Threshold limits for ultrafine particles (UFPs), which are particles with an aerodynamic diameter of 0.1 µm (100 nm) or less, are not yet clearly established due to the complex nature of their impact on health and the environment. The current occupational aerosol standards, which have been historically based on the mass concentration of airborne particulate matter, do not adequately address the unique characteristics and potential risks posed by UFPs. This is partly because UFPs, despite their modest mass and size, have a significant presence in terms of the number of particles and their ability to reach the most distal lung regions, bypassing primary airway defenses. The historical debates over silica threshold limit values highlight the challenges in establishing protective standards for particulate matter, including UFPs, due to intense political and economic negotiations. Furthermore, the particle emissions from diesel and direct injection gasoline vehicles, which are a major source of UFPs, have prompted recent legislation to limit allowed particle emissions, leading to the introduction of new engine technologies and exhaust aftertreatment systems. Experimental evidence suggests that exposure to UFPs may cause severe health effects, indicating the need for characterizing biologically relevant exposure metrics beyond mass concentration, such as number, size, surface area, shape, solubility, and chemical reactivity. The variability in UFP properties depending on their sources, such as vehicle emissions, further complicates the establishment of threshold limits. Regulatory efforts, such as those by the Commission of the European Union and the United States Environmental Protection Agency, have focused on setting limit values for pollutants like PM10, but specific limits for UFPs remain underdeveloped. In summary, while there is a recognized need for threshold limits for UFPs to protect human health and the environment, the development of such standards is challenged by the particles' complex characteristics, variable sources, and the need for a multidimensional approach to measuring exposure.How does pellet wood compare to wood environmental?
