What is Manganese:
Surface and ground waters rarely contain more than 1 mg/L of soluble or suspended manganese. Manganese can act as an oxidizing or reducing agent depending on its valence state. Increased levels of Manganese will cause a black to brown color to the water that will stain laundry and porcelain surfaces. It will also cause a bitter, metallic taste.
Manganese Exposure and Health Risks:
Because Manganese plays a vital role in maintaining normal physiological function, low-level exposure is essential. However, long term exposure or exposure to high levels of manganese can be toxic. Toxicity is marked by severe psychiatric symptoms, irritability, anxiety, hallucinations, and violent outbursts. Other symptoms include insomnia, confusion, dry throat, chest tightness, flu-like fever, vomiting, and kidney damage. Chronic exposure can lead to chronic neurological disorders, headaches, muscle weakness, speech disturbance, and impairment to reaction time, hand-eye coordination, and hand steadiness. Direct contact with manganese can cause serious eye damage and skin irritation. Manganese exposure can occur through contact, inhalation, and ingestion.

Measuring Manganese:
Dissolved Manganese concentration in water can be measured in units of parts per million (ppm). We carry kits from CHEMetrics that determine Manganese levels in water, ranging from 0-2 ppm and 0-60 ppm. All of our Manganese products can be viewed HERE.
