“…Methylparaben was found at concentrations ranging between 2.26 AE 0.49 and 40.4 AE 9.32 ng/g with a mean concentration of 14.2 ng/g. The mean concentrations of triclosan and triclocarban were 36.9 and 495 ng/g, which are similar to those in the Pearl River (Zhao et al, 2010). Moreover, these two compounds were predominant in the sediments with the detection frequencies of both 100% and the maximum concentrations of 403 AE 70.4 and 5649 AE 748 ng/g.…”

“…Thus, it is essential to understand their fate and risks in the environment. Various biocides have been detected in STP effluents, surface water and sediment (Aronson et al, 2012;Zhao et al, 2010). For example, the maximum reported levels in STP effluents were 443 ng/L for climbazole, 3700 ng/L for N,Ndiethyl-3-methylbenzamide (DEET), 112 ng/L for methylparaben, 2700 ng/L for triclosan and 342 ng/L for triclocarban (Blanco et al, 2009;Lee and Rasmussen, 2006;McAvoy et al, 2002;Wick et al, 2010;Zhao et al, 2010).…”

Mainly due to the discharge of domestic wastewater, biocides were also found in surface water and sediment, with the maximum levels of up to 5160 ng/L for triclosan in surface water and 2633 ng/g for triclocarban in sediment (Ramaswamy et al, 2011;Zhao et al, 2010).…”

“…This is linked to the high population in the two regions. It should be noted that high chemical concentrations in real aquatic environments are often found in tributaries rather than in the main streams Zhao et al 2010). With rapid economic development and increasing purchasing power in China, it should be expected to see increasing TCS contamination levels in the Chinese riverine environments if there is no improvement in wastewater treatment rate.…”

Since monitoring campaigns are often carried out only in summer and/or autumn (Wang et al 2011;Zhao et al 2010), it may create biased monitoring dataset.…”

This study aimed to investigate the emission and multimedia fate as well as potential risks of triclosan (TCS) in all of 58 basins in China. The results showed that the total usage of TCS in whole China was 100 t/year, and the discharge to the receiving environment was estimated to be 66.1 t/year. The predicted TCS concentrations by the level III fugacity model were within an order of magnitude of the reported measured concentrations. TCS (90.8 %) was discharged into the water compartment and 9.2 % to the soil compartment. The TCS concentration levels in east China were found generally higher than in west China. In addition, the input flux for TCS to seawater was largely attributed to the seasonal variations in advection flows. Preliminary risk assessment showed that medium to high ecological risks for TCS would be expected in the eastern part of China due to the high population density.

Pharmaceuticals and personal care products (PPCPs) have been detected widely in aquatic ecosystems, but little is known about their mechanisms of toxicity. We exposed adult fathead minnows (Pimephales promelas) for 48 h to triclocarban (1.4 µg/L), N,N-diethyl-meta-toluamide (DEET; 0.6 µg/L), or a mixture of PPCPs consisting of atenolol (1.5 µg/L), caffeine (0.25 µg/L), diphenhydramine (0.1 µg/L), gemfibrozil (1.5 µg/L), ibuprofen (0.4 µg/L), naproxen (1.6 µg/L), triclosan (2.3 µg/L), progesterone (0.2 µg/L), triclocarban (1.4 µg/L), and DEET (0.6 µg/L). Quantitative real-time polymerase chain reaction revealed an upregulation in vitellogenin (vtg) in livers of females and males exposed to triclocarban. Also, an upregulation of hepatic lipoprotein lipase (lpl) and a downregulation of androgen receptor (ar) and steroidogenic acute regulatory protein (star) were observed in testes. The group treated with DEET only showed a significant decrease in ar in females. In contrast, the PPCP mixture downregulated vtg in females and males and expression of estrogen receptor alpha (erα), star, and thyroid hormone receptor alpha 1 (thra1) in testes. The authors' results show that the molecular estrogenic effects of triclocarban are eliminated (males) or reversed (females) when dosed in conjunction with several other PPCP, once again demonstrating that results from single exposures could be vastly different from those observed with mixtures.
