Exposure to a variety of toxins and/or infectious agents leads to disease, degeneration and
death, often characterised by circumstances in which cells or tissues do not merely die and …

The essential and naturally occurring transition metal manganese (Mn) is present in the soil,
water, air, and various foods. Manganese can accumulate in the brain if the Mn intake or …

This investigation aims to explore determinants of exposure to particle size-specific welding
fume. Area sampling of ultrafine particles (UFP) was performed at 33 worksites in parallel …

Background Although major concerns exist regarding the potential consequences of human
exposure to nanoparticles (NP), no human toxicological data is currently available. To …

In welding, there is a potential risk due to metal-oxide nanoparticles (MONPs) exposure of
workers. To investigate this possibility, the diameter and number particles concentration of …

Many serious accidents related to work in confined spaces still occur. Despite all the
regulatory and standard-setting efforts that have been made, organizations seem to have …

Arc welding is a common unit operation in the construction industry, where frequent changes
in location and welding position make it more difficult to control fume exposures than in …

We investigated airborne and internal exposure to manganese (Mn) and iron (Fe) among
welders. Personal sampling of welding fumes was carried out in 241 welders during a shift …

Purpose Welding fume consists of metal fumes, eg, manganese (Mn) and gases, eg, ozone.
Particles in the respirable dust (RD) size range dominate. Exposure to welding fume could …

Welding is a major industrial process used for joining metals. Occupational exposure to
welding fumes is a serious occupational health problem all over the world. The degree of …
