As the weather gets warmer, we like to open our windows to let in the fresh air. Problem is, that air is not as fresh as you think. What you may not realize is if you live in a house constructed before 1978, simply opening a window could result in the release of toxic lead dust. Where does the dust come from? Paint that’s cracking. And the simple act of opening or closing the window grinds the paint (we’re talking about lead-based paint that was prevalent pre-1978) into powder, thus releasing lead dust in and around the window.
How is this.
