Sample preparation techniques for suspect and non-target screening of emerging contaminants [PDF]

Chemosphere, 2022
The progress in sensitivity and resolution in mass spectrometers in recent years provides the possibility to detect a broad range of organic compounds in a single procedure. For this reason, suspect and non-target screening techniques are gaining attention since they enable the detection of hundreds of known and unknown emerging contaminants in various

Exposomic Biomonitoring of Polyphenols by Non-Targeted Analysis and Suspect Screening

Analytical Chemistry, 2023
Polyphenols, prevalent in plants and fungi, are investigated intensively in nutritional and clinical settings because of their beneficial bioactive properties. Due to their complexity, analysis with untargeted approaches is favorable, which typically use high-resolution mass spectrometry (HRMS) rather than low-resolution mass spectrometry (LRMS).

Non-target screening of emerging contaminants in landfills: A review

Current Opinion in Environmental Science & Health, 2023
Leachate from landfills is considered an important point source of contamination, which poses significant threat to the receiving ecosystems and their resources. Therefore, it is necessary to monitor the occurrence of contaminants, and develop effective treatment processes, and to achieve this, target, suspect and non-target screening must be employed.

Bladder cancer biomarker screening based on non-targeted urine metabolomics [PDF]

International Urology and Nephrology, 2021
Bladder cancer is one of the most common malignancies of the urinary system, and its screening relies heavily on invasive cystoscopy, which increases the risk of urethral injury and infection. This study aims to use non-targeted metabolomics methods to screen for metabolites that are significantly different between the urine of bladder cancer patients ...

Hyphenated TLC as a Tool in the Effect-Directed Discovery of Bioactive Natural Products

Applied Sciences, 2020
Complex samples such as botanical extracts contain hundreds of compounds. Since we can only identify compounds that are stable, extractable, separable and detectable from complex botanical extracts, minimal sample treatment and different detection ...

NORMAN guidance on suspect and non-target screening in environmental monitoring [PDF]

Environmental Sciences Europe, 2023
AbstractIncreasing production and use of chemicals and awareness of their impact on ecosystems and humans has led to large interest for broadening the knowledge on the chemical status of the environment and human health by suspect and non-target screening (NTS).

Suspect and non-target screening of acutely toxic Prymnesium parvum

Science of The Total Environment, 2020
Harmful algal blooms (HABs) are increasing in frequency, magnitude, and duration around the world. Prymnesium parvum is a HAB species known to cause massive fish kills, but the toxin(s) it produces contributing to this acute toxicity to fish have not been confirmed.
