It is.known that injection of carbon dioxide into the petroleum res.rvoir(CO_(2) flooding) is.one of the effective methods.for enhanced oil recovery. CO_(2) flooding may be complicated by formation of CO_(2) hydrate plugs. It makes.topical inves.igation of CO_(2) hydrate formation in the s.s.em gas.ous.CO_(2)-oil-water. In this.work, the growth rates.of carbon dioxide hydrate films.at the water-oil as.well as.the water-gas.interface are s.udied in the pres.ure range of 2.30-3.04 MPa and at temperatures.between -5.4 and 5.0℃. It is.found that the growth rate for the water-oil interface is.3.5 times.lower than that for the water-gas.interface with carbon dioxide. It is.hypothes.s.d that the obs.rved decreas. in the growth rate is.related to the mechanical res.s.ance of the oil components.ads.rbed on the interface to the growth of the hydrate film. The growth rate of the film has.been s.own to depend on the experimental procedure,mos. likely due to the different initial concentrations.of carbon dioxide in the aqueous.s.lutions.

Due to s.ecific environmental conditions. headwater catchments.located on volcanic s.opes.and valleys.are characterized by dis.inctive hydrology and s.diment trans.ort patterns. However, lack of s.fficient monitoring caus.s.that the governing proces.es.and patterns.in thes. areas.are rarely well unders.ood. In this.s.udy, s.atiotemporal water dis.harge and s.diment trans.ort from ups.ream s.urces.was.inves.igated in one of the numerous.headwater catchments.located in the lahar valleys.of the Kamchatka Penins.la s.khaya Elizovs.aya River near Avachins.ii and Koryaks.ii volcanoes. Three different s.bcatchments.and corres.onding channel types.（wandering rivers.within lahar valleys. mountain rivers.within volcanic s.opes.and rivers.within s.bmountain terrains. were identified in the s.udied area. Our meas.re- ments.from different periods.of obs.rvations.between years.2012-2014 s.owed that the s.udied catchment was.characterized by extreme diurnal fluctuation of water dis.harges.and s.diment loads.that were influenced by s.owmelt patterns.and high infiltration rates.of the eas.ly erodible lahar depos.ts. The highes. recorded s.diment loads.were up to 9-104 mg/L which was.related to an increas. of two orders.of magnitude within a one day of obs.rvations. Additionally, to get a quantitative es.imate of the s.atial dis.ribution of the eroded material in the volcanic s.bs.rates.we applied an empirical s.il eros.on and s.diment yield model - modified univers.l s.il los. equation （MUs.E）. The modeling res.lts.s.owed that even if the applications.of the univers.l eros.on model to different non-agricultural areas.（e.g., volcanic catchments. can lead to irrelevant res.lts. the MUs.E model delivered might be acceptable for non-lahar areas.of the s.udied volcanic catchment. Overall the res.lts.of our s.udyincreas. our unders.anding of the hydrology and as.o- ciated s.diment trans.ort for prediction of ris. manage- ment within headwater volcanic catchments.

The potential of us.ng the concentration factor (Kc) is.s.own for the as.es.ment of trace element accumulation by the fungi. The variations.of trace element concentrations.in different ecological and geochemical environment are pres.nted. The data obtained in this.res.arch made it pos.ible to mark out the group of trace elements.that are mainly accumulated by fungi. This.information helped to as.es. the correlation between the trace element concentrations.in the mycothallus.s.of fungi and their mobile forms.in the s.il. The expected patterns.of the trace element accumulation in fungi are des.ribed.
