coni: from ancient Greek (κόνις, kónis) which means dust-osis: from ancient Greek, suffix to indicate a medical condition; This word was invented at a meeting of the National Puzzlers' League (N.P.L.) by its president Everett M. Smith.
Because the ash cloud was dry, it did not appear on the weather radar, which was designed to detect the moisture in clouds. The dust in the cloud deprived the engines of sufficient oxygen from the atmosphere to maintain combustion, sandblasted the windscreen and landing-light covers, and clogged the engines.
The types of minerals present in volcanic ash are dependent on the chemistry of the magma from which it erupted. Considering that the most abundant elements found in silicate magma are silicon and oxygen, the various types of magma (and therefore ash) produced during volcanic eruptions are most commonly explained in terms of their silica content.
Several parts of Southern California are currently under a windblown dust and ash advisory as deadly wildfires continue to burn across the region. The advisory covers large sections of Los Angeles ...
Analysis of the contents of ash samples from Vietnam [10] and Singapore [11] shows that joss paper burning can emit many pollutants detrimental to air quality. There is a significant amount of heavy metals in the dust fume and bottom ash, e.g., aluminium, iron, manganese, copper, lead, zinc and cadmium. [10] [11]
The smoke and ash from structures and cars can contain more than a hundred toxic chemicals and poisonous gases, according to state officials. Perhaps the most notable is lead, a heavy metal ...
Volcanic ash deposits on a parked McDonnell-Douglas DC-10-30 during the 1991 eruption of Mount Pinatubo, causing the aircraft to rest on its tail.While falling ash behaves in a similar manner to snow, the sheer weight of deposits can cause serious damage to buildings and vehicles, as seen here, where the deposits were able to cause the 120 ton airliner's centre of gravity to shift.
Pneumoconiosis is the general term for a class of interstitial lung disease where inhalation of dust (for example, ash dust, lead particles, pollen grains etc) has caused interstitial fibrosis. [1] [2] The three most common types are asbestosis, silicosis, and coal miner's lung. [3]
