Africa-Press – Ghana. <\/strong><\/span>A team of McGill University researchers has developed a cost-effective, high-throughput technology for detecting nanoplastics and microplastics in the environment.<\/b><\/p>\n

These particles are pervasive, posing health and environmental risks, yet detecting them at the nanoscale has been difficult.<\/p>\n

The 3D-printed HoLDI-MS (hollow-laser desorption\/ionization mass spectrometry) test platform overcomes the limitations of traditional mass spectrometry by enabling direct analysis of samples without requiring complex sample preparation.<\/p>\n

The researchers say it also will work for detection of waterborne plastic particles.<\/p>\n

Chemistry Professor Parisa Ariya, who led the study published recently and said \u201cWith HoLDI, we provide a method that is effective, quantitative, highly accurate and affordable, making it accessible to researchers worldwide,\u201d<\/p>\n

\u201cIt requires little energy, is recyclable and costs only a few dollars per sample.\u201d<\/p>\n

The new method will also advance international co-operation in fighting plastic pollution, in alignment with calls by the United Nations Environment Programme to improve methods, the researchers say.<\/p>\n

\u201cUntil now, there have been no established universal protocols for nanoplastic detection within the complex environment,\u201d Ariya said.<\/p>\n

\u201cThis technology allows us to pinpoint the major sources of nano and microplastics in the environment,\u201d she said.<\/p>\n

\u201cMore importantly, it enables data comparison and validation across laboratories worldwide, a crucial step toward harmonizing global research on plastic pollution.\u201d<\/p>\n

As part of their study, the researchers identified polyethylene and polydimethylsiloxanes in indoor air, and polycyclic aromatic hydrocarbons in outdoor air.<\/p>\n

This work was funded by Natural Sciences and Engineering Research Council of Canada (NSERC), the Canadian Foundation for Innovation (CFI) and National Research Council Canada (NRC).<\/p>\n

Affordable, efficient, HoLDI-MS will facilitate global monitoring of plastic pollution, the researchers said.<\/p>\n
