Article Synopsis
  • Cigarette butts (CBs) are a major global waste issue and can leach toxic phenolic compounds (PhCs) into aquatic environments, but research on this phenomenon is limited.
  • *The study tested different types of CBs—freshly smoked, aged, and their components—for PhC leaching over time, finding high levels of certain PhCs from freshly smoked filters and paper.
  • *Ecological risk assessments indicated that the leachates from all CB types pose significant risks to organisms like algae, Daphnia magna, and fish.

Exhaled breath analysis is evolving into an increasingly important non-invasive diagnostic tool. Volatile organic compounds (VOCs) in breath contain information about health status and are promising biomarkers for several diseases, including respiratory infections caused by bacteria. To monitor the composition of VOCs in breath or the emission of VOCs from bacteria, sensitive analytical techniques are required.

Article Synopsis
  • Nicotine from discarded cigarette butts (CBs) can pollute water systems and potentially harm aquatic life due to its toxicity.
  • Different parts of CBs release varying amounts of nicotine: remaining tobacco and ash leach the most, while filter and paper leach the least.
  • An estimated 380-7065 tons of nicotine could enter water bodies each year from littered freshly smoked CBs, posing a significant ecological risk.

Qualitative and quantitative on-site detection methods for wood preservatives are of high value for the recycling industry and the occupational health and safety. Wood preservatives revealed as toxic to human and environment after decades of use. For the detection of contaminated wood and for processing of matured timber to particle boards a versatile detection method is needed.
