Dioxin risk in soil and plant tissues after long-term biosolids application
Date:7/14/2008

MADISON, WI, JULY 14, 2008 Land application of biosolids (treated municipal sewage sludge) is a common practice because biosolids are a rich source of plant nutrients and organic matter. However, the presence of detectable levels of dioxins in biosolids led to concerns that farmland application may result in accumulation of dioxins in soil and their subsequent translocation through the human food chain because several congeners of dioxins have extremely high bioaccumulation potential. The USEPA evaluated the risk of dioxins in land applied biosolids and concluded that dioxins from this source do not pose a significant risk to human health or the environment. However, there is very little information available on the effect of long-term application of biosolids on accumulation of dioxins in soil and uptake by plants.

Scientists at the Metropolitan Water Reclamation District of Greater Chicago (District) investigated the effects of continuous and long-term application of biosolids on the levels of dioxins in soil and corn tissues collected from the District's long-term field plots that were established in 1973. Specifically, they collected soil, corn grain, and corn stover samples from the field plots consisting of a 0 (control), 504, and 2016 Mg ha-1 cumulative biosolids loading applied through annual applications from 1973 to 2002 and measured 29 congeners of dioxins, furans, and polychlorinated biphenyls (PCBs). Results from this study were published in July-August 2008 issue of the Journal of Environmental Quality. This research was also presented at the Sustainable Land Application Conference held in January 2004 in Orlando, Fla.

The study revealed that the levels of dioxins in soil from the control and agronomic rate biosolids plots were not statistically different but the soil levels of dioxins were much higher in the plots that have been receiving four times higher rates of biosolids application. Dioxins were not detected in the
