Abstract

Goal: to detect both known and unknown pesticides and their transformation products in the environment The high-resolution accurate mass Thermo Scientific QExactive instrument in combination with the UltiMate 3000 UHPLC and Thermo Accucore aQ separation column, has for us proven a very robust setup for the screening of 850 pesticides and degradation products with unknown and known retention times in soil, water and food of plant origin. The screening method, with quantification, is used routinely for our research projects. Our screening method covers almost all the pesticides used in Norway. Exceptions are e.g. glyphosate, acidic herbicides and a few biopesticides and growth regulators which require adapted analysis methods, and some pesticides that can only be measured by GC-MS.

Abstract

The role of soil in current climate models is reviewed and discussed, with a focus on developments over the last two decades. Soil modeling may be divided into three major parts: simulation of soil hydrological dynamics, soil biogeochemistry and the soil thermal environment. Each of these three major parts is summarized with a brief description of current best practice and developments. Specific issues and modifications relevant to four extreme environments are highlighted: drylands, tropical moist and wet forests, cold regions, and peatlands and wetlands. Finally, current advances in the areas of hyperresolution and coupled model environments are discussed, which we see as the two leading edges of current soil model development.
