Volatilization of pesticides from the bare soil surface: evaluation of the humidity effect.
Volatilization of pesticides from soils under dry conditions (water content below the permanent wilting point) can be significantly influenced by sorption to hydrated mineral surfaces. This sorption process strongly depends on the water activity, expressed as equilibrium relative humidity in the pore space of the soil, and on the available surface area of the hydrated minerals. In this study, t...
متن کاملSpatial Soil Modeling of Organochlorine Pesticides, Their Pools and Volatilization Fluxes
The goal of this study was to use the modeling tools for prediction of environmental concentrations and pools of pesticides (HCB and DDT) in soil. The characterization and quantification of secondary background sources of HCB, were computed using fugacity based deterministic model. Areas with a high potential for deposition and volatilization of HCB were identified. Results of modeling were map...
متن کاملVolatilization of Mercury by Bacteria.
Volatilization of mercury has been observed from various biological media (tissue homogenates, infusion broth, plasma, urine) containing mercuric chloride. That micro-organisms were responsible was indicated by the finding that the rates of volatilization were highly variable, that a latent period often preceded volatilization, that toluene inhibited the process, and that the capacity to volati...
متن کاملVolatilization Behavior of Heavy Metal Chlorides from
Molten fly ashes generated from melting treatment of municipal solid waste and automobile shredder residues are characterized as hazardous waste due to the high content of heavy metals such as Zn, Pb and Cu. In addition, the heavy metal resources could be depleted in the near future and thus, the research towards conservation of metal resources is required. In the present work, volatilization b...
متن کاملEffect of Äo2 on Sic Volatilization Rate
Introduction: Our previous work on the volatilization rate of SiC in reducing gases [1, 2] was restricted to IW-2.8 and IW-6, oxygen fugacities (ÄO2Õs) 2.8 and 6 log units below the iron-wustite (IW) buffer. These data allowed us to estimate lifetimes of interstellar SiC grains (several months at 1200¡C) in a gas of solar composition (~IW-6). There is, however, evidence that ÄO2Õs for many comp...
