Toxicity Evaluation of Hasdeo River Water on Seed Germination and Amylase Activity in Vigna radiata L

River water is a very important natural resource of water for meeting the requirements of various sectors in the world and for this reason cannot be looked upon in isolation [1]. The Hasdeo River is second largest tributary of the Mahanadi River system in East Central India. Hasdeo River in Chhattisgarh is influenced by the various problems imparted by excessive industrialization, urbanization and rapid agricultural usage similar to other riverine system. The water quality of Hasdeo River has been deteriorating due to loss of their selfpurification capacity with the addition of metal and organic pollutants day by day [2]. This pollution not only affects water quality, but also directly or indirectly threats human health, economic growth and social prosperity. In developing countries like India mostly rivers are polluted. In India, mostly farmers irrigate their crops with river water having contaminants like high amount of organic compounds and heavy metals due to unavailability of alternate sources of irrigation that ultimately affects biochemical response of crop plants and yield [3,4]. The evaluation of metal toxicity and organic pollutants present in the river water are immensely important to determine their phytotoxicity, before their possible utilization in agriculture and human consumptions. On other hand, concern about the adverse effect of polluted Hasdeo River water has not arisen until the last decade. Hence, this study deals with the toxicological evaluation of Hasdeo River water by using seeds of Vigna radiata L. in terms of seed germination, seedling growth and amylase activity for environmental safety. This study was extended to analyze chemical texture of Hasdeo River water for validation of this toxicological behavior.
