Interpreting results from biodegradability tests of chemicals in water and soil

Biodegradability testing is examined and the many factors affecting extrapolation of laboratory biodegradation results to microbial degradation in the environment are discussed. Recent advances in the understanding of the effects of the concentration and nature of various nutrients and organic substrates and modeling the microbial kinetics of degradation are reviewed. The advantages and disadvantages of screening methods and grab sample testing are discussed. The importance of groundwater biodegradation is also examined. Research needs are identified and guidelines are given to select various testing procedures to model diverse environmental situations.
