What health issues can result from short-term exposure to copper in drinking water?

Short-term exposure to copper in drinking water can lead to stomach and intestinal distress. When ingested in significant quantities, copper can irritate the gastrointestinal tract, resulting in symptoms such as nausea, vomiting, abdominal cramps, and diarrhea. This is particularly concerning for vulnerable populations, including children, who may be more susceptible to these immediate adverse effects.

While other health issues associated with copper exposure exist, they are typically associated with long-term exposure or occur at higher concentrations than what is usually considered short-term exposure in drinking water. Liver and kidney damage, anemia, respiratory problems, and neurological disorders are more often linked to chronic exposure or higher doses of copper. Hence, for short-term exposure specifically, gastrointestinal symptoms are the most direct and recognized health impacts.
