A comprehensive review on the sources, environmental behavior, and degradation of alkylphenol ethoxylates and their metabolites in surface water and soils

Journal of Environmental Quality, Volume 54, Issue 6, Page 1631-1652, November/December 2025.
Abstract Alkylphenol ethoxylates (APEOs) and their metabolites, widely used in agricultural, industrial, and household products, are known endocrine disruptors. Since the 1980s, many countries have implemented restrictions on their production and use, necessitating an evaluation of these regulations by reviewing their source and environmental behavior ...

A Novel Miniature Culture System to Screen CO2-Sequestering Microalgae

Energies, 2012
In this study, a novel 96-well microplate swivel system (M96SS) was built for high-throughput screening of microalgal strains for CO2 fixation. Cell growth under different CO2 supply conditions (0.2, 0.4, 0.8, and 1.2 g L−1 d−1), residual nitrate, and pH

Seasonal Variation of Enzymatically Hydrolyzable Organic Phosphorus in Agricultural Drainage Waters

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 7, July 2025.
Abstract Phosphorus (P) export studies in agricultural watersheds have generally focused on soluble reactive P (SRP), the P fraction generally considered as readily available for biological uptake. However, in some settings, the amount of dissolved organic P (DOP) in agricultural drainage waters can be significant and may represent another important ...

Exposure, body size, and zooplankton overland dispersal capacity

Limnology and Oceanography, Volume 70, Issue 1, Page 15-24, January 2025.
Abstract The dormant life stages of freshwater zooplankton are generally resistant to environmental exposure, and this facilitates their overland dispersal. However, environmental exposure and overland dispersal are less well studied for the active life stages of freshwater zooplankton.

Impact of Microalgal‐Based Diets on Growth, Proximate, Fatty Acid, and Amino Acid Profiles in Daphnia magna

Aquaculture Research, Volume 2025, Issue 1, 2025.
Water flea (Daphnia magna) is an important live prey species for feeding larvae and juvenile fish and is also used as a feed ingredient in aquaculture. The growth performance and nutritional content of D. magna can be enhanced by diets. In this study, one freshwater microalgae Euglena gracilis (EG), one marine microalgae Pavlova lutheri (PL), and four ...
