Definition von particulates im Englisch Englisch wörterbuch: any set of particles that are suspended in air or water With respect to air pollution, particulates are a complex mixture of solid and liquid particles (aerosols) in the atmosphere such as dust, smoke, and soot in the atmosphere; Particulates are emissions of soot and particles of partially combusted fuel components They are of particular concern in compression ignition (diesel) engines Ethanol can dramatically reduce particulate emissions; Tiny pieces of solid or liquid matter, such as soot, dust, fumes, or mist; A fine liquid or solid particle such as dust, smoke, mist, fumes, or smog, found in air or emissions; atmospheric particles made up of a wide range of natural materials (e g , pollen, dust, resins), combined with manmade pollutants (e g , smoke particles, metallic ash); in sufficient concentrations, particulates can be a respiratory irritant Primary sources of manmade particulate emissions are industrial process losses (e g from cement plants) and stationary combustion sources Motor vehicles contribute a relatively minor amount of particulates PCB - polychlorinated biphenyl, a class of synthetic chemicals consisting of an homologous series of compounds beginning with monochlorobiphenyl and ending with decachlorobiphenyl PCB’s do not occur naturally in petroleum, but have been found as contaminants in used oil PCB’s have been legally designated as a health hazard, and any oil so contaminated must be handled in strict accordance with state and federal regulations PCV - see positive crankcase ventilation; Airborne solid impurities such as those present in gaseous emissions (sodium sulphate, lime, calcium carbonate, soot); 1 Fine liquid or solid particles such as dust, smoke, mist, fumes, or smog, found in air or emis- sions 2 Very small solids suspended in water; they can vary in size, shape, density and electrical charge and can be gathered together by coagulation and flocculation; Small particles, especially those in the atmosphere; Visible air pollutants consisting of particles appearing in smoke or mist emitted by the combustion of fossil fuels, primarily in the transportation, industrial, or electric utility sectors, or consisting of naturally occurring substances such as airborne dust particles; The Environmental Protection Agency has set National Ambient Air Quality Standards for particulates One, in effect since 1987, regulates particles smaller than 10 microns in diameter (PM10); the other, promulgated in 1997, would regulate particles smaller than 2 5 microns in diameter (PM2 5) - but court challenges are delaying its implementation These are of interest to agriculture because dust from tillage and smoke from burning field residues may contribute to pollutant levels Whether controls might be imposed on agricultural activities depends largely on how each state chooses to meet the standards, however; harmful dust in the air, especially produced by car engines; Fine liquid or solid particles such as dust, smoke, mist, fumes, or smog that are found in air or emissions; Carbon particles formed by partial oxidation and reduction of hydrocarbon fuels Also included are quantities of trace metal oxides and nitrates originating from engine wear, component degradation and inorganic fuel additives In the transportation sector, particulates are emitted mainly from diesel engines; Fine liquid or solid particles such as dust, smoke, mist, fumes, or smog, found in the air or emissions; Airborne particles including dust, smoke, fumes, mist, spray, and aerosols Also see pollutant; Solid particles suspended in a gas or liquid; Tiny pieces of solid or liquid matter, such as soot, dust, fumes, or mist, that can be suspended in the atmosphere; Particles such as dust, mist, fume, smoke or spray that are small enough to be inhaled; 1 Fine liquid or solid particles such as dust, smoke, mist, fumes, or smog, found in air or emissions 2 Very small solids suspended in water; they can vary in size, shape, density and electrical charge and can be gathered together by coagulation and flocculation; Fine liquid or solid particles such as dust, smole, mist, fumes or smog, found in the air or emissions; very small pieces of solid or liquid matter such as particles of soot, dust, fumes, mists or aerosols The physical characteristics of particles, and how they combine with other particles, are part of the feedback mechanisms of the atmosphere (Source: Mintzer, 1992); Finely divided solid or liquid (other than water) particles in the air; 1) Fine liquid or solid particles such as dust, smoke, mist, fumes, or smog found in air or emissions 2) Very small solids suspended in water They vary in size, shape, density, and electrical charge, and can be gathered together by coagulation and flocculation; Solid material small enough to remain suspended in the air; plural of particulate; Carbon particles formed by partial oxidation and reduction of the hydrocarbon fuel Also included are trace quantities of metal oxides and nitrides, originating from engine wear, component degradation, and inorganic fuel additives In the transportation sector, particulates are emitted mainly from diesel engines; Solid particles of soot and other substances that result from combustion
particulate: any solid or liquid suspended in air or free to suspend in air
particulate: Composed of distinct particles Smoke is particulate; pure gases are not
particulate: Comprised of particles; as, particulate matter
particulate: – Consisting of very small, separate particles
particulate: Referring to, or produced by, particles, such as dust, minute germs, etc
particulate: A very small solid suspended in water which can vary widely in size, shape, density, and electrical charge Colloidal and dispersed particulates are artificially gathered together by the processes of coagulation and flocculation
particulate: Particulate is any material in a finely divided state that is suspended in a gas However, the definition of the term is complicated by the fact that materials can change state (change from vapor to liquid) very rapidly, and thereby form particles Over the last ten years, six different classifications of particulate have emerged
particulate: Having the form of a particle
particulate: To particularize
particulate: a small discrete mass of solid or liquid matter that remains individually dispersed in gas or liquid emissions (usually considered to be an atmospheric pollutant)
particulate: a very small solid suspended in air or water which can vary widely in size, shape, density, and electrical charge
particulate: The idea that biological traits are controlled by individual factors rather than by a single all-encompassing hereditary agent
particulate: Consisting of many small individual particles, not dissolved
particulate: {i} substance that is composed of separate particles
particulate: any solid or liquid in a subdivided state, especially one that exhibits special characteristics which are negligible in the bulk material
particulate: a particle of solid or liquid matter; soot, dust, aerosols, fumes and mists
particulate: A particle of solid or liquid matter Particle aerodynamic diameters of biological interest range up to 100 ?m
particulate: a small particle of solid matter or a droplet of liquid of a size that allows it to remain suspended in air
particulate: A state of matter in which solid or liquid substances exist in the form of aggregated molecules or particles Airborne particulate matter is typically in the size range of 0 01 to 100 micrometers Particulate matter is a suspension of fine solid or liquid particles in air, such as dust, fog, fume, mist, smoke, or sprays Particulate matter suspended in air is commonly known as an aerosol
particulate: Particulates are very small particles of a substance, especially those that are produced when fuel is burned. the particulate pollution in our atmosphere
particulate: of or relating to minute discrete particles; a particulate substance
particulate: composed of distinct particles
particulate: Minute, separate particles
particulate: Small, separate pieces of an airborne material Generally, anything that is not a fiber and has an aspect ratio of 3 to 1
