We have around one month left in Antarctica and we’re making the most of it!
Our DGT have been deployed to sediments in meltstreams:
To spots in the ocean:
To freshwater lakes:
Soon to marine sediments (we’ve got them sitting in big tubs of seawater to acclimate):
And soon to soils:
DGT work by accumulating metal contaminants through a diffusive membrane. This acts kinda like the skin of a worm, the gills of a fish, or the membrane of a microalgae. That way, we can see what contaminants are actually able to cause toxicity to organisms. We’re hoping to couple what DGT measure with our knowledge of environmental toxicology to assess the overall risk of contaminants in the environment. This will help decision makers and environmental managers better target remediation efforts and current environmental practices!
