Manganese (Mn) is an essential trace element necessary for physiological processes that
support development, growth and neuronal function. Secondary to elevated exposure or …

Inhalation studies are the gold standard for the estimation of the harmful effects of respirable
chemical substances, while there is limited evidence of the harmful effects of chemical …

Welding fume particles are hazardous. Their toxicity likely depends on their composition and
reactivity. This study aimed at exploring the role of sodium or other fluorides (NaF), which …

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

Increased manganese (Mn) exposure is known to cause cognitive, psychiatric and motor
deficits. Mn exposure occurs in different occupational settings, where the airborne Mn level …

Arc welding processes generate complex aerosols composed of potentially hazardous metal
fumes and gases. Millions of workers worldwide are exposed to welding aerosols daily. A …

Chromium alloying of weld metal is usually accomplished via weld wire. This is done
because chromium has a high affinity for oxygen and is therefore not easily transferred …

Arc welding operations are considered to be risky procedures by generating hazardous
welding fume for human health. This study focuses on the key characteristics, as well as …

Welding-generated metallic fumes contain a substantial amount of manganese (Mn), making
welders susceptible to Mn toxicity. Although overt Mn toxicity manifests as a type of …

Toxic substances produced during welding include heavy metals, carbon monoxide, carbon
dioxide, and nitrogen oxides. The study aims to evaluate the heavy metals concentration in …
