Gıdamızda plastik mi?

Bu çalışma gerçekten göz açıcı!

Plastic pollution has been well documented in natural environments, including the open
waters and sediments within lakes and rivers, the open ocean and even the air, but less
attention has been paid to synthetic polymers in human consumables. Since multiple toxicity
studies indicate risks to human health when plastic particles are ingested, more needs to be
known about the presence and abundance of anthropogenic particles in human foods and
beverages. This study investigates the presence of anthropogenic particles in 159 samples
of globally sourced tap water, 12 brands of Laurentian Great Lakes beer, and 12 brands of
commercial sea salt. Of the tap water samples analyzed, 81% were found to contain anthropogenic
particles. The majority of these particles were fibers (98.3%) between 0.1±5 mm in
length. The range was 0 to 61 particles/L, with an overall mean of 5.45 particles/L. Anthropogenic
debris was found in each brand of beer and salt. Of the extracted particles, over 99%
were fibers. After adjusting for particles found in lab blanks for both salt and beer, the average
Bira içinde bulunan parçacık sayısı 4.05 parçacık/L olarak bulunmuş olup, 0 ile 14.3 parçacık arasında değişmektedir.
Tuzun her markasında bulunan ortalama parçacık sayısı ise 212 parçacık/kg olup, 46.7 ile 806 parçacık arasında değişmektedir. Tüketici kılavuzlarına dayanarak, sonuçlarımız ortalama bir kişinin bu üç kaynaktan yıllık 5,800'den fazla sentetik kalıntı parçacığı tükettiğini göstermektedir.
En büyük katkı musluk suyundan gelmektedir (%88).
