"Particle emissions from small non-road and hand-held spark ignition engines have not been and are not regulated, but can be considerable, and given the immediate proximity of the operator to the exhaust, can pose a substantial health risk. In this study, the emissions from a recent production lawnmower have been measured and sampled during real driving conditions using a portable off-board system and an experimental full-flow dilution and sampling tunnel. Particle mass emission rates determined gravimetrically from samples collected on quartz fiber filters exhibited avariance on the order of tens of percent. Variability in engine operating conditions attributed to varying lawn properties is believed to be the prime source of the observed test-to-test variance."@en . "Praha" . "24210" . "5"^^ . . .
