Plastic rocks on an isolated island
The sombre message of stones made of plastic found on an uninhabited island far from the Brazilian coast.
In a recent study, evidence shows that the Vibrio spp. genus of bacteria can populate floating pieces of microplastics in the marine environment. Vibrio spp. is a well-known genus of bacteria containing pathogenic strains to humans (e.g. cholera) and animals alike. Plastic debris and microplastics have a low biodegradability making them persist in the environment and potential vectors for spreading pathogens. A group of researchers in Germany recently published their study in the journal Marine Environmental Research. The researchers collected samples from 39 stations in the North Sea and 5 in the Baltic Sea and their paper illustrates that:
This study further reinforces the issue of plastic pollution and its effect on the quality of water and the marine environment. The fact that pathogenic strains of the Vibrio genus of bacteria are able to survive on microplastics is disconcerting. The study at hand focused only on Vibrio spp., but perhaps it is only the tip of the iceberg when it comes to human pathogenic bacteria on floating plastics.

Cosmetics companies selling personal care products without microplastics are calling for the swift introduction of a total ban in an open letter.
In Bali, more and more rivers are being cleaned from plastic waste every day. What do Dutch travel suitcases made from recycled ocean plastic have to do with that?
Scientists suspect that fat formation in human bodies is stimulated by plastic.
