Noorian Najafabadi, S.A. (author), Ding, Er (author), Hobeika, N. (author), Bluyssen, P.M. (author)Indoor air quality (IAQ) is an important aspect of maintaining human health and well-being, particularly since people spend most of their time indoors. Carpets, with their large surface area and dense fibre piles, have the potential to significantly impact IAQ by emitting and absorbing volatile organic compounds (VOC) from building materials and...journal article 2024
