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).
Bupropion is an atypical antidepressant that&#039;s sold as Wellbutrin and Wellbutrin XL. Desipramine--Norpramin--is an older antidepressant in the tricyclic group of antidepressants.
