Study lakes were visited by our multi-university research team in early June 2016. Sediment cores were collected from each lake’s deep, central basin using a standard approach. In a laboratory, sediments can be dated to provide age estimates (e.g. 1960 AD ± 5 years) and establish a detailed timeline of environmental changes, including the deposition and levels of contaminants such as DDT. Undergraduate students from Mount Allison and University of New Brunswick (Saint John) pictured here at Upsalquitch Lake were active contributors to this project, including both field and laboratory work. https://images.squarespace-cdn.com/content/v1/6294dd556465366879ef220b/1653923176430-JLB0IS5JQGPV3NOKHOLY/Bosmina.jpg Media Archive Sedimentary remains of Bosmina. Remains of the small-bodied aquatic organism Bosmina are very common in lake sediments and one of the most frequent zooplankton remains found. Bosmina live in the open-water area of lakes where they consume algae. Studies indicate Bosmina populations often increase relative to other zooplankton when lakes experience stressors, such as pollution, or other environmental changes such as the indirect effects of climate change. Pictured here is a headshield (right) and carapace (left) of Bosmina magnified at 400x. https://images.squarespace-cdn.com/content/v1/6294dd556465366879ef220b/1653923176393-5E9XCM0E4HPF1CHG53N1/DaphniaPAC.jpg Media Archive Sedimentary remains of Daphnia. Postabdominal claws of Daphnia are well-preserved in lake sediments. Daphnia are key members of a lake’s zooplankton community. In several of our study lakes, Daphnia have decreased substantially in relative abundance since the mid-20th century, coincident with the widespread use of DDT in north-central New Brunswick, Canada. Studies demonstrate that loss of daphniids in some lake ecosystems result in greater algae populations and/or less food available to predators that consume Daphnia, such as small fish. https://images.squarespace-cdn.com/content/v1/6294dd556465366879ef220b/1653923176365-R0U4YN4VCUZ5MLDQL9DH/DaphniaEdit.jpg Media Archive Daphnia. An image of the aquatic organism Daphnia, commonly known as a water flea. They are often numerous in lakes and important grazers of algae, and are eaten by small fish, waterfowl, and large invertebrates. Daphnia are sensitive to their aquatic environment, including DDT levels and other contaminants. Daphniids are used worldwide in toxicology and ecology studies, and are often considered a keystone aquatic species. The postabdominal claw (indicated by the arrow) of Daphnia are preserved in lake sediments and useful to their identification.

Once a lake sediment core is collected it is brought to shore. Each core is photographed, measured, and sectioned at 0.5-cm throughout. Each 0.5-cm sediment interval is carefully handled to minimize contamination and placed in labelled storage bags for transport to and storage in the laboratory. Each interval represents a distinct time period captured within each sediment archive. Typically, intervals near the top of the core (younger material) capture fewer months or years than intervals near the base of the core (older material). Pictured here is a researcher sectioning a core from California Lake. . https://images.squarespace-cdn.com/content/v1/6294dd556465366879ef220b/1653923176380-MOMY6CYUY7P8FJDDT5R2/Paul+at+SIN.jpg Media Archive Sediments from Sinclair Lake. Sediments accumulate in an orderly fashion in lakes, making them valuable archives of past environmental conditions. They are composed of materials carried into the lake by water or wind (e.g. DDT, pollen, soil), as well as materials produced within the lake (e.g. aquatic organisms). At our study lakes, we studied the uppermost ~15 to 22 cm of sediment, about half of the core length that was collected. These uppermost sediments represent about 100 years of environmental history at each study lake and capture the time periods before, during, and after use of DDT in the mid-20th century. https://images.squarespace-cdn.com/content/v1/6294dd556465366879ef220b/1653923176333-9VZBR3SNQ9QXPUIICNB3/UP+Lake.JPG Media Archive Study lakes. Five remote lakes from north-central New Brunswick, Canada were studied. Study lakes have no major inflowing streams and are located within conifer-dominated forests. Access to each lake was possible with a 4-wheel drive vehicle on rough gravel roads.

Approximately 5.7 million kg of DDT was applied to ~50% of New Brunswick between 1952 and 1968. The total amount of DDT applied to the forests surrounding five of the study lakes ranged from 0.5 to 3 kg/ha.

All 42 fish measured for DDTs were humanely collected and killed following methods and permits approved by the Animal Care Committee at Mount Allison University and the Department of Fisheries and Oceans. Brook Trout are a sentinel species and their health indicates the overall health of the ecosystem.
