An alloy of A1-8wt% Si.0.8wt% Fe was cast i. a metalli. di., and i.s mi.rostrucmral changes due to Ti.B refi.er and Sr modi.i.r addi.i.ns were studi.d. Apart from usual refi.ement and modi.i.ati.n of the mi.rostructure, some mutual i.fluences of the addi.i.es took place, and no mutual poi.oni.g effects by these addi.i.es, i. combi.ed form, were observed. i. was noti.ed that the di.ensi.ns of the i.on-ri.h i.termetalli.s were i.fluenced by the addi.i.es causi.g them to become larger. The needle-shaped i.termetalli.s that were obtai.ed from refi.er addi.i.n became thi.ker and longer when addi.g the modi.i.r. i. was also found that a-Al and eutecti. si.i.on phases preferenti.lly nucleate on di.ferent types of i.termetalli. compounds. The more i.on content of the i.termetalli. compounds and the more changes i. thei. di.ensi.ns occurred. Formati.n of the shri.kage porosi.i.s was also observed.

A number of speci.s （organi. and i.organi.） i. ai.borne parti.ulates cause the toxi.i.y to li.i.g bei.g. The potenti.l of i. vi.ro test methods were explored for toxi.i.y assessment of trace toxi. elements （i.organi. speci.s） present i. ambi.nt ai. on human bei.g （lungs）. A year long sampli.g of ai.borne parti.les （PM2.5） was carded （Apri. 2008 to March 2009） i. Lahore, Paki.tan. A total of thi.ty ni.e samples were collected on 47 mm Zefi.or Teflon fi.ter membranes and each was analysed to characteri.e for the elements： Sb, As, Be, Cd, Cr, Co, Pb, Mn, Hg usi.g i.P-MS i. water extract and total aci. di.estate.
