When it comes to plastics polluting our water, it’s not just the world’s oceans we need to worry about says U of T assistant professor Chelsea Rochman.
“The contamination in the Great Lakes and other bodies of freshwater from plastics and microplastics is ubiquitous,” says Rochman, whose lab focuses on the fate of plastic debris and its associated chemical contaminants.
She points to published research, in addition to work in her lab and with colleagues, that finds the concentrations of plastics in areas of the Great Lakes are equal to or greater than those reported in the ocean. Their work in Lake Ontario, Lake Superior and Lake Huron has also found microplastics (particles five millimetres and smaller) in nearly all fish collected.

Farmers in Argentina, Brazil, India, Indonesia, Kenya and Uruguay are increasing crop yields and enhancing the fertility and quality of the soil in an environmentally friendly, cost-effective way – thanks to the results of an IAEA coordinated research project recently concluded in collaboration with the Food and Agriculture Organization of the United Nations (FAO).

The data on saving soil and protecting water quality is clear. Conservation practices work. However, they take time and money, and other priorities can get in the way. The Root River Field to Stream Partnership gathered data, but more importantly, it engaged with growers and encouraged conversations among growers that led to positive changes.

CRP is a federal program that pays landowners to take environmentally sensitive land out of production, with the land planted to grass and other vegetation. CRP contracts are for either 10 to 15 years — and the land potentially can be re-enrolled — so the vegetation typically is in place for many years.
That complicates returning the land to crop production. The no-longer-desired vegetative cover needs to be destroyed or removed, which requires both time and money. Weeds or insects or both can pose special problems. Often, over time, the land has become rough or bumpy, increasing the difficulty of planting and harvesting it. And soil nutrients, especially nitrogen, which is crucial to plant growth, usually are low and need to be replenished.

Since 2011, Ohio has spent more than $3 billion on efforts to solve Lake Erie’s harmful algal bloom problem. Yet the majority of the money isn’t going to projects that stop algal blooms at the source.

Stormwater retention ponds, a ubiquitous feature in urban landscapes, are not a significant source of climate-warming nitrous oxide emissions, a new study finds. Nitrous oxide is a potent greenhouse gas that contributes to global warming and destroys stratospheric ozone. Previous studies suggested stormwater ponds might be a problematic source of the gas, since they produce it as a by-product of the denitrification process that removes excess nitrogen from urban runoff.

Replacing fallow lands with cover crops in order to increase the levels of carbon and soil nitrogen also enhances its quality and mitigates nitrate leaching in an agricultural land, according to a new analysis.
