Groundwater is the only source of water of the Swami Vivekananda Airport Raipur, and it faces water crisis when the groundwater level decreases. In this scenario, Rain Water Harvesting (RWH) can contribute considerably to tackle these problems. Rainwater treatment systems can be installed at different potential locations in study area based on their physical site conditions such as slope, elevation etc. The airport has 38955.62 Square meters rooftop area out of 2.108 Square Kilometres total area, water collected from the rooftop will fulfil approximately 30% of the total daily demand of the airport. Apart from this airport is properly designed drainage system storm water is collected and separated into three potential zones. Zone I, II and III having area 0.2393, 0.4307 and 1.4382 sq. Kms respectively, which produce a different runoff amount based on maximum daily rainfall. Storm water is treated by Slow Sand Filter (SSF) of rate of 200 litres per hour per square meter and stored under design capacity, size and number of treatment unit depend on the maximum discharge at their respective zones. Treated rainwater is utilized for recharge purpose through the recharge trench when excess water comes from the rainwater tank.

Predominant form of N in aerobic soils is nitrate (NO3-) while ammonium (NH4+) exists in anaerobic soils. Development of cultivars with improved NH4+ or NO3- use efficiency by harnessing inherent significant variability for NUE can be an important approach. Considering these facts, the present study was established with one hundred twenty two and selected thirty two recombinant inbred lines (RILs) of two indica genotypes, Danteshwari × Dagad deshi under three nitrogen forms and three environments. The trend analysis of NH4+-N and NO3--N dynamics revealed that NH4+-N concentration persisted more under anaerobic condition and NO3--N concentration under aerobic conditions. Three way-ANOVA showed high level of significance for variance components (G, N, E) and their interactions effects (GXN, GXE, NXE, EXNXG) for yield and NUE and their component traits. Mean performance of genotypes depicted higher values for agronomically important traits i.e. yield and NUE under NH4+ as compared to NO3--N and N0. The phenotypic and genotypic data was statistically analyzed for QTLs identification for yield and NUE traits. A total of 58 QTLs conferring the corresponding five traits were detected under three N forms and two environments. We also investigated the different members of AMT (Ammonium transporters), NRT (Nitrate transporters), GS (Glutamine Synthetase) and GOGAT (Glutamate Synthase) genes, involved in NUE and analyzed the expression pattern of each gene using gene-specific primer in young rice seedlings. Collectively, OsGln1;1, OsGln1;2, OsGln1;3, OsGln2, OsGlt1 and OsGlt2 manifested different and reciprocal responses to nitrate and ammonium supply. The activity of enzymes NR, NiR, GS and GOGAT was significantly affected by NH4+and NO3- treatment.

The long exposure of arsenic can cause hazardous health effects like skin cancer, lung cancer as well as heart diseases. Conventional methods for monitoring arsenic level is often strenuous and require highly skilled personals to perform the measurements, thus there is a need to develop a simple and cost- effective techniques for quick and continuous monitoring. Paper-based approach for detecting the arsenic is a low-cost, non-instrumental method and provides on-site detection of water contaminants. In this study a rapid, simple and affordable method for arsenic detection was developed. This methodology involves the generation of arsine gas inside the analysis system that reacts with the silver nitrate present on the paper analytical device (PAD). This reaction between silver nitrate and arsine gives a colored product that was detected by scanning the colored intensity with image processing software. The iron oxide nanoparticles act as a reducing agent that causes the generation of arsine gas from arsenic. These nanoparticles were synthesized through green technology by using henna extract. The whole reaction takes place in the glass vial with the rubber cap on it at which the PAD was placed. Experimental parameters like concentration of reducing agent, silver nitrate and reaction time were evaluated that affects the performance of the analytical process.
