ClearMicroplastic 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.
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.
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 Pollution in Table Salts from China
Researchers analyzed table salts produced in China and found microplastics contaminating samples from multiple salt types, suggesting that salt production processes and source water quality influence the extent of microplastic contamination in a common food ingredient.
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.
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.
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.
“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.
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.
Contamination of Indian sea salts with microplastics and a potential prevention strategy
All eight brands of Indian sea salt tested were found to contain microplastics, with concentrations ranging widely across brands, and the study proposed using improved salt harvesting methods to reduce contamination. The findings add to global evidence of widespread microplastic contamination in commercially sold sea salt, with direct implications for human dietary exposure.
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.
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.
Microplastics in Salt of Tuticorin, Southeast Coast of India
Researchers extracted and characterized microplastics from 14 brands of food-grade sea salts and bore-well salts from Tuticorin, India, finding contamination in both salt types with fibers and fragments as dominant forms and polyethylene as the most common polymer.
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.
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.
High levels of microplastics in commercial salt and industrial salterns in Sri Lanka
All commercial salt products tested in Sri Lanka were contaminated with microplastics, with concentrations ranging from 11 to 193 items/kg in commercial salts and up to 253 items/kg in lab-grade NaCl, and significant variation between three analyzed saltern sites.
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 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.
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.
First-ever study uncovers microplastic contamination in Nepalese table salt
In the first study of its kind in Nepal, researchers found microplastics in 100% of table salt samples tested from across the country, with levels ranging from 80 to 1,040 particles per kilogram. The most common shapes were fibers and films made of polyethylene, polypropylene, and nylon. Since salt is consumed daily by nearly everyone, this represents a consistent source of microplastic ingestion for the Nepalese population.
