These health effects include behavioral changes and other nervous system effects, which include movements that may become slow and clumsy. Inhalation: The most common health problems in workers exposed to high levels of manganese involve the nervous system. Manganese is an essential nutrient, and eating a small amount of it each day is important to stay healthy. This section looks at studies concerning potential health effects in human and animal studies. People who smoke tobacco or inhale second-hand smoke are typically exposed to manganese at levels higher than those not exposed to tobacco smoke. Lifestyle traits may also lead to exposure to manganese. industries using or manufacturing products containing manganese,.Releases of manganese into the air occur from: Drinking water containing manganese or swimming or bathing in water containing manganese may expose you to low levels of this chemical.Īir also contains low levels of manganese, and breathing air may expose you to it. Manganese is routinely contained in groundwater, drinking water and soil at low levels. Vegetarians who consume foods rich in manganese such as grains, beans and nuts, as well as heavy tea drinkers, may have a higher intake of manganese than the average person.Ĭertain occupations like welding or working in a factory where steel is made may increase your chances of being exposed to high levels of manganese.īecause manganese is a natural component of the environment, you are always exposed to low levels of it in water, air, soil, and food. The primary way you can be exposed to manganese is by eating food or manganese-containing nutritional supplements. Small amounts of manganese are used in a pharmaceutical product called mangafodipir trisodium (MnDPDP) to improve lesion detection in magnetic resonance imaging of body organs. It may also be used as an additive in gasoline to improve the octane rating of the gas. Manganese is also used in a wide variety of other products, including: It is used in carbon steel, stainless steel, high-temperature steel, and tool steel, along with cast iron and superalloys.Ĭonsumer products: Manganese occurs naturally in most foods and may be added to food or made available in nutritional supplements. Manufacturing: Manganese is used principally in steel production to improve hardness, stiffness, and strength. Manganese is a trace element and is necessary for good health. Rather, it occurs combined with other substances such as oxygen, sulfur, and chlorine. Pure manganese is a silver-colored metal however, it does not occur in the environment as a pure metal. Manganese is a naturally occurring substance found in many types of rocks and soil. You must also consider any other chemicals you are exposed to and your age, sex, diet, family traits, lifestyle, and state of health. These factors include the dose (how much), the duration (how long), and how you come in contact with it. If you are exposed to manganese, many factors will determine whether you will be harmed. You may be exposed by breathing, eating, or drinking the substance, or by skin contact. You can be exposed to a substance only when you come in contact with it. Such a release does not always lead to exposure. When a substance is released either from a large area, such as an industrial plant, or from a container, such as a drum or bottle, it enters the environment. This information is important because these sites may be sources of exposure and exposure to this substance may harm you. Although the total number of NPL sites evaluated for this substance is not known, the possibility exists that the number of sites at which manganese is found may increase in the future as more sites are evaluated. Manganese has been found in at least 869 of the 1,699 current or former NPL sites. ![]() ![]() These sites are then placed on the National Priorities List (NPL) and are targeted for long-term federal clean-up activities. The Environmental Protection Agency (EPA) identifies the most serious hazardous waste sites in the nation. This public health statement tells you about manganese and the effects of exposure to it. For more information, call the ATSDR Information Center at 1-80. The effects of exposure to any hazardous substance depend on the dose, the duration, how you are exposed, personal traits and habits, and whether other chemicals are present. This information is important because this substance may harm you. Health Statements about hazardous substances and their healthĮffects.
