ClearEvaluation of vertical distribution characteristics of microplastics under 20 μm in lake and river waters in South Korea
Brazilian researchers developed a cost-effective optical microscopy method using Bengal Rose dye to identify microplastics in commercial table salt, finding contamination in all six brands tested — including an analytical-grade salt — at levels ranging from 33 to 236 particles per kilogram. Fibers accounted for 63% of particles found, with fragments making up the rest. The study confirms that everyday food staples are a route of microplastic ingestion and provides a practical, affordable screening method for low-resource settings.
Microparticles in Table Salt: Levels and Chemical Composition of the Smallest Dimensional Fraction
Analysis of commercially available table salts found microplastic particles and non-synthetic micro-particles in multiple brands, with the smallest size fractions being most abundant and most difficult to identify. The study raises concerns about human dietary exposure to microplastics through a universally consumed food product.
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.
Consuming microplastics? Investigation of commercial salts as a source of microplastics (MPs) in diet
Researchers analyzed various commercial Australian salts, including both marine and terrestrial varieties, for microplastic contamination. The study detected microplastics in all salt samples tested, including the first detection in black salt, indicating that commercial table salt is a potential dietary source of microplastic exposure for humans.
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.
Detection and Characterisation of Microplastics in Food Grade Salts in India
Researchers analyzed 30 brands of food-grade salt available in India and found microplastics in all samples, with sea salt containing 13 to 27 particles per 100 grams and rock salt containing 8 to 29 particles per 100 grams. Particle sizes ranged from about 19 to 1,433 micrometers, and polyethylene terephthalate (PET) was the most commonly identified polymer. The study suggests that salt is a routine dietary source of microplastic exposure for consumers.
Microplastic contamination and risk assessment in salts from India And Sri Lanka
Researchers analyzed microplastic contamination in commonly available salts from India and Sri Lanka, including sea salt, rock salt, and refined table salt. Microplastics were detected across most salt varieties, indicating that this staple condiment is a dietary route of human microplastic exposure in South Asia.
Evaluation of the presence of insoluble particles and microplastics in sea salts in Brazil
Researchers analyzed sea salts from Brazilian markets for the presence of microplastics and other insoluble particles. The detection of microplastics in commercially sold sea salt raises consumer exposure concerns, as salt is used universally in cooking and food processing.
Detection of microplastic contamination in table salts in Padang City, Indonesia, and control strategies for choosing healthy salt
Researchers analyzed microplastic contamination in ten brands of table salt commonly consumed in Padang, Indonesia. The study found microplastic particles in all brands tested, ranging from 30 to 510 particles per kilogram, with fragments being the most common shape, suggesting that salt products represent a meaningful source of dietary microplastic exposure.
Evaluation of salt intended for human consumption for the presence of physical contaminants: microplastics an emerging contaminant in the food area
Researchers analyzed eight salt samples sold in Rio de Janeiro supermarkets and found physical contaminants consistent with microplastics in five of them, suggesting oceanic microplastic contamination is reaching consumers through table salt and underscoring the need for food quality monitoring programs.
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 pollution in commercial salt for human consumption: A review
This review examines microplastic contamination in commercial table salt from 128 brands across 38 countries on five continents. Researchers found that while microplastic concentrations in salt are lower than in some other food products like mussels, salt represents a significant long-term daily exposure route for the general population. The study highlights that commercial salt contaminated with microplastics may contribute to cumulative human exposure alongside other dietary and environmental sources.
The presence of microplastics in commercial salts from different countries
Researchers analyzed 17 commercial salt brands from eight countries and found microplastic particles in all but one, with concentrations ranging from 1 to 10 particles per kilogram. The most common plastics were polypropylene and polyethylene, appearing mainly as fragments. While the estimated human intake from salt alone appears minimal, the study confirms that microplastics have infiltrated yet another everyday food product.
Microplastic contamination in table salt sold in the selected local markets inSamar, Philippines
Researchers tested for microplastic contamination in commercial table salt sold in local markets in Samar, Philippines, a seafood-dependent region where marine microplastic contamination is a direct food safety concern. Microplastics were detected in salt samples, confirming that this widely consumed condiment is a pathway for human microplastic ingestion in Philippine communities.
