Kahnawake reports high lead levels in air near high school

The Mohawk Council of Kahnawake has released preliminary test results indicating high levels of lead in the air near the Kahnawake Survival School. When wind direction was blowing west toward the community, lead levels averaged 1.5 times higher than the provincial standard of 100 nanograms per cubic metre.

These elevated levels occurred near the community's eastern boundary, close to an industrial area containing waste management plants. The school is located less than one kilometre from this industrial zone. While levels were well below the threshold when the wind blew east—which occurred 80 per cent of the time—the council is collaborating with Environment Canada for further analysis.

Mylène Ratelle, a professor at the Université de Montréal’s public health school, described the findings as a “yellow flag” that warrants investigation rather than panic. She noted that lead levels during west winds were approximately 100 times higher than averages in non-industrial areas. Ratelle emphasized the potential risks to children, noting that younger populations are more vulnerable to the neurotoxic and cognitive effects of lead exposure.
