Industry Experience
ACZ Laboratories was founded to support the analytical environmental compliance needs of mining operations in the Western United States. Today ACZ provides analytical support to a broad base of clients throughout the United States as well as internationally. While ACZ’s main client base is still the mining industry, other industry experience and clients include: environmental consulting & engineering firms,oil, gas & energy, government organizations (federal, state, local and tribal), water treatment facilities, landfills, nutraceautical manufactures, and food/beverage importers.

In-Vitro Bioaccessibility
In-Vitro Bioaccessibility
Visit Page
In vitro bioaccessibility (IVBA) analysis measures the potential hazard from ingestion of metals in soil, dust or other solid waste material. The in vitro bioavailability or in vitro bioaccessibility methods were developed to replace the much more costly oral in vivo test which is conducted on live animals. EPA in vitro Method 1340 and EPA Method 9200.1-86 estimates the oral bioaccessibility of both lead and arsenic from soil by simulating the stomach fluid of a swine. The analysis is highly controlled in terms of the temperature as well as the pH of the fluid.
