Water Quality and River Plume Monitoring in the Great Barrier Reef: An Overview of Methods Based on Ocean Colour Satellite Data

Remote Sensing, 2015
A strong driver of water quality change in the Great Barrier Reef (GBR) is the pulsed or intermittent nature of terrestrial inputs into the GBR lagoon, including delivery of increased loads of sediments, nutrients, and toxicants via flood river plumes ...

Effects of fungicides on aquatic fungi and bacteria: a comparison of morphological and molecular approaches from a microcosm experiment

Environmental Sciences Europe, 2023
Background Fungicides are frequently used in agriculture and can enter freshwater ecosystems through multiple pathways. The negative impacts of fungicides on microorganisms, fungi in particular, and their functions such as leaf decomposition have been ...

Polylactic Acid (PLA), Polycaprolactone (PCL), and Chitosan: the Biodegradable Transition in Medical Waste Management

Advanced Sustainable Systems, EarlyView.
The shift to biodegradable materials in healthcare promises reduced plastic pollution, but their production, adoption, and long‐term impacts remain complex. Integrating lifecycle insights with global policy coordination is essential for meaningful environmental gains. Abstract The COVID‐19 pandemic sharply increased medical waste, intensifying concerns

Change in metallothionein phosphorylation state in Mya arenaria clams: implication in metal metabolism and oxidative stress

Invertebrate Survival Journal, 2010
The contamination of the benthic environment poses a threat to long-lived sessile organisms such as clams. The purpose of this study was to investigate metal contamination in tissues and changes in metallothioneins (MT) in respect to its redox status in ...

Direct and Indirect Climate Change Impacts on Brown Trout in Central Europe: How Thermal Regimes Reinforce Physiological Stress and Support the Emergence of Diseases

Frontiers in Environmental Science, 2020
Water temperature is one of the most important abiotic parameters in rivers having direct and indirect effects on fish. Especially cold-water species like the brown trout (Salmo trutta) are limited by high temperatures. Beside direct physiological stress,

Corn Zein Nanocarriers for Agrochemical Delivery and Smart Packaging

Advanced Sustainable Systems, EarlyView.
This review explores zein, a corn‐derived biodegradable protein, as a multifunctional nanocarrier for sustainable agriculture and packaging. It examines advances in agrochemical delivery, smart packaging, and stimuli‐responsive systems, while addressing scalability, environmental fate, and regulatory barriers.

Effect of Hydrological Connectivity on the Phosphorus Buffering Capacity of an Urban Floodplain

Frontiers in Environmental Science, 2020
Floodplains can perform nutrient buffering functions and therefore influence the riverine nutrient dynamics depending on the extent of the hydrological connectivity.

The importance of periodic droughts for maintaining diversity in the freshwater environment [PDF]

, 1996
Whereas some species may rely on periodic drought conditions for part of their life histories, or have life strategies suited to exploiting the habitat or changed environmental conditions that are created by drought, for other organisms it is a time of ...
