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.

Methodological field approaches for scientists with a basic background in entomology to prepare and implement a yellow fever entomological assessment during outbreaks
WHO has been alerted to concerns expressed related to the wording on episiotomy in specific situations. We have temporarily removed the publication from the website while we are doing a review of the evidence with in-house and external experts. We will make the publication available on the website o...nce the review is completed and any needed revisions are made. Please check the website!!!

This paper is therefore designed to review public knowledge and belief about mental disorders (mental health literacy) in developing countries with particular emphasis on the public knowledge and beliefs about causes and symptoms of mental dis...orders, public attitude and perception towards people with mental illness and help seeking behaviors. The review will provide important evidences from developing countries which are relevant to introduce the concept of mental health literacy in Ethiopia as there has been no systemic review of evidences on mental health literacy and to guide the development and implementation of a mental health policy in Ethiopia where mental health policy is absent
