Determinação do glifosato e ácido aminometilfosfônico (AMPA) em solo via HPLC-MS/MS

Abstract: O herbicida glifosato foi introduzido no mercado em 1970 e hoje é amplamente utilizado em todo o mundo. Após a aplicação, esse herbicida pode ser metabolizado pelas plantas ou submetido à água ou ao solo e pode ser degradado por microrganismos presentes no solo. Fatores, como pH, granulometria e matéria orgânica contribuem para sua adsorção no solo. Dependendo do teor de matéria orgânica do solo, este herbicida é degradado em seu principal metabólito, o ácido aminmetilfosfônico (AMPA). Atualmente, devido à com… Show more

“…Scotopic: vision under dim light based on rods, Photopic: vision under well-lit light based on s/m cones. Figure 2b adapted from [68]. An architectural lighting system with programmable control of light intensity (2,500 lux) applied for an extended period resulted in staff complaining about visual discomfort [65].…”

“…Hence, all previous results are skewed with respect to their effect size and need to be re-scaled. Researchers from chronobiology, physics and engineering aimed at a new light-measurement strategy taking into account the complex photoreceptive inputs to these non-image forming functions by redefining spectral luminous efficacy functions according to all five photoreceptors, so-called α-opics [67,68]. Large numbers of already published studies have been made comparable by rescaling light intensities to α-opic daylight equivalent illuminances and indeed the biologically-weighted values showed better correlations with expected effects using, for example, melanopic-weighted rather than photopic light intensities for melatonin suppression (Figure 2b, [68]).…”
