Artificial Stone Countertops Linked to Severe Lung Disease Crisis

Occupational health specialists Dr. Robert Harrison and Dr. David Michaels report that the fabrication of artificial stone—often marketed as quartz—is fueling a public health crisis. These materials contain at least 90% crystalline silica, which releases nano-sized particles during cutting and polishing. Inhaling this dust leads to silicosis, a progressive condition that has already claimed at least 30 lives in California alone between 2019 and 2026. More than 550 workers in the state have been diagnosed with the disease, with at least 100 individuals requiring lung transplants.

Brayton Purcell LLP, a law firm currently representing over 700 affected clients, is amplifying these findings to bridge the gap between consumer demand and workplace reality. According to partner James Nevin, many homeowners remain unaware of the human toll behind their kitchen renovations. While retailers like Costco, Home Depot, and Lowe's contract local shops for fabrication, researchers maintain that over 100 peer-reviewed studies suggest the material cannot be processed safely by humans, regardless of existing protective protocols. As legal claims mount across the United States, the focus remains on the disconnect between industry safety standards and the clinical evidence of widespread respiratory failure.
