Objectives: The objective was to examine the nature, the extent and the variation of the impact of edaphic factors and heavy metals (Pb, Zn, Cu) on soil acarine populations at different disturbed habitats and at a forest site in and around a metropolitan township. Method: Four differently used edaphic habitats __ampersandsignndash; a solid waste disposal site, a roadside area, sides of a sewage canal and a natural forest in and around Kolkata were selected for the study. Sampling was conducted for three years with 30 days interval. Results: Soil moisture and organic carbon exhibited statistically significant and positive correlation with the mite population in all the sites (p__ampersandsignlt;0.05), while soil temperature and heavy metals showed weak or strong negative effect in most instances. Solid waste disposal site appeared worst affected. Conclusion: Edaphic factors and accumulation of heavy metals appeared to render more or less similar impact on acarine populations at the disturbed site irrespective of the nature of the habitats; at the forest site, the nature and the extent however differed.
