Microplastic pollution threat in table salt that an abiotic sea product
AI summary Read the abstract
This Turkish study investigates microplastic contamination in commercially sold table salt, finding plastic particles in sea salt products. Table salt is consumed daily, and microplastic contamination in this product represents a potential route for regular human dietary exposure.
Plastiklerin tabiatta parçalara ayrılması dolayısıyla da mikroplastiklerin (<5mm) oluşması doğal olarak hava, rüzgar, güneş ve su akışı etkileriyle ve/veya antropojenik etkilerle gerçekleşebilir. Mikroplastik kirliliği günümüzde yeni anlaşılan bir konudur. Son zamanlarda çevrede ve sulardaki mikroplastik kirliliği konusunda yapılmış çalışmalar artsa da gıdalardaki mikroplastik kirliliği ve sağlığa etkileri açısından yapılmış pek fazla çalışma bulunmamaktadır. Yemek tuzu, basit üretim teknikleri ile deniz, göl ve kaya (kuyu) gibi doğal kaynaklardan temin edilmektedir. Abiyotik bir su ürünü olan tuz, günlük hayatta çok kullanılan ve “üç beyaz” olarak bilinen gıda maddelerinden biridir. Yapılan bu çalışmada ülkemizdeki marketlerden alınan ve temel gıda maddelerinden biri olan sofra (yemek) tuzlarındaki mikroplastik kirliliği incelenmiştir. İncelemeler sonucunda yemeklik tuz içerisinde bulununan mikroplastik sayısının hiçte azımsanamayacak miktarda olduğu anlaşılmıştır. Kaya tuzlarında ortalama 28, deniz tuzlarında 56 ve göl tuzlarında 63 MP/200g tespit edilmiştir.

Contamination of table salts from Turkey with microplastics
AI summary Read the abstract
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 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.
Contamination of table salts from Turkey with microplastics Part A Chemistry, analysis, control, exposure & risk assessment
AI summary Read the abstract
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.
Risk assessment of microplastic in commercial salt sold in Malaysia
AI summary Read the abstract
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 pollution in commercial salt for human consumption: A review
AI summary Read the abstract
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.
