An electric heater rated at 1000 watts (1 kilowatt), operating for one hour uses one kilowatt-hour (equivalent to 3.6 megajoules) of energy. A television rated at 100 watts operating for 10 hours continuously uses one kilowatt-hour. A 40-watt light bulb operating continuously for 25 hours uses one kilowatt-hour.
Ozone is a gas that occurs both in the Earth's upper atmosphere and at ground level. Ozone can be good or bad for your health and the environment, depending on its location in the atmosphere.

A mixture of the small PM2.5 particles get directly into our bloodstream by sneaking through the tiniest air sacs called alveoli. Once in your blood stream, these air pollution particles act like cigarette smoke, triggering inflammation that makes cholesterol more sticky.
