| Article Name : | | | EFFECT OF HEAVY METAL ON AQUATIC ALGAE AND INFLUENCE OF VERMIWASH ON ALGAL GROWTH | | Author Name : | | | Sapna R.

The use of bioassays for toxicity assessment, based on growth inhibition in algae is described and effect of vermiwash on algal growth is also observed. To overcome the toxic effect of metal use vermiwash, an organic liquid fertilizer. Vermiwash plays an important role in the plant growth and development. The interactive effect of metal ions namely Copper, chromium and Lead has been studied under controlled conditions on the photosynthetic green alga Scenedesmus bijugates over the exponential growth. In the present work describes algal growth is decreases if the metal ion concentration increase and reverse result found in case of vermiwash. | | Keywords : | | |
