Arsenic – Public Health Notice on Air Emissions in Montréal-East

Arsenic

Montréal’s regional public health department (DRSP) is recommending that people not change their daily activities

As outlined in its application for a permit from the City of Montréal, the CCR copper refinery located in Montréal-East mandated the firm Hatch to conduct a study of contaminant dispersion linked to its industrial activities. The study assessed the impacts of implementing mitigation measures, including installation in 2018 of a dust collector to control refinery emissions.

The Ministère du Développement durable, de l’Environnement et de la Lutte contre les changements climatiques (MDDELCC) has asked the Montréal regional public health department at CIUSSS du Centre-Sud-de-l'Île-de-Montréal (DRSP-MTL) to assess if air emissions produced by the CCR refinery present a health risk for people living near the plant.

The regional public health department (DRSP) has issued a notice about air emissions produced by the CCR copper refinery located in Montréal-East in which it was noted that arsenic concentrations exceed ambient air standards in surrounding areas. Recommendations have since been made to CCR.

Although the exceedances observed represent a very low risk for residents living near the refinery, the DRSP recommends that concentrations be kept below the standard set by the MDDELCC.

The population should not worry about those concentrations which are very low, every though they are higher than the standards set by the MDDELCC. The levels are too low to affect the health of people living near the refinery.

However, the DRSP considers that concrete actions must be put in place. The DRSP issues recommendations to ensure the population is not chronically exposed to concentrations higher than the standard, and that concentrations do not increase over time.
