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 ...

Mixture toxicity of copper, cadmium and zinc to barley seedlings is not explained by antioxidant and oxidative stress biomarkers
Metal mixture toxicity analysis to plants is complicated by mutual interactions. Here, mixture effects of zinc (Zn), cadmium (Cd) and copper (Cu) on barley (Hordeum vulgare L.) root elongation were analysed using oxidative stress parameters. The ...

Global transcriptomic profiling in barramundi Lates calcarcifer from rivers impacted by differing agricultural land‐uses
Most catchments discharging into the Great Barrier Reef (GBR) lagoon have elevated loads of suspended sediment, nutrients, and pesticides, including photosystem II inhibiting herbicides, associated with upstream agricultural land use. To ...

Life stage sensitivity of the marine mussel Mytilus edulis to ammonia
Ammonia is an important contaminant to consider in all toxicity tests. It is especially important to consider the impacts of ammonia in test methods that use sensitive water column organisms exposed to sediments or sediment extracts, such as pore ...

Development and validation of a chronic Pb bioavailability model for the freshwater rotifer Brachionus calyciflorus
We investigated the univariate effects of Ca, pH and DOC on chronic (48h) Pb toxicity to the freshwater rotifer Brachionus calyciflorus. High pH (8.2) and higher concentrations of DOC were protective against filtered Pb toxicity, whereas Ca was ...

Integrating ecosystem services into crop protection and pest management: Case study with the soil fumigant 1,3‐dichloropropene and its use in tomato production in Italy
Ecosystems provide the conditions for producing food, regulating water, and providing wildlife habitats; these, among others, are known as ecosystem services (ESs). Food production is both economically and culturally important to southern ...

LCA case study on lawn establishment and maintenance with various peat and compost contents in substrates
The environmental impacts of the establishment and maintenance of lawn, including the production and use of various substrates, were analyzed by life cycle assessment (LCA). The project focused on comparing substrates with different peat and ...

Analysis and dissipation of the antiparasitic agent ivermectin in cattle dung under different field conditions
Cattle treated with the veterinary parasiticide ivermectin (IVM) fecally excrete residues. Here we report the exposition and dissipation characteristics of these residues in dung of IVM‐treated cattle, and in soil beneath this dung, on pastures ...

Potential risks to freshwater aquatic organisms following a silvicultural application of herbicides in Oregon's Coast Range
Glyphosate, aminomethylphosphonic acid (AMPA), imazapyr, sulfometuron methyl (SMM), and metsulfuron methyl (MSM) were measured in streamwater collected during and after a routine application of herbicides to a forestry site in Oregon's Coast ...

Anti‐anxiety drugs and fish behaviour: Establishing the link between internal concentrations of oxazepam and behavioural effects
Psychoactive drugs are frequently detected in the aquatic environment. The evolutionary conservation of the molecular targets of these drugs in fish suggest that they may elicit mode‐of‐action mediated effects in fish as they do in humans, and ...

Current use pesticides in seawater and their bioaccumulation in polar bear‐ringed seal food chains of the Canadian Arctic
The distribution of current use pesticides (CUPs) in seawater, and their trophodynamics were investigated in three Canadian Arctic marine food chains. The greatest ranges of dissolved‐phase concentrations in seawater for each CUP were endosulfan ...

Soil organic matter content effects on dermal pesticide bioconcentration in American toads (Bufo americanus)
Pesticides have been implicated as a major factor in global amphibian declines and may pose great risk to terrestrial phase amphibians moving to and from breeding ponds on agricultural landscapes. Dermal uptake from soil is known to occur in ...
-
Glyphosate and AMPA chronic risk assessment for soil biota
Glyphosate is a broad‐spectrum herbicide used widely in agriculture, horticulture, private gardens and in public infrastructure, where it is applied to areas such as road sides, railway tracks and parks to control the growth of weeds. The ...

Local and interannual variations in mercury and cadmium in eggs of eight seabird species of the Sinaloa coast, México
Mercury (Hg) and cadmium (Cd) concentrations in eggs of eight seabird species inhabiting five coastal ecosystems in Sinaloa, México were determined during two breeding seasons (2012 and 2013): Blue‐footed Booby (BFBO; Sula nebouxii), Brown Booby ...

Interactive effects of temperature and glyphosate on the behavior of blue ridge two‐lined salamanders, Eurycea wilderae
The objective of the present study was to evaluate the potential interactive effects of stream temperatures and environmentally relevant glyphosate‐based herbicide concentrations on movement and anti‐predator behaviors of larval Eurycea wilderae ...

Mummichog (Fundulus heteroclitus) continue to successfully produce eggs after exposure to high levels of 17Α‐ethinylestradiol
17α‐Ethinylestradiol (EE2) is a potent estrogen used in birth‐control pills. Previous laboratory and field studies have shown negative impacts in a variety of fish species after exposure to low levels of EE2, most notably a nearly complete ...

Stage‐dependent and sex‐dependent sensitivity to water‐soluble fractions of fresh and weathered oil in the marine copepod Calanus finmarchicus
Acute toxicity differs between species but also varies within a species. Important intraspecific factors are the exposure duration and properties of the animal such as life stage, sex, and physiological status. In the present study, the acute ...

Barley root hair growth and morphology in soil, sand, and water solution media and relationship with nickel toxicity
Barley, Hordeum vulgare (Doyce), was grown in the three media of soil, hydroponic sand solution (sand), and hydroponic water solution (water) culture at the same environmental conditions for 4 d (days). Barley roots were scanned and root ...

A four‐country ring test of nontarget effects of ivermectin residues on the function of coprophilous communities of arthropods in breaking down livestock dung
By degrading the dung of livestock that graze on pastures, coprophilous arthropods accelerate the cycling of nutrients to maintain pasture quality. Many veterinary medicinal products, such as ivermectin, are excreted unchanged in the dung of ...
