Resistance to triazoles in Aspergillus fumigatus has been reported in azole-naive patients in Europe, Asia, Australia and North America. This resistance has been linked to fungicide-driven mutations in the cyp51A gene and its promoter region. We investigated the presence of environmental azole-resistant A. fumigatus strains related to the use of azole fungicides in Colombia. Soil samples were c...

Electrochemical oxidation using a boron-doped diamond anode (EO-BDD) was tested to remove emerging contaminants commonly present in wastewater treatment plant effluents (WWTPe). The main objective of the work regeneration this water for its possible reuse high-quality demanding uses. In first part work, we investigated potential technique removing group neonicotinoid pesticides (thiamethoxam (T...

The residues of deltamethrin, penconazole, kresoxim-methyl, cyproconazole, epoxiconazole and azoxystrobin were determined in husk rice, brown bran, fifty samples each matrix, obtained from industrial rice facilities, to estimate the distribution contamination levels during processing; exposure these pesticides through intake. analytical methodologies required validated. QuEChERS extraction gas ...

BACKGROUND In South Africa there is little data on environmental pollution of rural water sources by agrochemicals. METHODS This study investigated pesticide contamination of ground and surface water in three intensive agricultural areas in the Western Cape: the Hex River Valley, Grabouw and Piketberg. Monitoring for endosulfan and chlorpyrifos at low levels was conducted as well as screening...

Pruned vine-shoots used as wine additives have proven to be a useful tool for improving and differentiating wines. This is because they accumulate substances from the plant itself, which later, result of toasting process, express their greatest oenological potential. However, vine being one crops subject most phytosanitary treatments, including fungicides in particular, it can assumed that resi...

In order to optimize the application of nutritive solutions and phytosanitary treatments with direct influence on quality cut roses from hydroponic culture (soilless culture), it is necessary study biochemical composition different organs plant (leaves). By FT-IR spectroscopy using standard KBr pellet technique; was possible differentiate between 10 Rosa cultivars based chemical leaves also ide...
