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.
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 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 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.
Health risk and ecological risk assessment from microplastic contamination in sea salt : case study in Ban Laem salt field, Phetchaburi, Thailand
Researchers assessed microplastic contamination in Thai sea salt and found hundreds of particles per kilogram across both traditional and plastic salt fields, with polyamide, polyethylene, and polypropylene fragments most common, posing measurable ecological and potential human health risks.
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 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.
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 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 pollution from sea salt: its effect on public health and prevention alternatives - a review
This review examines microplastic contamination in sea salt from countries that export to Indonesia, summarizing polymer types, contamination levels, public health effects of ingested microplastics, and potential prevention strategies to reduce human salt-borne plastic exposure.
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.
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.
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.
Emerging Microplastic Contamination in the Food Industry: the Case of Commercial Table Salts in Iligan, Philippines
Commercial table salts from markets in Iligan City, Philippines were analyzed for microplastic contamination, contributing to limited data from the country on this food safety issue.
