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.

It provides guidance on care for use in resource-limited settings or in settings where families with sick young infants do not accept or cannot access referral care, but can be managed in outpatient settings by an appropriately trained health worker. The guideline seeks to provide programmatic guida...nce on the role of CHWs and home visits in identifying signs of serious infections in neonates and young infants.

This module aims to provide basic guidance on management of range of mental health complaints not coveredelsewhere in this guide. Some of these complaints may be similar to depression, but upon closer examamination are distinct from the conditions covered in this guide. Other mental health complaint...s are considered significant when they impair daily functioning or when the person seeks help for them. Other mental health complaints can be due to stress.
