One-third of the Earth's surface is a potential source of dust. This dust changes spatially throughout the year following the season. The Sahara desert is the largest source of mineral dust in the world. According to studies on climate change, dust from this region accounts for 40 percent of global emissions. Desert dust is known to be the dominant element in the emission of solar radiation in the North Atlantic. Due to their absorption and diffusion properties, these natural aerosols (mineral dust) have a serious impact on solar radiation and therefore on the earth's radiation balance.
In addition, studies are carried out on the effects of average temperature, average precipitation and sea level pressure. A rapid increase in global average temperature is observed, along with increases in global average precipitation and decreases in sea ice cover.
Dust particles, a suspension of small soil particles in the atmosphere, contribute to the atmospheric aerosol load. With the help of winds, dust particles suspended in the air are carried to distant places. Dust in the air affects atmospheric dynamics and stimulates cloud and precipitation formation processes that alter the hydrological cycle. Mineral dust particles increase micronutrients and bioproductivity, thus affecting the global carbon cycle.
On the other hand, the EPA Method 17 standard has been developed by the American Environmental Protection Agency (EPA) to determine the amount of dust emission by taking into account the temperature and pressure changes in the flue gas. This method does not include all the specifications required for performance, such as equipment and consumables and procedures. To obtain reliable results, at least the additional test methods included in the Method 1, Method 2, Method 3 and Method 5 standards should also be applied.
Particulate matter is not an absolute quantity, it is a function of temperature and pressure. Therefore, the temperature and pressure at which dust is to be measured must be carefully defined to avoid variation in particulate matter emission regulations and related test methods. Temperature has a greater influence than pressure on the amount of particulate matter in a waste gas stream. The effect of pressure is often neglected.
Among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, our organization also provides dust emission determination services by taking into account temperature and pressure changes, with its trained and expert staff and advanced technological equipment.
