“…The high concentration of 40 K in coal is due to bitumen rocks of plant origin having compounds that bind to potassium. Plants that are converted to coal use potassium as an essential element involved in functions such as nutrition, enzyme activation, osmotic regulation, growth, and plant development so that potassium levels in plants have a significant quantity, about 25% of the total mineral (Gupta et al, 1998;John et al, 2022).…”

Environmental radioactivity analysis has been carried out to determine the level of environmental radioactivity and the potential radiological hazards at Tanjung Enim’s coal mine. Gamma spectroscopy method has been carried out to identify radionuclides and their types of activity. The results of radionuclide concentration are used to determine the radiological hazard index and become input data for the Residual Radioactivity Onsite 7.2 application to determine the dose rate and long-term cancer potential received by workers in coal mines. The results obtained for the average concentration of radionuclide activity in coal samples are 226Ra, 232Th, and 40K are 72.468 Bq/kg, 86.905 Bq/kg, and 1802.049 Bq/kg, respectively. While the soil samples 226Ra, 232Th, and 40K respectively 79.205 Bq/kg, 100.209 Bq/kg, and 1443.275 Bq/kg. The radionuclide concentrations of both samples exceeded the UNSCEAR and worldwide reported averages for coal and soil. The average radiological hazard index for coal samples, namely Raeq, Hin, and Hex, was 335.500 Bq/kg, 1.102, 0.906, respectively. While the soil samples were 333.636 Bq/kg, 1.115, and 0.901, respectively. The index parameter is already lower than the UNSCEAR recommendation except for Hin, so there is a potential radiological hazard in internal pathways such as respiratory and digestive organs for mining workers. The total annual effective dose rate based on 5 RESRAD-Onsite 7.2 pathways, namely external gamma, inhalation, radon, soil ingestion, and drinking water, is 1.675 mSv/year, exceeding the dose limits determined by ICRP, 1 mSv/year. The ELCR is 6.625×10-3 which exceeds the UNSCEAR recommendation, 2.4×10-4. Based on the results, it is necessary to intervene in the mining environment of the Tanjung Enim’s coal mine.

“…In India, the use of saline groundwater for aquaculture has been identified as a high-priority research area (Allan et al, 2009;Sharma & Singh, 2015). For reducing the use of freshwater and increasing the use of saline groundwater, various technologies like aquaponics using freshwater (John et al, 2022;Nuwansi et al, 2017Nuwansi et al, , 2020Nuwansi et al, , 2021Shete et al, 2013Shete et al, , 2015Shete et al, , 2017 and aquaponics using saline groundwater (Thomas et al, 2019(Thomas et al, , 2021 for various fish in aquaculture. Furthermore, the biofloc technology is also aimed at reducing the use of water for aquaculture (Ahmad et al, 2019;Ezhilarasi et al, 2019;Nageswari et al, 2020Nageswari et al, , 2022.…”

Efficient water budgeting for various species will help in establishing database for providing practical solutions to the aquaculture sector's water crisis. Hence, a 90‐day study was conducted to evaluate the requirement of water for culture of Penaeus vannamei in inland saline groundwater. The earthen grow‐out ponds (0.1 ha) were stocked with postlarvae of P. vannamei (2.50 ± 0.01 g) at three different stocking densities, that is 30/m2 (T1), 45/m2 (T2) and 60/m2 (T3) respectively. The total quantity of water supplied and evaporation and seepage losses were measured on a daily basis. The rainfall and surface runoff were measured in the event of rainfall. The water quality parameters were analysed once in 10 days and were found to be within the permissible limit. The mean total consumption of water for T1, T2 and T3 was 2093.33 ± 6.66, 2099.30 ± 3.33 and 2092.96 ± 5.77 m3 respectively. The survival and yield of P. vannamei in treatments T1, T2 and T3 were 80.49 ± 0.61%, 72.06 ± 0.74% and 68.70 ± 1.45%; and 283 ± 1.53, 322 ± 3.46 g and 311 ± 3.79 kg respectively. The consumptive water use index was significantly less (p > 0.05) in T2 (6.53 ± 0.07 m3/kg) followed by T3 (6.74 ± 0.08 m3/kg) and T1 (7.41 ± 0.04 m3/kg). The water productivity of P. vannamei was significantly higher (p < 0.05) in T2 (0.153 ± 0.002 kg/m3) followed by T3 (0.148 ± 0.002 kg/m3) and T1 (0.135 ± 0.001 kg/m3). Considering the total quantity of water used and the shrimp produced from the earthen grow‐out ponds using inland saline groundwater, a stocking density of 45/m2 and a water budget of 6.53 m3/kg production of shrimp could be recommended as optimum.
