Abstract: Objectives: The inflammatory effects of organic sub-10 nm particles generated and emitted from a diesel engine fueled with a biodiesel and a commercial diesel oil are analyzed in this paper. Diesel combustion is the major sources of ultrafine particles (UFP) in the environment, particularly in urbanized areas. In the last years, there is an increasing use of biomass-derived fuels because they are a renewable source of energy that may mitigate climate change through the reduction of net CO2 with respect to conventional fossil fuels. Although there is a general agreement on biofuels ability to reduce conventional pollutants, new and potentially harmful pollutants can be formed during biofuel combustion. In particular, the emission of sub-10 nm particles is strongly increased with respect to that of larger soot particles.

Altro abstract: Methods: Organic sub-10 nm particles are separated from larger sizes particulate matter by collection in water suspension for toxicological and inflammatory tests. After exposure to sub-10 nm particles, the effects on proliferation, apoptosis and secretion of cytokines, chemokines and growth factors networks production is analyzed in immortalized non-tumorigenic human dermal keratinocyte cell line (HaCaT) and human alveolar epithelial-like cells (A549).
