Evaluation of Acephate Metabolites Generated by Zebrafish (Danio rerio) Using LC–HRMS and Metabolomics Approach

Journal of Applied Toxicology, EarlyView.
ABSTRACT Acephate is an organophosphate insecticide widely used. This pesticide can be metabolized into methamidophos, a molecule highly toxic. Both have demonstrated the ability to promote serious toxic effects on nontarget organisms and have been identified in surface waters around the world. Therefore, it is important to understand their behavior in

LIMIT OF DETECTION (LOD) AND LIMIT OF QUANTITATION (LOQ) OF DR 1900 SPECTROPHOTOMETER FOR DYES ANALYSIS

Berkala Penelitian Teknologi Kulit, Sepatu, dan Produk Kulit
Dyes is not easily degraded in the environment. It can be causing environmental pollution. The concentration of these dyes must be monitored when using it in a process. The most common method to measuring dye’s concentration is spectrometry, such as using dr 1900 spectrophotometer.

Evaluating the Endocrine‐Disrupting and Oxidative Stress Potential of a 50‐Component Human‐Relevant Complex Chemical Mixture Using In Vitro Tests

Journal of Applied Toxicology, EarlyView.
ABSTRACT Humans are chronically exposed to mixtures of environmental contaminants. Exposure to endocrine‐disrupting chemicals (EDCs) contributes to increased health impairment observed globally. This study aimed to evaluate the endocrine‐disruptive and oxidative stress potential of a human‐relevant, complex chemical mixture in vitro.

Concurrent Calcium and Magnesium Determination by Ion Chromatography: An Approach to Avoid Interferences That Compromise Analysis. [PDF]

Biomed Chromatogr
ABSTRACT To evaluate phosphate‐binding by calcium succinate and combinations of calcium and magnesium salts, ion chromatography (IC) methods were developed and validated for the determination of calcium and magnesium across the pH range in the human gastrointestinal tract (pH 1.2–6.8). Separation was achieved on a Dionex IC system using a Dionex IonPac
