Microbial Repopulation Following In Situ Star Remediation, Gavin Overbeeke
Microbial Repopulation Following In Situ Star Remediation, Gavin Overbeeke
Electronic Thesis and Dissertation Repository
In situ STAR (Self-sustaining Treatment for Active Remediation) is an emerging remediation technology which uses smouldering combustion to destroy nonaqueous phase liquid (NAPL) contamination in the subsurface. Since STAR smouldering travels through contaminated soils slowly (~0.5 to 5 m/day) and subjects them to high temperatures (400–1000°C), it is expected that this technology will thoroughly dry and sterilize the zones which it treats. Further, soils surrounding the treatment zone which are not smouldered will be heated, although not smouldered, by virtue of their proximity to STAR, impacting microbial communities within them. Therefore, the objectives of this work are to quantify the …
Investigating The Suitability Of The Crayfish Metabolome As A Bioindicator Of Stream Conditions, Natalie M. Izral
Investigating The Suitability Of The Crayfish Metabolome As A Bioindicator Of Stream Conditions, Natalie M. Izral
Electronic Thesis and Dissertation Repository
The suitability of the crayfish metabolome as a bioindicator of stream conditions was investigated because there is a need for fast responding, sensitive, diagnostic, and ecologically relevant bioindicators. A laboratory study assessed Procambarus clarkii metabolome sensitivity to six different treatments of food or DO stress. A field study in subcatchments of the Red River Valley, Manitoba, Canada assessed the effects of land-use type (reference, agriculture, wastewater effluent) on the Orconectes virilis metabolome. Crayfish were sacrificed, and hepatopancreas, gill, and tail tissues were dissected. Analyses found the metabolome was sensitive enough to potentially diagnose food and DO stress in P. clarkii …
Exposure To Environmental Contaminants And Stress As Determinants Of Health In Three Communities: Walpole Island And Attawapiskat First Nations And Naivasha, Kenya, Deirdre Phaedra Henley
Exposure To Environmental Contaminants And Stress As Determinants Of Health In Three Communities: Walpole Island And Attawapiskat First Nations And Naivasha, Kenya, Deirdre Phaedra Henley
Electronic Thesis and Dissertation Repository
This project is an interdisciplinary, community-based, participatory Ecosystem Health investigation with two First Nations in Canada, one located in the far south (Walpole Island; WIFN) and one in the far north (Attawapiskat; AttFN), and a large Kenyan community surrounding Lake Naivasha. The increased human health risks from exposure to three classes of environmental contaminants, persistent organic pollutants (POPs), pesticides and metals, and fear from such exposures are pressing concerns in each setting. Sensitive analysis of 15 metals in hair, six metals and 91 POPs in whole blood or serum of WIFN and AttFN volunteers has been conducted. Whole blood samples …
Cadmium Accumulation And Distribution In Lettuce And Barley, Fardausi Akhter
Cadmium Accumulation And Distribution In Lettuce And Barley, Fardausi Akhter
Electronic Thesis and Dissertation Repository
Cadmium (Cd) is a non-essential trace element and its environmental concentrations are increasing due to human activities. Edible plants can accumulate high concentrations of Cd, which could be toxic to humans. Understanding how and where Cd is stored in plants is important for ensuring lower concentration of Cd in the food. In this thesis, the accumulation and distribution of Cd in three agricultural plants, namely lettuce (Lactuca sativa L.), barley (Hordeum vulgare L.) and radish (Raphanus sativus L.), were investigated with a focus on the potential mechanisms involved in the localization of Cd in the root. The …
