Three quarters of soils in France contaminated with microplastics

,
A study by the Agency for Ecological Transition reveals that 76 percent of soils examined contain microplastics between 0.3 and 5 millimeters in size. Polyethylene is the most prevalent polymer
Tra i bioprodotti, i teli pacciamanti sono tra quelli i cui vantaggi sono più tangibili: diversamente da quelli prodotti in plastica fossile, a fine coltura si possono incorporare nel terreno con una semplice trinciatura e non hanno costi di lavaggio, rimozione e smaltimento.

‘Biodegradable plastics do not impact ecosystems’

Forests keep us from breathing in microplastics

,
Airborne microplastics latch onto tree leaves, explains a Japanese study. In this way, forests act as sinks thereby limiting their uptake by humans
