Effect of Meteorological Factors on an Event of Non-occupational Carbon Monoxide Poisoning / 环境与健康杂志

ABSTRACT

Objective To discuss the influence of weather process on the event of non-occupational carbon monoxide poisoning. Methods The weather data on the event of carbon monoxide occurred on February 18, 2001 (2.18 event) such as weather position, air stability, mixed layer depth, inversion layer, air temperature, air pressure, wind speed and observation of 255 meters meteorological tower were analyzed. Results The 2.18 event happened under the conditions including warm ridge in higher level, depression system, calm or breeze, air temperature increasing in the surface, inversion layer enhanced, mixed-layer depth lowering. Conclusion The weather factors such as the higher and low layer atmosphere circumfluence position, wind from surface, air temperature, pressure and mixed layer depth produce an integrated effect on the non-occupational carbon monoxide poisoning.
