THMs in disinfection by products are especially important because of their potential carcinogenity. In this work two different liquid-phase microextraction methods namely US EPA 551 microextraction method and German DIN 38407 standard method were compared for the determination of trihalomethanes (THMs) including chloroform (CHCl3), bromodichloromethane (CHBrCl2), dibromochloromethane (CHBr2Cl) and bromoform (CHBr3) in water samples was developed, with analysis by gas chromatographyelectron capture detection (GC-EC...

In this study, global warming’s effects on soil temperature of Turkey was evaluated by analysis of the spatial and temporal variations of the soil temperature data with the help of 3.5D Geographical Information System (GIS) Models. Soil temperature data in 5 cm, 10 cm, 20 cm, 50 cm and 100 cm depths in 74 city centers since 1975 were used. These data were compared with 34 years mean temperature of each city and deviations were shown by using GIS on the map. It is determined that soil temperature values in Turkey h...
