Bridging the Gap Between Human Toxicology and Ecotoxicology Under One Health Perspective by a Cross‐Species Adverse Outcome Pathway Network for Reproductive Toxicity

Environmental Toxicology and Chemistry, EarlyView.
Cross‐species extrapolation of adverse outcome pathway network on reproductive toxicity under the One Health perspective using new approach methodologies. AOP = adverse outcome pathway. Abstract Although ecotoxicological and toxicological risk assessments are performed separately from each other, recent efforts have been made in both disciplines to ...

2018 State-of the Science of Dispersants and Dispersed Oil (DDO) in U.S. Arctic Waters: Eco-Toxicity and Sublethal Impacts [PDF]

, 2018
Chemical dispersants were employed on an unprecedented scale during the Deepwater Horizon oil spill in the Gulf of Mexico, and could be a response option should a large spill occur in Arctic waters. The use of dispersants in response to that spill raised

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 use of simulated whole effluents in toxicity assessments: A review of case studies from reverse osmosis desalination plants [PDF]

, 2014
Seawater desalination is an increasingly common means to meet the demand for freshwater. Resulting wastewater discharges can, however, impact biota of the surrounding environment.

Hierarchical modelling of species sensitivity distribution: development and application to the case of diatoms exposed to several herbicides

, 2015
The Species Sensitivity Distribution (SSD) is a key tool to assess the ecotoxicological threat of contaminant to biodiversity. It predicts safe concentrations for a contaminant in a community.

Inconsistent Transcriptomic Responses to Hexabromocyclododecane in Japanese Quail: A Comparative Analysis of Results From Four Different Study Designs

Environmental Toxicology and Chemistry, EarlyView.
Abstract Efforts to use transcriptomics for toxicity testing have classically relied on the assumption that chemicals consistently produce characteristic transcriptomic signatures that are reflective of their mechanism of action. However, the degree to which transcriptomic responses are conserved across different test methodologies has seldom been ...

Study on impacts of direct supplementation of choline into semi-intensive fish culture system based on haematopoietic alterations

Environmental and Sustainability Indicators, 2021
The present study investigated the impact of choline chloride at the dose of 350 ​g bigha−1 fortnightly for 90 days culture on Indian Major Carps (IMCs) (Labeo rohita, Catla catla) and Air-breathing fishes (Clarias batracus and Anabas testudineus) in ...

Implications of differences between temperate and tropical freshwater ecosystems for the ecological risk assessment of pesticides [PDF]

Despite considerable increased pesticide use over the past decades, little research has been done into their fate and effects in surface waters in tropical regions.
