Silica Dust

The disturbance of cement, concrete, and brick during the performance of demolition work, gutting work, and facade renovation and re-pointing work unavoidably results in the release of high levels of crystalline silica, which is an eye, nose, and throat irritant and an IARC category 1 carcinogen.

We provide a full range of indoor air quality testing services to evaluate levels of mold, bacteria, lead paint, asbestos, chemical vapors, tobacco smoke, formaldehyde, pesticides, PCB’s, crystalline silica, phthalates, heavy metals, mercury, aromatic hydrocarbons, and many other contaminants.

They were awesome! They really exert the effort to make sure the mold inspection is done correctly. I wanted to test the air on a condo that we were purchasing (because it had a strong damp smell when you walked in). Thanks, Angstrom & Team for helping me in time.

Angstrom tested the water at each of the sinks in our daycare center for lead. They helped us get our license from the New York City Department of Health. They arrived on time and got the job done without any hassles and provided all the paperwork that I needed. Thanks again! Philip Bleeker
