The.ne.d to asse.s the.quality status of the.Be.in Rive. prior to the.se.port de.e.opme.t was inhe.e.t to docume.t the.base.ine.of the.physicoche.ical parame.e.s of the.study stre.ch.

Managing e.trophication in Nige.ia Inland Wate.s

Journal of Wate. Re.ource.and Prote.tion 2013年第7期5卷 743-746页

作者： N. O. e.hunmwunse.A. R. Dirisu A. e. ogbeibu De.artme.t of Animal and e.vironme.tal Biology Faculty of Life Sciences University of Benin Benin City Nigeria

Re.e.tly in Nige.ia, cultural e.trophication is on the.incre.se.in wate. bodie.. Obse.vations from land use.around rive.ine.are.s are.pre.ominantly for farmland and e.plain the.high le.e. of phosphate.from runoff during the.rainy se.son. Incre.se. siltation, de.ore.tation, flooding, lumbe.ing activitie. and othe. land use.pe.turbation are.among the.cause. of e.trophication. Aquatic animals usually suffe. hypoxia and anoxia and the.ane.the.ic quality of wate. for re.re.tional activitie., like.swimming, boating and picnic is re.uce.. The.Fe.e.al Ministry of e.vironme.t (FMe.V) and Rive. Basin Authority of Nige.ia should e.sure.that all those.involve. in e.flue.t discharge.into wate. bodie. follow the.e.tablishe. frame.work and e.isting guide.ine.. Point source.and non-point source. of pollution should be.monitore. and the.adoption of mathe.atic mode. which de.cribe. the.ove.all nutrie.t runoff and the.catchme.t mode. suitable.for de.cribing the.ove.all transport of wate. and nutrie.t through the.rive. basin should be.e.courage. as practice. in Poland.
