Rézszivárgás

Rézszivárgás is a Hungarian term that translates to "copper leakage" in English. It refers to the undesirable migration of copper from plumbing pipes into drinking water. Copper pipes have been widely used in plumbing systems for their durability and resistance to corrosion. However, under certain water conditions, copper can dissolve into the water, leading to elevated levels.

Factors that can contribute to rézszivárgás include water acidity (low pH), high water temperature, and the absence of protective mineral scales on the interior of the pipes. Soft water, which typically has a lower mineral content, is more likely to leach copper than hard water. Stagnant water in pipes, such as overnight or after a period of disuse, can also increase copper concentrations as it has more time to interact with the pipe material.

While copper is an essential trace element for human health, excessive intake can cause adverse effects. Symptoms of copper toxicity can include gastrointestinal upset, such as nausea, vomiting, and diarrhea. In more severe cases or with chronic exposure, liver and kidney damage may occur. Regulatory bodies, such as the World Health Organization and national environmental agencies, set maximum permissible levels for copper in drinking water to protect public health.

To mitigate rézszivárgás, homeowners can flush their taps for a short period before using the water for drinking or cooking, especially after periods of stagnation. Water testing can determine copper levels and identify potential issues. In some cases, adjusting water pH or installing water treatment systems may be recommended if high copper levels persist.
