Project Description: Emerging contaminants (ECs) are of great concern to wastewater treatment utilities and the environment. ECs are used every day in our homes, on our farms, or by businesses and industry and include detergents, fragrances, prescription and nonprescription drugs, disinfectants, pesticides and others. Emerging contaminants such as antibiotics, nanoparticles, Bisphenol A (BPA) and endocrine disrupting compounds (EDCs) have drawn much attention for their adverse health and ecological effects. Antibiotics are not completely metabolized by humans/livestock and are commonly found in wastewater. Bisphenol A, one of the widely used EDCs, is of particular concern as it is suspected of estrogenic activity. The silver nanoparticles inhibit microbial growth in wastewater treatment. The attached publications discuss the removal of Bisphenol A, toxicity neutralization of silver nanoparticles, and the impact and removal of antibiotics in wastewater treatment systems.

Bisphenol A: BPA, an endocrine disrupter compound largely used in plastic and paper industry, ends up in aquatic systems via wastewater treatment plants among other sources. The identification and quantification of BPA in wastewater and wastewater sludge is of major interest to assess the endocrine activity of treated effluent discharged into the environment. BPA was measured in samples from the urban wastewater treatment plant using LC-MS/MS. The results showed that BPA was present in significant quantities in wastewater and in wastewater sludge. The treatment plant was efficient in removal of 76% of BPA from process stream, however, environmentally significant concentrations of BPA were still present in the treated effluent. Rheological study established the partitioning of BPA within the treatment plant. Higher BPA concentration was observed in primary and secondary sludge solids as compared to their liquid counterpart. Thus, BPA was present in significant concentrations in the WWTP and mostly partitioned in the sludge.

Nanoparticles: Nanosilver (Ag NPs) has been used broadly in nanotechnology-enhanced consumer products because of its strong antimicrobial properties. Silver nanoparticles released from these products will likely enter wastewater collection and treatment systems. The inhibitory effects of silver nanoparticles (Ag NPs) and other important Ag species on microbes were evaluated using extant respirometry and an automatic microtiter fluorescence assay. The results suggest that nitrifying bacteria are especially susceptible to inhibition by Ag NPs, and the accumulation of Ag NPs could have detrimental effects on the microorganisms in wastewater treatment. Sulfide appeared to be the only ligand to effectively reduce nanosilver toxicity. By adding a small aliquot of sulfide to stoichiometrically complex AgNPs, the nanosilver toxicity to nitrifying organisms was reduced by up to 80%.

Antibiotics: Antibiotics are used to maintain healthy livestock and promote weight gain in concentrated animal feed operations (CAFO). Antibiotics are rarely completely metabolized by livestock and, thus, are often present in livestock waste and waste treatment lagoons. The introduction of antibiotics into anaerobic lagoons, commonly used for swine waste treatment, has the potential for negative impacts on lagoon performance which relies on a consortium of microbes ranging from fermentative microorganisms to methanogens. To address this concern, the effects of eight common veterinary antibiotics on anaerobic activity were studied. Anaerobic microcosms, prepared from freshly collected lagoon slurries, were amended with individual antibiotics at 10 mg/L for the initial screening study and 1, 5, and 25 mg/L for the dose-response study. Monitored metabolic indicators included hydrogen, methane, and volatile fatty acid concentrations as well as chemical oxygen demand. The selected antibiotics significantly inhibited methane production relative to unamended controls, thus indicating that antibiotics at concentrations commonly found in swine lagoons can negatively impact anaerobic metabolism.
