Microplastic Contamination in Common Salt from Seawater
Summary
This book chapter examines microplastic contamination of sea salt produced from evaporation of seawater, reviewing evidence that salt from multiple countries contains MPs and discussing the human dietary exposure implications of consuming salt with plastic particle contaminants.
The consumption of common salt, derived from seawater, faces a pressing concern – microplastic (MP) contamination. Microplastics, defined as particles smaller than 5 mm, pervade marine environments, with prevalent types including polyethylene, polypropylene, polystyrene, polyamide, polyester, and polyacrylates. This overview addresses global MP contamination in seawater-derived salt, emphasizing surveys estimating MP presence in both edible and industrial salt. Factors affecting contamination, such as geographical location, ocean currents, and human activities, are explored. The chapter also emphasizes potential health hazards associated with ingesting MPs through salt consumption, raising concerns among consumers and producers. Proposed measures aim to reduce human exposure, focusing on separation techniques during salt production. Current limitations in estimation methods and future research prospects are outlined. This information is crucial for academics and salt producers, contributing to safer salt production and consumption practices amid rising awareness of MP contamination.
