AQUATOX Training Workshops

A one-day short course on AQUATOX was presented as part of the Society of Environmental Toxicology and Chemistry (SETAC) North America 31st Annual Meeting, held November 7-11, 2010 in Portland, OR.

What does AQUATOX do?

AQUATOX simulates the transfer of biomass, energy and chemicals from one compartment of the ecosystem to another.

AQUATOX is an ecosystem simulation model that predicts the fate of various pollutants, such as excess nutrients and organic chemicals, and their effects on aquatic ecosystems, including fish, invertebrates, and aquatic plants.
