Salt in Air: Beyond Sea Spray in Coastal City Pollution Exciting News for Air Quality Monitoring! A study by Dr. Xiaorui Wu at NUS Environmental Research Institute (NERI) and NUS Department of Civil & Environmental Engineering has improved the air pollutants characterization method by distinguishing airborne salts emitting from natural sea spray from human activities, especially for coastal cities. This upgrades the method with a new capability to better pinpoint sources of fine particulate matter (PM₂.₅), which could be associated with health concerns of respiratory and cardiovascular issues. Stakeholders can now better identify how much PM₂.₅ comes from natural sea spray and various human-driven activities. This can enable policy making to target the right sources to improve urban air quality, a stepping stone to meet the tough goal PM₂.₅, an annual concentration of 5 µg/m³, recommended by the World Health Organization. Assoc Prof Liya Yu, the advisor of Dr. Wu’s research work, commented that the work is built upon a team effort, studying the chemical composition of PM₂.₅ studied by many researchers in the group. “The research work is similar to detective’s job, or a type of forensic work about PM₂.₅.”, she said. She envisions that the similar technique can be fine-tuned to apply to other inland areas, beyond the coastal region. Applause to the team for this impactful contribution to environmental science!

Why 0.5 and 5.0 microns particles measurement⁉️ Did your ever think about why we select 0.5 and 5.0 microns particles measurement in cleanrooms qualification as a common practice.... And What about less than 0.5 microns and more than 5.0 microns? To answer this question, we need to know that The main aim of the clean room is to control the presence of the viable particals or living organisms ( ex. Bacteria🦠🦠) But These viable particles or living organisms are not able to move from one place to another place in cleanrooms, unless they found source or carrier for their movement. Non-viable particles in cleanrooms work as that transporter or carrier for these living organisms which attach to the surface of non-viable particles and move from one place to another place with the help of air movement. Now, ( where the answer) 👇👇 1️⃣ During particle count, we measure only 0.5 and 5.0-micron particles because most of the commonly found bacteria are in the size range of 0.5 to 5.0 micron so this is the suitable size range 2️⃣why we don’t measure less than 0.5 micron is that, microorganisms find it very difficult to attach particles less than 0.5-micron size. and If the microbes attach to the particles greater than 5.0 micron then these particles become heavy and are not transported along with air movements but settle down on the ground. So that range is representing possible main source of contamination and with the measurements will give clear indication of the clean room status and classification
