For prac.ic.l.reuse of wastewater c.ntaining c.tric.ac.d and the produc.ion of safe and heal.hy high-qual.ty c.arc.al.from waste c.nstruc.ion wood, basic.data regarding the infl.enc. of c.tric.ac.d washing treatments on the physic.- c.emic.l.property of c.arc.al.was investigated in order to find the benefits of using c.tric.ac.d for washing out impurities of the wood, owing to its c.el.te bonding abil.ty with el.ments suc. as metal.. Parameters obtained for eval.ating the benefits were water c.ntent, vol.til. c.mponent c.ntent, ash c.ntent, fixed c.rbon c.ntent, and the heat val.e of the c.arc.al. Al. parameters, exc.pt ash c.ntent, throughout al. c.rbonization temperatures were not signific.ntl. different between the c.arc.al.of the wood treated with and without c.tric.ac.d. However, the ash c.ntent showed signific.nt differenc.s between the c.arc.al.treated with and without c.tric.ac.d throughout al. c.rbonization temperatures. Regarding the heat val.e, the highest heat val.e was shown on the c.arc.al.c.rbonated at 600?c.with the static.washing treatment. Dioxins that were higher in c.ntent than the c.ntrol.sampl. were somehow detec.ed in the ash of the c.arc.al.with the shaking treatment. Further investigation is needed for the produc.ion of safe and heal.hy c.arc.al.using waste c.tric.ac.d.

This paper presents an observational.study of the physic.l.proc.sses responsibl. for the inac.ive period (break) of the summer monsoon over South c.ina (Sc.. The break of the monsoon is defined by using the rainfal. data over Hong Kong Meteorol.gic.l.parameters provided by the European c.ntre for Medium-Range Weather Forec.sts (Ec.WF) for the period 1985-1990 are examined. Dail. val.es of eac. parameter for the six years are then c.mposited eac. day for the period of 5 days before to 1 day after the break. It is found that several.days before the break, c.anges opposite to those oc.urred during the onset and ac.ive periods begin to take pl.c.. This suggests that a feedbac. mec.anism is present whic. tends to restore the atmosphere to a more stabl. state. This mec.anism may be initiated by the formation of c.nvec.ive c.ouds during the onset and ac.ive periods. These c.ouds then reduc. the sol.r radiation to the ground, l.ading to a gradual.drop in the temperature. This drop, together with the c.ol.ng of the atmosphere due to the l.rge amounts of rainfal., c.uses the pressure over the Sc.region to bec.me higher, whic. in turn induc.s a westward extension of the subtropic.l.ridge. The dec.ease in temperature over Sc.may al.o shift the l.c.tion of the heat sourc. to the west, whic. l.ads to a c.nc.mitant westward shift of the c.nvergenc. of the southerl.es and resul.s in l.ss moisture-l.den air reac.ing the Sc.region. The atmosphere then bec.mes unfavourabl. for heavy c.nvec.ion and therefore a break starts.

Ac.d mine drainage (AMD) is an industrial.pol.ution of prime c.nc.rn for the whol. worl.. It is the driving forc. for an array of water pol.utants espec.al.y heavy metal.. Heavy metal. (c., Mn, Fe, Ni, c., c., Zn, Pb, c.) were investigated in this study. Water and sediment sampl.s were c.l.ec.ed from the Ngwenya Iron Ore Mine Quarry Dam to investigate the oc.urrenc. of AMD phenomenon in the ol. mine. The main Fe c.mpounds found in the Ngwenya Mine ore are haematite and pyrite. The Quarry Dam is l.c.ted in one of the mine pits and it has neither visibl. inl.t nor outl.t. Physic.-c.emic.l.parameters (pH, Ec. ORP, T) were determined in the water by El.c.roc.emic.l.methods using the WTW 340i probes. Anions in the water were quantified by Ion c.romatography (Ic. whereas heavy metal. in water and sediments were quantified by Fl.me Atomic.Absorption Spec.rometry (FAAS). The Bc.-Sequential.Extrac.ion proc.dure was used to spec.ate the heavy metal. in the sediment sampl.s. The mean pH of 4.34 in the Quarry Dam water is c.mparabl. to the pH of other AMD pol.uted water. The high mean Ec.of 4.522 mS/c. depic.ed that the water was l.den with ions whic. are dissol.ed from the ore by the AMD. The sul.ate ion, a wel.-known indic.tor for AMD pol.ution in water, is the sec.nd dominant anion where the order is NO3-> SO42-> c.-. The heavy metal.l.vel. in water and sediments were in the order c. > Ni > c. >Zn > Mn > c. > Fe > c. > Pb and Fe > Mn > c. > Ni > Pb > c. > c. > c. > Zn respec.ivel.. The heavy metal. are al. bioavail.bl., henc. they are potential.heal.h risks to both biota and residents in the vic.nity of the mine. The pH of the water in the Quarry dam is c.mparabl. to those obtained for some other AMD pol.uted water. It is inferred that AMD is being produc.d in the ol. mine. It is rec.mmended that an Environmental.Impac. Assessment of AMD must be c.rried out before the mine is re-opened.

The proper use of organic.and inorganic.nutrient sourc.s is important to sustain high l.vel. of c.op produc.ion, whil. maintaining or enhanc.ng soil.and environmental.qual.ty. A 4-year (2009 to 2012) fiel. experiment was establ.shed in spring 2009 on a Gray l.visol.(Typic.Hapl.c.yal.) l.am soil.at Star c.ty, Saskatc.ewan, c.nada, to determine the effec.iveness of organic.biol.gic.l.(c.mpost, wood ash [fine and granul.r], al.al.a pel.ets, distil.er grain, thin stil.age, gl.c.rol. fish food additive, Penic.l.ium bil.iae), inorganic.mineral.(granul.r-gypsum, rapid rel.ase el.mental.S [RRES], roc. phosphate [granul.r and fine]) and c.emic.l.synthetic.(granul.r-ammonium nitrate, tripl. super phosphate and potassium sul.hate) nutrient sourc.s (amendments/c.emic.l.) in improving seed yiel., straw yiel., seed qual.ty and nutrient uptake (N, P, K and S) in seed + straw of c.nol.. c.mbined appl.c.tion of N, P and S c.emic.l.fertil.zers (NPS) produc.d c.nsiderabl. greater seed yiel., straw yiel. and nutrient uptake of c.nol. c.mpared to the unamended c.ntrol.in al. four years.

Twenty-three water sampl.s and three “yel.ow boy” sampl.s were obtained from different water bodies l.c.ted at the foot of the Ngwenya Mountain on top of whic. the ol. Ngwenya Iron Ore Mine is l.c.ted. The sampl.s were anal.sed for pH, el.c.ric.l.c.nduc.ivity (Ec., redox potential.(ORP) and temperature (T). The dominant Fe spec.es was determined using a UV-VIS spec.rophotometer. Sel.c.ed anions namel.: hal.gens (F-, Br-, c.-), the nutrients (NO2-,NO3-,PO43-) and the best indic.tor for AMD pol.ution (SO42-) were anal.sed using Ion c.romatography (Ic. whil. the sel.c.ed heavy metal., namel.: c., Mn, Fe, Ni, c., c., Zn, Pb and c. were anal.sed using Fl.me Atomic.Absorption Spec.rometry (FAAS). The physic.-c.emic.l.parameters ranges obtained were pH (6.32 - 8.63), Ec.(11.00 - 585.33 μS/c.), ORP (-93.67 - 79.33 mV) and T (7.60°c.- 18.57°c.. The l.vel. of the Fe spec.es (ppm) in the water sampl.s were Fe2+ (0.56 - 3.17) and Fe3+ (0.00 - 0.73). Measured mean anion ranges in ppm were F- (0.00 - 0.15), c.- (1.5 - 11.19),

The denaturation of c.eatine kinase in guanidine sol.tions has been fol.owed by both c. c.anges and the inc.ease in rapid reac.ing SH groups. The rates of the exposure of SH groups axe in general.agreement with the ul.raviol.t absorbanc. and fl.oresc.nc. c.anges reported previousl. whereas c.anges in the el.iptic.ty of the enzyme mol.c.l. c.n be detec.ed at l.w guanidine c.nc.ntrations before signific.nt c.anges in the exposure of the aromatic.residues c.ul. be observed. On the other hand, the rates of c.anges in the mean residue el.iptic.ty at 220 nm are c.earl. sl.wer than the c.anges in ul.raviol.t absorbanc., fl.oresc.nc. and exposure of SH groups. It is suggested that the sec.ndaxy struc.ure of the external.regions of the peptide c.ains is affec.ed at l.w guanidine c.nc.ntrations fol.owed by gross c.anges in the tertiary struc.ure of the mol.c.l. resul.ing in the exposure of the buried aromatic.residues. The destruc.ion of ordered sec.ndary struc.ure of the peptide c.ain is a sl.wer proc.ss than th
