Doctors are calling for a ban on artificial stone, a popular material used for kitchen worktops, following the confirmation of eight cases of artificial stone silicosis in the UK for the first time.
Also known as engineered or reconstituted stone, artificial stone has gained popularity for its aesthetics and durability over the last two decades. However, a new report published in the British Journal of Construction highlights the serious health risks posed by its high silica content, which exceeds 90% compared to 3% in marble and 30% in granite.
“Silicosis is a progressive lung disease caused by inhaling crystalline silica dust,” said Dr. Patrick Howlett, a spokesperson for BBC Science Focus. “The risk of developing silicosis is significantly higher for workers in the artificial stone industry compared to those with chronic respiratory conditions.”
“Various industries expose individuals to silicosis, including mining, pottery, cement work, and now artificial stone fabrication. Prolonged exposure to low levels of silica dust can lead to the development of silicosis over time,” added Dr. Howlett.
All eight affected individuals were male, with an average age of 34, and most worked for small businesses with fewer than 10 employees. Poor safety practices, such as inadequate respiratory protection and ventilation systems, were reported by workers during cutting and grinding operations.
The report’s authors emphasized the need for national guidelines and better enforcement to protect workers from artificial stone silicosis. They highlighted the urgent need for early detection of cases and preventative measures to avoid a potential epidemic.
Since 2010, cases of artificial stone silicosis have been reported worldwide, but the UK confirmed its first cases in mid-2023. California has identified nearly 100 cases of silicosis among countertop workers, prompting the adoption of new regulations to safeguard workers.
Australia has already banned the use of artificial stone as of July 2024, aiming to eliminate the health risks associated with its production and installation.
In related editorials, Dr. Christopher Barber and researchers from Sheffield Teaching Hospitals NHS Foundation Trust drew parallels between artificial stone silicosis and historical occupational health crises, urging stricter regulations and enforcement to protect workers.
Experts are currently reviewing exposure limits for crystalline silica dust in the UK, with a focus on mitigating the risks associated with artificial stone worktops. Silicosis remains a significant concern for clinicians and researchers in the occupational health field.
