Toxic dust emission from drought-exposed lake beds – a new air pollution threat from dried lakes
2025
Abstract. Many lakes worldwide are shrinking rapidly due to climate change and human activities. Pollutants accumulated in dried lake bed sediments may be released into the atmosphere as dust aerosols. However, whether lake bed dust carries sufficient toxic m…

Stimulated Emission

Release of a photon triggered by another

Stimulated emission is the process by which an incoming photon of a specific frequency can interact with an excited atomic electron (or other excited molecular state), causing it to drop to a lower energy level. The liberated energy transfers to the electromagnetic field, creating a new photon with a frequency, polarization, and direction of travel that are all identical to the photons of the incident wave. This is in contrast to spontaneous emission, which occurs at a characteristic rate for each of the atoms/oscillators in the upper energy state regardless of the external electromagnetic field.

Toxic dust emission from drought-exposed lake beds – a new air pollution threat from dried lakes
2025
Abstract. Many lakes worldwide are shrinking rapidly due to climate change and human activities. Pollutants accumulated in dried lake bed sediments may be released into the atmosphere as dust aerosols. However, whether lake bed dust carries sufficient toxic materials and exceeds threshold atmospheric concentrations to pose a significant health risk is currently unknown. Recently, Poyang Lake and Dongting Lake, the largest lakes in east China, experienced record-breaking droughts, with 99 % and 88 % areas exposed t…
