Industrial workers who are exposed to manganese dust may develop nervous system problems similar to Parkinson's disease. Symptoms of manganese toxicity do not usually appear even at high levels of dietary intake; however, in severe cases of excessive manganese consumption, humans can develop a syndrome called "manganese madness," characterized by hallucinations, violent acts, and irritability. Over-consumption of manganese is also associated with impotence. Manganese toxicity is most likely to occur in people with chronic liver disease, because your liver plays an important role in eliminating excess manganese from your body.

Bean plants doesn't grow well when the soil is too acidic. That is, because of aluminum toxicity or manganese toxicity. Aluminum is not an essential element for plants but too much can harm plants. Too much aluminum reduces the growth of the root. Manganese toxicity is when the plant takes up too much manganese in plants, which limits the uptake of other important, essential minerals the plant needs. It affects the metabolic processes and leads to sterility. A few signs are chlorosis of younger leaves and brown or yellow spots on the leaf. Also, to mention, soil with a pH lower than 5.8 has a greater chance of having diseases.
