Microplastic contamination in Indonesian consumable salts
Microplastics were discovered in sea salts worldwide because they are directly supplied by seawater. This study explores the contamination of five traditionally produced and 10 branded sea salts with microplastics. The highest number of particles was found in the traditionally produced salt (563 items) an abundance of 106.67–3753.33 items/kg. Branded salts had abundance of 25.67 to 866.67 items/kg. There was no significant difference (p > 0.540) in the amount and abundance between these salts. The most predominant shape of microplastics was fiber. The particles sizes ranged from 17 μm to 4.86 mm. The predominant polymers were polyethylene terephthalate and polypropylene. The results indicate both traditionally produced and branded salts are contaminated with microplastics. It is necessary to implement technology to eliminate microplastics from abiotic sea salt to protect health and the environment.
期刊介绍:
The Journal of Sea Research is an international and multidisciplinary periodical on marine research, with an emphasis on the functioning of marine ecosystems in coastal and shelf seas, including intertidal, estuarine and brackish environments. As several subdisciplines add to this aim, manuscripts are welcome from the fields of marine biology, marine chemistry, marine sedimentology and physical oceanography, provided they add to the understanding of ecosystem processes.
