Scientists identify a new source of air pollution - tiny shreds of microplastic
(WorldNews Environment)

Scientists who sampled seemingly pristine Arctic snow have discovered high levels of microplastics that were likely carried north by the atmosphere. The discovery, published in the journal Science Advances, points to an unexpectedly high source of microplastics in one of the most remote and pristine regions of Earth. It also raises troubling questions about the environmental and health implications of potential exposure to such airborne plastics. `I was really astonished concerning the high concentrations,` said senior author Gunnar Gerdts, a marine microbiologist at the Alfred Wegener Institute in Germany. Some 380 million metric tons of plastic are produced each year. Much of that plastic...
