Special Issue Information

Dear Colleagues,

The Special Issue “Toxicity and Health Effects of Ultrafine Particulate Matter (UFP) Exposure” will delve into the diverse health impacts of UFP on humans. It will cover toxicological mechanisms, interactions with biological systems, and health outcomes such as respiratory, cardiovascular, and neurological diseases. The goal is to consolidate current research, foster interdisciplinary dialogue, and identify knowledge gaps, thus contributing significantly to the existing literature.

Situated within global air pollution concerns, this issue will address regional variations in UFP exposure and extend discussions to include microplastics’ role in contributing to ultrafine particulate burdens. It aims to be a vital resource for researchers, policymakers, and public health professionals, highlighting the need for effective mitigation strategies and regulatory measures to safeguard public health.

Vehicular emissions are a major culprit in the rise of urban air pollution. The particulate matter (PM) emitted from vehicular sources includes primarily ultrafine particles (UFPs) with aerodynamic diameters less than 0.1 µm (PM0.1) and is linked to adverse respiratory and cardiovascular health effects. Despite this knowledge, few exposure assessment studies exist that detail the physicochemical properties of PM in parking garages. In this study, airborne PM emitted by vehicles in a parking garage of a hospital in New Jersey was sampled, during winter and summer seasons, and physicochemically characterized. The results indicate that the mass concentrations of the UFPs in the garage were 2.51 µg/m3 and 3.59 µg/m3, respectively. These UFPs contained a large percentage of elemental carbon and toxic elements. They also contained polycyclic aromatic hydrocarbons (PAHs), having deleterious health effects. An inhalation particle modeling revealed that 23.61% of these UFPs are deposited in the pulmonary region of the lung, translating to a dose of 10.67 µg for winter and 15.25 µg for summer, over a typical 40 h work week. These high deposited levels of UFPs and their complex chemistry levels further warrant the need for toxicological assessment of UFPs related to vehicular emissions. Full article
