In current study, the effects of Iranian rice cooking method (Kateh) on residue levels of 41 pesticides were investigated. The pesticides were selected according to Iranian National Standards Organization (INSO) regulations and covered 18 permitted and 23 banned pesticides belonging to different chemical classes such as organophosphate, triazole, and carbamate. A 250 g portion of rice sample wa...

For the ammonia generated in Korea, contribution rate of livestock manure is high, and a large amount (NH3) emitted into atmosphere during soil application process. Volatilization NH3 affected by characteristics as well characteristics, but current inventory does not sufficiently reflect this. This study was conducted to confirm change from liquid fertilizer (LF) due pH evaluate impacts biochar...

As part of study the volatilization ruthenium behaviour in a boiling nitric solution, this paper presents results experiments dealing with influence different parameters (Ru and HNO3 concentrations, temperature, water addition) effect in-situ inhibitors to mitigate potential releases. The amount Ru volatilized from solution heated at 130 °C is about 2% initial inventory. addition low allowed pr...

Mold powders are fluxing agents used as raw materials in the steel industry, which play very important role in processing stability and final surface quality of a product. Surface quality depends particularly on the viscosity and the heat transfer of infiltrated mold flux between the mold wall and the solidified steel shell. Heat flux across the interfacial gap depends on thermal properties of ...

Nitrogen-15 ( N)-labeled biogas slurry (digested anaerobic organic residues (DAOR)) and chemical 15 fertilizer (CF) were applied to soil with low fertility cropped with rice. The N dilution method was used to 15 estimate the N uptake and recovery; potted soil was labeled with 1.0 atom % excess [ N] ammonium chloride 15 NH Cl. Certain select soil characteristics were also measured in soil amende...

The goal of this project was to measure directly the volatilization of gas phase polychlorinated biphenyls (PCBs) from stabilized dredged material (SDM) in a • laboratory scale flux chamber. This study complements earlier field observations (Phase I) to estimate PCB fluxes from SDM being applied to a landfill (Korfiatis et. al., 2003, Miskewitz et al, 2004). Phase I included measurements of the...

A sprinkler irrigation system was tested to assess its efficacy for volatilizing organic chemicals in pumped groundwater. In field tests involving the analysis of more than 250 samples collected from beneath a spray irrigation system, removal rates of ethylene dibromide (EDB), 1,1,2-trichloroethylene (TCE), 1,1,1-trichloroethane (TCA), and carbon tetrachloride (CT) in samplers placed 0.5 m abov...

Different organic materials possessing antimicrobial properties have the ability to retard nitrification. Nitrification retarders could be successfully used to improve fertilizer efficiency if the retarders do not increase ammonia volatilization as well. The main objective of this study was to find whether any locally available organic materials namely cow dung, seed crush of Syzygium cumini, L...
