Titolo: Incidenza inceneritori

Finrod tempo fa scriveva:
"...lo studio
di cui parla Ladybat, e da cui si evince che anche eliminando gli
inceneritori comunque non tocchi il 99& delle polveri sottili... "
I diretti interessati, o qualcuno altro, mi sanno indicare i
riferimenti di questo studio?
grazie

non riesco a ritrovare il riferimento, immagino fosse postato insieme
alla citazione, ma a muzzo ti mando due dati sulle fonti delle polveri
sottili. sono dati qualitativi e non quantitativi, lo so, ma se vuoi i
numeri temo che te li debbe googlare tu
particles. Very small pieces of solid or liquid matter. Particles of
dust, sea salt, and material from volcanic eruptions occur naturally in
the atmosphere. Sulfate particles are also produced naturally from gases
emitted by marine organisms. Industry and motor vehicles add
significantly to the concentration of particles in the atmosphere – high
concentrations are found in big cities and industrial areas. These
particles remain airborne for long periods, lowering visibility. The
brown haze which is often seen over large cities in autumn, winter and
spring is due mainly to particles.

6. What exactly is particulate matter?
Particulate matter includes a wide range of pollutants -- road dust,
diesel soot, fly ash, wood smoke, and sulfate aerosols that are
suspended as particles in the air. These particles are a mixture of
visible and microscopic solid particles and minute liquid droplets known
as aerosols.
7. Where do fine particles come from?
Combustion of fossil fuels is the principal source of fine particle
emissions, including the burning of coal, oil, diesel fuel, gasoline,
and wood in transportation, power generation, and space heating. Old
coal-fired power plants, industrial boilers, diesel and gas-powered
vehicles, and wood stoves are the worst culprits. High temperature
industrial processes such as metal smelting and steel production are
also significant sources.

"The increased risk of lung cancer and heart disease from air pollution
was clearly far less than the risks associated with active cigarette
smoking," said Arden Pope, professor of economics at Brigham Young
University in Provo, Utah, the study's co-leader. "However, we found
that the risk of dying from lung cancer as well as heart disease in the
most polluted cities was comparable to the risk associated with
nonsmokers being exposed to second hand smoke over a long period of time."

bhe, poi basta googlare, il resto te lo cerchi da solo

 alla citazione,
Se non riesci a trovare un tuo post figurati se posso riuscirci io.
Tu hai citato uno studio,  e Finrod evinceva che gli inceneritori
incidono per l'1% sulle polveri sottili.
Poiche detto cosi non significa niente, volevo capire i termini esatti
della questione.
non lo trovi? pazienza... ma bastava dirlo in due righe.
