Abstract
The increasing global use of pesticides in crop pest control has raised concerns about toxic interactions. This study investigates the interaction between glyphosate and cypermethrin formulations concerning cell death and genotoxicity. Three models were applied to assess whether the combined effects were additive, antagonistic, or synergistic: "Linear Interaction Effect", "Combination Subthresholding," and "Cooperative Effect". Key indicators, such as apoptotic nuclei, caspase 3/7 activity, early and late apoptosis, micronuclei frequency, and mitotic abnormalities, were evaluated. Results showed synergistic effects on early and late apoptosis, as indicated by the "Linear Interaction Effect" model, while morphological apoptosis markers and micronuclei frequency displayed additive effects. Caspase 3/7 activity induction was synergistic, though no interaction was observed in the combination effect. These findings suggest that agrochemical mixtures cause more severe toxic effects than individual chemicals, emphasizing the need for mechanistic studies on common environmental contaminant mixtures.
期刊介绍:
Environmental Toxicology and Pharmacology publishes the results of studies concerning toxic and pharmacological effects of (human and veterinary) drugs and of environmental contaminants in animals and man.
Areas of special interest are: molecular mechanisms of toxicity, biotransformation and toxicokinetics (including toxicokinetic modelling), molecular, biochemical and physiological mechanisms explaining differences in sensitivity between species and individuals, the characterisation of pathophysiological models and mechanisms involved in the development of effects and the identification of biological markers that can be used to study exposure and effects in man and animals.
In addition to full length papers, short communications, full-length reviews and mini-reviews, Environmental Toxicology and Pharmacology will publish in depth assessments of special problem areas. The latter publications may exceed the length of a full length paper three to fourfold. A basic requirement is that the assessments are made under the auspices of international groups of leading experts in the fields concerned. The information examined may either consist of data that were already published, or of new data that were obtained within the framework of collaborative research programmes. Provision is also made for the acceptance of minireviews on (classes of) compounds, toxicities or mechanisms, debating recent advances in rapidly developing fields that fall within the scope of the journal.
