Explanation: TCLo - Lowest published toxic concentration
---For all of the 30,105 different chemical substances covered by the RTECS, there is given one or more actual measurements of toxicity. There are six types of measurement reported in the RTECS. Three of these are used only for the inhalation route of exposure: These are the lower limit of lethal concentration (LCLO), the concentration lethal to 50 percent of the exposed population (LC50), and the lower limit of toxic concentration (TCLO). For other administration routes, there may be available the lower limit of lethal dosage (LDLO), the dosage lethal to 50 percent of the treated population (LD50), or the lower limit of toxic dosage (TDLO). ---
