An independent investigation by The Guardian found 33 cities in 17 US states (including Chicago, Boston, Philadelphia, Detroit and Milwaukee) are systematically cheating on the tests to monitor lead levels in the municipal water. 21 of those cities used the same cheating techniques that led to criminal charges in the Flint water scandal.

A leaked recording made of a conference call hosted by the Edison Electric Institute, which lobbies for the power industry, reveals lobbyists for high pollution companies talking about how they can exploit the Syrian refugee crisis to get a rider inserted into a pending bill that would kill the EPA's Waters of the United States rule, which protects America's waterways from pollution.

In Beijing, China banned 2.5 million cars from driving for 2 weeks to get this beautiful blue sky for a World War II commemorative parade. As soon as the parade was over, the ban was lifted, and the blue vanished within 24 hours. Read the rest
Researchers at the University of Toronto found that “badly tuned” cars are responsible for most of the air pollution. Read the rest
Reporting this week at the annual American Geophysical Union, scientists from UC Irvine discussed air quality results from samples taken during the 2012 and 2013 Hajj.
The annual pilgrimage brings between 3-4 million people to the holy city of Mecca. Isobel Simpson, the lead researcher on this project, stated that, "The problem is that this intensifies the pollution that already exists. We measured among the highest concentrations [of smog-forming pollutants] our group has ever measured in urban areas – and we’ve studied 75 cities around the world in the past two decades.”
The worst locations were tunnels leading into the Grande Mosque where carbon monoxide levels were up to 300 times higher than baseline measurements, and pedestrians were often walking in large numbers alongside idling motor vehicles. Increases in carbon monoxide are linked to increased numbers of hospitalizations and deaths from heart failure. In addition to carbon monoxide, the team found elevated levels of benzene, black carbon, and other fine particulates that can affect lung function.
The main culprit here that can be addressed by the Saudi government is a lack of regulation over automobiles, gasolines, and exhausts. Currently, there is a significant lack of public transportation in the area, and nearly everyone owns a car. Those cars don't have the devices that are currently required and built into vehicles in the Unites States to limit pollution.
The easiest thing to fix would be separating pedestrians from cars in the tunnels, or at least spreading vehicles out more evenly among the tunnels leading to the Mosque, so that pollutants don't build up as much and negatively affect those walking in. Read the rest
Greenpeace this week released a report on soil and rice crops sampled in villages close to a concentration of heavy metals smelters in China's Hunan Province, "an area that ranks first in rice output and among the top five in nonferrous metals production." The results showed that both rice and soil near the industrial complex are contaminated by heavy metals, including lead. "12 out of all 13 rice samples contained excessive levels of cadmium." Read the "Cadmium rice" report at Greenpeace East Asia. Here's a related piece at the New York Times. Read the rest
Speaks for itself, doesn't it? NASA:
When the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite acquired this image on December 7, 2013, thick haze stretched from Beijing to Shanghai, a distance of about 1,200 kilometers (750 miles). For comparison, that is about the distance between Boston, Massachusetts, and Raleigh, North Carolina. The brightest areas are clouds or fog. Polluted air appears gray. While northeastern China often faces outbreaks of extreme smog, it is less common for pollution to spread so far south.Read the rest
