Constructed wetlands may help reduce hormones in wastewater
According to a report by a team of Agricultural Research Service-led members,
constructed wetlands may help reduce hormones in wastewater from hog
Constructed wetlands are been incorporated into wastewater treatments with
the aim of reducing nitrogen and phosphorus in the effluent, which can be spread
onto crop fields without causing environmental harm. However, insufficient
research has investigated the system's potential to diminish hormones that pigs
excrete into wastewater.
The work combines concerns over the effect that hormones from livestock waste
and other sources have on the environment, in particular, the negative effect it
may have on the endocrine-system function of fish and other aquatic life.
