What are the example for enviornmental impact assesment?

What is the impact to health of being in a room full of people smoking cigarettes?  What can you do to reduce the impact?

• What is the impact to your health of being in a bar full of people smoking cigarettes for one day, one week, one month, or one year? What can you do to reduce the impact? Example is traveling for multiple months including in cities that have not banned smoking in bars.

• Answer:

  Well being exposed consistently to secondhand smoke certainly will do your health no favors, that's for sure. Secondhand smoke has been linked to lung cancers and other respiratory problems. I know a bartender who gets his lungs checked every year because of the smoke he breathes at work. Depending on the laws in the state you are in, bars that are in restaurants may be smoke free, so if that is the case, go to restaurants that have a bar area instead of a standalone bar. Bonus: you'll be able to eat, too. Try sitting as far away as you can from smokers. It will help a little, especially if the bar has some kind of air filter. Even if the bar is crowded, you might be able to find an oasis where there aren't any smokers close to you. Avoid really crowded bars where it would be difficult to put distance between you and smokers. Try hotel bars as opposed to the neighborhood bar-they probably won't be as crowded, and some may ban smoking. Try looking for smoke free bars in the state you are in. There might be a few, but it seems that smoking and drinking seem to go together, so the odds of finding a bar that doesn't serve food in an state that allows smoking probably aren't that great. But it might be worth it to try to find one. I've seen people carry portable fans and place them where they are sitting so that the smoke blows back toward the offending person, but that seems to be kind of, well, out there. But, if you don't care, you might try that, I suppose.
