Detection and Characterization of Microplastics in Commercial Salts in India

Researchers detected and characterized microplastics in commercial salts available in India, including rock salt, sea salt, and table salt varieties. The study found widespread microplastic contamination across salt types, raising food safety concerns given the ubiquity of salt as a dietary staple.

Assessment of microplastics in edible salts from solar saltpans and commercial salts

Researchers analyzed microplastic contamination in sea salts from solar salt pans in Tamil Nadu, India, and several commercial salt brands. The study confirmed the presence of microplastics in all salt pan samples and two commercial salt brands, with fewer than 350 polymer fragments per sample representing multiple polymer types. These findings suggest that sea salt production is a pathway for microplastic contamination to reach human diets.

Microplastic contamination in Indonesian consumable salts

Researchers analyzed both traditionally produced and commercial branded sea salts from Indonesia and found microplastics in all samples tested. Traditionally produced salts contained the highest contamination levels, with up to 3,753 particles per kilogram, though branded salts also contained significant amounts. The study indicates that sea salt is a notable dietary source of microplastic exposure for consumers.

Microplastic presence in commercial marine sea salts: A baseline study along Tuticorin Coastal salt pan stations, Gulf of Mannar, South India

Twenty-five sea salt samples from Tuticorin coastal salt pans in India were analyzed for microplastics, with particles under 100 μm comprising 60% of contaminants and polypropylene and polyethylene as the dominant polymers. The study establishes a baseline for microplastic contamination in commercially harvested sea salt from South India.

“Microplastic seasoning”: A study on microplastic contamination of sea salts in Bangladesh

Researchers tested 18 brands of commercial sea salt from Bangladesh and found microplastics present in every sample, with an average of about 472 particles per kilogram. The study suggests that sea salt represents a dietary pathway for human microplastic exposure, with fibers and fragments being the most commonly detected particle types.

Global Pattern of Microplastics (MPs) in Commercial Food-Grade Salts: Sea Salt as an Indicator of Seawater MP Pollution

A global analysis of commercial sea salts found microplastics in samples from 21 countries, with the highest concentrations in sea salts from Asia and the lowest in rock and lake salts. The findings suggest that sea salt can serve as an indicator of seawater microplastic pollution levels in surrounding regions.
