空气负离子与健康

Discussion of Negative Air Ion and Health

作为衡量和评价空气质量高低的重要指标之一,空气负离子(negative air ion,NAI)浓度对生活区和旅游区环境质量的改善有重大意义。阐述了NAI的产生机理及其对人体内外环境的保健作用,讨论了城市环境、海滨环境和森林环境对空气NAI和人体健康的影响,为改善生活质量提供了科学参考,同时,为城市中人们的日常活动或休假给出了健康效益更高的建议。

As one of the important indicator reflecting air quality,the concentration of negative a ir ion(NAI)is of great significance to the improvement of the living environment and the environmental quality of the tourist areas.This paper expounds the generation mechanism of NAI and its effects on human health,and discusses the effect of city environment,coastal environment and forest environment on the air NAI and human health.The paper provides scientific reference for improving the quality of life,and it gives more effective and beneficial advice about people’daily activities or vacation in the city.
