With the growing global concern on pesticide management, the relationship between its environmental recalcitrance, food security and human health has never been more relevant. Pesticides residues are known to cause significant environmental contamination. Here, we present a case study on long-term no-tillage farming systems in Brazil, where Glyphosate (GLY) has been applied for more than 35 years. GLY and its main breakdown product, aminomethylphosphonic acid (AMPA) were determined in topsoil (0–10 cm) samples from no-tillage fields and nearby subtropical secondary forests by high-performance liquid chromatography coupled with a fluorescence detector. In addition, the presence of carbamates, organochlorines, organophosphates and triazines were also screened for. GLY and AMPA were present in all soil samples, reaching values higher than those described for soils so far in the literature. A significant decrease for AMPA was observed only between the secondary forest and the farm’s middle slope for site B. GLY and AMPA were observed respectively at peak concentrations of 66.38 and 26.03 mg/kg soil. GLY was strongly associated with forest soil properties, while AMPA associated more with no-tillage soil properties. Soil texture was a significant factor contributing to discrimination of the results as clay and sand contents affect GLY and AMPA retention in soils. This was the first study to report DDT and metabolites in consolidated no-tillage soils in Brazil (a pesticide fully banned since 2009). Based on human risk assessment conducted herein and the potential risk of GLY to local soil communities, this study offers a baseline for future studies on potential adverse effects on soil biota, and mechanistic studies.

ABSTRACT: The success of the assisted reproductive techniques (ART) in both humans and domestic animals depends of the semen quality. Since there is no test that alone can predict sperm fertility, as more sperm parameters are analyzed during evaluation, more acurated will the result. The evaluation of the DNA integrity during the exam of bovine fresh and frozen sperm is of fundamental importance to avoid embryonic losses. The terminal deoxynucleotidyl transferase mediated dUTP nick end labeling assay (TUNEL) has been an efficient method to detect sperm DNA fragmentation, avoiding problems of embryonic development and decrease of the animal reproductive efficiency. This work presents and describes with the TUNEL technique (principles, advantages and detailed protocol), indicating this tool to evaluate the bovine sperm DNA. |
