Chromatographic analyses of chlorpyrifos degradation, microorganism
counts (bacteria, fungi, and actinomycetes), and total
microbial activity in the soils were performed in triplicate. All data
are presented as means ± st. dev. The statistical significance of the
data were evaluated by one-way analysis of variance (ANOVA). A pvalue
of less than 0.05 was considered statistically significant unless
otherwise indicated. If an overall significance was detected,
Tukey's multiple range tests were performed
