Abstract:

Experiments were performed to investigate the biotransformation of the pesticides alachlor, propachlor, atrazine, and bromacil under aerobic and nitrate-reducing conditions. Glass bead columns with attached, acetate-supported biofilms were used. Degradation of alachlor and propachlor was significant in both columns, and was not sensitive to short-term losses in the primary substrate. Biotransformation of bromacil and atrazine was minimal in these cultures, regardless of the amount of acetate present.
