ClearInvestigating the Correlation of Microplastic Pollution Between Seawater and Marine Salt Using Micro-Raman Spectroscopy
Micro-Raman spectroscopy was used to investigate the correlation between microplastic contamination in seawater and marine salt from the same source waters, finding that the polymer profiles of microplastics in salt broadly reflect those in the seawater from which the salt was produced.
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.
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 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.
An investigation on the prevalence of microplastic in commercial and open pan salts obtained from Cox's Bazar and Maheshkhali region of Bay of Bengal (Bangladesh)
Researchers found microplastics in all commercial and open pan salt samples from the Cox's Bazar and Maheshkhali regions of Bangladesh, identifying polyethylene, PET, and other polymers through FTIR and Raman spectroscopy analysis.
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.
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.
Incidence and exposure to microplastics in table salt present in the Iran market
Scientists tested 40 brands of table salt sold in Iran and found microplastics in every single sample, with sea salt containing the highest levels. The estimated daily intake from salt alone was up to 174 microplastic particles per person. This adds to growing evidence that table salt is a consistent dietary source of microplastic exposure for people worldwide.
Microplastic contamination in processed and unprocessed sea salts from a developing country and potential risk assessment
Researchers found that sea salts from Bangladesh contained 157-195 microplastic particles per kilogram, 2-3 times higher than levels reported in other countries, with unprocessed salts containing more contamination than processed varieties.
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.
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.
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.
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.
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.
Detection of Microplastic in Sun-Dried Salt using Spectroscopic Technique
Researchers used spectroscopic techniques to detect microplastics in sun-dried sea salt from South Korea. Microplastics were found in the salt samples, confirming that sea salt produced from ocean water is a pathway through which humans can ingest plastic particles through everyday food consumption.
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.
Identification and quantification of common microplastics in table salts by a multi-technique-based analytical method
Researchers developed a multi-technique analytical method combining microscope-FTIR and pyrolysis-GC/MS to identify and quantify microplastics in table salts, providing 3D information on polymer type, morphology, and chemical composition of food-grade salt contaminants.
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.
