Therefore, this study clearly signifies the effect of quarry dust on kidneys and the same could also be true in humans. Silica nephropathy also referred to as floorboard of kidney …
to dust (Jaber et al., 2015). Inhalable dust is produced when the stone is cut and by the breaking of the stones on the quarry floor during the transit of the vehicles (Ulm et al., 2004). A particular concern in some quarries is the inhalation of dust containing silica which can lead to silicosis, an irreversible lung disease resulting in
Environmental exposure to dust from quarrying activities could pose health dangers to the population living nearby. This study aimed to investigate the health effects of dust exposure on people living close …
This study assessed how work‐post and use of required PPE jointly influence exposure to silica dust and disease symptoms in Ghana. ... This study is part of a research project that assessed the human health risks of occupational exposure to silica dust by stone quarry workers in Ghana. In all, 30 stone quarries were visited in the five ...
Introduction Exposure to dust due to stone quarrying can cause severe respiratory ailments. Besides lung problems, research shows that exposure to quarry dust may also increase the risk of health problems affecting the heart, liver, kidney, central nervous system, and other organs. Despite the fact that a lot of studies have been …
Unfortunately, breathing in silica dust caused by chipping, cutting, drilling, or grinding soil, granite, slate, sandstone or other natural materials can lead to chronic lung disease. ... Silica exposure also increases the risk of bacterial infections, such as tuberculosis. "Depending on the disease and symptoms ranging anywhere from ...

In many dust induced respiratory diseases, the immune system is playing a dual role. Although activation of the immune system is necessary for removal of dust particles, microorganisms and antigens from the airways; an inappropriate or unchecked immune response can result in severe lung disease and pathologic outcomes (Figure …
DISEASES AMONG STONE CORRIE QUARRY WORKERS IN NAMIBIA, 2018 By Saima Shihepo (200806483) ... Objectively the study assessed the amount of silica emitted in quarry dust emissions from selected Namibian quarry mines in compliance with national and WHO Air Quality Standards. Secondly, this
Several clues suggest a genetic or acquired abnormality of immune system as a trigger of the increased production of IgA. In our case report, simultaneous kidney and pulmonary disease could suggest same triggers (e.g. exposure to virus, bacteria or environmental agents) inducing IgA synthesis and pulmonary immune system activation.
Some people with rheumatic or autoimmune diseases, such as rheumatoid arthritis or lupus, develop an autoimmune lung disease. Marked by lung inflammation and possible scarring, it's easier to treat if detected early. Autoimmune diseases occur when the body generates an immune response against itself. Some people with rheumatic or …
Other Health Issues: Research indicates that silica exposure may also be associated with kidney disease and autoimmune disorders. The Rise of Granite Silicosis Lawsuits As awareness of the health risks associated with granite dust exposure has grown, more workers affected by silicosis have sought legal recourse against manufacturers and ...
Community members have also become a victim of respiratory conditions and disorders due to dust expose from surrounding quarry activities. Objective The study assessed respirable dust exposure and the prevalence of respiratory symptoms among quarry workers and community members in the Erongo region of Namibia.
Genetic susceptibility is a key factor in the development of autoimmune diseases. Genome-wide association studies have identified numerous polymorphisms for autoimmune disease development involving the regulatory regions of genes involved with immune responses. 7 The strongest associations found with autoimmune susceptibility …
The inhalation of crystalline silica dust constitutes a risk factor for workers' health. Exposed workers can suffer not only certain cardiovascular diseases, but also pulmonary tuberculosis, silicosis, chronic obstructive disease, some types of neoplasms, autoimmune diseases and kidney disorders [4,5,15].
Immune deficiencies are disorders of the immune system, which result in more frequent infections, more severe infections, and infections with unusual organisms. Primary immune deficiencies (PIDs) are inherited disorders of immune function while secondary immune deficiencies occur as a result of events, such as a viral infection or iatrogenic ...
Further analyses carried out since by the Government Chemist give the following results: (i) Dust collected from a ledge eight feet above the floor and directly above the heads of a splitter and hand dresser contained 46.5 per cent. of free silica and 9.5 per cent. of combined silica, and (ii) dust collected at another quarry from a beam nine ...
Autoimmune disease (when your body's immune system, which is supposed to keep you healthy starts attacking your organs and tissues) The amount of silica in a material or product, the time spent exposed to airborne silica dust and the amount of dust determine how significant or high the risk is to a worker's health.
Exposure to quarry dust without proper protection was reported to even cause lung cancer, which could be prevented if proper precautions were provided by employers. ... or autoimmune disease were disqualified from the trial. 2.7.

There is mounting epidemiologic evidence that exposure to inorganic dust is associated with increased risk of rheumatologic and other autoimmune (AI) diseases. The links between dusty environments and rheumatoid arthritis (RA) are evident among miners, especially coal miners, and are strongly implicated in a number of other silica‐exposed ...
