Microplastics on table salt. Tiny fragments and filaments of plastic inside and among cuisine salt crystals photographed with 5x enlargement. Polyester microfibres. The presence of microplastics in the seawater has been revealed as hazardous. Three possible toxic effects of plastic particle have been indicated: first due to the plastic particles themselves, second to the release of persistent organic pollutant (POPs) adsorbed to the plastics and third to the leaching of additives of the plastics. We are eating plastic particles every day indirectly by ingesting contaminated marine animals and directly through the cooking salt with which we season the food. Saline salt collected from the west coast of Portugal.
