ClearMicroplastic 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.
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.
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.
“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.
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 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.
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 Table Salt: A Study of Consumer Behavior in Cox's Bazar, Bangladesh
Researchers investigated microplastic contamination in table salt from Bangladesh and found that locally refined salt contained an average of 12 to 23 particles per kilogram, while commercial brands showed no detectable contamination due to more thorough refining processes. The study also explored consumer behavior and found that 71% of local salt users believed it was healthier than branded salt, despite the contamination risk. The findings highlight the need for better quality control and consumer education around microplastic exposure through everyday food products.
The Existence, Characteristics, Sources, and Impact of Microplastics in Salt Products in Indonesia
This systematic literature review described the presence, characteristics, sources, and health impacts of microplastics in Indonesian salt products, finding consistent contamination across regions with PP, PE, and PA as dominant polymer types. The main contamination sources were polluted seawater used in salt production and unmanaged plastic waste near coastal evaporation ponds.
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.
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.
Effect of plastic waste pollution in seawater to microplastic contamination in salt fields at Rembang
This study found microplastic particles in sea salt harvested from salt pans in Rembang, Indonesia, tracing their origin to plastic waste in the surrounding seawater. The findings add to growing evidence that microplastics contaminate table salt, representing a direct route of human dietary exposure to plastic particles.
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.
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.
Identification of Microdebris in Traditional Salts Processes from Sea Water in Woha-West Nusa Tenggara and Takalar Lama-South Sulawesi
This Indonesian study identified microdebris including microplastics in traditionally produced salt from two regions, finding contamination at multiple stages of the salt-making process. Microplastic contamination in table salt represents a direct route of human ingestion for people who consume salt produced from polluted coastal seawater.
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.
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.
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.
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.
