Cerrón Grande Reservoir
The Cerrón Grande Reservoir (Spanish: ), also known locally as Lake Suchitlán (Spanish: ), is a reservoir in northern El Salvador and the largest body of fresh water in the country. The reservoir was filled between 1973 and 1976, subsequent to the construction of the Cerrón Grande Hydroelectric Dam. The Cerrón Grande Reservoir is among the most polluted bodies of fresh water in Central America. Name The reservoir is called Cerrón Grande after the hydroelectric dam that formed it, which itself was named after the property it was built on. The reservoir is known locally as Lake Suchitlán (''Lago Suchitlán''). Suchitlán is a Nahuatl word meaning "Place of Flowers" and was coined by Salvadoran writer Alejandro Coto. Geography The Cerrón Grande Reservoir is located in northern El Salvador and surrounded by the departments of Cabañas, Chalatenango, Cuscatlán, and San Salvador. The reservoir's primary inflows are the Acelhuate River and the Lempa River. Its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Suchitoto
Suchitoto is a municipality in the Department of Cuscatlán, El Salvador that has seen continuous human habitation long before Spanish colonization. Within its municipal territory, Suchitoto holds the site of the original founding of the Villa of San Salvador in 1528 that existed for a short time before the site was abandoned. In more recent times, the municipality has prospered even after the severe effects of civil war in El Salvador that lasted between 1980 - 1992 and saw the population of Suchitoto decrease from 34,101 people in 1971 to 13,850 by 1992. It has become an important tourist destination partly due to its well conserved colonial architecture and cobblestone roads that provide a sense of Spanish colonial living. This rise in tourism has attracted service sector businesses to open up in the small city including hostels, restaurants, and picturesque cafes. As a result of tourism, many arts and cultural spaces have opened up in Suchitoto that are also providing positiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dieldrin
Dieldrin is an organochloride originally produced in 1948 by J. Hyman & Co, Denver, as an insecticide. Dieldrin is closely related to aldrin, which reacts further to form dieldrin. Aldrin is not toxic to insects; it is oxidized in the insect to form dieldrin which is the active compound. Both dieldrin and aldrin are named after the Diels-Alder reaction which is used to form aldrin from a mixture of norbornadiene and hexachlorocyclopentadiene. Originally developed in the 1940s as an alternative to DDT, dieldrin proved to be a highly effective insecticide and was very widely used during the 1950s to early 1970s. Endrin is a stereoisomer of dieldrin. However, it is an extremely persistent organic pollutant; it does not easily break down. Furthermore, it tends to biomagnify as it is passed along the food chain. Long-term exposure has proven toxic to a very wide range of animals including humans, far greater than to the original insect targets. For this reason, it is now banned ...

Cyanide
Cyanide is a naturally occurring, rapidly acting, toxic chemical that can exist in many different forms. In chemistry, a cyanide () is a chemical compound that contains a functional group. This group, known as the cyano group, consists of a carbon atom triple-bonded to a nitrogen atom. In inorganic cyanides, the cyanide group is present as the anion . Soluble salts such as sodium cyanide (NaCN) and potassium cyanide (KCN) are highly toxic. Hydrocyanic acid, also known as hydrogen cyanide, or HCN, is a highly volatile liquid that is produced on a large scale industrially. It is obtained by acidification of cyanide salts. Organic cyanides are usually called nitriles. In nitriles, the group is linked by a covalent bond to carbon. For example, in acetonitrile (), the cyanide group is bonded to methyl (). Although nitriles generally do not release cyanide ions, the cyanohydrins do and are thus rather toxic. Bonding The cyanide ion is isoelectronic with carbon m ...

Anoxic Waters
Anoxic waters are areas of sea water, fresh water, or groundwater that are depleted of dissolved oxygen. The US Geological Survey defines anoxic groundwater as those with dissolved oxygen concentration of less than 0.5 milligrams per litre. Anoxic waters can be contrasted with hypoxic waters, which are low (but not lacking) in dissolved oxygen. This condition is generally found in areas that have restricted water exchange. In most cases, oxygen is prevented from reaching the deeper levels by a physical barrier, as well as by a pronounced density stratification, in which, for instance, heavier hypersaline waters rest at the bottom of a basin. Anoxic conditions will occur if the rate of oxidation of organic matter by bacteria is greater than the supply of dissolved oxygen. Anoxic waters are a natural phenomenon, and have occurred throughout geological history. The Permian–Triassic extinction event, a mass extinction of species from the world's oceans, may have resulted fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eutrophication
Eutrophication is the process by which an entire body of water, or parts of it, becomes progressively enriched with minerals and nutrients, particularly nitrogen and phosphorus. It has also been defined as "nutrient-induced increase in phytoplankton productivity". Water bodies with very low nutrient levels are termed oligotrophic and those with moderate nutrient levels are termed mesotrophic. Advanced eutrophication may also be referred to as dystrophic and hypertrophic conditions. Eutrophication can affect freshwater or salt water systems. In freshwater ecosystems it is almost always caused by excess phosphorus. In coastal waters on the other hand, the main contributing nutrient is more likely to be nitrogen, or nitrogen and phosphorus together. This depends on the location and other factors. When occurring naturally, eutrophication is a very slow process in which nutrients, especially phosphorus compounds and organic matter, accumulate in water bodies. These nutrients de ...

Insecticide
Insecticides are substances used to kill insects. They include ovicides and larvicides used against insect eggs and larvae, respectively. Insecticides are used in agriculture, medicine, industry and by consumers. Insecticides are claimed to be a major factor behind the increase in the 20th-century's agricultural productivity. Nearly all insecticides have the potential to significantly alter ecosystems; many are toxic to humans and/or animals; some become concentrated as they spread along the food chain. Insecticides can be classified into two major groups: systemic insecticides, which have residual or long term activity; and contact insecticides, which have no residual activity. The mode of action describes how the pesticide kills or inactivates a pest. It provides another way of classifying insecticides. Mode of action can be important in understanding whether an insecticide will be toxic to unrelated species, such as fish, birds and mammals. Insecticides may be repe ...

Lenca
The Lenca or Lepawiran "people of the jaguar" are from present day southwest Honduras and eastern El Salvador in Central America. They once spoke many Dialects such as Chilanga, Putun, Kotik etc. Although there were different dialects, they understood and coexisted with each other. These dialects are now nearly extinct. In Honduras, the Lenca are the largest tribal group, with an estimated population of more than 450,000. The pre-Conquest Lenca had frequent contact with various Mayan groups as well as other sovereign tribal people of the territory of present-day Mexico and Central America. The origin of Lenca populations has been a source of ongoing debate among anthropologists and historians. Research has been directed to gaining archaeological evidence of the pre-colonial History Pre-European era Since pre-European times the Lencas occupied various areas of what is now known as Honduras and El Salvador.

Arturo Armando Molina
Colonel Arturo Armando Molina Barraza (6 August 1927 – 18 July 2021) was a Salvadoran politician and military officer, who served as President of El Salvador from 1972 to 1977. He was born in San Salvador. He served between 1 July 1972 and 1 July 1977. The 1973 oil crisis led to rising food prices and decreased agricultural output. This worsened the existent socioeconomic inequality in the country, leading to increased unrest. In response, Molina enacted a series of land reform measures, calling for large landholdings to be redistributed among the peasant population.Walter, Williams (1997). ''Militarization and Demilitarization in El Salvador’s Transition to Democracy''. p. 90. Molina was distrusted by the oligarchy and the right-wing military, and was resented by the opposition from whom he had stolen power. His attempts to silence opposition included the military occupation of the University of El Salvador in 1972, as well as violently suppressing student protests that ...
