“…Particularly, the concentration of DOC was high in all the detected samples although the detection frequency was much lower than that of most other antibiotics. The concentrations of the veterinary antibiotics in the estuarine sediments of the Bohai Sea are comparable to results reported from other study areas (Lalumera et al, 2004;Le and Munekage, 2004) as shown in Table 3. The average concentrations of OTC, TC and EFC were generally higher in the present study area than most other study areas.…”

Veterinary antibiotics are emerging contaminants of concern. A total of 139 samples comprising 104 marine sediments and 35 estuarine sediments were collected from the Bohai Sea area and analyzed for seventeen antibiotics. The results reveal that the presence and concentration of antibiotics were generally higher in the estuaries than in the sea. The highest antibiotic concentration, 4695 μg kg −1 of oxytetracycline, occurred in the estuarine sediment from Ziya New River. Bohai Bay and Laizhou Bay and the surrounding estuaries had higher concentrations of antibiotics. However, low levels of antibiotics detected were detected in Liaodong Bay in contrast to the high concentrations present in the surrounding estuaries. Spatial heterogeneity and principal component analysis suggest a large impact of terrestrial sources of the antibiotics contaminating the Bohai Sea. Risk quotients indicate that current levels of norfloxacin and oxytetracycline might be potentially hazardous to sensitive biota both in the Bohai Sea and in its surrounding estuaries.

“…Apart from the potential for direct soil contamination, there is also the risk of run-off with heavy rain, thus potentially contaminating both the surround-ing surface and groundwater [42][43][44]. Other example of an anthropogenic activity is aquaculture, whose pharmaceuticals employed, as well as their metabolites and degradation prod-ucts, are directly discharged into surface waters [45,46]. Another important source of environmental contamination by pharma-ceuticals is the effluents of pharmaceutical production facilities [47][48][49].…”

Pharmaceuticals are biologically active and persistent substances which have been recognized as a con-tinuing threat to environmental stability. Chronic ecotoxicity data as well as information on the current distribution levels in different environmental compartments continue to be sparse and are focused on those therapeutic classes that are more frequently prescribed and consumed. Nevertheless, they indicate the negative impact that these chemical contaminants may have on living organisms, ecosystems and ultimately, public health. This article reviews the different contamination sources as well as fate and both acute and chronic effects on nontarget organisms. An extensive review of existing data in the form of tables, encompassing many therapeutic classes is presented.Keywords: Pharmaceuticals, Sources, Environmental fate, Ecotoxicological effects

“…[10−13] In a small Mediterranean stream (Arc River, Southern France), the concentrations of macrolide antibiotics were determined even at high µg/L levels in river water during the winter season. [14] In the water samples from shrimp ponds, Le and Munekage [15] found maximum concentrations of trimethoprim, sulfamethoxazole, norfloxacin and oxolinic acid more than 1 mg/L. Seasonal variations for antibiotics in surface water have been observed and attributed to various factors such as temperature and flow condition.…”

The distribution and occurrence of 15 antibiotics in surface water of the Pearl River System (Liuxi River, Shijing River and Zhujiang River) and effluents of four wastewater treatment plants (WWTPs) were investigated in two sampling events representing wet season and dry season by using rapid resolution liquid chromatography-electrospray tandem mass spectrometry (RRLC-MS/MS) in positive ionization mode. Only eight antibiotics (sulfadiazine, sulfapyridine, sulfamethazine, sulfamethoxazole, trimethoprim, roxithromycin, erythromycin-H 2 O and norfloxacin) were detected in the water samples of the three rivers and the effluents. The detection frequencies and levels of antibiotics in the dry season were higher than those in the wet season. This could be attributed to the dilution effects in the wet season and relatively lower temperature in the dry season under which antibiotics could persist for a longer period. The levels of the detected antibiotics in different sites are generally in a decreasing order as follows: Shijing River ≥WWTP effluent ≥Zhujiang River ≥ Liuxi River. Risk assessment based on the calculated risk quotients showed that only erythromycin-H 2 O and roxithromycin detected in the Pearl Rivers might have adverse effects on aquatic organisms.
