Age Determination and Growth of Rainbow Darter (Etheostoma caeruleum) in the Grand River, Ontario
(University of Waterloo, 2016-05-31)The accurate determination and validation of age is an important tool in fisheries management. Age profiles allow insight into population dynamics, mortality rates and growth rates, which are important factors in many ... -
Analysis of Temporal Changes in Estrogenic Compounds Released from Municipal Wastewater Treatment Plants
(University of Waterloo, 2019-09-26)Wastewater treatment plants (WWTPs) are traditionally designed to target the removal of contaminants such as total suspended solids, phosphorous, biological oxygen demand, and ammonia. Recent changes to the Federal ... -
The Apparent Partitioning Behaviour of SARS-CoV-2 RNA in Municipal Wastewater
(University of Waterloo, 2023-04-10)The use of wastewater-based surveillance (WBS) has experienced rapid expansion and development since the onset of the coronavirus disease (COVID-19) pandemic that is caused by the virus severe acute respiratory syndrome ... -
Assessing the Sampling Design of the Community Aquatic Monitoring Program (CAMP)
(University of Waterloo, 2017-08-16)The Community Aquatic Monitoring Program (CAMP) is a community based monitoring program that involves local stakeholders to monitor estuaries and bays in the southern Gulf of St. Lawrence (sGSL). Implemented in 2003, CAMP ... -
Assessment of remote Patagonian riverine fish using environmental DNA
(University of Waterloo, 2022-04-26)Freshwater systems and fish communities face many anthropogenic threats such as climate change, pollution, and invasive species, causing a rapid loss of biodiversity. To protect freshwater fish basic knowledge of their ... -
Biological responses in rainbow darter (Etheostoma caeruleum) to changes in municipal wastewater quality in the Grand River
(University of Waterloo, 2017-09-27)This thesis is a synthesis of studies that explore the effects of urbanization on a small-bodied fish species, rainbow darter (Etheostoma caeruleum), in the central Grand River (Ontario, Canada) over time. This watershed ... -
Does intersex matter? A case study of rainbow darter in the Grand River
(University of Waterloo, 2016-12-21)Endocrine disrupting compounds (EDCs) are present in the environment and can have negative effects on the health of wildlife. Aquatic organisms residing near the outfalls of municipal wastewater effluent (MWWE) are chronically ... -
Evaluating contaminants of emerging concern in municipal wastewater effluents
(University of Waterloo, 2016-10-25)Municipal wastewater treatment plant effluent (MWWE) is a complex matrix that acts as a significant source of contaminants to aquatic receiving environments. Contaminants of emerging concern (CECs) are known to affect ... -
Evaluation of Gold Nanoparticle-Doxorubicin Conjugates for their Use in Drug Delivery
(University of Waterloo, 2016-08-24)Since the seminal work on spherical nucleic acids (SNAs) by Mirkin and co-workers in 1996, substantial research investment has been devoted to gold nanoparticle (AuNP)-based biotechnology advancement. AuNPs have several ... -
Fate and Transport of Synthetic DNA in Surface Water
(University of Waterloo, 2021-09-29)Unlike conventional salt or dye tracers, artificial/synthetic DNA hydrologic tracers are essentially non-toxic and several can be used simultaneously. These features have implications for DNA to be used to better understand ... -
Growth of rainbow darter (Etheostoma caeruleum) in the Grand River watershed
(University of Waterloo, 2020-11-27)Assessment of growth is an important tool in fisheries assessment and management and provides valuable insight into biological responses to stressors in biomonitoring programs. A small-bodied fish species, rainbow darter ... -
Indications of benthic macroinvertebrate assemblage recovery following wastewater treatment upgrades in the central Grand River
(University of Waterloo, 2022-09-28)Treated effluent from wastewater treatment plants (WWTPs) can be a source of substantial nutrient and contaminant loading, altering water chemistry and ecological conditions in receiving waters. To meet new regulations and ... -
Modeling the emission, transport, and fate of key micropollutants and their treatment using novel titanium dioxide nanomaterials
(University of Waterloo, 2018-01-31)Endocrine disruptive effects in fish have been observed in many watersheds worldwide. The presence of intersex (ova-testes) in particular is well-documented in the Grand River watershed in southern Ontario, and is associated ... -
Movement of mature and early life stages of the Grand River walleye (Sander vitreus) population in Lake Erie's eastern basin
(University of Waterloo, 2020-09-04)Lake Erie’s commercial and recreational walleye fishery is the largest of the Great Lakes, requiring effective management to maintain a sustainable and complex fishery. Lake Erie’s walleye fishery is composed of multiple ... -
Nanomaterials in Water Remediation: Functionalization and Applications for Pharmaceutical Removal in Municipal Wastewater Effluent
(University of Waterloo, 2019-09-10)With an increasing population, there is a higher pressure on natural resources including water. Increased water consumption, altered hydrology and pollution, threaten the sustainability of aquatic ecosystems and water ... -
