Abstract Exposure to diesel fumes and exhaust gases is considered the most frequent form of workplace exposure in France. These emissions are classified as probably carcinogenic to humans (Group 2A) by the IARC. Diesel emission is the source of chemically complex pollution comprising gases and fine carbon particles, onto which complex organic compounds are adsorbed. At present, only the use of a particle filter ensures sufficient reduction in mobile machinery emissions. Multiple technologies have been developed to collect efficiently these particles at the surface of the filter medium and, above all, allow their elimination and thereby regenerate the filter pressure drop. This article presents a study aimed at testing filters fitted to off-road on construction sites to confirm their initial performance and especially their conservation over time. Findings show that certain filter technologies (CRT-type catalyzed passive regeneration) do not appear to be suitable for off-road vehicles. Only active regeneration filters with a complementary additive, which have been widely tested in some countries, appear suitable at present insofar as they ensure significant reduction of soot microparticle emissions and guarantee performance characteristic conservation in time.
