Although aquaculture in treated wastewater is practiced worldwide, there is scant scientific research concerning whether organic micropollutants are present at safe levels for consumption.

A new study in Aquaculture by researchers at Ben-Gurion University of the Negev has determined that organic micropollutants in the water—trace elements of heavy metals, pharmaceuticals and personal care products as well as pesticides, solvents, and detergents—result in minimal accumulation in fish. Additionally, the wastewater does not appear to affect other commercially important traits of fish.
