Toxicology and Environmental Chemistry (TEC) monitors airborne contaminants in both spacecraft air and water. In-flight monitors are employed to provide real-time insight into the environmental conditions on ISS. Archival samples are collected and returned to Earth for full characterization of ISS air and water.<\/p>\n

Real-time in-flight air analytical instruments include the Air Quality Monitors (AQM), carbon dioxide (CO2<\/sub>\u00a0monitors), and a compound specific analyzer for combustion products (CSA-CP). Real-time in-flight water monitoring capabilities include the colorimetric water quality monitoring kit (CWQMK) and the ISS total organic carbon analyzer (TOCA).<\/p>\n

Post-flight analyses are performed on archival samples of spacecraft air and water obtained at specific times and locations during a mission. Air archival samples are collected using \u201cgrab sample containers\u201d (GSC) and formaldehyde badges. The U.S. and Russian water recovery systems on the ISS process atmospheric moisture (U.S. and Russian systems) and urine distillate (U.S. system only) into clean, potable water for the crew to use. \u00a0The Water Kit is utilized to collect archival samples of the potable water and are routinely returned to the ground to monitor the quality of the water produced by the systems. \u00a0Samples of condensate and wastewater are also collected and returned to check for the presence of contaminants that could break through the water recovery systems.\u00a0 \u00a0<\/p>\n
