Rhizospheric pore-water content predicts the biochar-attenuated accumulation, translocation, and toxicity of cadmium to lettuce

open access: yesEcotoxicology and Environmental Safety, 2021
Metal bioavailability controls its behaviors in soil-plant system, especially involved in biochar amendment. This study compared a rhizospheric pore-water extraction against a BCR sequential extraction method to understand cadmium (Cd) bioavailability in

Polystyrene nanoplastics mediated the toxicity of silver nanoparticles in zebrafish embryos

open access: yesFrontiers in Marine Science, 2023
The widespread distribution of nanoplastics and nanomaterials in aquatic environments is of great concern. Nanoplastics have been found to modulate the toxicity of other environmental pollutants in organisms, while few studies have focused on their ...

Alternative Attractors of Shallow Lakes [PDF]

open access: yesThe Scientific World JOURNAL, 2001
Ponds and shallow lakes can be very clear with abundant submerged plants, or very turbid due to a high concentration of phytoplankton and suspended sediment particles. These strongly contrasting ecosystem states have been found to represent alternative attractors with distinct stabilizing feedback mechanisms.

Degradation of river ecological quality in Tibet plateau with overgrazing: A quantitative assessment using biotic integrity index improved by random forest

open access: yesEcological Indicators, 2021
The river ecosystem in fragile regions is especially vulnerable to environmental or anthropogenic stressors. The ecological quality and stability of rivers in fragile regions urgently need to be evaluated before the reasonable protection and restoration.

Climate-dependent CO2 emissions from lakes [PDF]

open access: yes, 2010
Inland waters, just as the world's oceans, play an important role in the global carbon cycle. While lakes and reservoirs typically emit CO2, they also bury carbon in their sediment.

Adsorption Behaviors of 17α-Ethinylestradiol in Sediment-Water System in Northern Taihu Lake, China

open access: yesThe Scientific World Journal, 2014
Adsorption behavior of 17α-ethinylestradiol (EE2) in northern Taihu Lake sediment was analyzed by using batch equilibrium experiment. Freundlich isotherm could describe the adsorption thermodynamic behavior of EE2 in sediment.

Microbial carbon metabolic functions of biofilms on plastic debris influenced by the substrate types and environmental factors

open access: yesEnvironment International, 2020
As an artificial type of microbial carrier, plastic debris has been widely detected in freshwater habitats, and the potential impacts of the plastisphere (biofilms colonized on plastics) in aquatic ecosystems have drawn increasing attention.

Comparative algological and bacteriological examinations on biofilms developed on different substrata in a shallow soda lake [PDF]

open access: yes, 2008
According to the European Water Framework Directives, benthic diatoms of lakes are a tool for ecological status assessment. In this study, we followed an integrative sample analysis approach, in order to find an appropriate substratum for the water ...
