For the past two summers, the 21 year-old Micmac from Blanc Sablon, Quebec has been diligently studying ocean algae. Then, we add or take away trace metals to see how it affects the algae's growth. Looking at trace metals in plant life is important because high levels can be toxic.
Careful measurement plays a vital role in the study.
We start with 20 litres of sea water that was created using a recipe which mimics natural ocean water. By observing the growth rate of the algae, we'd be able to tell the effects of varying degrees of cadmium. In the bigger picture, cadmium can leak into water from pipes and solder or may enter water from chemical waste disposal sites. Contamination in the food chain affects the quality and safety of the foods we eat.
