Optimisation of the analysis of anti-influenza drugs in wastewater and surface water
<div><p>We optimised the simultaneous analysis of four analytes, namely three anti-influenza drugs (oseltamivir (OS), zanamivir (ZAN) and amantadine (AMN)) and one metabolite of OS (oseltamivir carboxylate (OC)), in sewage treatment plant (STP) influent and effluent by verifying the types and conditions of solid phase extraction (SPE) appropriate for LC-MS/MS analysis. In summary, these target analytes were extracted from aqueous samples (30–50 mL) by using strong cation-exchange SPE cartridges (500 mg adsorbent) under acidic conditions (pH 3–4). After washing of the cartridges with acidified water (pH 3.0, 3 mL) and methanol (3 mL), the analytes were eluted with a mixed solvent (2 mL) of 10% (v/v) triethylamine in a 1:1 (v/v) mixture of acetone and water. Application of this technique to the target compounds should yield a comprehensive understanding of the occurrence and fate of anti-influenza drugs in the water environment.</p></div
Modeling the Photochemical Attenuation of Down-the-Drain Chemicals during River Transport by Stochastic Methods and Field Measurements of Pharmaceuticals and Personal Care Products
Existing stochastic models for predicting
concentrations of down-the-drain
chemicals in aquatic environments do not account for the diurnal variation
of direct photolysis by sunlight, despite its being an important factor
in natural attenuation. To overcome this limitation, we developed
a stochastic model incorporating temporal variations in direct photolysis.
To verify the model, we measured 57 pharmaceuticals and personal care
products (PPCPs) in a 7.6-km stretch of an urban river, and determined
their physical and biological properties in laboratory experiments.
During transport along the river, 8 PPCPs, including ketoprofen and
azithromycin, were attenuated by >20%, mainly owing to direct photolysis
and adsorption to sediments. The photolabile PPCPs attenuated significantly
in the daytime but persisted in the nighttime. The observations were
similar to the values predicted by the photolysis model for the photolabile
PPCPs (i.e., ketoprofen, diclofenac and furosemide) but not by the
existing model. The stochastic model developed in this study was suggested
to be a novel and useful stochastic model for evaluating direct photolysis
of down-the-drain chemicals, which occurs during the river transport
Synchronous Dynamics of Observed and Predicted Values of Anti-influenza drugs in Environmental Waters during a Seasonal Influenza Outbreak
Time-dependent
dynamics in the concentrations of four anti-influenza
drugs (oseltamivir, oseltamivir carboxylate, zanamivir, and amantadine)
in environmental waters collected from the Yodo River basin, Japan,
were monitored for the first time over a 1 year period (July 2010
to June 2011). The clear, convex dynamic profiles of oseltamivir,
oseltamivir carboxylate, and zanamivir during a 3 month seasonal influenza
outbreak (January to March 2011) were synchronized well with that
of the numbers of influenza patients treated with the drugs. The highest
levels in sewage treatment plants (STPs) and river waters were, respectively,
177 and 60 ng/L (oseltamivir), 827 and 288 ng/L (oseltamivir carboxylate),
and 30 and 15 ng/L (zanamivir). Fixed levels of amantadine were detectable
year-round (100–200 ng/L in the STPs and 10–30 ng/L
in river waters). The predicted convex profiles of oseltamivir, oseltamivir
carboxylate, and zanamivir in both STPs and river waters were significantly
correlated (0.714 < <i>R</i> < 0.932) with the observed
values. The profiles were predicted successfully by simple mathematical
principles, taking the number of influenza patients, quantities of
Tamiflu and Relenza used, dilution by drainwaters passing through
STPs, removal rates at STPs, dilution rates in river effluents, and
attenuation rates in rivers into consideration
Ozone treatment process for the removal of pharmaceuticals and personal care products in wastewater
<p>This study investigated the degradability of pharmaceuticals and personal care products (PPCPs) by ozonation for the treatment of secondary effluent of a municipal wastewater treatment plant. A set of experiments were conducted in a laboratory using a pilot-scale process consisting of three flow-through reactors in series, by varying the ozone dose (1–9 mg L<sup>−1</sup>), the hydraulic retention time (5–15 min), and the concentration of ozone injected into the reactors (14–42 mg L<sup>−1</sup>). Thirty-seven PPCPs were detected in the secondary effluent, which belongs to the use categories of antibiotics, analgesics, antiarrhythmic agents, anticonvulsants, vasodilators, lipid modifying agents, anti-itch drugs, anti-psychotic drugs, insect repellents, bronchodilators, diuretics, peptic ulcer drugs, NMDA receptor antagonists, antifungal drugs, antimicrobial drugs, and antineoplastic agents. These PPCPs were broadly classified into five groups ranging from “sensitive” to ozone (O<sub>3</sub>) or “unstable” in the ozonation process, to the group of “insensitive” to O<sub>3</sub> or “very stable” in the ozonation process. These groups are based on the PPCP concentrations after the ozone treatment and their limit of detection (LOD). Furthermore, this study examined comparatively the effects of the ozone dose, the retention (reaction) time, and the concentration of O<sub>3</sub> supplied to the reactors on the degradability of the PPCPs.</p
