Abstract: <p>Microplastics, plastic particles less than 5 mm in diameter, are ubiquitous in the environment. This study estimated the abundance of microplastics (MP) in atmospheric deposition from four background monitoring stations in Muskoka-Haliburton, south-central Ontario, Canada and quantified the fate of microplastics to three background headwater lake catchments in Muskoka-Haliburton.… more

Name(s): Creator (cre): Spak, Justin George, Thesis advisor (ths): Aherne, Julian, Degree committee member (dgc): Koprivnjak, Jean-François, Degree committee member (dgc): Watmough, Shaun, Degree granting institution (dgg): Trent University
Abstract: <p>Maximum permitted SO2 emissions from an aluminum smelter in Kitimat, B.C., increased after modernization in 2015. An increase in acidic deposition can potentially acidify forest soils. Monitoring was conducted at two long-term soil monitoring plots at near (7 km) and far (41 km) sites downwind from the smelter. Change in soil properties was assessed between 2015 and 2018: for the near… more

Organic Matter and Total Mercury in Acid-Sensitive Lakes in Ireland

Name(s): Creator (cre): Nelson, Sarah A.M., Thesis advisor (ths): Aherne, Julian, Degree committee member (dgc): Hintelmann, Holger, Degree committee member (dgc): Koprivnjak, Jean-François, Degree granting institution (dgg): Trent University
Abstract: <p>The following study measured dissolved organic carbon (DOC) and total mercury (THg) concentrations in acid sensitive lakes in the Republic of Ireland. Sixty-eight upland lakes and 48 lowland lakes were sampled for DOC; the upland lakes were additionally sampled for THg. Spatial variability of DOC was explained by regional precipitation and soil organic matter. A subset of lakes was… more
