HIGHLIGHTS

  • Cytotoxicities of organic-solvent extracts of generator emissions were studied.
  • Bio-dieselhol with added acetone/butanol (A/B) reduced the U937 cell mortality.
  • The cell mortality decreased as the ratio of added water-containing A/B increased.

 

ABSTRACT


In this investigation, conventional diesel (D), 1–30 vol% waste-edible-oil-biodiesel (WEO-biodiesel, (W), 1–3 vol% pure/water-containing acetone (A/A'' (5% water content)) or 1–50 vol% butanol (B/B' (2% water content)/B'' (5% water content) were tested as fuels and their effects on the cytotoxicity of emissions from a generator at 3 kW load were studied. Human male single cells (U937) and the MTT (3-(4,5-dimethyl-thiazol-2-yl)-2,5-diphenyltetrazolium bromide) method were used to test the cell toxicity of gas- and particle-phase samples (which were obtained by organic-solvent extraction). The results revealed that adding 1–3% acetone/water-containing acetone to bio-dieselhols reduced the mortality of U937 that were exposed to exhaust emissions organic-solvent extraction of to U937 when the generator was loaded at 3 kW. Adding more acetone/water-containing acetone further reduced the mortality of cells that were exposed to the emission gas from organic solvent extraction Compared with water-free butanol, using water-containing butanol (2% or 5%) added WEO-biodiesel further reduced the cytotoxicity (to U937) of organic solvent extracts from the emissions. The mortality of U937 decreased as the added butanol percentage increased in the range of 10−30% but increased as the added butanol percentage was increased to 40% or 50%. Therefore, the water-containing and -free acetone/butanol blending could reduce the toxicity of diesel-engine exhausts.
