BURLINGTON, ONTARIO - A Canadian study of high-use drugs released from
eight municipal wastewater treatment plants suggests that effects on
invertebrates, bacteria, and plants in natural aquatic environments are
unlikely, according to a study in the journal Environmental Toxicology
and Chemistry <http://www.allenpress.com/pdf/entc_25_807_2163_2176.pdf>
.

According to the report, across Atlantic Canada, the study's researchers
found 10 acidic and two neutral pharmaceuticals in the effluents of
eight sewage treatment plants. 

In the large bodies of receiving water, drugs generally were not
detected at high concentrations; alternatively, in the small receiving
streams, drug residues continued downstream for 11 miles, the study
said.

Based on the results of laboratory toxicity tests, the researchers
concluded that the concentrations measured were not causing harm, the
analysis concluded.
