Exploring reach as potential data source for characterizing ecotoxicity in life cycle assessment
Toxicity models in life cycle impact assessment (LCIA) currently only characterize a small fraction of marketed substances. This is mainly due to limitations in the underlying ecotoxicity data. One approach to improve the current data situation ...

Splenic immunotoxicity in developing cane toads (Rhinella marina) from Bermuda
The impacts of contaminated sediment from 2 ponds in Bermuda on immune function in newly metamorphosed cane toads were examined. In the present study, a partial life‐cycle experiment exposing Gosner stage 20 cane toad tadpoles to pond sediment ...

The influence of salinity on the fate and behavior of silver standardized nanomaterial and toxicity effects in the estuarine bivalve Scrobicularia plana
Because of their antibacterial properties, silver (Ag) engineered nanomaterials are included in many products. The present study used a standardized Ag nanomaterial (NM‐300K, 20 nm) supplied with a stabilizing agent. The aim was to investigate ...

Comparing the sensitivity of chlorophytes, cyanobacteria, and diatoms to major‐use antibiotics
The occurrence of antibiotic residues in the aquatic environment is an emerging concern. In contrast to daphnia and fish, algae are known to be particularly sensitive to antibiotic exposure. However, to date, a systematic evaluation of the ...

Physiological and cellular responses of oysters (Crassostrea hongkongensis) in a multimetal‐contaminated estuary
The Pearl River estuary, southern China, suffers from multiple sources of metal contamination as a result of the rapid industrial development in the region; but the biological impacts of contamination remain unknown. In the present study, a ...

Multiphase partitioning and risk assessment of endocrine‐disrupting chemicals in the Pearl River, China
Multiphase partitioning of endocrine‐disrupting chemicals (EDCs) in the Pearl River (China) were investigated. The colloidal concentrations for 4‐tert‐octylphenol, 4‐nonylphenol, bisphenol A (BPA), and estrone (E1) were in the ranges of 0.2 ng/L ...

Multigenerational effects of carbendazim in Daphnia magna
Carbendazim is a fungicide largely used in agriculture as a plant protection product. Due to agricultural runoffs, drainage and leaching it reaches surface waters at concentrations possibly hazardous to aquatic communities. Due to potential and ...

Assessing toxicity of contaminants in riverine suspended sediments to freshwater mussels
The Clinch River in Virginia and Tennessee, USA, is well known for its diverse native freshwater mussel assemblages; however, notable declines in mussel populations in recent decades have prompted much concern and subsequent research. The authors ...

Don't be fooled—A no‐observed‐effect concentration is no substitute for a poor concentration–response experiment
Renowned mathematician and science historian Jacob Bronowski once defined science as “the acceptance of what works and the rejection of what does not” and noted “that needs more courage than we might think.” Such would also seem to be the case ...

Effects of two fungicide formulations on microbial and macroinvertebrate leaf decomposition under laboratory conditions
Aquatic fungi contribute significantly to the decomposition of leaves in streams, a key ecosystem service. Little is known, however, about the effects of fungicides on aquatic fungi and macroinvertebrates involved with leaf decomposition. Red ...

Impacts of Deepwater Horizon crude oil exposure on adult mahi‐mahi (Coryphaena hippurus) swim performance
The temporal and geographic attributes of the Deepwater Horizon incident in 2010 likely exposed pelagic game fish species, such as mahi‐mahi, to crude oil. Although much of the research assessing the effects of the spill has focused on early life ...

Alleviation of environmental risks associated with severely contaminated mine tailings using amendments: Modeling of trace element speciation, solubility, and plant assssccumulation
Tailings are considered one of the most relevant sources of contamination associated with mining activities. Phytostabilization of mine spoils may need the application of the adequate combination of amendments to facilitate plant establishment ...

Mechanisms underlying the enhancement of toxicity caused by the coincubation of zinc oxide and copper nanoparticles in a fish hepatoma cell line
Ecosystems are exposed to a wide variety of individual substances, including at the nano‐scale; and the potential adverse effects of their interactions are an increasing concern. The purpose of the present study was to determine whether zinc ...

Physiological differences in the crab Ucides cordatus from two populations inhabiting mangroves with different levels of cadmium contamination
Crustaceans found in metal contaminated regions are able to survive and the authors decided to investigate the physiological mechanisms involved by comparing populations from contaminated and non‐contaminated areas. The objective of the present ...

FTIR spectroscopy as a novel approach towards providing effect‐based endpoints in duckweed toxicity testing
Traditional duckweed toxicity tests only measure plant growth inhibition as an endpoint, with limited effects‐based data. This study aimed to investigate whether Fourier‐transform infrared (FTIR) spectroscopy could enhance the duckweed (Lemna ...

Comparative chronic toxicity of imidacloprid, clothianidin, and thiamethoxam to Chironomus dilutus and estimation of toxic equivalency factors
Non‐target aquatic insects are susceptible to chronic neonicotinoid insecticide exposure during the early stages of development from repeated run‐off events and prolonged persistence of these chemicals. Investigations on the chronic toxicity of ...
