ClearAn 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.
Microplastics pollution in salt pans from the Maheshkhali Channel, Bangladesh
Researchers analyzed sea salt samples from eight salt pans in the Maheshkhali Channel of Bangladesh and found microplastic contamination in every sample, with concentrations ranging from 78 to 137 particles per kilogram. Fragments were the most common type, and the dominant polymers identified were terephthalate, polypropylene, polyethylene, and polystyrene. The findings highlight that sea salt represents a potentially significant route of human dietary exposure to microplastics.
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 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.
Proliferation of microplastics in commercial sea salts from the world longest sea beach of Bangladesh
Researchers analyzed 13 commercial sea salt brands from Bangladesh and found an average of 2,676 microplastic particles per kilogram — among the highest levels reported globally — with polystyrene and polyethylene fragments and fibers being the most common types. Based on typical salt consumption, Bangladeshis may ingest over 13,000 microplastic particles per year through salt alone, raising public health concerns.
Microplastic presence in commercial marine sea salts: A baseline study along Tuticorin Coastal salt pan stations, Gulf of Mannar, South India
Twenty-five sea salt samples from Tuticorin coastal salt pans in India were analyzed for microplastics, with particles under 100 μm comprising 60% of contaminants and polypropylene and polyethylene as the dominant polymers. The study establishes a baseline for microplastic contamination in commercially harvested sea salt from South India.
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.
Assessment of microplastics in coastal ecosystem of Bangladesh
Researchers surveyed microplastic contamination in water, beach sand, and fish along two major coastal areas of Bangladesh. Microplastics were found in every sample type, with fibers being the most common shape and polyethylene and polypropylene the dominant plastic types. Fish accumulated microplastics in their digestive tracts and body tissues, raising concerns about human exposure through seafood consumption in the region.
An Integrated Spatial Assessment of Macro-, Meso-, and Microplastic Pollution Along Cox’s Bazar Beach in Bangladesh
Researchers conducted the first comprehensive assessment of macro-, meso-, and microplastic pollution along the full coastline of Cox's Bazar in Bangladesh, sampling 23 stations across tourism, active, and less active beach zones. Plastic abundance varied significantly by zone and land use, with fragments and films as dominant types, reflecting Bangladesh's high plastic waste mismanagement rates.
Microplastic pollution in coastal Cox's Bazar, Bangladesh: Quantification, distribution, and characteristics
This study surveyed microplastic pollution along the Cox's Bazar coastline in Bangladesh, one of the world's longest beaches, finding significant contamination in both sediments and seawater with levels varying by tidal zone and beach location. Polyethylene was the most common polymer type, and scanning electron microscopy revealed weathered particle surfaces indicating long-term environmental exposure. The findings establish a baseline for microplastic monitoring in a heavily visited coastal region with limited waste management infrastructure.
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.
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.
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.
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.
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 salt pans and commercial salts – A baseline study on the salt pans of Marakkanam and Parangipettai, Tamil Nadu, India
Microplastic contamination was documented in commercial table salts and salt pan waters from two sites in Tamil Nadu, India, with fiber types dominating samples and concentrations reflecting regional coastal and atmospheric plastic pollution inputs.
