“…The salinities of the seawater and NaCl solutions were determined using a conductivity meter (Lutron, Taipei, Taiwan), and were expressed as w/w (‰). The concentrations of SMX, SMM, and SDM in the samples were monitored using HPLC under a condition modified from a previous study (Lai and Hou, 2008). In brief, the HPLC consisted of a Hitachi L-7100 pump, an L-7200 autosampler, and an L-7455 diode array detector (Hitachi High Technologies, Tokyo, Japan).…”

“…The antibiotic concentrations were measured by conducting HPLC. The mobile phase consisted of a mixture (2:3 vol/vol) of methanol (Merck, Darmstadt, Germany) and 25 mM sodium phosphate (Shimakyu's Pure Chemical, Osaka, Japan) at a flow rate of 1.0 ml min −1 and a temperature of 40 • C. All detections of SMM were performed using UV absorption at 270 nm compared with authentic standards (Lai and Hou, 2008). …”

“…Abiotic photodegradation has been documented as a degradation pathway for several contaminants (Andreozzi et al 2003;Kim and Tanaka 2009;Lai and Hou 2008) though the effectiveness of photodegradation varies with specific compounds. Under UV irradiation (254 nm), acetaminophen and carbamazepine are more recalcitrant relative to sulfamethoxazole (Kim and Tanaka 2009).…”

The influence of six pharmaceuticals on freshwater sediment microbial growth incubated at different temperatures and UV exposures

Pharmaceutical compounds have been detected in freshwater for several decades. Once they enter the aquatic ecosystem, they may be transformed abiotically (i.e., photolysis) or biotically (i.e., microbial activity). To assess the influence of pharmaceuticals on microbial growth, basal salt media amended with seven pharmaceutical treatments (acetaminophen, caffeine, carbamazepine, cotinine, ibuprofen, sulfamethoxazole, and a no pharmaceutical control) were inoculated with stream sediment. The seven pharmaceutical treatments were then placed in five different culture environments that included both temperature treatments of 4, 25, 37°C and light treatments of continuous UV-A or UV-B exposure. Microbial growth in the basal salt media was quantified as absorbance (OD(550)) at 7, 14, 21, 31, and 48d following inoculation. Microbial growth was significantly influenced by pharmaceutical treatments (P < 0.01) and incubation treatments (P < 0.01). Colonial morphology of the microbial communities post-incubation identified selection of microbial and fungal species with exposure to caffeine, cotinine, and ibuprofen at 37°C; acetaminophen, caffeine, and cotinine at 25°C; and carbamazepine exposed to continuous UV-A. Bacillus and coccus cellular arrangements (1000X magnification) were consistently observed across incubation treatments for each pharmaceutical treatment although carbamazepine and ibuprofen exposures incubated at 25°C also selected spiral-shaped bacteria. These data indicate stream sediment microbial communities are influenced by pharmaceuticals though physiochemical characteristics of the environment may dictate microbial response.
