ClearEvaluation 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.
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.
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.
Extraction of microplastics from commonly used sea salts in India and their toxicological evaluation
Scientists extracted and characterized microplastics from commercial sea salts sold in India, finding contamination across brands and conducting toxicological tests showing potential harm to marine organisms.
Risk assessment of microplastic in commercial salt sold in Malaysia
Researchers conducted a risk assessment of microplastics in commercial table salt sold in Malaysia, finding that contaminated seawater used during sea salt production introduces microplastics into a widely consumed daily food ingredient with potential adverse health effects.
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.
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.
Nanoplastics Detected in Commercial Sea Salt
Researchers detected nanoplastic particles in commercial sea salt samples using advanced analytical techniques, demonstrating that a widely consumed everyday food product is contaminated with plastic nanoparticles derived from ocean and atmospheric pollution. The findings raise concerns about dietary nanoplastic exposure for people of all ages through routine salt consumption.
Microplastics in Spanish Table Salt
This study analyzed samples of commercially sold Spanish table salt and found microplastics in some products, adding to a growing body of evidence that sea-derived food products are contaminated with plastic particles. The results underscore the difficulty of avoiding microplastic exposure in everyday foods.
Litter & microplastics features in table salts from marine origin: Italian versus Croatian brands
Researchers analyzed microplastic content in marine-origin table salts from Italian and Croatian commercial brands, finding microplastic contamination in all tested products with no macroplastic or mesoplastic particles recovered, and characterizing the size, shape, and polymer types present.
Contamination of table salts from Turkey with microplastics Part A Chemistry, analysis, control, exposure & risk assessment
This study analyzed 16 brands of table salt from Turkish markets and found microplastics in most samples, with concentration varying by salt type and source. The findings add to growing global evidence that microplastics have entered the human food chain through commercial sea and lake salt.
Microplastic contamination of salt intended for human consumption: a systematic review and meta-analysis
This systematic review and meta-analysis examined microplastic contamination in table salt from around the world. It found that microplastics are present in most salt products intended for human consumption, with sea salt generally containing more particles than rock or lake salt, representing a consistent source of dietary microplastic exposure.
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.
Microplastic contamination in commercial salt: An issue for their sampling and quantification
Researchers analyzed microplastic contamination in commercial sea salt from three Italian salterns and found an average of approximately 1,653 microplastic particles per kilogram of salt. The study highlights important methodological considerations for sampling and quantification, noting that the physical characteristics and polymer types of microplastics varied across sampling locations.
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.
Contamination of table salts from Turkey with microplastics
Sixteen brands of table salt sold in Turkish markets — including sea, lake, and rock salts — were found to contain microplastics, with the highest concentrations in sea salt. The study adds to global evidence of microplastic contamination in commercially sold salt and indicates widespread human dietary exposure through this common food ingredient.
“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.
