Biodiversity Buffers Phytoplankton Biomass Production Against Nanoparticle Pollution Through Increased Facilitation. [PDF]

Ecol Lett
Biodiversity can buffer ecosystems against environmental stressors, yet its role under nanoparticle pollution remains unclear. Using freshwater phytoplankton communities exposed to copper oxide nanoparticles, we show that higher species richness alleviates productivity losses through increased facilitation among species.

Safety of the preparation of monensin sodium (Coxidin®) produced with <i>Streptomyces</i> sp. LMG S-19095 as a coccidiostat for chickens for fattening and chickens reared for laying (Huvepharma N.V.). [PDF]

EFSA J
Abstract Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety of monensin sodium (Coxidin®) produced with Streptomyces sp. LMG S‐19095 as a coccidiostat for chickens for fattening, chickens reared for laying, turkeys for fattening and turkeys reared for breeding.

Stereoselective bioactivity, toxicity and degradation of novel fungicide sedaxane with four enantiomers under rice-wheat rotation mode

Ecotoxicology and Environmental Safety, 2022
Sedaxane was a novel chiral fungicide that contains four enantiomers. Unfortunately, the stereoselective bioactivity, toxicity and degradation of sedaxane have not been clarified.

Removal of estrogens from primary settled sewage by repeated culture of Selenastrum capricornutum

Water Science and Technology, 2023
Biotransformation and biodegradation of estrogenic compounds by bacteria and even fungi have been reported widely, but the role of microalgae in the elimination of estrogens from municipal wastewater treatment plants and their interaction with other ...

Surfactant (Genapol OX-80) toxicity to Selenastrum capricornutum [PDF]

Chemosphere, 2000
A non-ionic surfactant (Genapol OX-80) was proposed as a means of reducing destructive crayfish activity in rice. In order to study the toxicity of this product on algae, a test in accordance to the ISO 8692 protocol (1989) was performed. The growth inhibiting effect of the pure formulation of Genapol OX-80 was studied on Selenastrum capricornutum in ...

Applicability of Chronic Multiple Linear Regression Models for Predicting Zinc Toxicity in Australian and New Zealand Freshwaters

Environmental Toxicology and Chemistry, Volume 42, Issue 12, Page 2614-2629, December 2023., 2023
Abstract Bioavailability models, for example, multiple linear regressions (MLRs) of water quality parameters, are increasingly being used to develop bioavailability‐based water quality criteria for metals. However, models developed for the Northern Hemisphere cannot be adopted for Australia and New Zealand without first validating them against local ...

A Framework for Algae Modeling in Regulatory Risk Assessment

Environmental Toxicology and Chemistry, Volume 42, Issue 8, Page 1823-1838, August 2023., 2023
Abstract The use of toxicokinetic–toxicodynamic (TKTD) modeling in regulatory risk assessment of plant protection products is increasingly popular, especially since the 2018 European Food Safety Authority (EFSA) opinion on TKTD modeling announced that several established models are ready for use in risk assessment.

Chronic Toxicity of Iron to Aquatic Organisms under Variable pH, Hardness, and Dissolved Organic Carbon Conditions

Environmental Toxicology and Chemistry, Volume 42, Issue 6, Page 1371-1385, June 2023., 2023
Abstract A series of chronic toxicity tests was conducted exposing three aquatic species to iron (Fe) in laboratory freshwaters. The test organisms included the green algae Raphidocelis subcapitata, the cladoceran Ceriodaphnia dubia, and the fathead minnow Pimephales promelas.

Are standard aquatic test species and methods adequate surrogates for use in environmental risk assessment of pesticides in tropical environments?

Integrated Environmental Assessment and Management, Volume 19, Issue 1, Page 202-212, January 2023., 2023
Abstract In regulatory risk assessment, surrogate species of fish, aquatic invertebrates, and primary producers are tested to assess toxicity and subsequently the risk of pesticides to freshwater biota. This study evaluates whether the standard, surrogate test species (mostly temperate in latitudinal distribution) used in many parts of the world are ...

Safety of a feed additive consisting of semduramicin sodium (Aviax 5%) for chickens for fattening (Phibro Animal Health s.a.)

EFSA Journal, Volume 20, Issue 8, August 2022., 2022
Abstract Following a request from the European Commission, the Panel on Additives and Products or substances used in Animal Feed (FEEDAP Panel) was asked to deliver a scientific opinion on the safety of the coccidiostat Aviax 5% (semduramicin sodium) when used in feed for chickens for fattening.
