Air quality in Shanghai worsened last week compared with the previous week, according to the latest report from the Shanghai Environment Monitoring Centre.

The average air pollution index (API) for sulphur dioxide (SO₂) remain almost unchanged from the previous week, but the APIs for nitrogen oxide (NOx) and total suspended (悬浮) particles (TSP) rose by 35 and 27 percent. The overall quality still belonged to class 2 category. Nitrogen oxide, caused mainly by vehicle exhaust and burning of cooking gas, was still the major pollutant of the week.

The Shanghai Environmental Monitoring Centre operates six automatic air monitors in the city’s Putuo, Yangpu, Luwan, Hongkou, Jing’an and Xuhui districts.

China’s government has been trying all measures to reduce pollution in the past few years. Now people can enjoy a fresh environment everywhere. The following two graphs are adopted from the column of “City Information” on the webpage of Beijing Review.
Graph 1: Olympic Cities Air Quality Report

City	Date	API	Major Pollutant	Air Quality Degree	Quality Condition
Beijing	Sep. 8	37	N/A	Ⅰ	Very good
Qinhuangdao	Sep. 8	52	PM10	Ⅱ	Good
Qingdao	Sep. 8	68	PM10	Ⅱ	Good
Shanghai	Sep. 8	67	PM10	Ⅱ	Good
Shenyang	Sep. 8	88	PM10	Ⅱ	Good
Tianjin	Sep. 8	54	PM10	Ⅱ	Good

Graph 2: Chinese National Standard

API Values	Levels of health concern	Colors
When the API is in this range:	...air quality conditions are:	...as symbolized by this color:
0 to 50	Very good	Blue
51 to 100	Good	Green
101 to 150	Slight pollution	Yellow
151 to 200	Moderate pollution	Orange
201 to 250	Medium pollution	Red
251 to 300	High pollution	Purple
301 to 500	Hazardous	Brown

Notes:
**API stands for Air Pollution Index(指数).
**Particulate matter (PM10) is a major component of air pollution that threatens both our health and our environment. It consists of very small liquid and solid particles floating in the air.
**Sulfur dioxide(SO2) acts as an acid．Inhalation(吸入) results in labored breathing, coughing, or a sore throat and may cause permanent lung damage.

Eating too much fatty food, exercising too little and smoking can raise your future risk of heart disease. But there is another factor that can cause your heart problems more immediately: the air you breathe.
Previous studies have linked high exposure (暴露）to environmental pollution to an increased risk of heart problem, but two analyses now show that poor air quality can lead to heart attack or stroke (中风）within as little as a few hours after exposure. In one review of the research, scientists found that people exposed to high levels of pollutants (污染物）were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. A separate study of stroke patients showed that even air that the U. S. Environmental Protection Agency (EPA) considers to be of “moderate” (良好）quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure.
The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.
【小题1】The text mainly discusses the relationship between .

A．heart problems and air quality

B．heart problems and exercising

C．heart problems and smoking

D．heart problems and fatty food
