Mutagenicity and Lung Toxicity of Smoldering vs. Flaming Emissions from Various Biomass Fuels: Implications for Health Effects from Wildland Fires.
BACKGROUND The increasing size and frequency of wildland fires are leading to greater potential for cardiopulmonary disease and cancer in exposed populations; however, little is known about how the types of fuel and combustion phases affect these adverse outcomes. OBJECTIVES We evaluated the mutagenicity and lung toxicity of particulate matter (PM) from flaming vs. smoldering phases of five b...
متن کاملThe effect of short-term of fine particles on daily respiratory emergency in cities contaminated with wood smoke
BACKGROUND AND OBJECTIVES: The goal of this study is to evaluate in a time-series study the short-term effects of particulate matter-2.5exposure on respiratory emergency visits in six central-southern Chilean cities highly contaminated by wood smoke. METHODS: Association was assessed using both distributed lag linear and non-linear Poisson models constrai...
متن کاملRetinol and ?-Carotene inhibit PTZ-induced kindling in mice
Vitamin A and its derivatives have recently reported to be implicated in synaptic plasticity. The possible effect of vitamin A and its precursor, ?-carotene, on seizure acquisition was tested in PTZ kindling model of epilepsy. Vitamin A and ?-carotene were tested for their ability to 1) suppress seizures (clonic and tonic) and lethality induced by PTZ in PTZ-kindled mice (anticonvulsant effect)...
متن کاملSome Observations of Two-dimensional Smoldering and the Transition to Flaming
Experiments have been conducted to study the upward smolder characteristics and the phenomenon of transition to flaming of a porous combustible material in the presence of an air/porous-solid interface. External air flow velocities ranging from 0 m/s to 2.5 m/s are forced upward and forward across the exposed, flat, vertical surface of a high void fraction, flexible, polyurethane foam to examin...
متن کاملControlling Mechanisms in the Transition from Smoldering to Flaming of Flexible Polyurethane Foam
Experiments have been conducted to study the controlling mechanisms involved in the transition from smoldering to flaming of a porous combustible material, flexible polyurethane foam, with an air flow forced across one of the porous-fuel surfaces. The experiments are performed in a small-scale, vertical, combustion wind tunnel, with the air flow forced upward and parallel to an exposed foam sur...
