Abstract: The highly spreadable disease named as Corona Virus Disease and abbreviated as COVID-19 as first recognized in December 2019 in Wuhan city in China. The severity of this virus largely destroyed the world health structure leading to death. Human development is completely influenced by this uncontrollable spreading of virus.The world economy is going through a crucial period due to COVID-19 situation. The economic growth has been locked in the claws of Corona. The psychological wellbeing,quality of life and economic instability puts the globe in a puzzle of.

Abstract: Natural processes and human activities including anthropogenic sources may increase the level of physicochemical qualities of ground and surface water in environment. Physico – chemical qualities of water sources within Okposi Okwu and Uburu area were investigated using standard technique to ascertain if the water samples were safe for drinking. The qualities measured include temperature, pH, turbidity, total dissolved solid (TDS), electrical conductivity (Ec), nitrates (NO3¯), sulphate (SO4¯2), phosphate (PO4¯3), chloride Cl¯, sodium (Na), lead (Pb), copper (Cu), cadmium (Cd), chromium (Cr), nickel (Ni), arsenic (As) and cyanide (CN). Fresh water quality was observed in all the samples; with neutral pH recorded in Atta stream, Asu river, borehole water samples in both...

Abstract: The river Salandi, from its source of origin to Tinitaraf ghat travels 134kms of long distance through forest area, mining and industrial belt, urban area, agricultural area and finally meets with the Bay of Bengal at Dhamara port. The river during its course of journey receives different hazardous pollutants from different places . In this work, water samples collected from nine different monitoring stations during rainy, post rainy, winter and summer seasons in the year 2015 and 2016 have been analyzed by using the standard procedures available in APHA, 2012 to study the sixteen physico-chemical and biological parameters and out of which mean and standard deviations (S.D) of twelve parameters have been calculated and computed for comparative study of water quality through Weighted.....

Abstract: The peculiarities of obtaining carbon ecosorbent from rice husk for strong binding of heavy metals (Cd (II), Cu (II) ions) and their detoxification in soils have been studied. It is established that the modification of biocarbon can significantly improve the structural-porous and ion-exchange properties of the material, which increases its sorption capacity. The obtained results show that the modified ecosorbents from rice husk have a fairly high exchange capacity for Cu (II) and Cd (II) ions. Sorption binding of ecosorbents reaches values of 80-90%. The introduction of such an ecosorbent into the soil leads to a strong binding of toxic heavy metals in stationary sulfide forms, prevents migration, which prevents their accumulation in plants. Sulfur-containing ecosorbents from pyrolyzed plant raw materials are environmentally friendly and have the potential for detoxification of heavy metals in the root zone of the soil.

Abstract: The upsurge in anthropogenic activities in the littoral communities of Akwa Ibom State has taken a heavy toll on the ecological equilibrium of the entire natural ecosystem of the region. Consequently, depletion of the groundwater resources is gradually assuming an alarming proportion. To make matters worse, there is a spectre of hydrochemical events in the subsurface also contributing in no small measures to the groundwater quality degradation. Given this scenario, it has become imperative that groundwater quality in these new eco-nomically active communities be subjected to regular quality tests in order to determine the extent to which this all-important resource is being influenced by both human and natural activities in the zone. Hence the study investigated the groundwater quality in the afore-mentioned communities with a view to determining its usabil-ity for domestic, agricultural, industrial and other water-based applications. Groundwater samples were evalu-ated based on the World Health....

Abstract: The present study is that the application of Sequencing Batch Reactor (SBR) and Sequencing Batch Biofilm Reactor (SBBR) for treating the domestic wastewater. The SBBR utilized in this study contained biomass immobilized in inert support material (polyurethane foam cubes) also as suspended biomass while in SBR only suspended biomass was used. The SBR was operated for long duration and from day 125 onwards the effluent phosphorus concentration reduced to less than 4 mg/l (80% P uptake). Denitrification was observed from day 120 onwards within the anaerobic phase while nearly complete nitrification was observed in subsequent aerobic phase with effluent ammonia nitrogen.....
