CAS Key Laboratory of Aerosol Chemistry and Physics (KLACP), IEE CAS


The Key Laboratory of Aerosol Chemistry & Physics (KLACP), affiliated with the Institute of Earth Environment, Chinese Academy of Sciences (IEECAS), is directed by Prof. Junji CAO. The chairmen of the academic committee of KLACP are academicians Zhisheng AN and David Y.H. PUI. Many KLACP young scientists have won worldwide recognition in aerosol sciences, have been chosen as the main principal investigators in national projects or have been nominated as ‘National Funds for Distinguished Young Scientists’ as well as ‘Hundred Talents Program’ of Chinese Academy of Sciences.

KLACP focuses on the central issues of aerosol sciences and the pressing needs of the country, playing an active role in establishing substantive and sustainable collaborations with world-renowned research groups. Successions of scientific achievements were gained from original research in the field of mineral dust, black carbon, organic aerosol and PM2.5, the results of which have produced significant impacts both nationally and internationally.

After over two decades’ efforts, KLACP is stepping up on the international stage as an important organization in aerosol research. The lab takes full advantage of a closely-integrated approach containing field experiment, laboratory analysis, and numerical modeling to address the forefront scientific questions in aerosol research, particularly aiming at the physical‒chemical‒biological processes of black carbon and organic aerosols as well as their impacts on climate and environment. By aligning the theoretical and technical development with our national needs, and exploring aerosol pollution control technology in industrial applications, KLACP has been constructed into a comprehensive integrated system covering aerosol sample analysis for its physical/chemical/optical characteristics, real-time online analysis with high-resolution and multi-species capability, as well as aerosol modeling.

In the foreseeable future, KLACP will develop into a national innovation center as a frontrunner for aerosol science both in China and internationally. The lab will provide a high-level training base for aerosol scientists, will guide the direction of aerosol research in China and will provide substantial contributions to the sustainable development of society and the economy as well as protection of the environment and ecosystems.

Lifting the fog on the Great Smog

The ‘Great Smog’ that killed thousands of people in London in 1952 was triggered by a chemical process currently causing hazy days in China’s megacities.

A major culprit behind London’s fatal fog was sulfate (SO42-) that built up due to increased sulfur dioxide (SO2) from burning coal. How the sulfate formed and why it became so lethal was less clear. A team including researchers from the CAS Key Laboratory of Aerosol Chemistry and Physics in Xi’an, China, studied hazy air in Beijing and Xi’an and found that sulfate forms when nitrogen dioxide (NO2) oxidizes SO2 under specific atmospheric conditions. The reaction occurs either on tiny airborne particles in the presence of ammonia (NH3), or on cloud droplets.

The authors conclude that ammonia from agriculture contributes to China’s pollution problem, yet also prevents sulfates in Beijing and Xi’an from becoming dangerously acidic, whereas in London’s smog, the cloud droplets evaporated each day, leaving behind particles of toxic sulfuric acid.
