A dose of 0.5 milligrams of melatonin has been taken under the tongue for six days. For seizure disorders, doses of melatonin taken by mouth were 3-10 milligrams daily for 2-4 weeks to three months. For sleep (general), doses of melatonin taken by mouth were 0.3-10 milligrams.
The degradation of the synthetic, amphoteric surfactant, cocamidopropyl betaine (CAPB) and its toxicity to the marine macroalga, Ulva lactuca, has been evaluated using several different physiological test end-points over different periods of exposure up to 120 h.ell membrane damage, estimated from measurements of ion leakage, was detected only at a concentration of 40 mg l(-1) after 48 h of exposure to CAPB but by 120 h damage was evident at all measured concentrations above 10 mg l(-1).
Best Answer: From-http://www.tennesseeturfgrassweeds.org/a... Monosodium methanearsonate (MSMA) is a commonly used herbicide in warm-season climates.Since the 1960s, this product has been used to manage infestations of various crabgrass species (Digitaria spp.), as well as goosegrass (Eleusine indica) and dallisgrass (Paspalum dilatatum) in warm-season turf.n its organic form, arsenic is relatively nontoxic. For example, the herbicide MSMA is far less toxic than aspirin1,2. However, in an inorganic state, arsenic can be highly toxic. It is important to note that MSMA only contains organic arsenic.
