A recent article on the quality of the air in China began with this frighening statistic: Outdoor air pollution contributed to 1.2 million premature deaths in
in 2010, nearly 40 percent of the global total. Brought into the headlines during the Beijing Olympics, the poor quality of the air in China is nothing new.
In February 2012, the China State Council passed ambient air quality standards, GB 3095-2012. The goal of these improved standards is to improve both the environment and the health of those living there. with the aim of improving the living environment and protecting human health. For the first time, particulates with a diameter of 2.5 microns or less, also known as PM2.5, is included in the standards. PM2.5 are the smallest particulate matter and penetrate the body’s tissues most deeply. Once inhaled, the particles may cause respiratory infections and are especially dangerous for children and the elderly, as well as those with existing respiratoy issues. Ozone levels are also set in the standard with the new 8 hour ozone standards matching the interim targets set by the World Health Organization (WHO).
For years, Chinese officials had been collecting the data but failed to release it publically. The US embassy in Beijing posts automated air quality measurements on an hourly basis at @beijingair. Last June, there was debate over the accuracy of the readings due to large disparagies between the readings by Chinese officials and the embassy. Chinese authorities asked that they and other stop publishing, what they described as "inaccurate and unlawful" data.
By early this year, many news reports emerged that the air quality in Beijing has reached hazard ous levels. With 100 being the maximum "safe" level and 300 being a level at which those at risk should remain indoors, reports in Beijing ranged from 400-800 micrograms.
The timeline for implementing the new standards is January 2016. Some cities may be required to implement the changes ahead of this date, as determined by Ministry of Environmental Protection. Overall, provinces are being encouraged to implement the new standards as soon as they are ready.
From time to time, we like to showcase the research of our customers. Our team is always interested in learning more about the huge variety of research projects and discoveries made in labs using Environics systems.
Recently, we received a note from Ying Wang at the University of Connecticut on a research project utilizing an Environics 4000 gas mixing system. Ying is a member of Dr. Yu Lei's lab in the department of Chemical, Materials & Biomolecular Engineering. The lab has two main areas of study. First is the development of various (bio)sensors, whose uses range from the diagnosis, drug discovery, screening and food safety, and pollutant monitoring. Recent work has also involved the detection of biological and chemical agents. The second focus is the synthesis of nanostructured materials and their application, with the goal of developing new nanomaterials that can be applied to the fields of sensing and biosensing.
A recent paper published in RSC advances, the researchers utilized their Environics system in the fabrication and testing of a sensor device which featured a aligned CuO nanowires capable of H2S detection. Sensitivity was examined under a variety of conditions, including levels between 10 to 1000 ppb and temperatures from 25 to 420 °C. The CuO nanowire sensor showed a detection limit of 2.5 ppb and a linear response range of 10 ppb to 100 ppb.
Have an interesting project using your Environics system? Share it with us and you may be the included in our next focus!

Here in CT, we are entering the months where unhealthy air quality emerges with the heat levels this summer. The American Lung Association has released an new advertising campaign featuring TV, online and billboard ads announcing the new State of the Air® smartphone application. The app, available for iPhone and Android, allows users to view EPA collected data on the air quality at their current location or at any other location of choice. Read this post to learn more about this data. The app is being praises as a user-friendly resource for people for low air quality affects most profoundly, those living with lung disease (such as asthma, people with heart disease or diabetes and the elderly and children.
ALA of the Northeast President and CEO, Jeff Seyler, was quoted to say, “We are excited to be able to provide this innovative tool so those with lung disease, and without, can effectively monitor their local air quality and limit their exposure to dangerous levels of pollution.”
The State of the Air app provides both the current and next-day air quality forecasts. Users can set alerts to notify them when the local air quality fails to a code orange, which is unhealthy for sensitive groups. Along with the quality information, the app provides tips on what activities are to be avoided depending on the current conditions.
The television and online messages are aimed at young people. They feature Alvin Grimes, an air collector, who collects air samples in glass jars. The promos tie into the ALA tagline "What are your lungs collecting?" "Alvin" has his own, twitter account and facebook page where he shares tips and information on air and air pollution. The TV spots can be viewed on his youtube page (one example below).
