Assessment of the Effects of Triticonazole on Soil and Human Health

Abstract

Triticonazole is a fungicide used to control diseases in numerous plants. The commercial product is a racemate containing (R)- and (S)-triticonazole and its residues have been found in vegetables, fruits, and drinking water. This study considered the effects of triticonazole on soil microorganisms and enzymes and human health by taking into account the enantiomeric structure when applicable. An experimental method was applied for assessing the effects of triticonazole on soil microorganisms and enzymes, and the effects of the stereoisomers on soil enzymes and human health were assessed using a computational approach. There were decreases in dehydrogenase and phosphatase activities and an increase in urease activity when barley and wheat seeds treated with various doses of triticonazole were sown in chernozem soil. At least 21 days were necessary for the enzymes to recover the activities. This was consistent with the diminution of the total number of soil microorganisms in the 14 days after sowing. Both stereoisomers were able to bind to human plasma proteins and were potentially inhibitors of human cytochromes, revealing cardiotoxicity and low endocrine disruption potential. As distinct effects, (R)-TTZ caused skin sensitization, carcinogenicity, and respiratory toxicity. There were no significant differences in the interaction energies of the stereoisomers and soil enzymes, but (S)-TTZ exposed higher interaction energies with plasma proteins and human cytochromes.

Protective effects of N-acetyl-l-cysteine against penconazole-triggered hepatorenal toxicity in adult rats

“…The widespread utilisation of fungicides in the agricultural sector and their harmful effects on environmental safety and non-target organisms’ health emphasise the need to investigate their hazardous impact ( 31 ). Penconazole (1-(2-(2,4-dichlorophenyl)-pentyl)-1H-1,2,4-triazole – PEN) is a typical systemic triazole fungicide intensively used in the agricultural sector to control powdery mildew on fruits and vegetables ( 36 ).…”
