$1M NSERC grant to study the health risks of nanoplastics

This research will allow Professor Cyr and research teams from INRS, Canadian and Brazilian universities, Health Canada, and Environment and Climate Change Canada to assess how these contaminants affect the body's inflammatory response.

MONTRÉAL and LAVAL — Nanoplastics — tiny plastic particles invisible to the naked eye — may exert an effect on nervous, immune, and reproductive systems of humans. To further explore this issue, Professor Daniel G. Cyr of Institut national de la recherche scientifique (INRS) has received funding through the Natural Sciences and Engineering Research Council of Canada’s (NSERC) and Environment and Climate Change Canada’s (ECCC) Plastics science for a cleaner future funding opportunity. The study will be among the first to address this issue.

The health impacts of products used to make plastic, such as phthalates, bisphenol, and polystyrene, have previously been studied. However, few toxicological studies have assessed the risk of exposure to nanoplastics. These tiny pieces of plastic can be found everywhere in the environment, including in food and drinking water.

The effects of inflammation

This research will allow Professor Cyr and research teams from INRS, Canadian and Brazilian universities, Health Canada, and Environment and Climate Change Canada to assess how these contaminants affect the body’s inflammatory response. “Increased inflammation is linked to several neurodegenerative diseases, imbalanced immune responses, and altered fertility,” said Professor Cyr. “Unlike chemicals emanating from plastics which are rapidly metabolized, plastic fragments could have long-term consequences.”

An international study

Over the next four years, Daniel Cyr will collaborate with scientists from Canada and Brazil. At INRS, professors Krista Heinonen, Simona Stäger, Albert Descoteaux, Alain Lamarre, and Stéphane Lefrançois are involved in the research.

Scientists from McMaster University, the University of Ottawa, Health Canada, and Environment and Climate Change Canada will also contribute their expertise. Brazilian reproductive toxicology experts from Universidade Estadual Paulista (UNESP) in São Paulo State and Universidade Federal Rural do Semi-Árido in Mossoró will study transgenerational effects of plastics.

The group is currently recruiting undergraduate and graduate students to work in Canada and Brazil starting this summer.
