  1. 17 Αυγ 2022 · Straight-chain aliphatic aldehydes were repeatedly detected in the breath of patients suffering from lung diseases using a variety of methods, such as mass spectrometry, ion mobility spectrometry, or electro-chemical sensors.

  2. Results of test burns indicate that dramatically increased levels of aldehydes are produced from alcohol-containing fuels (Swarin and Lipari 1983). These higher levels could be well within the range that induces adverse health effects.

  3. 31 Ιουλ 2019 · Here, we discuss the environmental sources of reactive aldehydes and the potential health implications particularly for those with an ALDH2*2 genetic variant. We also suggest when considering the ALDH2*2 genetic variant the safety limits of reactive aldehyde exposure may have to be reevaluated.

  4. Nowadays, this reaction of β-diketone ester, an aldehyde and ammonia or an alkylamine is actively used for the spectrofluorometric determination of a wide range of non-fluorescent substances which contain a primary amino group, as well as for FA detection.

  5. 25 Οκτ 2019 · Aldehydes can be used as diseases biomarkers and food quality indicators. •. Chromatographic determination methods of aldehydes are summarized in this review. •. Effective extraction and derivatization techniques can improve the sensitivity and selectivity. •. The applications and the obtained significant findings are also described. Abstract.

  6. 23 Απρ 2021 · For formaldehyde, the EU Carcinogens and Mutagens Directive of 2019 has recently introduced binding occupational exposure limit (BOEL) values of 0.37 mg m −3 (0.3 ppm) for long-term exposure (8-hour time-weighted average) and of 0.74 mg m −3 (0.6 ppm) for short-term exposure (15 min) for all work sectors, and a specific 8-h limit value of 0 ...

  7. 23 Νοε 2019 · Aldehydes and volatile organic compounds (VOCs) are chemicals categorized with boiling points from 50–100 °C to 240–260 °C; therefore, they can be found indoors in the gaseous phase. Formaldehyde is a dominant aldehyde found indoors.
