Fine particles and mortality.
In an interesting paper in a recent issue (vol 17, issue 14) of the journal, Enstrom examined the association between fine particulate matter (PM) pollution and mortality in a cohort of elderly Californians. The analyses used proportional hazards regression and after adjusting for age, sex, cigarette smoking, and other potential confounders, Enstrom concluded, “These epidemiologic results do no...
متن کاملSeparation of Ultra - Fine Sulphur Particles from Nta Dispersion by Aphron Flotation
Oxidative scrubbing is used to remove H2S from gas streams. A key problem in regeneration of the absorbent is the removal of fine particles of sulphur from the suspension of the scrubbing liquid. Dispersions of ultra-fine bubbles have been called "colloidal gas aphrons" or aphrons for short. These dispersions have interesting properties and it was found that they have particular advantages in t...

متن کاملFine Particles Processing
It is vell known that fines and ultrafines can cause severe problems in mining and mineral processina. The decrease in the grade of ore combined with the arowinS demand for aineral products baa led to the minina and milling of increasing tOQnage or ore. Cl08ely linked with the problem of reduction in the grade of ore is. the more serious problem of the decrease in libration size. A direct cODsq...
متن کاملFine particles and lung cancer.
A lmost five decades have elapsed since the effect of the so-called ‘‘urban factor’’ on lung cancer has been suggested. Air pollution has always been an attractive explanation for the 10–40% increase in lung cancer mortality observed in urban versus rural areas, but confounding from smoking and other factors has been a great limitation in interpreting geographical comparisons. Several attempts ...
