Screw caps a source of microplastics

Scientists find increased release of microplastic particles after repeated open/close cycles in screw-cap plastic bottles, no release from bottle walls; call for more research on degradation of food contact plastics

Letter urges EU ministers to reject microplastics restriction

34 NGOs and alliances recommend environment ministers reject ECHA’s current proposed restriction on microplastics, cite concerns over exceptions included for biodegradable microplastics and exceptionally long transition periods

Plastic Health Summit talks published

Event brings together scientists and advocates to discuss latest research on micro- and nanoplastics, plastic additives, and health; presentations recorded and now publicly available

Recommendations for improving microplastics research

Marine biologist criticizes inconsistencies and unrealistic techniques used to study microplastic pollution; recommends avoiding nets for sampling, microscopes for counting; promotes using non-spherical microplastics and allowing time for elimination; researchers should focus on quality over quantity

Study finds microplastics harm immune cells

Researchers at University Medical Center Utrecht observe that immune cell death rate triples after contact with microplastics; presents results at Plastic Health Summit in Amsterdam on October 3, 2019

Plastic tea bags release billions of particles

Researchers measure micro- and nanoplastics released from plastic tea bags during brewing; find over 14 billion particles released per bag, record dose-dependent behavioral and developmental effects on daphnia

Overview article on microplastics in fish

WHO report on microplastics in drinking water

Microplastics do not currently pose human health risk in drinking water according to World Health Organization; studies however seen as limited and often unreliable; calls for standardization of analysis methods and minimization of plastic pollution
