Atmospheric (Smoke) Heavy Metals

 Atmospheric particulate matter is a major atmospheric pollutant with large quantities, complex composition, diverse properties, and significant harmful effects. Heavy metal pollutants in atmospheric particulate matter are persistent, and the bioavailability of metal elements varies depending on their chemical forms. The long-term presence of heavy metals poses a significant potential threat to the environment. Traditional detection methods rely on offline monitoring, which involves noticeable hysteresis, time-consuming sample preparation, high costs, and can lead to sample contamination and deviations in detection results. Online atmospheric heavy metal monitoring devices can track the concentration of heavy metals in the atmosphere in real time, improving the timeliness and accuracy of monitoring and providing valuable support for timely warnings and preventive measures.
