Report Date:

What do the daily graphs from air monitoring stations show? The New-Indy air monitors are stationary instruments that provide data that is averaged over 30-minute periods of time. The onsite instruments measure hydrogen sulfide (H2S) down to four-tenths parts per billion (0.4 ppb). The purpose of the stationary monitors is to provide quantitative information regarding H2S concentrations at New-Indy. The red line in the graphs is set at 70 ppb, which is the 14-day Minimum Risk Level (MRL) for H2S exposure developed by the Agency for Toxic Substances and Disease Registry (ATSDR). An MRL is defined as an estimate of daily exposure to a substance (H2S) that poses a minimal risk of adverse effects to humans over a specified duration of exposure (14 days).
