nitrat

Definition of nitrat in English English dictionary
nitrate: Any salt or ester of nitric acid
nitrate: To treat, or react, with nitric acid or a nitrate
nitrate: {n} a salt formed by nitric acid and a base
nitrate: An important nutrient source of nitrogen to plants with known adverse human health effects when found in elevated concentrations in drinking water Major sources of nitrates are septic systems, animal feed lots, agricultural fertilizers, manure, industrial waste waters, sanitary landfills and garbage dumps
nitrate: Mildly toxic end product of biological filtration Can be used as a gauge to tell when a partial water change is needed
nitrate: Nitrate is a chemical compound that includes nitrogen and oxygen. Nitrates are used as fertilizers in agriculture. High levels of nitrate occur in Eastern England because of the heavy use of fertilizers. used in the name of substances containing nitrogen and oxygen. Nitrates are often used to improve soil (nitrique; NITRIC ACID). Any salt or ester of nitric acid (HNO3). The salts are inorganic compounds with ionic bonds, containing the nitrate ion (NO3^-) and any cation. Many, particularly ammonium nitrate, are used as agricultural fertilizers (see saltpeter). Their runoff in surface water and groundwater can cause serious illness in humans. The esters are organic compounds with covalent bonds, having the structure RONO2, in which R represents an organic combining group such as methyl, ethyl, or phenyl
nitrate: An ion that, while harmless in itself, can be reduced to nitrite by certain "wort spoiler" bacteria
nitrate: A salt of nitric acid
nitrate: {f} add nitric acid (Chemistry)
nitrate: Any salt of nitric acid, having the molecular formula NO3-
nitrate: NO3 the final product in the nitrogen cycle It is not toxic, but can be dangerous at high levels Nitrate is created by the oxidation of nitrite by nitrobacter bacteria In a reef tank, nitrate levels should be kept below 10 ppm
nitrate: A compound containing nitrogen and oxygen that can exist in the atmosphere or in water and that can have harmful effects on humans and animals at high concentrations
nitrate: treat with nitric acid, so as to change an organic compound into a nitrate; "nitroglycerin is obtained by nitrating glycerol"
nitrate: (NO3) a chemical formed when nitrogen from ammonia (NH3), ammonium (NH4) and other nitrogen sources combines with oxygenated water
nitrate: A nitrogen-containing compound that can exist in the atmosphere or as a dissolved gas in water Nitrates are found in fertilizers, and human and animal wastes Nitrate pollution of drinking water is increasing, especially in states like Florida where fertilizers are commonly used and groundwater deposits are relatively shallow and vulnerable to pollution Nitrates and nitrites can combine to form toxic nitrosamines, which are mutagenic, teratogenic, and carcinogenic Nitrates can harm humans and animals; they are especially dangerous to infants Because they limit the body's ability to carry oxygen to the cells, they can cause brain damage and death
nitrate: Sodium nitrate or potasium nitrate compounds used as fertilizer
nitrate: A chemical compound having the formula NO-3 Nitrate salts are used as fertilizers to supply a nitrogen source for plant growth Nitrate addition to surface waters can lead to excessive growth of aquatic plants High groundwater nitrate levels can cause Methemoglobinemia in infants ADVANCE \x 540
nitrate: A form of nitrogen that rapidly converts to nitrate (NO3-) and is usually included in the NO3- analysis
nitrate: a compound containing nitrogen that can exist in the atmosphere or as a dissolved gas in water and which can have harmful effects on humans and animals Nitrates in water can cause severe illness in infants and domestic animals A plant nutrient and inorganic fertilizer, nitrate is found in septic systems, animal feed lots, agricultural fertilizers, manure, industrial waste waters, sanitary landfills, and garbage dumps
nitrate: An ion consisting of nitrogen and oxygen (NO3-) Nitrate is a plant nutrient and is very mobile in soils
nitrate: The nitrogen ion, NO3-, is derived from nitric acid and is an important source of nitrogen in fertilizers Nitrate pollution of drinking water, shallow wells being particularly vulnerable, is of concern because infants are especially sensitive A nitrate drinking water standard has been set under the Safe Drinking Water Act An Environmental Protection Agency national survey of drinking water wells conducted from 1988 to 1990 indicated that 2 4% of rural domestic wells contained nitrate at or above the 10 mg/L standard Higher rates of contamination have been found in areas of high vulnerability; for example, surveys along the upper Des Moines river indicate that 20 to 30% of wells exceed the standard
nitrate: is the most completely oxidized form of nitrogen It is formed during the final stages of biological decomposition, either in wastewater treatment facilities or in natural water supplies Inorganic nitrates such as ammonium nitrate are commonly used as fertilizers Low-level nitrate concentrations may be present in natural waters However, a maximum of 10 ppm nitrate nitrogen is allowed in drinking water supplies Excessive nitrate concentrations may indicate the presence of heavy fertilizer runoff or excessive discharge from a waste treatment facility (http: //www chemetrics com/)
nitrate: An inorganic form of nitrogen important for plant growth Nitrogen is in this stable form when oxygen is present Nitrate often contaminates groundwater when water originates from manure pits, fertilized fields, lawns or septic systems High levels of nitrate-nitrogen (over 10 mg/1) are dangerous to infants and expectant mothers A concentration of nitrate-nitrogen (NO3-N) plus ammonium-nitrogen (NH4-N) of 0 3 mg/l in spring will support summer algae blooms if enough phosphorus is present
nitrate: (NO²-) a water-soluble form of nitrogen usable by plants when nitrites are unavailable
nitrate: {i} salt or ester of nitric acid (Chemistry)
nitrate: Form of nitrogen commonly found in the soil and used by plants for building amino acids, DNA and proteins It is commonly produced by the chemical modification of nitrite by specialized bacteria Chemical formula for nitrate is NO3-
nitrate: – A salt of nitric acid (NO3-) Nitrates are often highly soluble and can be reduced to form nitrites or ammonia
nitrate: NO3, this is a product in the nitrogen cycle It is not toxic, though at high levels can cause some distress In a reef tank it should be kept as low as possible, under 10ppm Fish only tanks can generally stand 30-40ppm
nitrate: An air pollutant particle containing the NO3 ion
nitrate: any compound containing the nitrate group (such as a salt or ester of nitric acid)
nitrate: 1) A salt or ester of nitrous acid Concentrations greater than 45 ppm can be toxic 2) Intermediate breakdown product of biological wastes Common component of nutrient loading in aquatic environments 3) Vital nutrient for plant growth 4) Inorganic fertilizer that enters water supply sources from septic systems, animal feed lots, agricultural fertilizers, manure, industrial waste waters, sanitary landfills and garbage dumps
nitrate: any compound containing the nitrate group (such as a salt or ester of nitric acid) treat with nitric acid, so as to change an organic compound into a nitrate; "nitroglycerin is obtained by nitrating glycerol
nitrate: A form of nitrogen that is available to plants as a nutrient In high concentrations, it is a water pollutant
