Variety of plastics and polymers microfibers can get through wastewater treatment plants and then move to the sludge, according to alert the Final Project (TFG) of a student at the Polytechnic University of Cartagena (UPCT).
Some of these micro-plastics contain potentially toxic substances such as flame retardants, detailing the samples analyzed by student Sonia Olmos Espinar.
The TFG with this student has completed the degree in Civil Engineering notes resistance microplastics and microfibers, considered emerging pollutants by its growing presence in the processes of water treatment and "the risk that they can enter the string trophic "explains Javier Bayo, director of work.
"Because runoff, these micro-plastics could end up in the sea, where it is studied that can be ingested by microorganisms and molluscs" he warns.
The micro-plastics have found various sources.
Some of them are small pieces of not properly disposed macroplásticos, while others come from products that directly use, such as cosmetics, as discussed a Final Master Thesis UPCT who also directed Bayo.
"In the environment everything is interconnected and the best waste is not produced.
We must reduce our consumption of plastic, "advises Professor.
"Some US states, including California, have already banned the use of micro-plastics in cosmetics," says his Olmos party, who is now studying at the Polytechnic's Master of Civil Engineering, Channels and Ports and has been a fellow in the Department of Hidrogea, company that helped facilitate the TFG samples analyzed through the instrumental and technical Support Service for Technological Research (SAIT) UPCT.
The brilliant student, which was for research with a grant from the Ministry to work with the Department of Chemical Engineering and Environmental UPCT now expected to continue investigating this issue.
