Bioassays provide inexpensive and easy-to-handle methods for the determination of phytoxic compounds, mainly herbicides, in soil and water. Their advantages are their potential for detecting only phytotoxic isomers, quantifying residues, and determining possible recropping risks within the same bioassay procedure. Their main disadvantage is that mixtures of phytotoxic compounds cannot be separated and that samples with an unknown history usually cannot be analyzed properly. Nevertheless, bioassays may be used for the quantitative determination of residues and give results comparable to physical and chemical methods.
