The objective of this study was to verify whether a commercial formulation of 2,4 dichlorophenoxyacetic acid [2,4-D dimethylamine salt (DMA)] affects the growth and biochemical parameters of silver catfish (Rhamdia quelen) after 90 days of exposure. The fish exposed to 0.5 or 2.0 mg/L of DMA presented exhibited decreased growth parameters. Glucose was reduced in the mucus layer at both concentrations, and the total protein level was increased at the highest concentration tested. Fish exposed to DMA showed reduced liver and kidney glycogen at both concentrations tested, while in the muscle, glycogen was reduced only at 2.0 mg/L. Glucose was increased in the liver and decreased in the muscle and kidney at both concentrations and was not altered in the plasma. Lactate was increased in all the tissues and decreased in the plasma. Protein levels were reduced in the liver and plasma at both concentrations, while in the muscle, it was decreased at a concentration of 2.0 mg/L. Levels of thiobarbituric acid-reactive substances were reduced in the liver and increased in the muscle at both concentrations and did not change in the brain. DMA increased catalase activity in the liver at both concentrations tested. The present study demonstrates the effects of long-term exposure to DMA. Some parameters could be used as toxicity indicators to identify the presence of DMA in an aquatic environment.

“…The immunotoxicity and the ecotoxicological damage on diverse aquatic species caused by atrazine, as a pure compound or mixed with other agricultural chemicals, is largely documented (Russo and Lagidick 2004;Sullivan and Spence 2003;Fatima et al 2007). It is a clastogenic compound, a possible carcinogen (Cantemir et al 1997) and a known endocrine disruptor for amphibians of the aquatic biota (Fatima et al 2007).…”

Through selective enrichment of atrazinemetabolizing microorganisms, a microbial community was selected from agricultural soil. Bacterial isolates, identified by their closest similarity with 16S rDNA sequences stored in NCBI GeneBank, belonged to the genera: Massilia, Stenotrophomonas, Klebsiella, Sphingomonas, Ochrobactrum, Arthrobacter, Microbacterium, Xanthomonas and Ornithinimicrobium. From these strains, only the first six used atrazine as nitrogen and carbon source. The microbial community attached to a non-porous support was evaluated for its atrazine biodegradation rate and removal efficiency under aerobic conditions in two types of packed-bed biofilm reactors fed with a mineral salt medium containing glucose plus atrazine, or atrazine as the sole carbon and nitrogen source. Removal efficiencies near 100% were obtained at loading rates up to 10 mg l -1 h -1 . After long periods of continuous operation, the richness of microbial species in biofilm reactors diminished to only three bacterial strains; Stenotrophomonas sp., Ochrobactrum sp. and Arthrobacter sp. By PCR analysis of their DNA, the presence of atzABC genes codifying for the enzymes of the upper catabolic pathway of atrazine, was confirmed in the three strains. The gene atzD that encodes for the cyanuric acid amidohydrolase enzyme was detected only in Stenotrophomonas sp.
