Microplastics are found in drinking water and even in table salt
AI summary Read the abstract
Microplastics have been detected in both tap water and table salt, indicating that everyday food and drink is a direct pathway for human dietary exposure to plastic particles.

Microparticles in Table Salt: Levels and Chemical Composition of the Smallest Dimensional Fraction
AI summary Read the abstract
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.
The presence of microplastics in commercial salts from different countries
AI summary Read the abstract
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 and Characterization of Microplastics in Commercial Salts in India
AI summary Read the abstract
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
AI summary Read the abstract
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 of salt intended for human consumption: a systematic review and meta-analysis
AI summary Read the abstract
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.
