A review by IIT Madras has highlighted residential buildings as a major source of microplastic pollution. The study explores the impact of microplastics on aquatic organisms and humans, addressing issues related to transportation, transformation, and toxicity effects. The authors emphasize that this is the first attempt to identify diverse activities and products within residential buildings as significant contributors to microplastic generation. The findings shed light on the need for increased awareness and management strategies to mitigate the impact of microplastics on the environment and human health.
