China says 75 percent of cities failed to meet air standards in June | Reuters

Nearly 75 percent of China’s big cities failed to meet air quality standards in June, the environment ministry said on Monday, an improvement over the same month last year, as the country continues to wage “war on pollution.”

Nineteen cities met air quality standards every day, the Ministry of Environmental Protection said in a statement on its website (www.mep.gov.cn), compared to five at the same time last year.

Air quality in the capital Beijing was subpar on almost 60 percent of the days in June and saw levels of PM2.5 – particulate matter with a diameter of 2.5 micrometers that can penetrate deep into the lungs – rise 11 percent compared to the same period last year.

Amid growing public disquiet about smog and other environmental risks, China said last year it would “declare war on pollution” and it has started to eliminate substandard industrial capacity and reduce coal consumption.

Last year, nearly 90 percent of China’s 74 big cities failed to meet air quality standards.

The state standard is 35 micrograms of PM2.5 per cubic meter, but the government does not expect to bring the national average down to that level before 2030.

In April, the vice minister for environmental protection announced a two-year inspection campaign to root out fake air quality data and accused some local governments of manipulating the data to meet national standards.

Pollution in Delhi Prompts U.S. Embassy Warning – India Real Time – WSJ

If you have children in New Delhi, you might not want to let them play outside today. The U.S. Embassy in the Indian capital said air quality – as measured at a monitoring station in the embassy compound – had reached “very unhealthy” levels on Wednesday morning.

On Wednesday at 10 a.m., the embassy said its air-quality index was 255 – a measure based on the amount of fine particulate, or PM 2.5, in the air. Such small particulates can enter the lungs and blood stream. They have been linked to severe health problems such as lung cancer.

The U.S. Embassy’s website said that an air-quality index reading between 201 and 300 can cause “significant aggravation of heart or lung disease” and a “significant increase in respiratory effects in general population.”

“Older adults and children should avoid all physical activity outdoors,” it said. “Everyone else should avoid prolonged or heavy exertion.”

The message though hadn’t got through to the American Embassy School in Delhi on Wednesday morning. Kailash Sharma, a staff member at the school, which is located across the road from the embassy, said by telephone that “kids were playing outside.”

The U.S. embassy in Beijing, China, also monitors air pollution.

Delhi’s air quality often deteriorates in winter, particularly in the days after the festival of Diwali when residue from fireworks displays adds to pollution levels.

India’s Ministry of Earth Sciences on Wednesday said its air-quality index was 121, a level described as “poor.”
