When Oakland High School in California moved into a new building, the students and teachers noticed a strong smell. Then almost half of the students began to have a headache and a cough. Experts (专家) came to find the cause of the sickness. Finally, they discovered that the air in the building was not safe to breathe. They were surprised to find out that the desks and chairs in the school library caused the trouble. These desks and chairs were made of particleboards(合成板). This kind of board is cheap. It is made of very small pieces of wood held together with a chemical (化学物质). This is just one example of a modern problem that is most common in cities—indoor air pollution(污染).
