Since the iron-age and throughout the industrial age, humans have been exposed to iron oxides. Here, we review the evidence from epidemiology, toxicology, and lung bioavailability as to whether iron oxides are likely to act as human lung carcinogens ...

Comparison of Ultrastructural Cytotoxic Effects of Carbon and Carbon/Iron Particulates on Human Monocyte-Derived Macrophages [PDF]
In this study, we tested the hypothesis that the presence of iron in carbon particulates enhances ultrastructural perturbation in human monocyte-derived macrophages (MDMs) after phagocytosis.

Particulate Mercury and Particulate Organic Matter in the Itenez Basin (Bolivia) [PDF]
In rivers and other freshwater bodies, the presence of mercury can be due to direct contamination by anthropic activities such as gold mining. However, it can also be attributed to atmospheric deposition and erosion, runoff, or lixiviation from surrounding soils.

Sampling For PM10 and PM2.5 Particulates [PDF]
Particulate matter is the term given to the tiny particles of solid or semi-solid material found in the atmosphere. Particulates in the atmosphere range in size across many orders of magnitude.

The relevance of the evolution of experimental studies for the interpretation and evaluation of some trace physical evidence [PDF]
In order for trace evidence to have a high evidential value, experimental studies which mimic the forensic reality are of fundamental importance.

Environmental and occupational inhalants may induce a large number of pulmonary diseases, with asbestos exposure being the most risky. The mechanisms are clearly related to chemical composition and physical and surface properties of materials.

Instillation of Particulate Suspensions to the Lungs
Inhaled fine particulates are thought to cause chronic pulmonary inflammation through the deposition of particulates into the lungs. To investigate the effect of fine particulates on the lungs, instillation of suspension of particulates into the lungs is

Continuum approach based on radiation distribution function for radiative heat transfer in densely packed particulate system [PDF]
The study of radiative heat transfer in particulate system is usually based on radiative transfer equation (RTE) with effective radiative properties. However, for non-random, densely and regularly packed particulate systems, the applicability of RTE is questionable due to dependent scattering and weak randomness of particle arrangement.

Comparison of aerosol emissions during specific speech tasks [PDF]
The study of aerosols and droplets emitted from the oral cavity has become increasingly important throughout the COVID-19 pandemic. Studies show particulates emitted while speaking were generally much smaller compared to coughing or sneezing. However, recent investigations revealed that they are large enough to carry respiratory contagions.
