Northern Region Persistent Organic Pollution Control (NRPOP) Laboratory

Research Facility



Northern Region Persistent Organic Pollution Control (NRPOP) Laboratory
Memorial University
St. John's
Newfoundland and Labrador (NL)

With a strong commitment to northern regions, the Northern Region Persistent Organic Pollution Control (NRPOP) Laboratory aims to conduct integrated modelling and experimental research on the development of innovative investigation, simulation, control and remediation technologies that are applicable to mitigate the contamination caused by persistent organic pollutants (POPs). The research in the NRPOP lab will not only enhance researchers’ understanding of the pollution mechanisms but also help governments and industries improve their practices for mitigation of the POPs-related pollution problems, leading to short-/long-term environmental, economic and social benefits.
