An eco-environment industry-academia alliance under China Association for Science and Technology has unveiled the top 10 programs that represent the scientific and technological progress China made last year in the environmental protection sector, in Beijing on Monday, the World Environment Day.

One of them, for instance, is a research program on technologies and management system for the conservation and remediation of the Yangtze River, Asia's longest watercourse.

To beef up Yangtze conservation, the Ministry of Ecology and Environment launched the National Joint Research Center for Yangtze River Conservation in 2018. Then, over 5,000 researchers from 269 research institutions across the country were dispatched to 58 cities along the trunk of the Yangtze for the joint research.

Since it was implemented, the joint research has not only identified the causes to the outstanding water environmental problems in the Yangtze basin, but also managed to introduce a series of solutions, which have been applied in 58 cities and supported continuous water quality improvement in the river, the alliance said in a press release on Monday.

Another selected program is about noise pollution management, which the alliance stressed as being closely related people's daily life.

A team mainly supported by members with China National Environmental Monitoring Center has established an institutional system for noise pollution control, it said. The system can offer technical supports for the enactment of legal system, standard system and policy measures for noise pollution governance.

The others of the 10 programs include the control of heavy metal pollution in soil, nitrogen and phosphorus management in lakes, remote sensing for atmospheric aerosol detection and synergizing air pollutants and greenhouse gas emissions in the steel sector.
