The distribution of bacterivorous nematode genera along a distance gradient from a 50 years old Thermal power station was studied. Sampling distances were 500m (A), 1000m (B), 2000m (C) and 4000m (D) from the station. Soil chemical properties were analyzed and the abundance of nematode genera were studied in relation to pH, available carbon, available potash and available phosphates in the soil. The concentration of available carbon increased and consequently decreased with distance Eucephalobus was overall dominant genus at the four sites. The abundance of Acrobeles and Eucephalobus (P< 0.05) was significantly correlated with distance from source, while abundance of Acrobeles, Eucephalobus (P < 0.05) and Plectus (P < 0.01) significantly correlated with available carbon. Acrobeles, Acrobeloides, Rhabditis and Panagrolaimus were correlated with pH, available carbon and available phosphates while no nematode genus correlated with available potash.
