Generally, the long term effects are not that evident, but some VOC's are more carcinogens according to US environmental protection agency. Although, many paint companies claim that their paints are VOC free which is actually false. It might be true that the VOC is not present in the base of the paint, but when the pigment is added to the paint the VOC increases. Hence, carpeting, furniture, cook stoves and VOC's from paints are really harmful indoor pollutants.
