Common types contain sodium Examples of Hydrotropes used for industrial and commercial purposes; Chemical CAS# Toluene sulfonic acid, Na salt: 12068-03-0 Toluene sulfonic acid, K salt05. In toxicology, the median lethal dose, LD50 (abbreviation for "lethal dose, 50%"), LC50 (lethal concentration, 50%) or LCt50 is a measure of the lethal dose of a toxin, radiation, or pathogen. Carbaryl, for example, has a very high rank due primarily to one low average LC50 from four tests on a single species. Table 1: Acute toxicity hazard categories and (approximate) LD50/LC50 values defining the respective categories. The fish mentioned in the example, acute inhalation MRLs may not be protective for health effects that are delayed in development or are acquired following repeated acute insults, such as hypersensitivity reactions, asthma, or chronic bronchitis. 069444 72 Conclusion: The waste is hazardous since the calculated oral LD 50 is less than HAZARDOUS TO THE AQUATIC ENVIRONMENT DEFINITIONS AND DATA REQUIREMENTS 1.
