Fugitive emissions can be a health concern during removal and disposal of mercury-contaminated material at remediation sites. Thus, remediation projects either indoors or outdoors often require on-site, real-time mercury air monitoring with a Tekran 2537. This assures permitted levels are not exceeded during waste processing and human exposure levels are below government regulated toxicity thresholds. Often multiple sites must be monitored continuously. The Tekran 1115 Multi-Port Sampler is the ideal tool for multiplexing the Tekran 2537 for real-time continuous on-site monitoring of mercury fugitive emissions.
