"It's probably wise to inspect for lead-based-paint as well," he said, explaining that if such paint is used on the wall, precautions must be taken to prevent the migration of lead dust and chips out of the area being worked on.
However, LeFevre et al. interpreted their findings of high black pigment scores in liver and spleen of coal miners differently namely, as migration of coal dust in the pneumoconiotic lung into pulmonary lymphatics and then to the systemic circulation, and also as migration of coal mine dust laden macrophages through the walls of pulmonary blood vessels.
Drift exposure included any of the following pesticide exposures outside their intended area of application: a) spray, mist, fumes, or odor during application; b) volatilization, odor from a previously treated field, or migration of contaminated dust; and c) residue left by offsite movement.
In terms of dust migration performances, the migration ability of the head-on dusts weakened at a smaller distance from the exhaust outlet, which also firstly decreased and then increased with increasing pressure airflow capacity.
In order to provide theoretical guidance for effective dust prevention and treatment in the heading face, a simulation system was designed to investigate the migration behaviors of airborne dusts, and the effects of ventilation parameters on airflow and migration of head-on dusts in the heading face were analyzed through the simulations.
Eolian sand migration caused repeated entrainment of dust leading to east-southeastward transport.
These include the study of carbon deposition in gaps and metallic mirrors as a function of temperature, study of dust migration from the divertor, study of methane injection in order to benchmark chemical sputtering diagnostics, and the measurement of charge exchange neutrals with a hydrogen sensor.
The main focus is on the Dust and Activity Migration and Distribution (DAMD) software code system that models the activation, migration and time-dependent distribution of dust and atomic particles in an HTR such as the AVR and PBMR.
Migration of phthalates into house dust and resuspension of phthalate-containing particles into breathing zone.
The grain charge is an important parameter determining its migration through the space, coagulation, formation of dust clouds and so on.
