Comparative eco-physiological potential of a submerged and a free floating aquatic plant to treat domestic wastewater

Domestic wastewater treatment has become a remarkable aquatic environmental problem for all over the world. Due to non-availability of cheaper methods and higher cost of treatment plants, municipalities are diverting untreated domestic wastewater in to aquatic bodies like ponds and lakes, where it is causing eutrophication due to higher concentration of nutrients and leads water unhygienic to use. Present research experimented by culturing Hydrilla verticillata, and Pistia stratiotes seprately in domestic wastewater for subsequent seven days over the year. The quality of domestic wastewater before and after the treatment/culture was evaluated by analyzing physico-chemical parameters of domestic wastewater followed by APHA-AWWA-WPCF (1980).The results of physico-chemical analysis of domestic wastewater and estimation of net primary productivity of experimental aquatic plants after the culture have indicated an improvement in water quality and increase in biomass. Both the aquatic plants proved to be efficient in treatment of domestic wastewater and their increased weight in culture has potential value in biomass generation.It is concluded that both the aquatic plants perform significant potential to remove nutrients from domestic wastewater and also showed seasonal variation for the purpose

Comparison of changes in sugar contents in the cotyledons of Trigonella and Tamarindus

Fleshy cotyledons serve as the major storage organ in most non-endospermic legumes. Cotyledons serve as major storage organs with protein and carbohydrates as the major food reserves. Reserve food is broken down by the formation of various types of hydrolases (e.g., amylases, proteases, nucleases, lipases, etc.). In germinating seeds, the starch degraded for the formation of sugar, it was found that at the level of starch degradation, the accumulation of sugar in cotyledons of both Trigonella and Tamarindus was quite prominent. It was marked that sugar was the hydrolytic product of starch. It accumulated in the cotyledons along with the subsequent degradation of starch. In most of the cases it showed a decline in its level due to its translocation into the axis which acted as a link

Treatment of domestic wastewater by potential application of a submerged aquatic plant Hydrilla verticillata Casp

All over the world wastewater pollution is common. Untreated municipal wastewater posing eutrophication, where water is enriched with nutrients and unhygienic to use. Control of eutrophication is burning issues for aquatic sites around the world. In such a state, remediation of nutrients by aquatic plants is remarkable for municipal wastewater treatment. Present study was conducted by off-site experiment, where Hydrilla verticillata Casp was cultured in a tub for subsequent seven days over one year. Second one of the tub was used as control. The quality of domestic wastewater was assessed before and after the experiment by analyzing physicochemical parameters following APHA-AWWA-WPCF-1980. The results of the present experiment revealed the significant improvement in the quality of municipal wastewater, as indicated by the decrease in values  of most physicochemical parameters studied, except pH,  Dissolved oxygen and plant biomass. That showed efficiency and potentiality of aquatic plant for the purpose.&nbsp

Study on growth, potential utility and N.P.P. of a submerged aquatic plant Hydrilla verticillata Casp.

Hydrilla verticillata Casp is a rooted submerged aquatic plant belonging to the family Hydrocharitaceae. It is distributed in aquatic bodies over the world. Hydrilla verticillata Casp affect the aquatic system positively or by negatively based on their density in aquatic bodies. Specific growth pattern, Physiology and mode of vegetative propagation etc. help Hydrilla verticillata Casp to adopt in various types of fresh water environment. Aquatic plants are important for maintaining life system in water bodies and also useful for nutrient recycling. A wide ecological impact of aquatic plants in water has been recorded by the researchers in the world. The aim of the present study was to examine the growth and estimation of NPP of Hydrilla verticillata Casp in an artificial water tank and plastic tubs respectively. Findings of the experiments are discussed furthermore

Medicinal plants used as antidotes in northern part of Bastar district of Chhattisgarh.

The present study has been done on the traditional knowledge of the plants, widely used as Antidotes amongst the local peoples of north Bastar region of Chhattisgarh. The survey was conducted in north Bastar region of the Chhattisgarh state and information was collected from people about the plants used as Antidote against the treatment of Snake/Scorpion bite. The study revealed total of 29 species of plants belonging to 20 families widely used as antidote in northern part of Bastar. The plants species were documented on the basis of their phytochemicals and use in Antidote. Maximum of (03) species were belong to the family Asclepiadaceae and (02) each to family Fabaceae , Acanthaceae and Liliaceae. 75.86 % of the observed plants were found to be propagated by their seeds while, 6.89 % by rhizome, 10.34% by stem cutting and 3.44 % each by other plant parts like tuber and bulb. Study also revealed that plants yielding antidotes are propagated and conserved by the local people of northern region of Bastar as they are vital in treatment of snake/scorpion bite.&nbsp

Special Reference to Handicraft and Cottage Industry in Odisha

Any country\u27s environmental problems are related to the level of its economic development, the availability of natural resources and the lifestyle of its population. In India, the rapid growth of population, poverty, urbanization, industrialization and several related factors are responsible for the rapid degradation of the environment. Environmental problems have become serious in many parts of the country, and hence cannot be ignored.  80% of the total population of Odisha, a state of Eastern India depends on agriculture. But most of them are small and marginal farmers. 48% farmer\u27s households are indebted. The state, in reality, is the second poorest state in India today, next only to Bihar. Industrialization is the only alternative to develop the economic status of the state but the darker side of it is environmental pollution. Hence if the growth of industry can be accelerated along with environmental protection then a balance can be maintained. So this paper examines the growth of cottage industries in the state of Odisha through different statistical analysis as this is an eco-friendly industry and simultaneously a prospective area for the growth of indigenous talent
