Interactions Between Dibutyl Phthalate and Aquatic Organisms

Tetrahymena pyriformis Phagocytic Activity Test for Rapid Toxicity Assessment of Aquatic Micropollutants

“…The T. pyriformis phagocytic activity test proved to be sensitive to the tested model substances in the 0.005─0.1 µg/L concentration range. The EC 50 values of the D. magna immobilization test were found at mg/L concentration level [19,38,41,43,45,48] [39,44,46,49], it can be concluded, that the phagocytic activity test exhibited higher sensitivity (at lower concentration levels) to the tested substances compared to the other above mentioned well established acute ecotoxicity tests. (Table 4).…”

Effects of three phthalate esters on the life-table demography of freshwater rotifer Brachionus calyciflorus Pallas

“…The population growth of rotifers decreased under the stress of all the tested pollutants with estrogenic activity for vertebrates Sarma 1986, 1990;Fernandez-Casalderrey et al 1991Ferrando et al 1993;Janssen et al 1994;Snell and Carmona 1995;Gallardo et al 1997;Preston et al 2000;Preston and Snell 2001;Radix et al 2002;MarirazPerez et al 2004;Xi and Feng 2004;Marcial et al 2005;Chu et al 2005), except micromolar concentrations of gamma-aminobutyric acid, growth hormone, human chorionic gonadotropin and 5-hydroxytryptamine, which increased the population growth of B. plicatilis, aldrin and DBP, which increased the intrinsic rate of population increase of B. calyciflorus and D. magna (Gallardo et al 1997;Huang et al 1999Huang et al , 2007, and juvenile hormone, 20-hydroxyecdysone and tri-iodothyronine, which had no effect on population growth (Gallardo et al 1997). In the present study, BBP at 50 and 500 lg l -1 increased the intrinsic rate of population increase of the rotifers, but the reverse was also true for DBP at 50 lg l -1 .…”

“…As a consequence of chronic toxicant stress, a reduction in net reproductive rate was observed in B. patulus, B. calyciflorus, B. plicatilis and D. magna (Rao and Sarma 1986;Fernandez-Casalderrey et al 1991Janssen et al 1994;Huang et al 1999;Xi and Hu 2003;Chu et al 2005;Xu et al 2005). However, sublethal concentrations of aldrin, chlordecone and DBP increased the net reproductive rates of B. calyciflorus and D. magna Zha et al 2007).…”

“…In recent years, they have been shown to have potential for endocrine disrupting effects on vertebrates and humans (OSPAR Commission 2006). Although some information on the acute and chronic toxicities of these three PAEs to aquatic microorganisms, algae, invertebrates and fish is available (Stamples et al 1997;Huang et al 1998Huang et al , 1999Ministry of Environment, Government of Japan 2002Bradlee and Thomas 2003;Norman et al 2007), relatively little is known about their chronic toxicities on rotifers .…”

Using an Attapulgite-Activated Carbon Composite Ceramisite Biofilter to Remove Dibutyl Phthalate from Source Water

“…In fact, DBP has been listed as an environmental priority pollutant by the United States Environmental Protection Agency, the European Environment Agency, and the Ministry of Environmental Protection of China [7]. In addition, the testing work of this kind of trace micropollutant in water works is not regular [4]. Therefore, a simple, effective, and adaptable changed DBP removal process from drinking source water is urgently needed.…”
