Excerpts;

Although the fates of microplastics (0.1–5 mm in size) and nanoplastics (<100 nm) in marine environments are being increasingly well studied, little is known about the behaviour of nanoplastics in terrestrial environments, especially agricultural soils.

The latest findings provide direct evidence that nanoplastics can accumulate in plants, depending on their surface charge. Plant accumulation of nanoplastics can have both direct ecological effects and implications for agricultural sustainability and food safety…

Americans Consume Tens of Thousands of Microplastic Particles Every Year; Yale E360 (06-05-2019)
Americans consume more than 70,000 microplastic particles every year from the food they eat, the water they drink, and the air they breathe, according to a new study published in the journal Environmental Science & Technology. Scientists warn that while the health impacts of ingesting these tiny particles are largely unknown, there is potential for the plastic to enter human tissues and cause an immune response, as well as release toxic chemicals into the body…

Video captures moment plastic enters food chain, BBC News (03-11-2017)
A scientist has filmed the moment plastic microfibre is ingested by plankton, illustrating how the material is affecting life beneath the waves. The footage shows one way that plastic waste could be entering the marine and global food chain…

Plastic pollution: When The Mermaids Cry: The Great Plastic Tide, Coastal Care
Plastic is versatile, lightweight, flexible, moisture resistant, strong, and relatively inexpensive. Those are the attractive qualities that lead us, around the world, to such a voracious appetite and over-consumption of plastic goods. However, durable and very slow to degrade, plastic materials that are used in the production of so many products all, ultimately, become waste with staying power. Our tremendous attraction to plastic, coupled with an undeniable behavioral propensity of increasingly over-consuming, discarding, littering and thus polluting, has become a combination of lethal nature…
