A growing number of workers in the US are contracting a deadly disease caused by inhaling silica dust when cutting trendy quartz worktops.
Researchers at the University of California, Los Angeles, have linked the surge in cases to a new type of engineered quartz countertop that releases more silica dust during cutting. The condition, known as silicosis or “black lung,” is often misdiagnosed and can be fatal unless treated with a lung transplant.
According to a recent study, 70 cases of silicosis have been reported in California since 2019, despite fewer than five cases being recorded annually prior to this period. The researchers found that up to four in five cases went undiagnosed on initial examination, leading to delayed treatment and potentially life-saving interventions.
The American Lung Association warns that prolonged exposure to silica dust can lead to nodules forming in the lungs, reducing lung capacity, and making it difficult to breathe. In severe cases, patients may require oxygen therapy and other devices to assist with breathing.
Experts urge workers in the construction industry to take precautions, such as wearing face masks or using cutting machines that spray water onto the stone during processing. However, many of these workers are vulnerable due to their immigration status and limited access to healthcare resources.
The US is estimated to have over 2 million workers exposed to silica dust each year, with more than half of workplaces exceeding the maximum permissible limit for air quality. The lack of exposure and screening in this industry poses a significant risk to public health.
Silicosis carries no cure, but early diagnosis and treatment can help alleviate symptoms and improve lung function. The disease also increases the risk of other health problems, including tuberculosis, lung cancer, and chronic bronchitis.
