  abstract = {{E}arthworms are known to increase availability of heavy metals in soils and also play an important role in {M}aintaining the structure and quality of soil. {T}he introduction of earthworms into soils contaminated with metals in the presence of a potential hyperaccumulator has been suggested as an aid for phytoremediation processes. {T}he present study was conducted to evaluate: (i) the effects of earthworms on lead availability in artificially contaminated soil at 500 and 1000 mg kg(-1) {P}b in the presence of {L}antana camara, a hyperaccumulator, (ii) the effects of earthworms and lead on soil properties such as p{H}, cation exchange capacity ({CEC}), organic matter ({OM}), total and available {N}, {P} and {K} and (iii) soil enzyme activities. {E}arthworms increased the bioavailable {P}b in root-adhering soil by a factor of 2 to 3 in the contaminated soils at concentrations of 500 to 1000 mg {P}b kg(-1), respectively. {I}n lead contaminated soils, the presence of earthworms led to a significant decrease in soil p{H} by about 0.2 but increased {CEC} by 17% and {OM} by more than 30%. {E}arthworm activities also increased the activities of {N}-acetylglucosamidase, beta-glucosidase, cellulase, xylanase, alkaline and add phosphatase, urease and fluorescein diacetate assay ({FDA}). {T}hese results indicate that the ecological context for phytoremediation should be broadened by considering plant-soil-earthworm interactions as they influence both plant health and absorption of heavy metals. {T}hey also showed that the enzyme activities monitored could serve as useful proxies for phytoremediation capability and, more generally, for soil quality as a whole.},
