water is a unique natural resource among all sources available on earth. it plays an important role in economic development and the general well-being of the country. this study aimed at using the application of water quality index in evaluating the ground water quality innorth-east area of jaipur in pre and post monsoon for public usage. total eleven physico–chemical characteristics; total dis...

Present study aims to unravel the hydro geochemical interaction of sediment and water of Saheb bandh lake, West Bengal, India with an emphasis on heavy metal assessment. Lake water belongs to Ca2+–HCO3− type hydro geochemical faces and water-rock interaction primarily controls the lake water chemistry. Based on different Hydro chemical characteristics it is suggested that silicate weathering is...

To evaluate the impact of environmental factors on the occurrence of environmental mycobacteria, viable counts of mycobacteria were measured in samples of brook water collected from 53 drainage areas located in a linear belt crossing Finland at 63 degrees north latitude. The numbers of mycobacteria were correlated with characteristics of the drainage area, climatic parameters, chemical and phys...

abstractbackground and objectives:anise (pimpinella anisum l.) is an annual medicinal plant which belonged to the apiaaceace family. grain is the most important organ to produce essential oil of anise. in order to produce medicinal plant it is necessary to determine the environmental factors under which they give higher yields and better quality (23). in medicinal plants, balanced fertilization...

Abstract In this research, to review the role of geomorphological phenomena has been discussed in the change of chemical quality of water in the part of geography the north east of the country. Geomorphological phenomenon discussed in this research is marly hills that is result of volcanic-sedimentary activities of geological tertiary and is discussed the role of chemical effects this hills ...
