Chemical Classification: Inorganic substancesSummary: Manganese is a naturally occurring metal that is found in many types of rocks. Pure manganese is silver-colored, but does not occur naturally. It combines with other substances such as oxygen, sulfur, or chlorine. Manganese can also be combined with carbon to make organic manganese compounds. Common organic manganese compounds include pesticides, such as maneb or mancozeb, and methylcyclopentadienyl manganese tricarbonyl (MMT), a fuel additive in some gasolines. Manganese is an essential trace element and is necessary for good health. Manganese can be found in several food items, including grains and cereals, and is found in high amounts in other foods, such as tea.

Summary about a hazardous substance taken from Chapter One of its respective ATSDR Toxicological Profile.
Isla de Vieques is part of the Commonwealth of Puerto Rico, located about 7 miles east-southeast of the main island of Puerto Rico. Until May 2003, the U.S. Navy owned approximately half of the island and conducted military exercises that included live bombing. The live bombing exercises were conducted until April 1999 in a 900-acre area known as the Live Impact Area. The Navy conducted exercises with practice bombs from May 2000 to May 2003.
On May 22, 2000, United States Senator Mike DeWine (Ohio) petitioned the Agency for Toxic Substances and Disease Registry (ATSDR) to determine whether air pollution was affecting the health of Marietta, Washington County, Ohio residents.
ATSDR and Texas Department of State Health Services (DSHS) are conducting an extensive review of environmental health concerns raised by the community members in Midlothian, Texas to determine if chemical releases from local industries could or have affected the health of persons and animals in the area.
Toxicological and Health Professionals
Succinctly characterizes the toxicologic and adverse health effects information for a hazardous substance.
Quick reference guide providing information such as chemical and physical properties, sources of exposure, routes of exposure, minimal risk levels, children's health, and health effects for a substance.
Prioritization of substances based on a combination of their frequency, toxicity, and potential for human exposure at National Priorities List (NPL) sites.
The MRL is an estimate of the daily human exposure to a hazardous substance that is likely to be without appreciable risk of adverse, non-cancer health effects over a specified duration of exposure. The information in this MRL serves as a screening tool to help public health professionals decide where to look more closely to evaluate possible risk of adverse health effects from human exposure.
