【简答题】
Apparently, we are safe neither at home nor in the business office. We use water in both places, but the above-mentioned research shows that chemicals added to our local water supply to kill harmful bacteria can have unwanted side effects. These chemicals can cause potential harm through drinking and in such seemingly harmless activities as cleaning one’s house. These additives are released from water by daily actions like water running out of faucets, spraying from garden hoses, or splashing in dishwashers and washing machines. As the water is agitated, these chemicals are released into the air and then breathed in. Once inside our bodies, they start to affect our health adversely.
