“…The predicted TCS concentrations in fish for those basins with big cities such as Beijing (IDs: 13-15, 31.4-42.9 ng/g), .6 ng/g) were quite high. Unfortunately, there is no measured concentrations for fish from rivers in China, while in the USA, the measured concentrations in fish from rivers reported by Mottaleb et al (2009) ranged from 17 to 31 ng/g. Sensitivity analysis showed that TCS concentration in water compartment was more influenced by chemical emission and the area of the water phase.…”

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.

“…13,14 It was reported that bioaccumulation factors (BAFs) were found to be as high as 2100 for TCS and 2700 for TCC in algae. 15 Hence, the extensive detection of TCS and TCC has become a public concern as they may affect aquatic organisms such as algae, 16 crustacean 17 and sh.…”

Triclosan (TCS) and triclocarban (TCC) are two active ingredients widely used in many home and personal care products. Multimedia fate of TCS and TCC in the Dongjiang River basin, South China were addressed by the developed level III fugacity model based on their usage. Under the assumption of steady state, the concentrations in air, water, soil, sediment, suspended particulate matter (SPM) and fish as well as transfer flux across the interface between the compartments were simulated. The measured concentrations for the two compounds in water, SPM, and sediment from field monitoring campaigns were then compared to validate the model. The results showed that the model predicted reasonably accurate concentrations and the differences between the measured and modeled concentrations were all less than 0.7 log units. TCS and TCC had a tendency to distribute into the sediment phase, which accounted for more than 66.3% and 90.3% of the total masses, respectively. Wastewater discharge was the main source for the occurrence of the two compounds in the aquatic environment, while degradation was the primary process for the loss in the study area, followed by the advection export.Sensitivity analysis showed that the most influential parameters for the fate of the target chemicals were source term, degradation rates and adsorption coefficients. Monte Carlo simulation could well describe the modeling uncertainty and variability. Environmental impactPersonal care products are widely used in everyday life. Aer use, they are discharged into the receiving environments directly or indirectly. Their detection in the environment has become an increasing concern due to their potential impacts on the ecosystem. This paper developed a modied level III fugacity model to assess the multimedia fate of two personal care products (triclosan and triclocarban) in a river basin based on their usage data and evaluated the model by eld monitoring data in the Dongjiang River Basin. The modied steady state fugacity model can be used to evaluate contamination of personal care products at the basin scale based on their usage. This tool could be adopted by various decision-makers in the management of chemicals in river basins.

“…As the list of compounds found in field collected fish samples expands, the need to develop simultaneous screening methods for multiple classes of drug residues increases as well (Balmer et al 2004;Duedahl-Olesen et al 2005;Buser et al 2006;Rudel et al 2006;Mottaleb et al 2009). At present, the general approach employed for the analysis of multi-class pharmaceuticals in fish involves extraction of homogenized tissue with 1:1 mixture of 0.1 M acetic acid and methanol (Ramirez et al 2007), or acetonitrile combined with limited cleanup to back-extract lipid material followed by liquid chromatography-mass spectrometry (LC-MS) analysis (Smith et al 2009).…”
