Subaé River
The Subaé River () is a river in Bahia state of Brazil. It has its source in the city of Feira de Santana and runs to the mouth at the Baía de Todos os Santos. The river was used by the Portuguese to create a large-scale sugarcane production in the Recôncavo region. The city of Santo Amaro was built on terraced land above the river. It has a single tributary, the Serjimirim River. Pollution The Subaé River is polluted along much of its course, notably by lead, zinc, and cadmium Cadmium is a chemical element with the symbol Cd and atomic number 48. This soft, silvery-white metal is chemically similar to the two other stable metals in group 12, zinc and mercury. Like zinc, it demonstrates oxidation state +2 in most of .... Lead pollution originated in industrial sewage of a processing facility owned by the Companhia Brasileira de Chumbo, now defunct.

Baía De Todos Os Santos
The Bay of All Saints ( pt, Baía de Todos os Santos), also known as All Saints' Bay and Todos os Santos Bay, is the principal bay of the Brazilian state of Bahia, to which it gave its name. It sits on the eastern coast of Brazil, surrounding part of Bahia's capital Salvador and opening to the Atlantic Ocean. It covers , making it the largest bay in Brazil. Farol da Barra (Barra Lighthouse), on the site of a historic fort, stands at the entrance of the bay. The Bay of All Saints is shallow along much of its area with an average depth of . The Paraguaçu River travels to empty into the bay and the coastal lowlands of the Reconcavo Basin are at its mouth. It contains 91 islands, the largest being Itaparica Island at its entrance. Other important islands include the Ilha dos Frades, ilha de Maré, ilha de Bom Jesus, and the small Ilha do Medo.

Bahia
Bahia ( , , ; meaning "bay") is one of the 26 Federative units of Brazil, states of Brazil, located in the Northeast Region, Brazil, Northeast Region of the country. It is the fourth-largest Brazilian state by population (after São Paulo (state), São Paulo, Minas Gerais, and Rio de Janeiro (state), Rio de Janeiro) and the 5th-largest by area. Bahia's capital is the city of Salvador, Bahia, Salvador (formerly known as "Cidade do São Salvador da Bahia de Todos os Santos", literally "City of the Saint Savior of the Bay of All the Saints"), on a Spit (landform), spit of land separating the Bay of All Saints from the Atlantic. Once a monarchial stronghold dominated by Agriculture in Brazil, agricultural, Slavery in Brazil, slaving, and ranching interests, Bahia is now a predominantly Working class, working-class industrial and agricultural state. The state is home to 7% of the Brazilian population and produces 4.2% of the country's GDP. Name The name of the state derives from the ...

Santo Amaro, Bahia
Santo Amaro, also known as Santo Amaro da Purificação (), is a Municipalities of Brazil, municipality in the state of Bahia in Brazil. The population is 60,131 (2020 est.) in an area of . It is located in the metropolitan area of Salvador. Santo Amaro is located approximately from the city of Salvador, Bahia, Salvador.

Lead
Lead is a chemical element with the symbol Pb (from the Latin ) and atomic number 82. It is a heavy metal that is denser than most common materials. Lead is soft and malleable, and also has a relatively low melting point. When freshly cut, lead is a shiny gray with a hint of blue. It tarnishes to a dull gray color when exposed to air. Lead has the highest atomic number of any stable element and three of its isotopes are endpoints of major nuclear decay chains of heavier elements. Lead is toxic, even in small amounts, especially to children. Lead is a relatively unreactive post-transition metal. Its weak metallic character is illustrated by its amphoteric nature; lead and lead oxides react with acids and bases, and it tends to form covalent bonds. Compounds of lead are usually found in the +2 oxidation state rather than the +4 state common with lighter members of the carbon group. Exceptions are mostly limited to organolead compounds. Like the lighter members of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zinc
Zinc is a chemical element with the symbol Zn and atomic number 30. Zinc is a slightly brittle metal at room temperature and has a shiny-greyish appearance when oxidation is removed. It is the first element in group 12 (IIB) of the periodic table. In some respects, zinc is chemically similar to magnesium: both elements exhibit only one normal oxidation state (+2), and the Zn2+ and Mg2+ ions are of similar size.The elements are from different metal groups. See periodic table. Zinc is the 24th most abundant element in Earth's crust and has five stable isotopes. The most common zinc ore is sphalerite (zinc blende), a zinc sulfide mineral. The largest workable lodes are in Australia, Asia, and the United States. Zinc is refined by froth flotation of the ore, roasting, and final extraction using electricity ( electrowinning). Zinc is an essential trace element for humans, animals, plants and for microorganisms and is necessary for prenatal and postnatal development. It ...

Cadmium
Cadmium is a chemical element with the symbol Cd and atomic number 48. This soft, silvery-white metal is chemically similar to the two other stable metals in group 12, zinc and mercury. Like zinc, it demonstrates oxidation state +2 in most of its compounds, and like mercury, it has a lower melting point than the transition metals in groups 3 through 11. Cadmium and its congeners in group 12 are often not considered transition metals, in that they do not have partly filled ''d'' or ''f'' electron shells in the elemental or common oxidation states. The average concentration of cadmium in Earth's crust is between 0.1 and 0.5 parts per million (ppm). It was discovered in 1817 simultaneously by Stromeyer and Hermann, both in Germany, as an impurity in zinc carbonate. Cadmium occurs as a minor component in most zinc ores and is a byproduct of zinc production. Cadmium was used for a long time as a corrosion-resistant plating on steel, and cadmium compounds are used as red, orang ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
