The chemical characteristics of an aquatic ecosystem play key role in defining its trophic status. Bhoj wetland in Bhopal is under trophic evolution as it receives large quantities of agricultural and human wastes from its catchment, resulting in significant change in its environment. The main chemical parameters which are being considered for determination of tropic status of Bhoj wetland are pH, electrical conductivity, total alkalinity, phosphorus and nitrate nitrogen.

The various chemical features revealing that the water body has alkaline pH (x?=8.2 units) and can be categorized among alkaliphilous water bodies. High electrical conductivity value (x?=264.2μS/cm) puts the water body in mesotrophic condition. High total alkalinity value (x?=76 mg I-1) categorizes water body among nutritionally rich. High phosphorus value (x?=0.31 mg I-1) puts Bhoj wetland again into the eutrophic category while high nitrate nitrogen value (x?=0.67 mg I1) is being associated with accelerated eutrophication of water body. Over all study revealed that Bhoj wetland under eutrophic state.
