Measuring the impact of septic systems on streams

Environmental chemist Michael Gonsior has been dipping into streams in southern Maryland to figure out if septic systems in residential areas are contributing to nitrogen pollution in local waterways--and ultimately the Chesapeake Bay. He's been using a surprising clue to track down the pollution: sucralose, an artificial sweetener used in many food products.

" Knowing what the sources of nitrogen are in streams is important to mitigate and to find solutions to potentially reduce them or at least find ways to reduce nutrient loading in waterways in the most cost-effective way," he said.

Women pursuing graduate degrees in science today are part of a tide of change. Check out a series of podcast interviews with female graduate students at UMCES' Laboratories about what inspired them to pursue careers science, the power of diversity, their plans for the future, and advice for the next generation to come. 

Fish raised in aquaculture are mostly fed a protein diet that includes other fish farmed from the ocean. Al Place talks about the steps it took to create a simple plant-based diet that could turn farmed fish into vegetarians and curb overfishing of the world's oceans at the same time.

"I work on the link between diet and inflammation and ways to mitigate that in fish. It's really important especially now as the aquaculture industry tries to move toward more sustainability. Instead of taking fish from the ocean and feeding them to farmed fish, we're looking at introducing them to plant protein sources to replace the fish meal. Some ingredients are not working well for some kinds of fish and may actually induce inflammation, so we're trying to figure out what ingredients may cause problems for which fish and see how we might be able to mitigate those negative effects."
