Liumitai-mounted negative oxygen ion detector—yesterday morning’s data was: 2320
Limumtai Scenic Area, Jixian County, Tianjin 11 Successfully awarded national status this month. 4A A scenic area of a certain grade, here due to the forest coverage rate… 95% Above, the number of plant varieties reaches as many as 600 With a variety of springs and waterfalls winding throughout the scenic area, it has long been known as a “natural oxygen bar.” To make its renowned reputation immediately apparent, 15 On [date], the scenic area management committee installed negative oxygen ion monitors within the park to continuously track and update real-time levels of negative oxygen ions.
16 At nine o’clock in the morning, near the restaurant nestled among the scenic mountains and waters, a large… was spotted. LED The display screen informs visitors that the current concentration of negative oxygen ions in the scenic area is per cubic centimeter. 2320 units. This is far above the World Health Organization’s standard for clean air, which sets the concentration of negative oxygen ions at per cubic centimeter. 1000 to 1500 One.
Airborne negative oxygen ions, owing to their diverse benefits—including dust reduction, sterilization, increased blood oxygen levels, enhanced physical health, and therapeutic effects—are often referred to as “air vitamins” and “longevity factors.” They exert a profoundly important influence on the life processes of humans and other organisms. In China, negative oxygen ions are commonly classified into… 6 a grading standard, wherein, 1 The concentration of negative oxygen ions is less than or equal to 500 Typically, the corresponding environments include factory buildings, urban interiors, and street green spaces, among others. 2 Negative oxygen ions of grade 500 one to 900 A common corresponding environment is parks, among others; 3 Negative oxygen ions of grade 900 one to 1200 A common corresponding environment is the wilderness, among others; 4 Negative oxygen ions of grade 1200 one to 1800 One, the typical corresponding environment is mountain tops, etc.; 5 Negative oxygen ions of grade 1800 one to 2100 A, the typical corresponding environments include forests, among others; 6 The concentration of negative oxygen ions is greater than or equal to 2100 Typically, the common associated environments include forests and waterfalls.
Experts analyze that negative oxygen ions are generated in three main ways: first, in forests; second, in the natural environment, where atmospheric molecules undergo ionization under the influence of ultraviolet radiation and cosmic rays, releasing electrons and thereby producing negative oxygen ions; and third, during processes such as waterfalls crashing, gentle waves rolling, and heavy rain falling, when water molecules break apart, negative oxygen ions can also be formed.
According to景区 staff, under normal conditions, the concentration of negative air ions is higher on sunny days than on overcast ones, greater in summer than in winter, and at noon than in the early morning or late evening. “With winter now upon us, most of the trees in the scenic area have shed their leaves, and the streams are beginning to dwindle, so the level of negative ions is far lower than during the lush summer months when forests are thick with foliage and springs and waterfalls abound. Even so, these monitoring figures remain quite impressive,” the staff noted. They speculate that the reason Lìmùtái Scenic Area continues to produce such a high concentration of negative ions even during the dry season is directly linked to the extensive coniferous forests within the area—though this remains an assumption and should be verified.
No wonder many locals and tourists find that, though they arrive utterly exhausted, they instantly feel refreshed as soon as they reach Limutai. No matter how strenuous the hike or sightseeing, a short rest leaves them feeling relaxed, and few ever leave Limutai still weighed down by fatigue.
