A simple determination method of diphenyl (DP) and o-phenylphenol (OPP) in agricultural products by GC/MS was examined. DP and OPP were extracted with ethyl acetate in the presence of anh. sodium sulfate. After addition of n-butanol, the extract solution was concentrated. Clean-up was achieved by shaking with graphitized bulk carbon (Supelclean ENVI-Carb). Addition of polyethylene glycol sharpe...

A multiresidue analysis of pesticides in tea using supercritical fluid extraction (SFE) and GC-MS was developed. The preprocessing using SFE shortened the total analysis time. The SFE extract contained less matrices than the extract obtained with organic solvents. However, these matrices disturbed instrumental analysis. So, the extract was cleaned up with ENVI™-Carb/NH2 and InertSep™ SI cartrid...

High concentrations of ozone (O3) is a major air problem in urban areas, which creates serious threat to human health. Urban street canyon morphology plays key role pollutant dispersion and photochemical reaction rate. In this study, one-year observation at three height levels was performed investigate the O3 distribution vertically Shenyang. Then, field investigation ENVI-met modelling were co...

Vegetation configuration in residential districts improves human comfort by effectively moderating the thermal environment. Herein, reliability of ENVI-met is verified comparing field measured with simulated data, including air temperature and relative humidity. The cooling effect trees gradually increased increasing tree coverage. Under same coverage, a crown diameter (TCD) 3 m have strongest ...

In the city of Erzurum, located in a cold climate region, it is important for pedestrian walkways and parks to be usable all year round. Haydar Aliyev Street, on city's new development axis, serves as both route park. Meteorological data was collected hourly throughout 2021 using Vantage Pro 2 Plus device installed at height 1.5 m study area. The scenarios were analyzed ENVI-met BIO+ Science So...
