摘要：
Urease activity affected by toluene studing results showed as follows: Toluene had little action on Jackbean urease activity, but can remarkably increase soil urease activity in lower toluene concentrations and shorter time, the increasing variation Was 1.48 [similar to] 3.96 times than without toluene treatment in seven soil samples tested. The variation was less than 3.98% when sterilized soil samples adsorbed the Jackbean urease. It may be because toluene can kill soil microorganism, release urease within cell and subsequently urease fixed into soil organic-inorganic colloidal. Different soil pH and microbiology can lead to vary differently for urease activity.
