In theory, any detectable level of lead in paint can present a potential of exposure when paint coatings are damaged and/or are disturbed through construction activities. The extent and level of this exposure is commonly determined by the route and site of exposure, duration and frequency of exposure and, concentration or dose. Because there are so many factors that influence the toxicity of lead in the human body, any exposures to lead should be avoided or at a minimum, should be minimized. This is especially true for children. The most susceptible population are young children, particularly toddlers and infants.
