Measuring the environmental impression of a hydroelectric dam in Inukjuak

To measure the potential impression of those pollution, Professor Marc Amyot and his analysis crew from the Division of Organic Sciences on the College of Montreal traveled to Inukjuak. They start by characterizing the setting in its current state, earlier than the flood. This research is a part of a four-pronged analysis challenge that features monitoring the Saint-Maurice and Romaine rivers.

“The Inukjuak element of the challenge will monitor the setting to find out if there may be any deterioration of the permafrost all through the seasons, after the soil upstream of the plant is submerged,” explains Amyot. in November. “Mercury permafrost could be launched throughout cycles of freezing and thawing, after which carried downstream of the river.”

Due to this fact, measurements had been taken this summer season in order that the info could be in contrast with the info recorded after the Inukjuak hydroelectric energy station began operation.

Give attention to mercury

The crew can pay specific consideration to mercury methylation by river microorganisms.

Mercury methylation is a pure organic course of that produces methylmercury, a extremely poisonous compound that accumulates in residing tissues and will increase in focus transferring up the meals chain, from aquatic bugs to fish to organisms fish eaters, together with people.

“One of many objectives of our analysis – each in Inukjuak and on the Saint-Maurice and Romaine rivers – was to evaluate the human means to soak up contaminants and vitamins as meals is digested, ‘ added Amyot. “We’ve created a protocol that simulates human digestion within the lab so we are able to estimate what fraction of the compounds can be found, relying on how the meals is ready and cooked.”
