Investigating the sources and magnitude of human exposure to halogenated organic pollutants using advanced methods for environmental analysis.
… in a wide range of samples including air, dust, diet, simulated GIT fluid, human serum and breast milk. The obtained concentrations were used to estimate the exposure of adults, toddlers and nursing infants to the target BFRs via inhalation, dust ingestion and diet using different exposure …

Environmental risk assessment of heavy metals in urban street dust
… presented in a product, a system and/or an industrial process. The results have been used for setting occupational standards and environmental regulations. However, in practice, environmental risk assessment generally does not take into account the bioavailability/mobility of chemicals in …

Metal and Metalloid Contaminants in Atmospheric Aerosols from Mining Operations
… As, Pb, Cd and other potentially toxic elements. Dust particles emitted from mining operations can accumulate in surrounding soils, natural waters and vegetation at relatively high concentrations through wind and water transport. Human exposure to the dust can occur through inhalation and, …

Experimental Investigation of Microparticle Sand Sticking Probability from 1000°C to 1100°C
… are increasing the likelihood of sand and dust ingestion. Turbine engines are particularly susceptible to the ingestion of sand and dust, which can erode cold-section components and deposit onto hot-section components. Ultimately, the erosion and deposits will shorten the operational …

A Diagnostic Technique for Particle Characterization Using Laser Light Extinction
… have increased risks of micro-sized particle ingestion into engines. The probability of increased sand and dust ingestion results in increased life cycle costs, in addition to increased potential for performance loss. Thus, abilities to accurately characterize inlet sand would be useful for …

Onset of Arizona Road Dust in High Temperature Environment on a Cooled HASTELLOY X Surface
… there has been an increased interest in sand, dust, and ash particulates ingestion study for gas turbine engine applications. Recently, there has been an increase in commercial and military fleets operating in medium to highly dusty environments, such as areas in Africa, the Middle East, and …

Characterizing the Binding Potential, Activity, and Bioaccessibility of Peroxisome Proliferator Activated Receptor Gamma (PPARγ) Ligands in Indoor Dust
… the primary sink for many of these SVOCs is dust, and dust ingestion has been confirmed as an important pathway for SVOCs accumulation in humans, the potential PPAR binding and activation in extracts from environmentally relevant dust samples was also investigated. </p><p> Previous studies …
