McMaster researchers identify cause of Hamilton’s mystery soot
Researchers with McMaster University have identified the cause of a mysterious black grime that has blanketed houses and yards near the city's industrial area for decades.
Researchers at McMaster University have pinpointed the cause of a perplexing black residue that has plagued homes and yards in Hamilton's industrial region for years. Dubbed the "What's The Grime" study, the team analyzed samples and revealed that coal combustion is likely responsible for the dust. The investigation further uncovered that the soot's composition is intricate, suggesting multiple sources contribute to its formation.
Grace Yao, a McMaster PhD student and co-lead of the study, emphasized that the grime poses the greatest risk to small children and pets, who might unintentionally consume it. Community members are growing increasingly frustrated, as there's a lack of clear guidance on how to protect themselves and their gardens from the soot. Yao noted that there is limited public information on safety measures and proper cleaning methods.
Her team intends to conduct a follow-up study to better understand the grime's origins and characteristics, addressing community concerns in the process.
