A Hazy Outlook over the North China Plain

Beijing, the cultural and political capital of China, is home to a massive population of almost 25 million people has long been known for its air pollution. A team of scientists at Peking University in Beijing looked at the chemistry of the city’s haze and found something surprising: the inorganic mass fraction, normally dependent on only human activities, increased with increasing relative humidity. That’s right: how bad anthropogenic emissions actually are depends on the weather. Exploring this trend will help us to understand how haze forms, which could help Beijing and other major cities to manage their air pollution problems more effectively.

Reviving Our Rivers

Most rivers in the developed world are mere artifacts of what they once were – wild dynamic beasts that wiggled across the landscape recycling old land and creating new surfaces. With human development came the desire to manage water movement, and now most rivers flow through static channels held in place by levees and controlled by dams. But recently some regions are making efforts to give rivers a bit more freedom and restore their associated floodplains.

Betcha won’t drink it! The natural chemicals hiding in water, and how a new technique hopes to remove them using an unlikely ally- bacteria

The amount of natural organic matter, or NOM, in water has been increasing for the past 20 years and is expected to increase. Higher amounts of NOM mean more expensive clean water- a high priority especially when considering communities at risk for clean water shortages due to storms. Environmental engineers work on ways to reduce NOM effectively in drinking water treatment plants, and sometimes, this means making unusual allies: bacteria.
