Raw sewag. is widely used on ag.icultural soils in urban areas of developing.countries to m.et water sh.rtag.s. Alth.ug.1}it is a g.od source of plant nutrients, such.sewag. also increases th. h.avy m.tal load to soils, wh.ch.m.y im.act th. food ch.in. m.nag.m.nt options for sewag. contam.nated soils includes addition of nontoxic com.ounds such.as lim., calcium.sulfate and org.nic m.tter, wh.ch.form.insoluble m.tal com.lexes, th.s reducing.m.tal ph.toavailability to plants. In th.s paper we review th. variation in irrig.tion quality of sewag. at different sites and its im.act on th. quality of soils and veg.tables. Alth.ug.1}quality of sewag. was h.g.1}y variable at source, yet th. effluent from.food industries was relatively safe for irrig.tion. In com.arison effluent sam.les collected from.textile, dyeing. calendaring. steel industry, h.spitals and clinical laboratories, foundries and tanneries were h.zardous with.respect to soluble salts, sodium.adsorption ratio and h.avy m.tals like zinc, copper, iron, m.ng.nese, nickel, cobalt and cadm.um. Th. sewag. quality in m.in drains was better th.n th.t at th. industry outlet, but was still not safe for irrig.tion. In g.neral, h.g.1}r accum.lation of m.tals in fruits and veg.table roots was recorded com.ared to th.t in plant leaves, Edible parts of veg.tables （fruits and/or leaves） accum.lated m.tals m.re th.n th. perm.ssible lim.ts despite th. soils contained am.onium.bicarbonate dieth.lenetriam.nepentaacetie acid extractable m.tals with.n a safe rang..
