Airborne hydrogen cyanide measurements using a chemical ionisation mass spectrometer for the plume identification of biomass burning forest fires [PDF]

, 2013
A chemical ionisation mass spectrometer (CIMS) was developed for measuring hydrogen cyanide (HCN) from biomass burning events in Canada using I− reagent ions on board the FAAM BAe-146 research aircraft during the BORTAS campaign in 2011.

Measurement of HCN in the middle atmosphere by EOS MLS [PDF]

, 2006
The EOS MLS instrument on NASA's Aura satellite has made the first continuous global measurements of HCN in the middle atmosphere. The measurements are in broad agreement with most earlier measurements, showing HCN to be a long-lived tracer with sources ...

What causes the irregular cycle of the atmospheric tape recorder signal in HCN? [PDF]

, 2010
Variations in the mixing ratio of long-lived trace gases entering the stratosphere in the tropics are carried upward with the rising air with the signal being observable throughout the tropical lower stratosphere.

Effect of Fermentation on Cyanide and Ethyl Carbamate Contents in Cassava Flour and Evaluation of Their Mass Balance during Lab-Scale Continuous Distillation

Foods, 2021
When cassava is used for the production of distilled spirits through fermentation and distillation, toxic hydrogen cyanide (HCN) is released from linamarin and carcinogenic ethyl carbamate is produced.

Electron deficient imine-based receptor for selective colorimetric recognition of cyanide ion through aromatic CH•••anion interactions

Journal of Photochemistry and Photobiology, 2021
An electron withdrawing natured di-nitro substituted, imine based receptor L has been designed and synthesized. Naked-eye colorimetric experiment and UV–vis spectrometric studies reveals that the receptor L selectively binding the cyanide anion through C–
