Growing demand from public health research for conduct large-scale epidemiological studies to explore health effect of PM2.5 was well-documented. To address this need, we design a web-based real-time personal PM2.5 exposure monitoring system (RPPM2.5 system) which can help researcher to get big data of personal PM2.5 exposure with low-cost, low labor requirement, and low operating technical requirements. RPPM2.5 system can provide relative accurate real-time personal exposure data for individuals, researches, and decision maker. And this system has been used in a survey of PM2.5 personal exposure level conducted in 5 cities of China and has provided mass of valuable data for epidemiological research.
Keywords: Big data; Personal exposure assessment; RPPM2.5 system; Real-time PM(2.5).
