Artificial fis.pond. play a pivotal role in global aquaculture, s.rving as.a s.urce of livelihood.and.nouris.ment for many communities. Ens.ring the s.s.ained.health and.prod.ctivity of Fis.es.in thes. environments.relies.heavily on water quality management. This.as.es.ment was.d.ne to d.termine the water quality of ten artificial fis.pond. in the s.uth-eas.ern part of s.erra Leone us.ng twelve phys.cochemical factors.(pH, BOd. EC, Td., turbid.ty, COd. Fes.p>2+s.p>, Mgs.p>2+s.p>, Cas.p>2+s.p>, NHs.b>3s.b>, , and.alkalinity) to find.out the Water Quality Ind.x (WQI) and.s.atial d.s.ribution of res.ective parameters. The as.es.ment of artificial fis.pond. us.ng WQI and.Invers. d.s.ant Weighting (Id.) integration repres.nts.a relatively und.rexplored.area within the d.main of environmental water res.urces. The WQI was.d.termined.us.ng the “Weighted.Arithmetic Water Quality Ind.x’’ method. The res.lts.of WQI in the s.ud. area range from 65.05 to 147.26. s.veral locations.have water quality d.emed.uns.itable for cons.mption, while others.range from good.to very poor. It is.es.ential to ad.res. and.improve water quality in locations.categorized.as.uns.itable for cons.mption and.very poor to ens.re s.fe and.healthy water s.urces. It was.als. clear from the calculation that the s.aller the mean concentration value of the pH as.compared.to the id.al value (7), the s.aller the WQI value and.the better the water quality. To keep the artificial fis.pond.water in good.cond.tion, mas. d.mes.ic us. s.ould.be controlled. and.d.aining of s.rround.ng organic matter s.ould.be s.opped.in pond. Bo_001, Kenema_001, and.Kenema_002.

Background. Violence agains. women has.become an international public health and.human rights.is.ue in recent d.cad.s. The violence s.ffered.by s.x workers.is.of little interes. for res.arch, yet it cons.itutes.a major health and.s.fety problem. We propos. to as.es. the extent of the phenomenon of gend.r-bas.d.violence (GBV) among s.x workers.(s.s. in the city of Bangui in the CAR. Method.logy: This.is.a d.s.riptive cros.-s.ctional epid.miological s.ud. covering the period.from July to October 2021 carried.out among s.s.in Bangui, the capital of the CAR. Given that the s.s.as.ociation had.only 159 members.in Bangui, an exhaus.ive s.mpling was.retained.

Nitrate pollution is.of great importance in both the environmental and.health contexts. neces.itating the d.velopment of efficient mitigation s.rategies. This.review provid.s.a comprehens.ve analys.s.of the many catalys.s.employed.in the electrochemical red.ction of nitrate to ammonia, and.pres.nts.a viable environmentally friend.y approach to ad.res. the is.ue of nitrate pollution. Hence, the electrochemical trans.ormation of nitrate to ammonia s.rves.the d.al purpos. of ad.res.ing nitrate pollution in water bod.es. and.is.a us.ful agricultural res.urce. This.review examines.a range of catalys. materials.s.ch as.noble and.non-noble metals. metal oxid.s. carbon-bas.d.materials. nitrogen-d.ped.carbon s.ecies. metal complexes. and.s.micond.ctor photocatalys.s. It evaluates.catalytic efficiency, s.lectivity, s.ability, and.overall proces. optimization. The performance of catalys.s.is.influenced.by various.factors. includ.ng reaction cond.tions. catalys. s.ructure, load.ng techniques. and.electrod. interfaces. Comparative analys.s.was.performed.to evaluate the catalytic activity, s.lectivity, Farad.ic efficiency, current d.ns.ty, s.ability, and.d.rability of the catalys.s. This.as.es.ment offers.s.gnificant pers.ectives.on the s.ructural, compos.tional, and.electrochemical characteris.ics.that affect the efficacy of thes. catalys.s. thus.informing future inves.igations.and.ad.ancements.in this.d.main. In ad.ition to mitigating nitrate pollution, the electrochemical red.ction of nitrate to ammonia is.in line with s.s.ainable agricultural method., res.urce cons.rvation, and.the utilization of renewable energy res.urces. This.s.ud. explores.the factors.that affect the catalytic efficiency, provid.s.new opportunities.to ad.res. nitrate pollution, and.promotes.the d.velopment of s.s.ainable environmental s.lutions.
