Gyimi river [1] also known as Jimi River [2] is a stream in Ashanti Region, Ghana. It forms in area of a Naimakrom settlement. [3] It confluence with Ofin River is near town Dunkwa-on-Offin.
Word gyimi in the Twi language of the Akan people [4] can be roughly translated as foolery or not normal. [5]
Within the Gyimi (Jimi) river basin heavy metal contamination is present. It is caused by mining operations. [6] [7]
Ghana is a West African country in Africa, along the Gulf of Guinea.
A toxic heavy metal is any relatively dense metal or metalloid that is noted for its potential toxicity, especially in environmental contexts. The term has particular application to cadmium, mercury and lead, all of which appear in the World Health Organization's list of 10 chemicals of major public concern. Other examples include manganese, chromium, cobalt, nickel, copper, zinc, silver, antimony and thallium.
The Akosombo Dam, also known as the Volta Dam, is a hydroelectric dam on the Volta River in southeastern Ghana in the Akosombo gorge and part of the Volta River Authority. The construction of the dam flooded part of the Volta River Basin and led to the subsequent creation of Lake Volta. Lake Volta is the largest man-made lake in the world by surface area. It covers 8,502 square kilometres (3,283 sq mi), which is 3.6% of Ghana's land area. With a volume of 148 cubic kilometers, Lake Volta is the world's third largest man-made lake by volume; the largest being Lake Kariba which contains 185 cubic kilometers of water.
The Gunnison River is located in western Colorado, United States and is one of the largest tributaries of the Colorado River.
The Selenga or Selenge is a major river in Mongolia and Buryatia, Russia. Originating from its headwater tributaries, the Ider and the Delger mörön, it flows for 992–1,024 kilometres (616–636 mi) before draining into Lake Baikal. The Selenga therefore makes up the most distant headwaters of the Yenisey-Angara river system.
The Carson River is a northwestern Nevada river that empties into the Carson Sink, an endorheic basin. The main stem of the river is 131 miles (211 km) long although the addition of the East Fork makes the total length 205 miles (330 km), traversing five counties: Alpine County in California and Douglas, Storey, Lyon, and Churchill Counties in Nevada, as well as the Consolidated Municipality of Carson City, Nevada. The river is named for Kit Carson, who guided John C. Frémont's expedition westward up the Carson Valley and across Carson Pass in winter, 1844. The river made the National Priorities List (NPL) on October 30, 1990 as the Carson River Mercury Superfund site (CRMS) due to investigations that showed trace amounts of mercury in the wildlife and watershed sediments.
The Río Tinto is a river in southwestern Spain that rises in the Sierra Morena mountains of Andalusia. It flows generally south-southwest, reaching the Gulf of Cádiz at Huelva. The Rio Tinto river has a unique red and orange colour derived from its chemical makeup that is extremely acidic and with very high levels of iron and heavy metals.
Soil contamination, soil pollution, or land pollution as a part of land degradation is caused by the presence of xenobiotic (human-made) chemicals or other alteration in the natural soil environment. It is typically caused by industrial activity, agricultural chemicals or improper disposal of waste. The most common chemicals involved are petroleum hydrocarbons, polynuclear aromatic hydrocarbons, solvents, pesticides, lead, and other heavy metals. Contamination is correlated with the degree of industrialization and intensity of chemical substance. The concern over soil contamination stems primarily from health risks, from direct contact with the contaminated soil, vapour from the contaminants, or from secondary contamination of water supplies within and underlying the soil. Mapping of contaminated soil sites and the resulting cleanups are time-consuming and expensive tasks, and require expertise in geology, hydrology, chemistry, computer modeling, and GIS in Environmental Contamination, as well as an appreciation of the history of industrial chemistry.
Burke Canyon is the canyon of the Burke-Canyon Creek, which runs through the northernmost part of Shoshone County, Idaho, U.S., within the northeastern Silver Valley. A hotbed for mining in the late-nineteenth and twentieth centuries, Burke Canyon now contains several ghost towns and remnants of former communities along Idaho State Highway 4, which runs northeast through the narrow canyon to the Montana border.
The Mining industry of Ghana accounts for 5% of the country's GDP and minerals make up 37% of total exports, of which gold contributes over 90% of the total mineral exports. Thus, the main focus of Ghana's mining and minerals development industry remains focused on gold. Ghana is Africa's largest gold producer, producing 80.5 t in 2008. Ghana is also a major producer of bauxite, manganese and diamonds. Ghana has 20 large-scale mining companies producing gold, diamonds, bauxite and manganese, and, there are also over 300 registered small scale mining groups and 90 mine support service companies.
The Birim River is one of the main tributaries of the Pra River in Ghana and the country's most important diamond-producing area, flowing through most of the width of the Eastern region. The river rises in the east of the Atewa Range, flows north through the gap between this range and the Kwahu Plateau, then runs roughly south-west until it joins the Pra. It gives its name to the Birimian rock formation, which yields most of the gold in the region. Ghana is the second largest producer of gold in Africa.
Environmental effects of mining can occur at local, regional, and global scales through direct and indirect mining practices. The effects can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes. These processes also affect the atmosphere from the emissions of carbon which have an effect on the quality of human health and biodiversity. Some mining methods may have such significant environmental and public health effects that mining companies in some countries are required to follow strict environmental and rehabilitation codes to ensure that the mined area returns to its original state.
The Obuasi Gold Mine is an underground gold mine situated near Obuasi, in the Ashanti Region of Ghana. It was at one time one of the world's ten largest gold mines. The mine is in Obuasi Municipal District, 60 kilometres (37 mi) southwest of the regional capital Kumasi.
Akrofuom is a town on Gyimi River in the Ashanti Region of Ghana. It is the capital of the Akrofuom District. The town is known for the Akrofuom Senior High Technical School. The school is a second cycle institution.
Bogoso is a mining town and is the capital of Prestea-Huni Valley district, a district in the Western Region of Ghana.
Zinc mining is the process by which mineral forms of the metal zinc are extracted from the earth through mining. A zinc mine is a mine that produces zinc minerals in ore as its primary product. Common co-products in zinc ores include minerals of lead and silver. Other mines may produce zinc minerals as a by-product of the production of ores containing more valuable minerals or metals, such as gold, silver or copper. Mined ore is processed, usually on site, to produce one or more metal-rich concentrates, then transported to a zinc smelter for production of zinc metal.
Bangladesh, with an area of 147,570 km2, features a flood plain landscape and several river systems throughout the country. This landscape provides the major natural resources of water, land, fisheries, forests, and wildlife. The country currently faces several environmental issues which threaten these resources, including groundwater metal contamination, increased groundwater salinity, cyclones and flooding, and sedimentation and changing patterns of stream flow due to watershed mismanagement. Some of these, such as the changing patterns of stream flow and presence of lead in groundwater, can be directly correlated with human activity and industrial processes, while others, such as cyclones and flooding are naturally occurring issues. Many of these issues are further exacerbated by climate change, which causes increased occurrence of storms and cyclones and rising sea levels. According to the Notre Dame Global Adaptation Index, Bangladesh is the 43rd most vulnerable country to the effects of climate change, and the 37th least prepared country to address these effects. There has been some government actions taken to address these issues.
The geology of Ghana is primarily very ancient crystalline basement rock, volcanic belts and sedimentary basins, affected by periods of igneous activity and two major orogeny mountain building events. Aside from modern sediments and some rocks formed within the past 541 million years of the Phanerozoic Eon, along the coast, many of the rocks in Ghana formed close to one billion years ago or older leading to five different types of gold deposit formation, which gave the region its former name Gold Coast.
Laos is a nation with plentiful surface water and broad rivers, but outside of cities there is little infrastructure to make that water clean and accessible. Very little improvement has been made since the end of the Laotian Civil War in 1975, especially compared to peer nations such as Thailand. By 2015, 76% of Laotians nationwide were estimated to have access to “improved” water, while 71% were estimated to have access to “improved” sanitation.
The Kubi gold mine is an abandoned open pit mine located 8 kilometres (5.0 mi) northeast of Dunkwa-on-Offin and 22 kilometres (14 mi) south of Obuasi, in Central Region, southern Ghana. It is 180 kilometres (110 mi) northwest of the national capital, Accra.
