摘要：The present study reports effect of domestic wastewater from Bhilai Steel Plant on a macrophyte Calocacia sp. In the normal condition the size and shape of the leaves, root and stem was normal. But in the contact of effluent, the size and shape of the leaf , root and stem is larger. Likewise in normal condition and effluent condition the concentration of phosphate iron, calcium and magnesium are different. In normal condition, plant height is 35 to 45cm whereas with the effluent effect, the height of the plant is 96 to 99cm long Variation in the parameter of effluents like temperature, pH, total dissolved solid, free carbon dioxide, chloride, dissolved oxygen, biochemical oxygen demand, chemical oxygen demand, phosphate, sulphate, nitrite, nitrate, ammonia, magnesium, calcium, iron and phenol effects the shape, size and the concentration level of the plant.
