MICROBIAL DEGRADATION OF PARAQUAT RESIDUE IN SOIL

ISMAIL SAHID, SUKIMAN SARMANI AND ABDUL FATAH AMIR

SUMMARY

The degradation of paraquat in two types of soil, Serdang and Renggam Series was discussed. The results showed that paraquat molecules were strongly adsorbed onto Renggam Series soil. However, the degradation process was more rapid in Serdang than Renggam Series Soil, as determined by analysis of ¹⁴CO₂, evolved during incubation. Higher ¹⁴C residues were detected in Renggam Series which confirmed it to have a slower degradation Drocess.
