引领。 & 你的饮用水
饮用水中的铅, 虽然很少是铅中毒的唯一原因, can significantly increase a person's total lead exposure, particularly the exposure to infants who drink baby formulas and concentrated juices that are mixed with water. EPA estimates that drinking water can make up 20% or more of a person's total exposure to lead.
引领。 is unusual among drinking water contaminants in that it seldom occurs naturally in water supplies like rivers and lakes. 引领。 enters drinking water primarily as a result of the corrosion, 或者磨损, of materials containing lead in the water distribution system and household plumbing. These materials include lead-based solder used to join copper pipe, 黄铜和镀铬黄铜水龙头, 在某些情况下, pipes made of lead that connect your house to the water main, 也被称为服务线. In 1986, Congress banned the use of 铅焊料 containing greater than 0.2% lead, and restricted the lead content of faucets, pipes and other plumbing materials to 8.0%.
