Uptake of some selected aquatic pollutants in semipermeable membrane devices (SPMDs) and the polar organic chemical integrative sampler (POCIS)

摘要: The uptake characteristics of semipermeable membrane devices (SPMDs) and polar organic chemical integrative samplers (POCISs) were examined for mono, di tributyltin, triphenyltin, pyrene, benzo[a]pyrene, 4-tert-butylphenol, 4-n-nonylphenol, PCBs 77 153, PBDE 47, lindane, triclosan DDT. Exposure in a flow through system continued 28 days with removed every 7 order to study the relevant kinetics. Uptake remained linear POCISs sampling rates (Rs) up 0.2 L d−1. For SPMDs varied from approaching equilibrium Rs values 14 out 9 results could be explained by an empirical model (nonylphenol lindane exceptions). None four organo-tin compounds studied detected only tributyltin was accumulated significantly SPMDs. establishment these allows calculation time weighted water concentrations several important contaminants. Using presented methods, exposure conditions, theoretical detection limits selected between 11–68 pg L−1, which is well below environment quality standard proposed those that are included European Water Framework Directive.
