Harm of residual scale in kettle

This shows that even if the drinking water meets the health standards, the trace metal elements can be deposited and accumulated in the water after being stored in a warm water bottle, which is harmful to human health. If the drinking water does not meet the health standards, the potential health hazards are more serious. Regular drinking will cause diseases of digestive, nervous, urinary, hematopoietic, circulatory and other systems and cause aging, which is due to the scale containing more harmful metal elements such as cadmium, mercury, arsenic, aluminum and so on.
