Description
Particulate Matter is a complex mixture of particles that includes many chemical species with a toxicological activity. Although, the toxicity of particulate matter is extensively studied in vitro, very few investigations have been addressed in vivo.
Caenorhabditis elegans is a soil nematode that has been frequently used as a simple model organism to quantify the toxic effects of environmental xenobiotics.
Thus, the effects of samples originated from three relevant components of atmospheric dusts (brake dust, pellet ash and Saharian dust) were analysed. We evaluated the effects of the two fractions of these atmospheric particulate matters with respect to the total: water-soluble and insoluble fractions. The toxicity of these fractions was analyzed by evaluating the ability to affect the C. elegans survival as well as their capacity to induce oxidative stress in worm populations.
