Temperature and soil moisture change microbial allocation of pesticide‐derived carbon

European Journal of Soil Science, Volume 74, Issue 5, September–October 2023., 2023
Changing environmental conditions alter the MCPA degradation dynamics and the allocation of pesticide‐derived carbon to anabolic or catabolic metabolism. Abstract Temperature and soil moisture are known to control pesticide mineralization. Half‐life times (DT50$$ {DT}_{50} $$) derived from pesticide mineralization curves generally indicate longer ...

LUCAS Soil Biodiversity and LUCAS Soil Pesticides, new tools for research and policy development

European Journal of Soil Science, Volume 73, Issue 5, September–October 2022., 2022
Abstract The European Green Deal puts a healthy environment at the core of policy‐making initiatives in the European Union (EU). Soil, due to its nature, is a central actor to be considered when developing and implementing actions in many areas, from biodiversity and agriculture to climate and pollution. New means for monitoring the impact of decisions

Rapid Screening of 352 Pesticide Residues in Chrysanthemum Flower by Gas Chromatography Coupled to Quadrupole‐Orbitrap Mass Spectrometry with Sin‐QuEChERS Nanocolumn Extraction

Journal of Analytical Methods in Chemistry, Volume 2022, Issue 1, 2022., 2022
To analyze pesticide residues, GC coupled with quadrupole‐Orbitrap MS (GC‐Orbitrap‐MS) has become a powerful tool because of its unique characteristics of accurate mass full‐spectrum acquisition, high resolution, fast acquisition rates, and overcoming matrix interference. This paper presents an efficiency evaluation of GC‐Orbitrap‐MS for identification

Residue Kinetics of Ethofumesate in Texturally Diverse Soils of Sugar Beet Crop under Field Conditions

Journal of Chemistry, Volume 2021, Issue 1, 2021., 2021
Indiscriminate use of pesticides and growing awareness of environmental and health problems had led to monitoring their residues in soil and crops. Ethofumesate is one of the widely used herbicides for controlling weeds in sugar beet. Dissipation kinetics and terminal residues of ethofumesate were investigated in two diverse soils under subtropical ...
