                　 自来水出厂时，是卫生达标的饮用水。出厂后各种原因导致的污染，称为二次污染。<br>
                <br>
                1、自来水的污染<br>
                <br>
                1）管道污染：由于管道的老化、生锈、渗漏、腐蚀<br>
                <br>
                2）水箱污染：露天、不定期消毒，不定期检查<br>
                <br>
                2、桶装水的污染<br>
                <br>
                1）桶装水的久放，而导致细菌滋生。<br>
                <br>
                2）水桶和饮水机导致污染<br>
                <br>
                3）水杯导致污染<br>

                <br>
                进食与饮水并驾齐驱<br>
                <br>
                重视进食，却忽视饮水是不少家长存在的一大喂养误区。<br>
                <br>
                水是构成人体组织细胞和体液的重要成分，一切生理与代谢活动，包括食物的消化、养分的运送、吸收到废物的排泄，无一能<br>
                <br>
                离开水。<br>
                <br>
                年龄越小，对水的需求相对越多。<br>
                <br>
                因此在每餐之间，应给孩子一定量的水喝。<br>
                <br>
                注意不要给孩子茶水、咖啡、可乐等，而以纯净水、矿泉水为宜。<br>
