(PDF) Differences in the biological activity of two PM3.3,

In previous experiments we found differences in the biological effects induced by the two PM components (fine and coarse) on both erythrocytes and macrophages (Diociaiuti et al., 2001).The two PM(2.5) (fine) and PM(2.5-10) (coarse) fractions,,The fine particles were the most effective and the differences between the two size fractions in inducing these biological effects remained unchanged when the basis of comparison was changed from weight to surface measures. It seemed therefore that these differences relied on the different physicochemical nature of the particles.The Two PM2.5 (Fine) and PM2.5–10 (Coarse) Fractions,,Jul 01, 2001· The Two PM 2.5 (Fine) and PM 2.5–10 (Coarse) Fractions: Evidence of Different Biological Activity Author links open overlay panel Marco Diociaiuti a Maria Balduzzi b Barbara De Berardis a Giorgio Cattani c Giordano Stacchini c Giovanni Ziemacki c Achille Marconi c Luigi Paoletti a(PDF) The Two PM2.5 (Fine) and PM2.5–10 (Coarse) Fractions,,The two SD 60.3 0.4 0.69 3.7 0.4 6 433 histograms, even if both are lognormal, are signi7- cantly different from each other, with mean particle diameters of 1.67 and 2.79 lm for the 7ne and coarse fractions, respectively. measurements we obtained SD values comparable Figure 2 shows two typical energy dispersion X- with the means due to the,The Two PM 2.5 (Fine) and PM 2.5–10 (Coarse) Fractions,,Request PDF | The Two PM 2.5 (Fine) and PM 2.5–10 (Coarse) Fractions: Evidence of Different Biological Activity | Recent studies have shown that an increased concentration of environmental,Biological activity - Wikipedia,In pharmacology, biological activity or pharmacological activity describes the beneficial or adverse effects of a drug on living matter.
