[Photo/VCG] BEIJING - Air quality in the Beijing-Tianjin-Hebei region improved in the first four months of 2018 compared with the same period of last year, according to the Ministry of Ecology and Environment. Good air days accounted for an average of 59.1 percent of total days in the 13 cities in the region, up 2.2 percentage points year on year, the ministry data showed. The density of PM 2.5, a key indicator of air pollution, dropped 18.8 percent year on year during the period, while the density of PM 10, another major pollutant, fell 12.9 percent. Beijing saw the ratio of good air quality days increase by 3.9 percentage points to 64.7 percent in the period, with PM 2.5 and PM 10 density down 22.4 percent and 9.9 percent, respectively. Nationwide, 338 cities had an average of 76.7 percent good air quality days, up 0.9 percentage points year on year. However, air quality in April alone worsened in the Beijing-Tianjin-Hebei region. The average proportion of days with good air quality was 58 percent, down 13.7 percentage points from April last year, with lower PM 2.5 density but higher PM 10 density. A ministry statement attributed the decrease from the previous month to frequent sandy and dusty days, increased industrial and construction activities, and static weather patterns, which make it difficult for airborne pollutants to disperse. Tackling pollution has been listed by the government as one of the three tough battles that China aims to win in the coming three years. 24 hour silicone wristbandsharley davidson silicone wristbandmedical id silicone wristbandssilicone wristbands free shippingwhere to buy colored wristbands
Qinghai-Tibet Plateau, which is part of the Pan-Third Pole. [Photo/VCG] BEIJING -- Chinese research institutions launched a project to conduct water and biodiversity research under climate change in the Pan-Third Pole, according to Chinese Science Daily on Wednesday. The project, featuring 16 institutions, will study the mechanism between water, typical ecosystems and climate change, as well as conduct continuous monitoring and evaluation research on water and biodiversity. Researchers will work together to find the reasons behind and solutions to the degradation of the alpine grassland ecosystem of the Qinghai-Tibet Plateau, the slower growth of the artificial breeding yaks and the influence of glacial recession on the plateau's aquatic organisms. Extended westward and northward from the Third Pole, the 20 million kilometer Pan-Third Pole encompasses the Eurasian highlands, according to the Institute of Tibetan Plateau Research of Chinese Academy of Sciences. The researchers will establish a water and biodiversity database for the countries along the Silk Road to provide theoretical support and management strategies for pushing forward the ecological protection of the Qinghai-Tibet Plateau, the newspaper said. The project is affiliated with a Strategic Priority A Program of the Pan-Third Pole Environment Study for a Green Silk Road which was launched by CAS in 2018. The program is designed to integrate basic science, applied studies, technology innovation and policy-advising. pink breast cancer silicone wristbandscolor filled wristbandcustom braceletscustom word braceletrubber wrist bands<%2fcenter>
