Between April to November of 2017, microplastics (MPs) were analysed in biosolids from two separate suppliers, and the soils three agricultural fields which they applied, Ontario, Canada. Soils a control site with no history biosolid application also examined. High MP concentrations between 8.7 × 103 kg−1 1.4 104 found samples. Lower observed Provider 2 may be due storage, settling supernatant removal prior applications. Annual additions across Ontario estimated at 4.1 1011 1.3 1012...
Climate change is expected to modify rainfall, temperature and catchment hydrological responses across the world, adapting these water-related changes a pressing challenge. This paper reviews impact of anthropogenic climate on water in UK looks at projections future change. The natural variability makes hard detect; only historical increases air can be attributed forcing, but over last 50 years more winter rainfall has been falling intense events. Future evapotranspiration could lead changed...
The catchment of the River Thames, principal river system in southern England, provides main water supply for London but is highly vulnerable to changes climate, land use and population. eutrophic with significant algal blooms phosphorus assumed be primary chemical indicator ecosystem health. In Thames Basin, available from point sources such as wastewater treatment plants diffuse agriculture. order predict vulnerability future change, integrated catchments model (INCA-P) has been applied...
Anthropogenic climate change has impacted and will continue to impact the natural environment people around world.
Sludge and biosolids from wastewater treatment plants (WWTPs), identified as important pathways through which microplastics (MPs) can enter the wider environment, contain high organic content, obstruct MP quantification/identification. Time- cost-effective removal of organics is a significant barrier to analysis. This study aims alleviate these obstacles using widely available store-bought septic tank cleaner, comprised enzymes bacteria. The cleaner was added sludge samples, obtained local...
Subsurface flow pathways of groundwater-fed streams were characterized on a floodplain terrace the Toklat River, Alaska, in summer 2008, to establish influence local physicochemical variability upon macroinvertebrate communities. Streams proximal valley side (A sites) and main meltwater channel (B studied. Chloride natural isotopic tracers (δ18O δ2H) used identify water sources pathways. Results indicated that B sites was dominated by seepage glacial through alluvial aquifer. Streamflow at...
Eutrophication and anoxia are unresolved issues in many large waterbodies. Globally, management success has been inconsistent, highlighting the need to identify approaches which reliably improve water quality. We used a process-based model chain quantify effectiveness of terrestrial nutrient control measures on in-lake nitrogen, phosphorus, chlorophyll dissolved oxygen (DO) concentrations Lake Simcoe, Canada. Across baseline period 2010-2016 hydrochemical outputs from catchment models INCA-N...
Abstract. Hydrological processes determine the transport of nutrients and passage diffuse pollution. Consequently, catchments are likely to exhibit individual hydrochemical responses (sensitivities) climate change, which expected alter timing amount runoff, impact in-stream water quality. In developing robust catchment management strategies quantifying plausible future conditions it is therefore equally important consider potential for spatial variability in, causal factors of, sensitivity,...
While tensions exist between parsimony and completeness, it appears that structural uncertainty is more important than parameter equifinality in controlling rainfall-runoff model performance.
For over a century, governments on both sides of the Canada–US border have employed diverse policy instruments and management tools to protect Great Lakes. This crucial freshwater resource continues show signs degradation. We explore how International Organization for Standardization Risk Management Standard (ISO 31000) can be used by reduce risk failing achieve objectives ISO 31000 facilitates analysis human activities that drive causal pathways ecosystem pressures–effects–impacts analyzes...
AbstractWe report results from a spatially intensive monitoring and modelling study to assess phosphorus (P) dynamics in the Beaver River, tributary of Lake Simcoe, Ontario. We established multiple stations (9 flow 24 water quality stations) headwaters near outflow that were operated for 2 field seasons, complementing longer term data site chemistry site. applied Branched-INCA-P model, which allows fully distributed simulations supported by highly data. Using helped better understand...
The long-term application of road salts has led to a rise in surface water chloride (Cl-) concentrations. While models have been used assess the potential future impacts continued deicing practices, prior approaches not incorporated changes climate that are projected impact hydrogeology 21st century. We use an INtegrated CAtchment (INCA) model simulate Cl- concentrations Tioughnioga River watershed. was run over baseline period (1961-1990) and simulations from range GCMs three 30-year...
The plausibility of land disturbance as a cause declining phosphorus (P) concentrations in oligotrophic lakes within south-central Ontario, Canada, is evaluated using the process-based model INCA-P. was calibrated upon three catchments Muskoka–Haliburton region (MHR): Harp (HP), Dickie (DE), and Plastic (PC), which have varying degrees P export different forms historic disturbances (timber harvesting, tree death, soil acidification, respectively). Hindcasts (1978–2007) were run with without...
Process-based models are commonly used to design management strategies reduce excessive algal growth and subsequent hypoxia. However, targets typically focus on phosphorus control, under the assumption that successful nutrient reduction will solve hypoxia issues. Algal responses drivers not linear depend additional biotic abiotic controls. In order generate a comprehensive assessment of effectiveness control strategies, independent nutrient, dissolved oxygen (DO), temperature must be...
