Groundbreaking environmental and health studies reveal pervasive micro- and nanoplastics across terrestrial and aquatic ecosystems, human feces, and bloodstreams, raising alarming possibilities for chronic health effects. Innovative methodologies leveraging AI, spectroscopy, and advanced sampling techniques improve microplastic detection and assessment, highlighting urgent needs for improved monitoring and regulatory frameworks. These findings echoed in reports by The Lancet and other institutions emphasize plastic pollution as an escalating global health and ecological crisis demanding comprehensive scientific and policy responses.
