Can aluminum silicate be inhaled into the lungs?

Generally speaking, whether aluminum silicate can be inhaled into the lungs depends on its physical state. If aluminum silicate exists as dust, it may be inhaled; however, if it is in solid or liquid form, it typically will not be inhaled. In case of discomfort, prompt medical attention is recommended. Detailed analysis is as follows:

Aluminum silicate is a type of silicate commonly used as an industrial raw material and refractory material. During production, handling, or installation, thermal insulation materials containing aluminum silicate may generate large amounts of airborne dust particles and fibers. In its dust form, aluminum silicate may enter the lungs through inhalation. After being inhaled, some of these dust particles may be expelled from the body, but others may remain in the lungs. Long-term inhalation of aluminum silicate dust may cause respiratory discomfort, such as coughing and shortness of breath. In severe cases, it may lead to chronic bronchitis and pulmonary fibrosis.

In solid or liquid form, aluminum silicate does not easily produce inhalable particles, and therefore generally cannot enter the lungs via inhalation. Additionally, appropriate personal protective measures, such as wearing dust masks or respirators, can effectively reduce the risk of inhaling aluminum silicate.

When handling aluminum silicate, appropriate protective measures should be taken to minimize dust inhalation. Maintaining good ventilation in the work area and reducing dust accumulation are also important to protect respiratory health.
