File photo shows children wear face masks on a smoggy day in Beijing. (PhotoChina News Service) The quality of protective face masks sold across China will soon be required to reach a minimum national standard to overcome industrial disruptions Nike Air Max 2019 Por Mayor , the China Business News reported on Friday.
The face mask industry has no corresponding association or system for quality and market management, even though the profits of some brands have increased by up to a few hundred percent in recent years, the report said.
According to a quality inspection report from the Shanghai Bureau of Quality and Technical Supervision, out of 69 random samples, over 80 percent of the products failed to meet requirements for protection against PM2.5.
Some well-known brands were among those with unqualified products, namely 3M and BlueShields http://www.airmaxpormayor.es/ , which have been found selling substandard masks, while Yunnan Baiyao saw the lowest filtration efficiency at only 24.2 percent.
"This is also what we are most concerned about, that the chaos will lead to a continued slowdown in consumer confidence," says Lin Jinxiang, chairman of the ZheJiang Occupational Safety and Health Goods Association and general manager of Chaomei Daily Chemical Corporation Ltd. in Jiande City.
In response to non-standard industrial competition, the need for a new national standard for face masks was officially put on the agenda in 2014.
According to authorities Nike Air Max España , the China Nonwovens and Industrial Textiles Association, the Jiangsu Quality Supervision and Inspection Center for Special Type Products of Safety Protecting, the National Quality Supervision and Testing Center for Labor Protection Products, and other professional enterprises will be in charge of drafting technical regulations for the daily use face-mask industry.
Masks that do not seal tightly to the face result in a high leakage rate and will not block dust and fine particulate matter, so a mask's leakage rate and respiratory resistance are important factors for such a standard, says Lin.
"However Nike Air Max Baratas , I have not received any information regarding the new national standard," he says, adding that it will be a self-contained system combining the characteristics of medical masks and industrial masks.
TORONTO, Jan. 6 (Xinhua) -- A group of Canadian scientists are studying the sounds of animal activity to predict long-term species sustainability and measure effectiveness of land reclamation, which they see as "listening in on climate change," said a media release from University of Alberta Wednesday.
A university researcher is successfully driving bioacoustics technology to record the soundscapes of Alberta wildlife. One of the ultimate goals of the project is to track the effects that climate change is having on our animal population.
"Technology has changed the way we survey for wildlife Nike Air Max Por Mayor ," said Erin Bayne, associate professor of biological sciences at the University of Alberta. "If it makes a sound, we can count it. This is giving us a whole new insight to animal behavior."
Bayne, along with his team of graduate students, is working with the Alberta Biodiversity Monitoring Institute (ABMI) on the new initiative. "In the past, people would basically go out in the woods Nike Air Max Tavas Por Mayor , look for animals, stand there, listen for them, count them, and then walk away. You got only one snapshot," said Bayne.
The bioacoustic unit uses new technology to continuously record soundscapes up to months at a time. The group is working to have computers automatically identify species sounds Nike Air Max Typha Por Mayor , and they are also creating a central repository so that citizen scientists can assist with data entry.
"These machines are out there all the time. We are getting data on species that nobody has ever really monitored before, because some of them call at 10 o'clock at night or two in the morning," times when the average bird watcher isn't necessarily out monitoring. "We've found things that we never would have found by just having people do it."
Their efforts are helping track the effects of climate change on long-term species sustainability. "One of the predictions is that migrating animals won't be able to keep up with the changes. We've never really known the exact timing when these animals arrive back for the season."
Bayne noted that this new technology will allow a series of these machines from Edmonton, the provincial capital city of Alberta, all the way to the Northwest Territories to track the exact arrival of the return of the migrating species. "We will know exactly when the birds arrive at any given point along that trajectory, and we can start to track the changes in their arrival times year to year."
Bayne and his collaborators are also engaging technology to determine exact locations of the animals. "Sound travels at a fixed rate. If you put out three of these monitoring units and know the exact time when the sound was recorded Nike Air Max 120 Por Mayor , you can triangulate back and say, 'the bird was right there.'"
He noted that this is useful as a tool for assessing the effectiveness of land reclamation efforts by the energy and forestry sectors. "We can now tell you whether birds are using trees planted along seismic lines, for example."
Industry is using the technology to monitor for their environmental impact assessments. Along with ABMI, Bayne is pushing this new technology to become the provincial standard monitoring protocol in west Canada.
