ClearMicroplastic 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.
Microplastics in Table Salts: Sources, Abundance, Types, and Consumption– A Review
This global review synthesizes research on microplastic contamination in table salts, examining sources, abundance, particle types, and estimated human consumption, finding that sea salts tend to have higher microplastic loads than rock or lake salts.
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.
Microplastics in European sea salts – An example of exposure through consumer choice and of interstudy methodological discrepancies
Researchers analyzed 13 European sea salts and found microplastics in all of them, with industrially harvested salts containing more particles than traditionally harvested ones. They estimated that a person absorbs about 14 micrograms of microplastics annually from all salt consumption, with a quarter attributable to choosing sea salt specifically. The study also found that differences in research methods across studies make it difficult to compare microplastic levels in salt worldwide.
Quantifying ecological risks of aquatic micro- and nanoplastic
This study analyzed microplastic contamination in table salts from multiple countries and found plastic particles present in the vast majority of samples tested. Sea salt contained the highest levels of microplastics compared to rock and lake salts, reflecting the extent of marine plastic pollution. The findings suggest that table salt is a previously underappreciated pathway for human microplastic ingestion, with estimated annual intake varying by geographic region.
Microplastic Contamination in Common Salt from Seawater
This book chapter examines microplastic contamination of sea salt produced from evaporation of seawater, reviewing evidence that salt from multiple countries contains MPs and discussing the human dietary exposure implications of consuming salt with plastic particle contaminants.
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.
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 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.
Microplastic contamination in edible sea salt from the largest salt-producing states of India
Microplastics were found in edible sea salt samples from the major salt-producing states of India, with crystal salt containing lower concentrations than powdered salt, and fibers and fragments as the dominant types, confirming that sea salt is a source of human dietary microplastic exposure in South Asia.
Microplastic contamination of table salts from Taiwan, including a global review
Researchers analyzed table salt products sold in Taiwan for microplastic contamination and detected an average of nearly 10 microplastic particles per kilogram of salt. Polypropylene and polyethylene were the most commonly identified polymer types. The study includes a global comparison showing that microplastic contamination of table salt is a widespread phenomenon, representing a consistent low-level dietary exposure pathway for consumers.
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.
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.
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.
