The present investigation in the Tiruvannamalai region is about high fluoride contamination of groundwater samples from bore wells and open wells. About 75% were found predominantly containing content greater than acceptable limit 1.5 mg/L ranges 1.51 - 2.00 (23%), 2.01 3.00 (36%) or equal to 3.01 (16%) as per WHO. other water quality parameters within permissible Taking sources into consideration, non carcinogenic risk due concentration revealed that teen aged (98%), Children (92%) Infant...
This study evaluated bioelectricity generation by using kitchen garbage (KG) and bamboo waste (BW) as a solid management option microbial fuel cell (MFC) method. The nutrient content [nitrogen, phosphorus potassium (NPK)] of the by-products were also analyzed assessed for their potential use soil amendment. A one-chamber MFC was used in laboratory experiments both KG BW. data-logger recorded voltage every 20 mins at constant room temperature 25°C over 45 days. trend different two organic...
Pollution of rivers is mainly caused by anthropogenic activities such as discharge effluent from industrial facilities, maintenance sewage/effluent treatment plants, and dumping solid waste on river banks. This study dealt with the pollution issues Cooum River in well-known city Chennai South India. Water samples 27 locations were collected analyzed for 12 elements, including Ba, B, Al, well heavy metals Pb, Cr, Mn, Fe, Co, Ni, Cu, Zn, Cd. The showed levels these elements that exceeded World...
Drainages are pulses which in turn help us to understand the ongoing process hill ecosystem. The Kalrayan is known for its dissected terrain condition, rich biological diversity and depletion of natural resources. Therefore, a study on quantitative geomorphometry was carried out Hills, Eastern Ghats, Tamil Nadu, using Indian remote sensing 1D LISSIII satellite data. area divided into 36 watersheds total 1158.4 km2. It covers upper part Vellar basin. linear, aerial relief aspects different...
Wastewater treatment plants (WWTPs) in South Africa, like is the case for most WWTPs around globe albeit capable of removing substantial quantities microplastics (MPs) and fact, treatments become ineffective those plastic particles less than 100 µm. As a consequence, receiving water bodies which final effluent discharged becomes highly polluted. The present research devoted to analysis pervasive MPs wastewaters plant located Gauteng Province, Africa using Pyrolysis – GC-TOF-MS. Based on...
Arsenic (As) is a toxic metalloid, having both properties of metal and non-metal. Boron (B) nonmetal, essential micronutrient for plants growth development but its excess can be to with various levels. In this study arsenic, boron salt resistant bacteria were isolated from desert soil, Mongolia. The bacterial screening was carried out by serial dilution method. One hundred colonies screened initially using (2 mM) arsenic containing LB agar medium. From population, 10 isolates selected based...
The study of PM2.5 and NO2 has been emphasized in recent years due to their adverse effects on public health. To better understand these pollutants, many studies have researched the spatiotemporal distribution, trend, forecast, or influencing factors pollutants. However, rarely combined generate a more holistic understanding that can be used assess air pollution implement effective strategies. In this study, we analyze Nagasaki Prefecture by using ordinary kriging, pearson's correlation,...
The fluoride adsorption by Electro-Generated Adsorbents (EGA) was briefly and recently shown. In this paper, the preparation of a particular EGA its characteristics are presented. For first time, one deeply investigated showing that regeneration material leads to an efficient process which better than electrocoagulation one. adsorbent called EGANaCl prepared electrolysis in NaCl electrolyte with aluminum electrodes characterized X-ray Diffraction (XRD), scanning electron microscopy (SEM)...
