Section Seven - Toxicological Data
This section expands of the information of the last section and, as such, is often included a part of the health hazards section. Here we find whether the product or any constituents are considered to be a carcinogen, mutagen, tumorigen, teratogen, birth or reproductive hazardous, what organs or body functions are targeted or if the hazard is systemic (that is it will affect any or all parts and/or functions of the body). Additionally we learn what amounts are determined to be lethal.
First, let me throw few more acronyms in your direction. All chemicals consider being carcinogens must be identified in a MSDS if present in the product in amount of 0.1 % or greater. A chemical is considered a carcinogen if:
The lethal dose 50% (LD50) and lethal concentration 50% (LC50) is the level of exposure that is has been determined that fifty per cent of those exposure at that concentration will die. Note, this not a pass/fail kind of thing, the living fifty percent are not okay. Depending on the toxin, the fifty per cent that survives may experience permanent health problems and disabilities. Even if they escape that fate, they will most likely have a harsh and painful recovery.
Both of these levels are given as the amount of toxin in milligram per kilogram of body weight (X mg/kg). The LC50 is sometimes stated as specific concentration for specific time period [most generally 4 hours] (X ppm/4H). Table 28 gives an estimate of what amounts of toxins are required for an average size person
