their knowledge, innovations, and best practices. During the symposium, we will engage in insightful discussions, explore cutting-edge technologies, and foster collaborations that will drive advancements in our field. I encourage you to take full advantage of the diverse sessions, workshops, and networking opportunities that will be meticulously planned.

Seoul, with its rich cultural heritage and modern dynamism, offers an inspiring backdrop for our symposium. I hope you will also find time to experience the city’s unique blend of tradition and innovation.
