“…In direct effect, it can help to break the DNA double strands while the indirect effects are the generation or reactive oxygen species. The level of radionuclides presents in soil, water, air and food had been researched [12,13] using different methods to determine the radon concentration but the radon concentration of the selected offices in Bells have not been determined. Therefore, it is expedient to carry out this research work.…”

Radon, a radioactive gas that emanates naturally from the earth crust is accountable for about 50% of the effective dose of ionizing radiation received by humans. Most radon susceptiveness occurs in homes and work places, it comes from the natural disintegration of uranium in soil, rock and water and escalate to the air that we breath, hence it is important to monitor the actual level of exposure in most buildings. This work analysed the indoor radon concentration in air at twenty different offices of different building at Bells University of Technology using Rad7 detector. The mean measured radon concentration ranges from 0-56.7 Bq/m3 for all the study locations. The mean absorbed dose, equivalent dose and effective dose were calculated with the radon concentration which are 0.152 mGy/y, 3.045 mSv/y and 0.365 mSv/y respectively. The results obtained are below the world set limit as recommended by International Commission on radiological protection, except for office 7 which slightly exceed the recommended limit. Thus, the study concluded that good ventilation is very important in the reduction of radon concentration level in our work places.

“…Delhi constitutes less than 1% of the total catchment of Yamuna but contributes more than 50% of the total pollutant load which is discharged into the river over the urban stretch of 22 km between Wazirabad and Okhla barrages (Daniel, 2007;MOEF, 2013;Paul et al, 2014). The industrial effluents, domestic wastes, urban and agriculture runoff are full of suspended solids, colored wastes, toxic substances and organic matter (Kaushik et al, 2009: Suthar et al, 2010Mishra et al, 2014;Rout, 2017;Mishra et al, 2021). The organic pollutants from industrial waste water from pulp and paper mills, textiles and leather factories, steel foundries and petrochemical refineries are the major cause of illness to aquatic flora and fauna, societies dependent on the same, where regulations do not necessarily protect the people from such industrial outflows (Chaterjee et al, 2002;Chatterjee et al, 2010;Agarwal and Saxena, 2011;Chaurasia and Tiwari, 2011;Jena et al, 2013;Angiro et al, 2020).…”

Water is the main source of life. The natural aquatic resources are the major habitat for a large group ofindividuals including nonchordates to chordates. As water are the most abundantly available and occupying2/3 of the Earth and required by all kinds of life. Therefore, quality of water is of vital concern for mankindsince it is directly linked with living beings in term of habitat, sustainability, economy and human welfare.The current study is designed to work out the quality characteristics and their oscillations in physico-chemicalattributes of river Yamuna water in the district Bhaghpat, Uttar Pradesh, India. The investigation wasconducted during July, 2019 to June, 2021 and the sample was analysed in the Bioanalytical Laboratory,Department of Biotechnology, MM (DU), Mullana-Ambala (HR), India. The effects of monthly and seasonalpossible attributes including discharge of industrial effluents and natural calamities for the spatialfluctuations in the hydrobiological parameters of river Yamuna water was assessed through the advancednumerical tools. The monthly physicochemical attributes showed the seasonality biased trends during thestudy. The mean value Â± SE of water temperature (oC), dissolved oxygen (mg/l), alkalinity (mg/l), acidity(mg/l) and hardness (mg/l) was recorded as 23.7Â±1.3 oC, 4.2Â±0.22 mg/l, 100.09Â±4.8 mg/l, 44.55Â±4.38 mg/l and 550.8Â±30.3 mg/l respectively during July 2019 to June, 2020. However, the physicochemical attributesduring July 2020 to June, 2021 reflected augmented trends for water temperature (24.2Â±1.27 oC), dissolvedoxygen (5.1Â±0.16 mg/l), alkalinity (103.95Â±5.25 mg/l). On the contrary, acidity (39.92Â±2.63 mg/l) andhardness (522.48Â±39.82 mg/l) recorded decline. The observation reflected the requirement of urgent andsystematic management strategies to overcome these invisible scarce and conserve the natural quality ofthese water resources.

Greater NOIDA evolved from 1991 with 101 villages to 2020 with 293 villages. This is an ideal case of rural to urban transformation in the immediate past. This transformation led to a decrease in recharging natural surfaces and an increase in impermeable surfaces. Along with the reduction in recharge areas, an increase in population has necessitated more and more extraction of groundwater resulting in an imbalance of water extraction and recharge. The result is depletion of groundwater levels in this area. The area is part of the wide Indo-Gangetic alluvium with sand, silt and clay layers resting on quartzite’s of Delhi Super Group. Geomorphological map prepared using digital elevation models of the area shows older and younger alluvial plains and active flood plains of the river Hindan. Time series analysis of key land use land cover classes shows that recharge areas were reduced from 77 % to 30 % from 2005 to 2019 and impervious surfaces have increased from 19 % to 65 % for the same period. Aquifers of the area are both phreatic and semi-confined. The aquifer parameters estimated through step drawdown test and long duration aquifer performance test indicates that the average coefficient of transmissivity of the area is 1752 m2/day and the average coefficient of storage is 4.84 x 10-4. Discharge of the wells shows a yield of 8 to 16 lps for a drawdown of 3 to 6 m. An attempt has been made to know the behaviour of groundwater levels during the same period as that of land use land cover. The results indicate a 74 % depletion in groundwater levels with an average annual depletion of 21 %. An interrelationship between urban growth and groundwater levels has been established in this study. This analysis indicates that as agriculture declined water levels also depleted and have a positive correlation of 0.852. On the contrary, as the built-up increased water level has depleted hence have a negative relationship with a correlation coefficient of -0.851. To make it a sustainable resource, these overexploited aquifers need careful participatory management by communities, Scientists, and policymakers.
