Many microplastics in the world's oceans have likely escaped detection, researchers say

Chemicals within microplastics that are found in our world's oceans and waterways, and in drinking water sources, remain of concern to scientists and public health officials. A new study that investigated the presence of the smallest particles of microplastics (MPs) in ocean waters from the Caribbean to the Arctic found that the most abundant (and tiny) MPs in the ocean are not being detected by net tow surveys.
