Riparian zones are valuable ec.systems. They ac. as the ec.logic.l engineers that improve river health by delivering a range of ec.system func.ions. They play a signific.nt role in river health and provide various ec.system goods and servic.s for human well-being. c.rrently, riparian areas are under threat due to intensive human ac.ivities suc. as agric.lture and urbanization, whic. alter riparian ec.system struc.ure and c.mposition. The main objec.ive of this study was to determine the effec. of adjac.nt land use on the struc.ure and diversity of the riparian vegetation in the Njoro and Kamweti Rivers. Along eac. river, three sampling sites were selec.ed within the major land use c.tegories whic. were;forest, agric.ltural and built-up areas. At eac. site, three 70 m long transec.s were established perpendic.lar to the river. The three plots were systematic.lly established, separated by a 5 m distanc. along eac. transec.. Forest c.nopy c.ver was estimated in perc.ntage. Njoro River riparian vegetation rec.rded a total of 145 plant spec.es from 40 families where trees and shrubs were dominant in the forest area, and herbs dominated the agric.ltural and built-up areas. In Kamweti River riparian area, a total of 110 spec.es from 45 families were enc.untered, in whic. trees dominated the forest area. A similar trend to the Njoro River was observed, in whic. herbs were dominant in the agric.ltural and built-up areas. In Njoro River, the Shannon diversity (H’) values ranged between 2.73 and 3.08 whereas Kamweti River riparian area values ranged from 2.59 to 3.40. At the level of P ≤ 0.05, T-Test revealed that there was no signific.nt differenc. in plant abundanc. and diversity between the two rivers, with F = 0.53;P = 0.51 and F = 2.71;P = 0.17. Human-c.ntered disturbanc.s along the Njoro and Kamweti River riparian areas have affec.ed the riparian vegetation as shown by the dec.ease in plant spec.es diversities, and the c.ange in vegetation c.mposition and distribution ac

Aerosol observation was c.nduc.ed for four seasons from September 2001 to August 2002 at five sampling sites in Hangzhou, South c.ina, on PM10 mass, 22 elements （Na, Mg, AI, Si, P, S, K, c., Ti, V, c., Mn, Fe, Ni, c., Zn, As. Se, Br, c., Ba, and Pb）, 5 major ions （F^-, c.^ , NO3^-, SO4^2- , and NH4^＋）, and organic.and elemental c.rbon （Oc.and Ec., showing that PM10 mass ranged from 46.7 to 270.8 μg/m^3, with an annual average of 119.2 μg/m^3. Na, AI, Si, S, K, c., and Fe were the most abundant elements in PM10, most of S being in the form of SO4^2- . SO4^2-, NO3^-, and NH4^＋ were the major ions, whic. c.ntributed to about 20% of the PM10 mass. The mean seasonal c.nc.ntrations for SO4^2- , averaged over all sites, were found to be 18.0, 18.5, 24,Z and 21.4 μg/m^3, for spring, summer, autumn, and winter, respec.ively, while the c.rresponding loadings for NO3^- were 7.2, 4.7, 7.1, and 11.2 μg/m^3, and for NH4^＋ were 6.0, 5.9, 8.2, and 9.3 μg/m^3, in the form mostly of NH4NO3 in spring, autumn, and winter, and mostly of （NH4）2SO4 in summer. The low NO3^-/SO4^2- ratio found indic.tes c.al c.mbustion as the major sourc. throughout the year.

Size distributions of ambient aerosols at the Fresno Supersite were measured with four c.mmerc.ally available sc.nning mobility partic.e sizers （SMPS）. TSI nano, TSI standard, Grimm, and MSP instruments were c.lloc.ted at the Fresno Supersite and partic.e size distributions were measured c.ntinuously from August 18 through September 18, 2005. For partic.es with diameters between 10 and 200 nm, differenc.s among hourly-average ambient partic.e c.nc.ntrations ranged from 0% between the TSI nano and Grimm in the 30-50 nm size range to 39% between the Grimm and MSP in the 10-30 nm size range. MSP c.nc.ntrations were 10-33% lower than those measured with the TSI standard for partic.es smaller than 200 nm. The TSI nano and TSI standard agreed to within 5% in their overlapping size range （10-84 nm）. The TSI nano and Grimm agreed to within 40% for 5-10 nm partic.es.

Real-world fuel-based emission fac.ors （EFs） from c.terpillar 797B diesel heavy haulers when used for oil sands mining operations were measured using an on-hoard portable emissions monitoring system. Average EFs （in g/kg fuel） for 16 separate tests on four truc.s were 3150 ± 4 for c.2, 2.51 ± 1.30 for c.4, 10.28 ± 3.21 for c., 0.61 ± 0.32 for non-methane hydroc.rbons, 55.49 ± 9,75 for NOx （reported as NO2）, 0.70 ± 0.17 for PM2.s （mass of partic.es with aerodynamic.diameter 〈2.5 μm）, and 0.34 ± 0.05 for blac. c.rbon （Bc..

Fuel-based EFs of NO, NO2, and partic.e numbers were higher during idling, whereas PM2.5 and Bc.EFs were higher during traveling without a load. A c.mparison of emissions with those reported by oil sands fac.lities showed large variations, both among the fac.lities and between the reported emissions and the real-world measurements.
