Toxicity
Much of vermiculite toxicity is associated with asbestos. According to the Centers For Disease Control, prolonged exposure to asbestos can lead to asbestosis, an inflammation of the chest cavity also known as pleurisy. It can also lead to lung cancer, recurrent pneumonia and an asbestos-related cancer known as malignant mesothelioma. The average time frame for asbestos-related lung conditions to occur is 20 to 40 years after the first exposure. By itself, vermiculite is not considered toxic, but the mineral does produce a dust that can cause asthma and allergies.
