     Apparently, we are safe neither at home nor in the business office. We use water in both places, but the
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 seemingly harmless activities
as cleaning one's house. They are released (set free) from water by daily actions like water running out of tap,
spraying from garden pipes, or splashing in dishwashers and washing machines. As the water is moving, these
chemicals are released into the air and then breathed in. Once inside our bodies, they start to affect our health.
     Does this mean we should stop bathing? No, say the scientists, but we should put all pollution into
perspective. Activities at home such as the burning of coal, cooking oil, or even candles release carbon
monoxide and particulates such as cigarette ashes which have been proven as harmful to health as working or
living near heavy traffic. New rugs, bedding, and even clothing give off that "new smell," which is a sure sign
of chemicals. In the office, newly applied paint, newly purchased telephones and other telecommunications
equipment, and computers release polluting chemicals, too. As offices and homes often have inadequate
ventilation (通风), these chemicals can build up to become health problems. Their poisonous effects are only
now being slowly recognized.
     These facts suggest that, at a minimum, proper airing of newly purchased goods with an obvious chemical
smell is a wise warning. Home and office windows should be opened during good weather. Evenone's car
needs to be ventilated as well while in the garage.
     We need further research to understand better other potential health dangers, too. For example, the effects
of overcrowding of schools (carbon dioxide build-up), the factory work environment (an endless list of
potentially dangerous substances), and even home heating and cooling (the air conditioner may be our enemies,
not our friends) have only recently started to come to light. Until we understand the effects of our new
technological environment better, we can only hope that "there is no place like home."
