Microplastic debris floating at the ocean surface can harm marine life. Understanding the severity of this harm requires knowledge of plastic abundance and distributions. Dozens of expeditions measuring microplastics have been carried out since the 1970s, but they ha...ve primarily focused on the North Atlantic and North Pacific accumulation zones, with much sparser coverage elsewhere. Here, we use the largest dataset of microplastic measurements assembled to date to assess the confidence we can have in global estimates of microplastic abundance and mass. We use a rigorous statistical framework to standardize a global dataset of plastic marine debris measured using surface-trawling plankton nets and coupled this with three different ocean circulation models to spatially interpolate the observations. Our estimates show that the accumulated number of microplastic particles in 2014 ranges from 15 to 51 trillion particles, weighing between 93 and 236 thousand metric tons, which is only approximately 1% of global plastic waste estimated to enter the ocean in the year 2010. These estimates are larger than previous global estimates, but vary widely because the scarcity of data in most of the world ocean, differences in model formulations, and fundamental knowledge gaps in the sources, transformations and fates of microplastics in the ocean.

he WHO global disability action plan 2014-2021 is a significant step towards achieving health and well-being and human rights for people with disabilities. The action plan was endorsed by WHO Member States in 2014 and calls for them to remove barriers and improve access to health services and progra...mmes; strengthen and extend rehabilitation, assistive devices and support services, and community-based rehabilitation; and enhance collection of relevant and internationally comparable data on disability, and research on disability and related services. Achieving the objectives of the action plan better enables people with disabilities to fulfil their aspirations in all aspects of life.
