The Origin of Lead
The first is the arbitrary discharge of industrial pollutants and wastewater (mainly in industries such as exercise, mining, chemical, printing and dyeing) and the widespread use of pesticides and insecticides in agricultural production, resulting in severe water pollution.
The second and most important origin is the release of lead caused by corrosion in the township water supply network, which is also the main cause of damage to human health caused by lead in drinking water.
Most of the water pipes currently used in our country are metal pipes containing lead. Due to the use of chlorine as a disinfectant in water, the residual chlorine in the water accelerates the corrosion and aging of lead containing pipes. Generally, when water pipes that have exceeded their service life for more than 5 years are used, the amount of lead released will be increased, and the concentration of lead in water will also increase.

The third origin is that low-quality faucets and various substandard pipes used in households can be separated from lead. This point is simply overlooked by people.

Therefore, even if the tap water can meet the national standard when it leaves the factory, the lead content in the water may exceed this standard when it reaches the user's tap water after a long pipeline network.
1. When the tap water is out of use for more than 6 hours, be sure to turn on the faucet and flush it for two to three minutes before use, as the lead content in the water in the pipeline is very high at this time.
2. Many households now have hot water supply, but it is best not to use it as drinking water or cooking water, as the lead content in hot water is many times higher than that in cold water.
3. It is necessary to use qualified lead-free faucets. Try to choose high-quality and qualified pipes when decorating your home.
4. Families with conditions should choose to install household water purifiers (reverse osmosis technology), whose multi-stage filtration function can effectively remove lead and ensure the safety of your drinking water.
Lead is trace in drinking water, but long-term consumption of water containing lead accumulates in the human body and is not easily excreted, causing serious health damage.
