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.

Microplastics in European sea salts – An example of exposure through consumer choice and of interstudy methodological discrepancies

Researchers analyzed 13 European sea salts and found microplastics in all of them, with industrially harvested salts containing more particles than traditionally harvested ones. They estimated that a person absorbs about 14 micrograms of microplastics annually from all salt consumption, with a quarter attributable to choosing sea salt specifically. The study also found that differences in research methods across studies make it difficult to compare microplastic levels in salt worldwide.

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.

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.

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 pollution in commercial salt for human consumption: A review

This review examines microplastic contamination in commercial table salt from 128 brands across 38 countries on five continents. Researchers found that while microplastic concentrations in salt are lower than in some other food products like mussels, salt represents a significant long-term daily exposure route for the general population. The study highlights that commercial salt contaminated with microplastics may contribute to cumulative human exposure alongside other dietary and environmental sources.

Correction to “Microplastic Human Dietary Uptake from 1990 to 2018 Grew across 109 Major Developing and Industrialized Countries but Can Be Halved by Plastic Debris Removal”

Researchers published a correction to a large modeling study that tracked human dietary microplastic intake across 109 countries from 1990 to 2018, updating the units used for key intake parameters so that results are correctly expressed in kilograms per person per day. The underlying finding — that microplastic ingestion grew over this period but could be significantly reduced by removing plastic debris — remains unchanged.
