A laboratory procedure was developed to measure the microbial toxicity in soils using respirometric technique. The procedure was tested on 35 organic chemicals and several 8- and 10- component equitoxic mixtures. The chemicals assayed in this study were found to act jointly by simple addition. A modeling approach incorporating partitioning, sorption and Quantitative Structure Activity Relationship (QSAR) techniques was developed to estimate single chemical and mixture toxicity. This modeling approach was validated using an external testing set of data.
