Comparative evaluation of solid-phase extraction and in-tube liquid-liquid extraction for determination of triazole pesticides in water samples
TLDR
In this article, the authors compared two extraction methods (in-tube liquid-liquid extraction and solid-phase extraction) in terms of precision, recovery percentage and time, and found that solid phase extraction performed better than liquid liquid extraction.Abstract:

Transformation pathways and toxicity assessments of two triazole pesticides elimination by gamma irradiation in aqueous solution
TL;DR: In this paper, the degradation of two triazole pesticides (Myclobutanil and Penconazole) in aqueous solution was studied by gamma irradiation, and the results showed that the degradation process of the target molecules was of pseudo-first order and the elimination reached at least 90% at an absorbed dose of 575 Â Â and 460 Ã Â for Mycloburanil, respectively.
