In a study with workers from a Sepiolite Nanoclay production plant, it was found that lung function deteriorated more rapidly in those who had received more exposure to dust. In Asia and the US nanoclays are allowed in food packaging. Particles of packaging can migrate in small amounts in food.


Worker in the warehouse ©industrieblick/fotolia.comIn one of the largest Sepiolite production plants in the world, very high concentrations of this nanoclay dust were recorded in the bagging department [1]. A study of the 218 workers has shown that extensive exposure results in a lowering of lung function. Nanoclays are able to migrate from food packaging (approved in Asia and the US, banned in the EU) into food. The amounts are very low [2].
