Aquatic Toxicity Assessment of Phosphate Compounds

Environmental Health and Toxicology, 2013
Tricalcium phosphate and calcium hydrogenorthophosphate are high production volume chemicals, mainly used as foodstuff additives, pharmaceuticals, lubricants, synthetic resin, and disinfectants. Phosphate has the potential to cause increased algal growth leading to eutrophication in the aquatic environment.

Microplastics as vectors of pharmaceuticals in aquatic organisms – An overview of their environmental implications

Case Studies in Chemical and Environmental Engineering, 2021
Microplastics (MPs) have been recognized as an environmental threat due to their persistence, ubiquity, and toxicity potential. Due to their small size, MPs are endowed with a large specific surface area, having the ability to sorb and accumulate other ...

Rapid toxicity assessment of six antifouling booster biocides using a microplate-based chlorophyll fluorescence in Undaria pinnatifida gametophytes [PDF]

, 2020
Biocides of antifouling agents can cause problems in marine ecosystems by damaging to non-target algal species. Aquatic bioassays are important means of assessing the quality of water containing mixtures of contaminants and of providing a safety standard

Continuous‐Flow Photocatalytic Degradation of Glyphosate and Aminomethylphosphonic Acid Under Simulated Sunlight with TiO2‐Coated Poly(vinylidene fluoride) Membrane

Advanced Functional Materials, EarlyView.
Glyphosate (GLY) and its primary metabolite, aminomethylphosphonic acid (AMPA), are photodegraded using a poly(vinylidene fluoride) membrane with immobilized titanium dioxide (PVDF‐TiO2) in a continuous flow‐through operation under solar light. At optimized conditions, the PVDF‐TiO2 membrane achieved 95% GLY and 80% AMPA removal with •O2− as the ...

Can we predict community-wide effects of herbicides from toxicity tests on macrophyte species? [PDF]

, 2011
Macrophyte communities play an essential role in the way freshwater ecosystems function. It is thus of great concern to understand how environmental factors, especially anthropogenic ones, influence their composition and diversity.

Estimating non-specific aquatic toxicity for the fathead minnow using surrogate chromatographic models

Journal of Chromatography Open
In the assessment of aquatic toxicity, the fathead minnow (Pimephales promelas), a small fish species, is commonly used as an indicator. A major challenge in environmental risk assessment is predicting the aquatic toxicity of tens of thousands of ...

Tailoring the Properties of Functional Materials With N‐Oxides

Advanced Functional Materials, EarlyView.
The properties of materials bearing N‐oxide groups are often dominated by the polar N+─O− bond. It provides hydrophilicity, selective ion‐binding, electric conductivity, or antifouling properties. Many of the underlying mechanisms have only recently been discovered, and the interest in N‐oxide materials is rapidly growing.
