Nano-plastics in bottled drinking water


Nano-plastics in bottled drinking water

Recent studies have shown that microplastic pollution has reached the food chain affecting not only marine fauna but also foods such as sea salt, beer and honey. Although specific studies have not been conducted, there is also the possibility that the fragments arrive on our tables through meat; in fact, poultry and pigs are also fed with flour made from small fish that can be contaminated.

Some studies have found that a person can ingest up to 5 grams in a week. The German Institute for Food Risk Assessment (BfR) has called on the European Food Safety Authority (EFSA) to investigate the effects of microplastics on human health.

Microplastics have been found in the human body, especially in the placenta of pregnant fetuses and in blood circulation. Additional traces of microplastic were found within the lung tissues.

Characteristics of nano-plastics in bottled drinking water, a study published in the Journal of hazardous materials, talks about the risks of this issue.

The researchers told: "Plastic pollution in water is threatening the environment and human health. Previous relevant studies mainly focus on macro and micro plastic pollutions and their characteristics. Little is known about the extent and characteristics of nano-scale plastics in our drinking water systems , mainly due to difficulties in their isolation and analysis.These nano-plastics may pose higher risk to human health than micro-plastics.

Here we report the collection and analysis of organic nanoparticles from commercial bottled water of two brands.Novel nano-plastic particle imaging and molecular structure analysis techniques have been applied.The findings show the existence of organic nanoparticles, and a likely source has been identified to be the degradation of plastic water bottles." Microplastics are also contained in the air, according to some studies on the highest peaks of Italy millions of microplastic particles fall every year and, at the end of winter, when the snow has melted, these end up in waterways.

Microplastics pose a serious threat to small marine living beings, which tend to feed on them by mistaking them for plankton.
