Welding hazards: The effects of manganese on the brain

Welders can be exposed to toxic fumes -
but manganese can affect the public as well.
In a new study, Penn State College of Medicine researchers try to understand the effects of metal manganese on brain functions.

They aim to expand on the insights of a previous, smaller scale study, which looked at welders specifically, since they are often exposed to manganese in the welding fumes.

But the general population should also be aware of manganese and its effects, the researchers say, since we may all be exposed to the toxin through gasoline additives and the burning of fossil fuels.

According to research, very low concentrations of manganese are essential for life, but high levels of exposure quickly become toxic for humans.

In the previous study on welders, the researchers found a link between exposures to manganese-containing welding fumes and decreased motor performance.

Technical advances make it easier for the researchers to study the effects of manganese exposure in the brain, so they are hoping to see how manganese affects the general population.

The study has received funding from the National Institute of Environmental Sciences.

Reduce exposure to welding fumes and other occupational hazards
Electrocorp fume extractor
(other models available)

Welders have to make sure they don’t breathe in too many welding fumes, which have been shown to be toxic.

Along with the usual precautionary measures (including good ventilation and personal protective equipment), Electrocorp’s industrial-strength welding fume extractors can help reduce exposures.

The welding fume extractors feature the most effective activated carbon blends for the removal of toxic chemicals, gases and fumes, the deepest carbon beds for more efficient adsorption and easy-to-use source capture attachments for more accurate toxin removal.

Electrocorp also features other air cleaners for a wide range of commercial and industrial applications, which contain activated carbon and HEPA air filters.
