The reduction in lung function was probably associated with high cement dust exposure. In parallel to our findings, Merenu et al. investigated the effect of cement dust exposure on 56 cement factory workers with a mean of 10 years exposure to cement dust on lung function. They found that the vital capacity and forced expiratory volume in …

Cement is composed of rock salt limestone and powdered gypsum, a type of chemical that are formed from non-metallic minerals.. Cement chemically reacts with acid water in the soil and changes the physio-chemical properties of soil which can affect any type of plant or grass.. Soil contains air, water, nitrogen, iron, potassium, manganese, and microbes.
Cement and concrete manufacture Where are the hazards? High levels of dust can be produced when cement is handled, for example when emptying or disposing of bags. ... In the short term, exposure to high levels of cement dust irritates the nose and throat. Longer term exposure could lead to occupational asthma. Mortar can also contain respirable ...
contact with cement dust and consult a physician. • Use soap and water to wash off dust to avoid skin damage. • Wear a P-, N- or R-95 respirator to minimize inhalation of cement dust. • Eat and drink only in dust-free areas to avoid ingesting cement dust. Wet Concrete Hazard: Exposure to wet concrete can result
Concrete dust contained much higher wt.% of silicon, aluminum, and potassium than cement paste, while the cement was rich in calcium. 4. Conclusions. This study reports a comprehensive size and chemical characterization of dust generated during saw-cutting of cement and concrete. Such data is lacking, despite thousands of …
cancer in subjects chronically exposed to cement dust, pine wood dust and coal tar products. The risk associated with cement dust and coal tar product was predominantly related to supra glottis cancer.

The greatest human health risk is from the inhalation of concrete dust. Cement (an ingredient of concrete) may contain trace amounts of heavy metals but a one-time light dusting of garden soil would not likely lead to a worrisome elevation in the soil levels of those metals. Organic matter in soil binds heavy metals making them less …
Thanks for the advice. You'd make a good builder blaming the customer! Not deliberate. Just totally thoughtless. These guys have taken a year of chasing by us and the warranty company to start putting right an 85 page survey with items ranging from a fraudulently carried out air tightness test to a heating system that's never operated, …
Mwaiselage et al. also reported that the concentration of respirable dust by mass was approximately 40% of the "total" dust, suggesting that the mass fraction of larger particles is higher than that of smaller particles in cement dust. To investigate the association between a broader size range of the cement particle exposure and acute ...
This study measured haematological and liver function parameters in workers occupationally exposed to cement dust in order to test the hypothesis that cement dust exposure may perturb these functions. Assessment of haematological parameters and liver function were performed in 23 workers occupationa …
If the cement has only been there for a short period, it may be easier to remove compared to if it has been left untouched for a long time. Fresh cement stains are generally easier to deal with since they haven't fully hardened yet.
