The People’s Republic of Chemicals

The name of China is almost obscured by a grey smudge on the title page of The People’s Republic of Chemicals, and this image proves to be apt.  This book examines the crisis caused by toxic smogs that periodically choke vast regions of China and the massive particulate clouds that drift far beyond the country’s borders.

Authors William J. Kelly and Chip Jacobs joined forces once before in order to write their climate classic, Smogtown: the Lung Burning History of Pollution in Los Angeles, a remarkable 2008 exposé and memoir about air quality, politics and health in Southern California’s smog belt. This time, the duo of self-described “smog gumshoes from Los Angeles” go farther afield to investigate air pollution that threatens to put a chokehold on the Pacific Rim. What’s more, Mandarin editions of both books will be available through the Central Party School Publishing House.

No doubt the translators were challenged to render some of the exaggerated gonzo phrases and slang from this “murky yarn of atmospheric pain and karma” into prose that doesn’t come across as glib or simply baffling.

“Ashtray-skied towns” abound and burning coal “cruds its troposphere like cigar smoke in a closet.”  Beijing is described as “the city where your oxygen sometimes came spiced with black char.” A chapter entitled “Tweets for the Wheezy” notes that “a Twitter account had economic superpowers throwing each other the stink eye.” It goes on to describe how the U.S. Embassy in Beijing inadvertently raised a ruckus in 2009 and 2010 by posting hourly readings of particulate pollution as measured on the roof of their former compound. Intended as a service for American travellers and embassy staff, the air quality statistics appeared on @BeijingAir, an embassy-run Twitter page, and showed that the capital’s atmosphere frequently was less healthy than the official daily averages posted by China’s Environmental Protection Bureau would indicate. Chinese officials took umbrage and tried to block the public’s access to these damning numbers.  It’s obvious that Kelly and Jacobs are relentless researchers, and they don’t hide a heavy reliance on secondary sources. They readily confide: “We Googled until our fingers tingled. Then we gasped.”
...
U.S. President Bill Clinton also emerges as an eco-villain. Although Clinton championed environmentalism in the United States, Kelly and Jacobs note how the bilateral trade deals made during his administration got the American consumers hooked on inexpensive Chinese goods. Prices were kept abnormally low because of China’s cheap but dirty energy sources and sweatshop wages paid to labourers. But exporting dirty manufacturing to China could not outsource pollution indefinitely, particularly when antiquated or wasteful methods were used there without modern filters. Regrettably, no provisions prevented China from financing highly contaminating coal-based projects.

“In post-W.T.O. China, something biologically creepy was only a factory pipe away,” the authors observe. They conclude that ultimately, the world cannot escape the consequences of carbon gluttony on its climate. Kelly and Jacobs urge President Xi Jinping “to make eco-restoration as much his legacy as ridding the party of the endemic graft he so loathes.”

A Yankee Inventor Takes On Beijing Smog

On days when Beijing’s heavy air pollution is especially pungent, you can smell and taste the acridity—whether you’re outside on the street or inside most buildings. Air pollution doesn’t stay outdoors but seeps inside through open doors and window sealings. On most days, levels of dangerous pollutants, such as PM 2.5, are somewhat lower outside than inside, but not much lower.

This unhappy fact has fueled a growing market for pricey indoor air filters in China, made by such companies as Chicago’s BlueAir and Switzerland’s IQAir. A basic model will set you back at least $800. And ideally, you should have one for each room in your home, school, restaurant, or office. In other words, these filters don’t come cheap.

But what if there’s a simple but less costly way to achieve roughly the same effect? Now there might be.

During the Beijing “Airpocalypse” of January 2013, Thomas Talhelm, a Fulbright scholar spending a year in China, began to research how air filters worked. Soon Talhelm realized that the essential components—a HEPA filter, a fan, and a velcro strap to hold them together—could be purchased on Taobao, China’s leading e-commerce site, for less than $35. So he rigged up his own air filter and invested in a scientific particle monitor to see how well it worked. (The DC1100 Pro Air Quality Monitor, which measures levels of PM 0.5 and PM 2.5, was more of a splurge, at $260.)

Using a HEPA filter strapped to a simple flat-surfaced fan, he found that the device reduced indoor levels of PM 0.5 by 84 percent and indoor levels of PM 2.5 by 92 percent. When he tested a more powerful rotating fan, the results were even better. His DIY device lowered indoor levels of PM 0.5 by 97 percent, and indoor levels of PM 2.5 by 96 percent. (The expensive premade air purifiers he tested had similar results.)
