You are here: News Chemicals leach from food-grade plastic
Although labeled as food-safe by the Food and Drug Administration (FDA), some plastic bags can leach chemicals that are highly toxic and the toxicity can vary among products having the same label. Heather J. Hamlin and her team (University of Maine) illustrated this in a study published by the scientific journal Chemosphere.
Scientists investigated whether nonylphenol (NP, a common chemical used as a plasticizer in industry and commercial products) can leach from some plastic bags labeled as food-safe into their contents. They conducted an experiment using sea water and the tropical coral fish (pseudochromis fridmani). The fish are often used for hobby purposes and are usually transported in similar food-grade polyethylene plastic bags (PE1 and PE2). For comparison, fish were also kept in various containers including, glass bowls and Teflon bags.
After 48 hours:
- Fish kept in plastic bags contained high concentrations of NP
- Short and longterm survival of these fish decreased
- All fish kept in PE2 perished by day eight, while all fish in the control treatment survived
- There were no observed effects in fish kept within a glass bowl or a Teflon bag.
Plastic bags used in these experiments were made of food-grade plastics approved by US FDA and are considered as safe for storing and carrying food for consumption. However, the study at hand shows that although a product may have an identical label, the toxicity of products may vary considerably between manufacturers. NP-levels that are leached can vary depending on the plastic, posing a greater risk to the aquatic environment as well as to human health than previously thought.

Towards a global Plastic Treaty
By the end of this year, there should be a global plastic treaty that will stop plastic pollution of our planet. To achieve this, the United Nations environment department is organising the Intergovernmental Negotiation Committee on Plastic Pollution negotiations. The 4th round, INC4, took place in Ottawa Canada. The new plastics treaty is considered one of the most important environmental agreements made since the Paris climate accords in 2015. The stakes are high and that was evident in Ottawa.

Business has blind spot: 85% citizens are plastic tired
Eighty-five per cent of citizens want single-use plastic packaging to disappear completely. This is according to new research by Ipsos commissioned by the World Wildlife Fund (WWF) and the Plastic Free Foundation. Entrepreneurs who abandon packaging or make it more sustainable seem to have tapped into a goldmine – but part of the business community is still deaf and dumb. ‘People are getting fed up with all the plastic in the supermarket.’
