We used f.esh and bracki.h water shri.p (Desmoscari. tri.pi.osa and Palaemonetes af.i.anus), i. sedi.ent bi.assays to assess the toxi.i.y of.an i.dustri.l detergent contai.i.g hi.h levels of.ani.ni. surf.ctant (li.ear alkylbenzene sulphonate (LAS)). The Organi.ati.n f.r Economi. Cooperati.n and Development (OECD), # 218 di.ect sedi.ent toxi.i.y assessment was employed. The organi.ms were exposed to di.0}erent concentrati.ns (31.25, 62.5, 125, 250 and 500 mg/kg) of.the chemi.al (Neatex) i. repli.ate treatments. Percentage mortali.y was measured as the ecologi.al endpoi.t. Mean mortali.y and esti.ated lethal concentrati.n LC 50 values vari.d wi.h speci.s type, concentrati.n and exposure durati.n. The stati.ti.al vari.ti.n i. the observed mean mortali.y of.the test organi.ms i. the chemi.al and the control treatment shows that mortali.y may be i.duced by the ef.ect of.the chemi.als. The lethal concentrati.n (LC 50 ) was si.ni.0}cantly di.0}erent at levels of.p f.r the f.esh and bracki.h water experi.ents. Consequently, assessment of.water and sedi.ent quali.y as a result of.chemi.al pollutants was necessary f.r protecti.g some of.the more sensi.i.e benthi. i.vertebrates representi.g the major proporti.n of.the di.t of.many speci.s i. the Ni.er Delta ecologi.al zone.

Dunwoody mani.0}lds are an i.teresti.g class of.closed connected ori.ntable 3-mani.0}lds, whi.h are def.ned by means of.Heegaard di.grams havi.g a rotati.nal symmetry. They are proved to be cycli. coveri.gs of.lens spaces （possi.ly S3） branched over （1, 1）-knots. Here we study the Dunwoody mani.0}lds whi.h are cycli. coveri.gs of.the 3-sphere branched over two speci.0}ed f.mi.i.s of.Montesi.os knots.
