Acute and chronic toxicity of neonicotinoid and butenolide insecticides to the freshwater amphipod, Hyalella azteca

Neonicotinoids are the most widely used insecticides in the world. They are preferentially toxic to insects while displaying a low toxicity toward vertebrates, and this selective toxicity has resulted in the rapid and ubiquitous use of these compounds. However, neonicotinoids have been detected in agricultural surface waters and are known to cause adverse effects in non-target aquatic organisms. A wide range of toxicity has been reported for aquatic crustaceans, but most of the studies focus on the acute effects of imidacloprid, and few data are available regarding chronic effects of other neonicotinoids or neonicotinoid replacements (e.g., butenolides). The objective of this study was to assess the acute and chronic toxicity of six neonicotinoids (imidacloprid, thiamethoxam, acetamiprid, clothianidin, thiacloprid, and dinotefuran) and one butenolide (flupyradifurone) to the freshwater amphipod Hyalella azteca. Chronic (28-day), water-only, static-renewal tests were conducted. Survival was assessed weekly, and growth was measured at the end of the exposure. The concentrations of imidacloprid and clothianidin reported for North American surface waters fall within the effect ranges observed in this study, indicating the potential for these compounds to cause adverse effects to indigenous populations of H. azteca.

Persistent organic pollutants (POPs) in ringed seals (Phoca hispida) across the Canadian Arctic

Ringed seals (Phoca hispida) have been used as bioindicator species of environmental contamination in Canada since the 1970s. In the present study, seals were harvested during subsistence hunts in four regions of the Canadian Arctic: Beaufort Sea, Arctic Archipelago, Hudson Bay, and coastal Labrador. An extensive suite of persistent organic pollutants (POPs) was determined in seal blubber collected for multiple years between 1972 and 2016. Results from this long-term study indicate geographical differences in the contaminant concentrations in seals and the significant general decrease of most POPs, including polychlorinated biphenyls (PCBs), dichlorodiphenyltrichloroethane (DDT) and related compounds, chlordanes (CHL), and hexachlorocyclohexanes (HCH) over time in ringed seals. Overall, results suggest that North American and international regulations have led to the long-term reduction of most POPs in Canadian Arctic ringed seals by reducing emissions from primary sources. However, other sources of legacy compounds (e.g., environmental reservoirs) as well changes in food web composition and structure in relation to climate changes could also be influencing the very slow rates of decline, or stable levels, of contaminants found in seals at some sites.

The Northern Contaminants Program (NCP, http://www.science.gc.ca/eic/site/063.nsf/eng/h_7A463DBA.html) was established in 1991 in response to concerns about human exposure to elevated levels of contaminants in wildlife species that are important to the traditional diets of northern Aboriginal peoples. Early studies found a wide variety of substances, many of which had no Arctic or Canadian sources, but which were, nevertheless, reaching unexpectedly high levels in the Arctic ecosystem.

The Canadian Cryospheric Information Network (CCIN, https://www.ccin.ca/) and the Polar Data Catalogue (PDC, https://polardata.ca/) have been developed over the past two decades through collaborative partnerships between the University of Waterloo and numerous government, university, and private organizations to provide the data and information management infrastructure for the Canadian cryospheric community. The PDC is one of Canada’s primary online sources for data and information about the Arctic and is Canada's National Antarctica Data Centre.

Sensitivity of freshwater mussel species to various pesticides detected in Ontario, Canada

Freshwater mussels contribute important ecological functions to aquatic systems. The water filtered by mussel assemblages can improve water quality, and the mixing of sediments by burrowing mussels can improve oxygen content and release nutrients. However, nearly 70 percent of North American freshwater mussel species are listed as either endangered, threatened, or in decline. In Ontario, 28 species are in decline or in need of protection. Even though freshwater mussels have a heightened sensitivity to some contaminants, few studies have investigated the risks that various pesticide classes pose to one freshwater mussel species or among life stages. Lampsilis siliquoidea and Villosa iris were the focus of the present study, with the latter currently listed as of "special concern" in Canada. A potential risk to the recovery of freshwater mussel species is the presence and persistence of pesticides in Ontario surface waters. Acute (48 hour) toxicity tests were performed with V. iris glochidia to determine the effect on viability (surrogate for survival) following exposure to 4 fungicides (azoxystrobin, boscalid, metalaxyl, and myclobutanil), 3 neonicotinoids (clothianidin, imidacloprid, and thiamethoxam), 2 carbamates (carbaryl and malathion), 1 organophosphate (chlorpyrifos), and 1 butenolide (flupyradifurone). Juvenile and adult L. siliquoidea were also exposed to azoxystrobin, clothianidin, imidacloprid (juvenile only), and carbaryl (adult only).

Variation in parasite communities in Spottail Shiners (Notropis hudsonius) linked with precipitation

The Richelieu River, Quebec, is a highly-regulated waterway subject to numerous anthropogenic influences from municipal effluents and agricultural activities. Parasite communities in 234 spottail shiners (Notropis hudsonius) were examined from 4 localities in late spring 2003 and 2004. Parasite component community similarity among localities could not be directly linked to available upstream water quality measurements or anthropogenic activity and was best explained by precipitation. This study suggests that fish parasite species composition and richness in the Richelieu River are influenced by environmental parameters which in turn ultimately are driven by a combination of climatic conditions and anthropogenic activities in the watershed.

Supplemental Information

The St. Lawrence Action Plan (SLAP) 2011 to 2026 (see http://planstlaurent.qc.ca/en/home.html) is the latest Canada-Quebec Agreement on the St. Lawrence and builds on the four previous agreements implemented since 1988.

The agreement aims to conserve and enhance the St. Lawrence. It is based on strong collaboration and the pooling of resources and expertise between the governments of Canada and Quebec. As part of their respective responsibilities for the management of the St. Lawrence basin, these two governments recognize the need for close cooperation to tackle the environmental challenges facing this important ecosystem. Other partners are also joining in this initiative, including local organizations, environmental groups, research centres, and universities.

Neonicotinoid concentrations in water and fish health metrics for Pumpkinseed in areas of Essex County

Neonicotinoids are the most widely used insecticides in the world and selective toxicity has resulted in the rapid and ubiquitous use of these compounds. Neonicotinoids are a class of neuro-active insecticides chemically similar to nicotine and are widely used in agriculture to protect crops from various insects. They are also used for other purposes, including killing insects in homes, controlling fleas on pets, and protecting trees from invasive insects such as the Emerald Ash borer. To date Imidacloprid is the most widely used insecticide in the world. The neonicotinoid family focused in this study includes acetamiprid, clothianidin, imidacloprid, dinotefuran, thiacloprid and thiamethoxam. 
The objective of this study was to collect and assess fish health metrics and neonicotinoid concentrations in water from four creeks and streams (Cedar Creek, Hillman Marsh, Sturgeon Creek, and Lebo Creek) within Essex County, Ontario Canada.

Perfluoroalkyl substances (PFAS) in the Canadian Arctic marine ecosystem

This dataset contains concentrations of perfluoroalkyl substances (PFAS) in seawater sampled in various locations in the Arctic ranging from 2005-2008.

Perfluoroalkyl acids (PFAAs) are ubiquitous contaminants of marine, freshwater and terrestrial environments, including remote arctic wildlife. Slow, and long-range oceanic transport from source regions in the northern hemisphere is hypothesized to be among the major pathways contributing to PFAA contamination in remote marine environments. 

The Arctic Ocean is influenced by Pacific and Atlantic seawater as well as riverine outflows. Surface waters of the Beaufort and Chukchi Seas and the western parts of the Canadian archipelago originate from Pacific waters and from major freshwater outflows from Russian, Alaskan, and western Canadian Arctic rivers. Waters of Baffin Bay and the northern Labrador Sea are influenced by Atlantic waters and the east Greenland current. Major inflowing rivers in Europe and North America deliver tons of PFAAs per year into the Atlantic Ocean and adjacent seas.
