Steroid hormones (SHs) have received widespread attention in recent years. However, current studies of SHs have primarily focused on estrogenic substances, with androgen-related studies being quite limited. We optimized the solid-phase extraction (SPE) pretreatment method, as well as the enzymolysis conditions of five androgens (androstenedione, boldenone, methandienone, nandrolone, and testosterone)

Environmental Risk Assessment with Energy Budget Models: A Comparison Between Two Models of Different Complexity Environ. Toxicol. Chem. (IF 4.1) Pub Date : 2023-12-05 Carlo Romoli, Tjalling Jager, Marie Trijau, Benoit Goussen, Andrè Gergs
The extrapolation of effects from controlled standard laboratory tests to real environmental conditions is a major challenge facing ecological risk assessment (ERA) of chemicals. Toxicokinetic–toxicodynamic (TKTD) models, such as those based on dynamic energy budget (DEB) theory, can play an important role in filling this gap. Through the years, different practical TKTD models have been derived from

Updated Chronic Copper Bioavailability Models for Invertebrates and Algae Environ. Toxicol. Chem. (IF 4.1) Pub Date : 2023-11-29 Charlotte Nys, Patrick Van Sprang, Stephen Lofts, Stijn Baken, Katrien Delbeke, Karel De Schamphelaere
Chronic copper (Cu) bioavailability models have been successfully implemented in European risk assessment frameworks and compliance evaluations. However, they were developed almost two decades ago, which calls for an update. In the study, we present updated chronic Cu bioavailability models for invertebrates and algae. They consider recent ecotoxicity data sets and use the more recent speciation model

No Effect of Realistic Concentrations of Polyester Microplastic Fibers on Freshwater Zooplankton Communities Environ. Toxicol. Chem. (IF 4.1) Pub Date : 2023-11-29 Natasha Klasios, Jihyun O. Kim, Michelle Tseng
Zooplankton are a conduit of energy from autotrophic phytoplankton to higher trophic levels, and they can be a primary point of entry of microplastics into the aquatic food chain. Investigating how zooplankton communities are affected by microplastic pollution is thus a key step toward understanding ecosystem-level effects of these global and ubiquitous contaminants. Although the number of studies

A prior multigenerational perfluorooctane sulfonic acid (PFOS) exposure investigation in zebrafish reported adverse effects at 0.734 µg/L, among the lowest aquatic effect levels for PFOS reported to date. The present three-generation PFOS exposure quantified survival, growth, reproduction, and vitellogenin (VTG; egg yolk protein) responses in zebrafish, incorporating experimental design and procedural

Ecotoxicity and Risk to Zooplankton of a Novel Insecticide Used in Rice Paddies in a Simulated Ecosystem Environ. Toxicol. Chem. (IF 4.1) Pub Date : 2023-11-22 Lang Chen, Shankui Yuan, Leiming Cai, Baohua Tang, Yanming Zhou, Xin Xin Zhou, Chengtian Huang, Yu Zhao, Hairong Yang, Shuai Lan
Diamide insecticides are widely used in rice paddies and pose a potential threat to aquatic organisms. However, the risk research related to their application in major rice-producing areas is very limited, especially mesocosm research to simulate the impact on aquatic ecosystems of long-term exposure, as well as exposure analysis based on local models and local scenarios. To assess potential risks

Honey Bees and Associated Matrices as Biomonitors of Soil Trace Elements: Assessment of their Sensitivity in a Regional Rural Environment Environ. Toxicol. Chem. (IF 4.1) Pub Date : 2023-11-21 Lukáš Praus, Sára Urbanová, Jiřina Száková
Honey bees (Apis mellifera L.) represent a random biosampler integrating pollutants over space and time. An effective biomonitor for trace element (TE) pollution should provide a linear response to TE levels in the environment. However, uncertainties in detecting TEs originating in soil limit their use. To address this, nine experimental sites with multiple apiaries were established in the Upper Palatine
