The Aspergillus Niger bio augmentation influence on COD and protein disposal in domestic effluent under wastewater requirements have been considered. The sewage simulation bioreactor has been operating at a hydraulic retention time of 17-hour, 20°C, and PH 7.8 beneath aerobic circumstances. While A. Niger has been bio augmented, forty-five percent to seventy-two percent of COD has been released in comparison with twenty-eight percent to forty-eight percent disposal of COD in the controlling in the identical time. Whole protein disposal of sixty-six percent co while A. Niger has been bio-augmented in comparison by 29.7 percent in the controlling. Concerning enzymatic actions, we have attended which since the bio augmented strategy biomass attention has been more than the controlling the enzymatic actions have been high. This investigation is a primary study on swage transfer underneath transient situations by A. Niger and displayed the capability of A. Niger for removing both COD and protein underneath real situations. A. Niger bio augmentation underneath sewage situations can be an alternative for wastewater therapy by a valorization of fungal waste biomass.

Abstract
Because pesticides are ubiquitous and focused on the food chain, they are a substantial source of possible environmental danger to humans and animals. The highest extremely hazardous herbicides to be launched in 60 years ago is paraquat (1,1'-dimethyl-4,4'-bipyridylium dichloride). Although most nations ...

Because pesticides are ubiquitous and focused on the food chain, they are a substantial source of possible environmental danger to humans and animals. The highest extremely hazardous herbicides to be launched in 60 years ago is paraquat (1,1'-dimethyl-4,4'-bipyridylium dichloride). Although most nations have prohibited or severely limited the use of paraquat (PQ), it is still used in others, particularly in Nigeria. As a result, the present study used a spectrophotometric method to look for PQ in some vegetables, crops, and fruits in Abeokuta that are commonly consumed. The presence and amounts of PQ residues were assessed in 150 samples of various vegetables, crops, and fruits (harvested at Fadama field of the University of Agriculture, Abeokuta). PQ residues were detected in Talinum triangulare, Corchorus olitorius, Amaranthus caudatus, Cratylia argentea, Capsicum frutescens, Lycopersicum esculentum, Raphanus sativus, Zea may, and Dioscorea alata at 0.130.02, 0.27+0.02, 0.06+0.01, 0.10+0.03, 0.15+0.03, 0. Using this technique, no paraquat residues were found in M. paradisicica or C. papaya. At 0.05-1.0 ppm fortification level, the technique yields a mean recovery of over 80% and is reproducible with a total coefficient of variation of 8.0 percent (n=10). All residual levels found were under the PQ tolerance or pesticide maximum limits.

Living in poverty-driven communities suffering from food insecurity that is escalated as a result of sub-standard exploitation, fishery resources, and other environmental challenges, small-scale Nigerian artisanal fishers have dominated the fisheries sub-sector. Sadly, environmental changes have reduced Kainji Lake's inflow levels from 393,369m/cu3 in 1994 to 307,231m/cu3 in 2011, accordingly reducing the fish yield by 24025 metric tons in the same period, which has put innumerable Nigerian beneficiaries livelihood at serious risk. The study aimed to devise and propose an adaptive strategy model using the concept of sustainable livelihoods approach. This study mainly depended on distributing questionnaires among thirty fishing communities as the data collection method and provided supplementary data from officials. The results indicated that a set of four livelihood activities yields optimum outcomes. This paper also discusses its implications.
