While artificial stone—commonly known as engineered stone or quartz—enhances the aesthetic appeal of kitchens, leading medical experts warn that it poses a significant health risk to workers engaged in its cutting and polishing.
Artificial stones are composed of crushed rocks bonded with resins, making them popular for their durability and lack of natural imperfections. However, a recent study published in the journal Thorax highlights a troubling trend: the rise of a severe and rapidly progressive form of silicosis, termed “artificial stone silicosis.” This condition is largely attributed to the high silica content (over 90%) of artificial stone compared to marble (3%) and granite (30%), as well as the fine dust produced during cutting.
The study indicates that workers often cut and polish these stones “dry,” using tools like angle grinders without water to minimize dust. This practice significantly increases the volume of hazardous silica dust released.
The Thorax study documents eight cases of workers, averaging 34 years old, who developed serious lung diseases while working with artificial stones in the UK. Among them, two required evaluations for lung transplants, three were assessed for autoimmune diseases, and two suffered from lung infections caused by non-tuberculous mycobacteria.
Amid growing international concerns over silica dust exposure, the UK is currently reviewing its exposure limits. Dr. J.C. Suri, former head of pulmonary medicine at Safdarjung Hospital, noted that inhaling silica can lead to lung scarring and increase susceptibility to tuberculosis. He highlighted the severe health effects observed in construction workers at his hospital, varying based on exposure duration.
Dr. Suri emphasized the dangers of fine silica dust released during the cutting and polishing of artificial stones. While eliminating the use of these materials may be challenging, he advocates for enhanced safety measures for workers involved in their processing. Recommendations include using nasal filters and implementing technology to reduce silica dust exposure, thereby mitigating the risk of silicosis.
