Modelling chlorophyll-
a in Bohai Bay based on hybrid soft computing approachAlgae bloom has become a serious problem of global concern. Scientists have managed to study it using various mathematical models with different degrees of complexity. However, these conventional modelling approaches are limited due to the complexity of the processes involved, the scarcity of data and spatial heterogeneity. In this study, hybrid soft computing (SC) algorithms, including support ...

Risk mitigation measures for diffuse pesticide entry into aquatic ecosystems: Proposal of a guide to identify appropriate measures on a catchment scale
Measures to mitigate the risk of pesticide entry into aquatic ecosystems are becoming increasingly more important in the management of hot spots of pesticide transfer; such management, for example, is required by the European Union's directive for the sustainable use of pesticides (2009/128/EC). Measures beyond those currently stipulated for pesticide product authorization may be needed. A ...

Integrative assessment of selenium speciation, biogeochemistry and distribution in a northern coldwater ecosystem
For the past decade, considerable research has been conducted at a series of small lakes receiving treated liquid effluent containing elevated selenium (Se) from the Key Lake uranium milling operation in northern Saskatchewan, Canada. Several studies related to this site, including field collections of water, sediment, and biota (biofilm/periphyton, invertebrates, fish, and birds), ...

Forests Serve as Freshwater Infrastructure
Mountain meadows and forests play an important role in capturing and slowly releasing precipitation. Restoring watershed headwaters is examined as a water storage strategy A global realization is dawning about the pressing need for more freshwater storage infrastructure to support growing populations in our time of climate change. Faced with the astronomical costs of constructing such ...

Chilling Discovery: Cold Weather Algae Blooms Uncovered
If you’ve read any of our blogs, you already know the plethora of negative impacts of harmful algal blooms (HABs). From depleted oxygen levels to fish kills, and from skin irritations to liver damage, the consequences of these blooms are well-documented. But when we think of harmful algal blooms (HABs), we typically imagine warm weather and stagnant water, with greenish-blue scum covering ...

Forests Serve as Freshwater Infrastructure
Restoring watershed headwaters is examined as a water storage strategy A global realization is dawning about the pressing need for more freshwater storage infrastructure to support growing populations in our time of climate change. Faced with the astronomical costs of constructing such infrastructure, however, water management is beginning to look at existing natural features that can serve the ...

The structure and origin of dissolved organic matter studied by UV-vis spectroscopy and fluorescence spectroscopy in lake in arid and semi-arid region
To develop a proper indicator which could predict water quality and trace pollution sources is critically important for the management of sustainable aquatic ecosystem. In our study, seven water samples collected from Wuliangsuhai Lake in Inner Mongolia were used. UV-visible spectra and synchronous fluorescence spectra were applied to investigate the humification degree and aromatic structure of ...

SA Environment Protection (Water Quality) Policy 2003
The Environment Protection (Water Quality) Policy 2003 (Water Quality Policy) is a policy that safeguards South Australian water resources from pollution. For a long period, the discrepancies surrounding the South Australian laws protecting the State’s water resources from pollution, have lowered the environmental value of all water resources in South Australia. This implies that all the ...

Financing Carbon Emission Reduction From SMEs To Governments
Everybody is aware that governments and corporations all around the world have made commitments to become net zero. The term net zero has three limbs: Calculate the carbon footprint. Reduce GHG emissions to a minimum. Offset the residual emissions. That seems fairly straight forward on the surface of it but misunderstanding abounds about the Scope 3 emissions that should be included in ...

Understanding Turbidity of Wastewater
What is Turbidity? Turbidity, in the context of wastewater, refers to the cloudiness or haziness of the water caused by the presence of suspended particles such as clay, silt, and organic matter. These particles scatter and absorb light, making the water appear cloudy. Turbidity is often an indicator of the overall water quality and can impact aquatic ecosystems and human health. Importance of ...
