Nationally, 13 million children, or 65 percent of U.S. kids, spend some part of the afternoon in child care and at California alone, roughly 1.1 million children five decades or younger attend child care. In this exact same condition, many adults might also be subjected as roughly 146,000 employees work 40 hours or more a week child care centers. Child care environments include substances which may be harmful for kids. Recent studies suggest that lots of child care environments might contain pesticides, allergens, volatile organic compounds from cleaning agents and sanitizers, and other contaminants which may be toxic to children's wellbeing.
