Chapter 2, Problem 34Q
Here are air quality data for the last week of 2015, in Beijing, China, for air quality based on the primary pollutant of PM2.5.
- a. In general, which groups of people are the most sensitive to particulate matter?
- b. The U.S. Environmental Protection Agency determined that air rated between 51–100 is acceptable except for particularly sensitive groups. For the data shown, when was the air acceptable or better?
- c. The levels of PM do not necessarily drop off at night the way they do for ozone. Explain.
- d. The levels of particulate matter can increase sharply. Propose two different reasons that could account for this observation.

Ll.125.
Suppose you have an 8-hour ozone value of 0.088 ppm, and a PM2.5 value of 35.7 ug/m3. The AQI value is Blank 1 and the
responsible pollutant is Blank 2. According to the AQI scale, this falls under the category Blank 3.
Note: for the pollutant, choose between ozone and PM2.5

- Marie Curie was born in Poland but studied and carried out her research in Paris. In 1903, she shared the Nobel Prize in Physics with H. Becquerel and her husband Pierre for their discovery of radioactivity. (In 1911 she received the Nobel Prize in Chemistry for the discovery of two new chemical elements, radium and polonium, the latter named for her homeland, Poland.) They and others observed that a radioactive substance could emit three types of radiation: alpha (), beta (), and gamma (). If the radiation from a radioactive source is passed between electrically charged plates, some particles are attached to the positive plate, some to the negative plate, and others feel no attraction. Which particles are positively charged, which are negatively charged, and which have no charge? Of the two charged particles, which has the most mass? Radioactivity. Alpha (), beta I(), and gamma () rays from a radioactive element are separated by passing them between electrically charged plates.arrow_forwardLl.167.arrow_forwardWhat is Environmental chemistry?
