Final report to Texas Water Quality Board, Galveston Bay Study Program.2010-02-152010-02-151973http://hdl.handle.net/1969.3/19061p. VII-1 - VII-24No significant effect was noted that might be caused by a toxicity factor because of the non-correlation of the five day BOD, dilution or reaeration and larger container size. The high oxygen uptake in reaerated samples in non-dilution tests were used to relate to the toxicity in previous studies where dilution was used. The variability of BOD data as correlated with data on nutrients, turbidity, oxygen, etc. carried out during the one year study indicate that the BOD may not be a reliable test for organic matter content including toxicants in the Galveston Bay environment. The data will be kept on file for future references and research in Galveston Bay.toxicityaerationorganic matterbiochemical oxygen demand (BOD)Chapter
