The Swiss Ecotox Centre: bridging the gap between research and application

Environmental Sciences Europe, 2018
The Swiss Centre for Applied Ecotoxicology (Ecotox Centre) was created in recognition of the urgent societal need to provide expertise, education and tools for assessing the risks and effects of anthropogenic chemicals in the environment. Founded in 2008,

Timing matters: impact of different frequencies of low pesticide pulses on aquatic invertebrates

Environmental Sciences Europe
Background Aquatic communities are constantly exposed to multiple pulses of pesticides caused by spray drift or runoff that can have significant short- and long-term effects.

The relationship between cellular protein content and selenium accumulation in freshwater microalgae

Integrated Environmental Assessment and Management, EarlyView.
Abstract Variability in the bioconcentration of selenium (Se) by primary producers at the base of the food web results in uncertainty in predictions of bioaccumulation and ecological risk to higher trophic level organisms. Water chemistry, speciation of Se, and periphyton community composition have all been suggested as factors that contribute to ...

Moderate Biochar–Compost Mixture Is More Effective in Improving Biomass, Nutrient Fluxes, and Photosynthetic Outputs for Sustainable Land Restoration and Soil Fertility

Land Degradation &Development, EarlyView.
ABSTRACT Soil nutrient depletion severely constrains crop productivity in degraded and saline environments. Strategies such as biochar–compost integration could be useful for sustainable agriculture and land restoration on a global scale. This study evaluated the effects of biochar (1% Bc), compost (1% Co), and their blends (0.5% Bc + 0.5% Co and 1% Bc

Essential oils as bioherbicides: effects of orange and citronella oils on weed germination and early growth

Pest Management Science, EarlyView.
Essential oils from orange and citronella showed dose‐dependent inhibition of weed germination and early growth, highlighting their potential as bioherbicides and sustainable tools for integrated weed management. Abstract BACKGROUND Increasing selection of herbicide‐resistant weed biotypes has intensified the search for alternatives to the intensive ...

Nanomaterials' Multigenerational Effects by Single and Joint Exposure in Non‐mammalian Models

Environmental Toxicology, EarlyView.
ABSTRACT Nanotoxicology has mainly focused on single‐generation studies, leaving multigenerational toxicity underexplored. Having animal welfare recently gained importance, we aimed to provide the state‐of‐the‐art of knowledge about multigenerational effects in non‐mammalian models in the case of nanomaterials (NM) single and joint exposure to other ...

Comprehensive Evaluation of Bisphenol A Toxicity Reveals Neurobehavioral, Metabolic, and Reproductive Impairments in Girardia tigrina

Environmental Toxicology, EarlyView.
ABSTRACT Bisphenol A (BPA), a common industrial chemical used in plastics and consumer products, is increasingly detected in aquatic environments, raising serious concerns about its potential ecological impacts. This study evaluated the sublethal and acute toxic effects of BPA on the freshwater planarian Girardia tigrina, a recognized model for ...

Exploring Interactive Effects of Arsenic and Selenium Exposure on Larval Zebrafish (Danio rerio)

Environmental Toxicology, EarlyView.
ABSTRACT Arsenic contamination in aquatic ecosystems is a major environmental concern. Selenium (Se) helps mitigate oxidative stress and hence could reduce the toxic effects of arsenic. However, Se can also be toxic at high concentrations. Given that these metalloids commonly co‐occur in the environment, there is a pressing need for further research ...

Polycyclic Aromatic Hydrocarbons in Ologe Lagoon and Effects of Benzo[b]fluoranthene in African Catfish

Journal of Health and Pollution, 2019
Background. Ologe Lagoon is an important water body that receives effluents from neighboring industries. These effluents may increase the levels of anthropogenic contaminants in the lagoon, thereby creating stressors for aquatic organisms. Objectives. To
