Dataset consists of 4-day, 14-day, and full life responses of laboratory cultured mayflies (Neocloeon triangulifer) to perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA). Responses were measured as survival at 4 days, 14 days, pre-emergent nymph (PEN) stage, and emergence; 14-day length; number of days to PEN stage, and imago live weight. Water quality and analytical chemistry results associated with toxicity data are included.

Dataset consists of 4, 7, 10, and 14-day responses of laboratory cultured mayflies (Neocloeon triangulifer) to sodium chloride exposure under different test condition scenarios. Responses were measured as mortality and growth (length). Water quality and analytical chemistry results associated with toxicity data are included. Experiments included 1) testing the influence of organism age on mortality and growth in 7-day tests, 2) testing the influence of test duration on mortality and growth, 3) testing the influence of temperature on mortality and growth, 4) testing the influence of nutrient amendments to mayfly test dilution water on mortality and growth

This data set includes mortality data from acute toxicity tests with aquatic larvae of the mayfly, Neocloeon triangulifer, exposed to sodium chloride. Two separate tests were conducted and fed diatom diets that were either 7-days-old or 13-days-old.

Recent concern for the adverse effects from neonicotinoid insecticides has centered on risk for insect pollinators in general and bees specifically. However, natural resource managers are also concerned about the risk of neonicotinoids to conservation efforts for the monarch butterfly (Danaus plexippus) and need additional data to help estimate risk for wild monarch butterflies exposed to those insecticides. In the present study, monarch butterfly larvae were exposed in the laboratory to clothianidin via contaminated milkweed plants from hatch until pupation, and the effects upon larval survival, larval growth, pupation success, and adult size were measured. Soils dosed with a granular insecticide product led to mean clothianidin concentrations of 10.8 – 2193 ng/g in milkweed leaves and 5.8 – 58.0 ng/g in larvae. Treatment of soils also led to clothianidin concentrations of 2.6 – 5.1 ng/g in adult butterflies indicating potential for transfer of systemic insecticides from the soil through plants and larvae to adult butterflies. Estimated LC50s for total mortality (combined mortality of larvae and pupae) and EC50 for larval growth were variable but higher than the majority of concentrations reported in the literature for clothianidin contamination of leaves.

This dataset shows the effects of herbicides and one fungicide (detected in Great Barrier Reef catchments) on the specific growth rates (from cell density data) of the microalgae Tisochrysis lutea during laboratory experiments conducted from 2018-2019. The aim of this project was to apply standard ecotoxicology protocols to determine the effects of Photosystem II (PSII), alternative herbicides and one fungicide on the growth of the marine microalgae Tisochrysis lutea. Growth bioassays were performed over 3-day exposures using pesticides that have been detected in the Great Barrier Reef catchment area (O'Brien et al., 2016). These toxicity data will enable improved assessment of the risks posed by PSII and alternative herbicides as well as the fungicide propiconazole to microalgae for both regulatory purposes and for comparison with other taxa. Methods: The haptophyte Tisochrysis lutea (formerly known as Isochrysis galbana)(Grant etal. 2017) (strain CS-177) was purchased from the Australian National Algae Supply Service, Hobart (CSIRO). Cultures of T. lutea were established in EDTA-free Guillard’s f/2 marine medium (Trenfield et al. 2015) (1 ml L-1 of f/2 medium in autoclaved natural seawater). Cultures were maintained in sterile 500 ml Erlenmeyer flasks as batch cultures in exponential growth phase with weekly aseptically transfers of 10 ml T. lutea suspension to 300 ml f/2 medium. Culture were maintained at 28 ± 1°C, 33 ± 1.5 psu and under a 12:12 h light:dark cycle (80 – 100 µmol photons m–2 s–1). Pesticide stock solutions were prepared using PESTANAL (Merck) analytical grade products (purity greater than or equal to 98%): diuron (CAS 330-54-1), metribuzin (CAS 21087-64-9), tebuthiuron (CAS 34014-18-1), bromacil (CAS 314-40-9), propazine (CAS 139-40-2), simazine (122-34-9), imazapic (CAS 104098-48-8), haloxyfop-p-methyl (CAS 72619-32-0), 2,4-D (CAS 94-75-7), MCPA (CAS 94-74-6), fluroxypyr (CAS 69377-81-7) and propiconazole (CAS 60207-90-1). The selection of pesticides was based on application rates and detection in coastal waters of the GBR (Grant et al. 2017, O’Brien et al. 2016). Pesticide stock solutions (100 – 1,000 mg L-1) were prepared by dissolving aliquots of the pure compounds in ultrapure water using clean, acid-washed (5% nitric acid) glass screw-top containers. Simazine, tebuthiuron and haloxyfop-p-methyl were dissolved using the carrier dimethyl sulfoxide (DMSO) (less than or equal to 0.02 % (v/v) in exposure solutions). Diuron, imazapic, metribuzin, bromacil, 2,4-D, propazine, MCPA, fluroxypyr and propiconazole were dissolved in acetone (less than or equal to 0.01 % (v/v) in exposure). Stock solutions were stored refrigerated and in the dark. Tests were conducted as previously described (Trenfield et al. 2015). Cultures of T. lutea were exposed to increasing concentrations of individual pesticides over a period of 72 h. Inoculum was taken from cultures in exponential growth phase (4-d old culture) and starting cell density assessed using a haemocytometer. For each treatment, a total volume of 250 mL test media was prepared in a clean, acid-washed 500 mL Schott bottle. Test media consisted of filtered (0.45 µm) seawater spiked with the respective pesticide stock, quarter strength EDTA-free f/2 media as nutrient source and T. lutea at a starting density of 3x103 or 1x104 cells mL-1. In each toxicity test, the response (specific growth rate of the culture) of the treatments exposed to pesticide were assessed against a seawater control group (no herbicide). For each test, 2 – 3 replicate 125 mL Erlenmeyer flasks (50 mL test volume) were assessed. Flasks were incubated at 27 – 29.0°C under a 12:12 h light:dark cycle (80 – 100 µmol photons m–2 s–1). After 72h, sub-samples (7 ml) were taken from each flask and cell densities measured using a flow cytometer (BD Accuri C6, BD Biosciences, CA, USA). Specific growth rates (SGR) were expressed as the logarithmic increase in cell density from day i (ti) to day j (tj) as per

This dataset shows the effects of three insecticides (diazinon, fipronil, imidacloprid) and two fungicides (chlorothalonil, propiconazole) on larval metamorphosis in the coral Acropora tenuis. These five pesticides have been detected in the Great Barrier Reef lagoon and/or catchments. Settlement assays were conducted in Nov-Dec 2016 and Nov 2017. The aim of this research is to add toxicity data for inclusion into water quality guidelines. In order to improve water quality guidelines and subsequent risk assessments for pesticides in tropical marine ecosystems, the current study investigated the effects of three insecticides (diazinon, fipronil, imidacloprid) and two fungicides (chlorothalonil and propiconazole) on larval settlement and metamorphosis of the common reef-building coral Acropora tenuis larvae following 48 h exposures. Concentration-response curves were plotted to estimate no effect concentration (NEC) and effect concentration (ECx) values that inhibited larval settlement by 10% and 50% (EC10 and EC50, respectively). NEC is the concentration below which the pesticides are not expected to cause a reduction in larval metamorphosis. Methods: Gravid colonies (25-40 cm diameter) of the coral Acropora tenuis (Dana, 1846) were collected from 4 – 8 m depth in November 2016 from Trunk Reef (18°18.2’ S, 146°52.2’ E) and in November 2017 from Falcon Island (18°46’ S, 146°32’ E), GBR under Great Barrier Reef Marine Park Authority Permit G12/35236.1. Colonies were transported to the National Sea Simulator at the Australian Institute of Marine Science (AIMS) in Townsville and maintained in 1700 l flow-through holding tanks until spawning. Temperatures were held at 26-27°C, which was equivalent to the water temperature at the collection site. Gametes were collected from 8 parental colonies on each occasion, fertilised and symbiont-free larvae were cultured at approximately 500 larvae L-1 in 500 L flow-through tanks (Negri and Heyward, 2001, Nordborg et al., 2018). Larvae were competent to settle after 5 d and we used 7-10-day old A. tenuis larvae, each 800-1000 µm in length for consistency in the pesticide exposure experiments. The five pesticides in this study were > 98% pure and purchased from Sigma-Aldrich (NSW, Australia). Stock solutions (5 mg l-1) of all pesticides were dissolved in dimethyl sulfoxide (DMSO, final concentration < 0.01% (v/v) in exposures) and prepared in milli-Q water. A. tenuis larvae were exposed to diazinon (2.62 – 638 µg l-1), fipronil (1.57 – 1144 µg l-1), imidacloprid (3.88 – 947 µg l-1), chlorothalonil (0.69 – 507 µg l-1) and propiconazole (8.42 – 2053 µg l-1). Pesticide analyses were done by The University of Queensland, Queensland Alliance for Environmental Health Sciences (QAEHS), Woolloongabba, Australia. Static exposures were conducted in 20 mL glass scintillation vials containing 12-14 larvae made up to 10 mL filtered seawater (0.5 µm) with 6-7 concentrations (per pesticide) and 6 replicate vials per concentration. All tests included solvent controls containing identical concentrations of DMSO carrier. Seawater and solvent carrier controls were run in 12-18 replicate vials. Copper (CuCl2) was used as a reference toxicant at 6 concentrations between 1.12 – 36 µg L-1 and 6 replicate vials per concentration. Glass vials were transferred in random positions within a refrigerated shaking incubator (TLM-530, Thermoline Scientific) at 70 RPM to maintain gentle water movement which prevents larvae from attaching and undergoing metamorphosis in the containers (Negri et al., 2016). Larvae were exposed under a light intensity of approximately 60 µmol photons m-2 s-1 (12:12 h L:D cycle) and at 26.7 ± 0.7 °C (range). Vials were re-randomised at 24 h. After 48 h exposure larvae and treatment water were transferred into 6-well polystyrene culture plates (Nunc, NY, USA) and returned to the incubator but without water movement. Metamorphosis was initiated by the addition of crustose coralline algae (CCA) extract

This dataset shows the effects of of the insecticide imidacloprid and the fungicide propiconazole on larval development of the acorn barnacle Amphibalanus amphitrite experiments conducted in 2018 and 2019. The aim of this project was to apply standard ecotoxicology protocols to determine the effects of the insecticide imidacloprid and the fungicide propiconazole on larval development rate of the acorn barnacle Amphibalanus Amphitrite. Larval development bioassays(4-d exposures) were conducted using a fungicide and insecticide that have been detected in the Great Barrier Reef catchment area (O'Brien et al., 2016). These toxicity data will enable improved assessment of the risks posed by pesticides to marine crustaceans for both regulatory purposes and for comparison with other taxa. Methods: Pesticide stock solutions were prepared using PESTANAL (Merck) analytical grade products (purity greater than or equal to 98%): imidacloprid (CAS 138261-41-3) and propiconazole (CAS 60207-90-1). This selection was based on application rates and detection in coastal waters of the GBR (O’Brien et al., 2016; Grant 2017). Pesticide stock solutions (100 – 1,000 mg L-1) were prepared by dissolving aliquots of the pure compounds in ultrapure water using clean, acid-washed (5% nitric acid) glass screw-top containers. Acetone was used to dissolve the imidacloprid and propiconazole (less than or equal to 0.01 % (v/v) in exposure solutions). Stock solutions were stored refrigerated and in the dark. Broodstock barnacles had been grown for several generations in the AIMS-NT aquaria facility (originally sourced from Darwin Harbour – 12°26'57.48"S, 130°51'7.51"E). Broodstock were fed freshly hatched brine shrimp (Artemia salina) and live rotifers daily. Broodstock were spawned as previously described (van Dam et al., 2016) and nauplii collected. Tests were conducted as previously described (van Dam et al., 2016). Nauplii were exposed in a custom-designed experimental test system that allowed for constant movement of the exposure media. The system consisted of a series of silanized glass funnels in which nauplii were exposed to increasing concentrations of imidacloprid or propiconazole and tested against control nauplii. Generally, a total of 24 funnels were used for 7 treatment concentrations and a control group, thus allowing for 3 replicate funnels per treatment. Each treatment vessel contained 100 mL exposure media, 50 newly released stage II nauplii and 1 x 107 cells of rinsed Chaetoceros muelleri. Every 24 h, 1 x 107 cells of rinsed C. muelleri were added to each funnel. After 96 h exposure, funnel contents were drained over a 150 µm nitrile mesh. The mesh was examined under a stereomicroscope and the number of cyprids and settled larvae scored. Quality control criteria (> 70% survival in control group) for test acceptability were met for each test used to derive toxicity estimates. Treatment effects were quantified by the percentage successful transition to cyprid in treatment groups relative to controls. Following prescribed statistical procedures (OECD 2006) the R package DRC (R-project 2015, Ritz & Streibig 2005), was used to model the test data and calculate toxicity estimates. Regression models evaluated included log-logistic and Weibull models of different levels of parametrisation. Model comparisons were conducted using the Akaike Information Criterion (AIC) and models that best described the data were applied to approximate pesticide concentrations eliciting 10 and 50% inhibition of successful transition relative to control animals (EC10 and EC50, respectively). The associated 95% confidence limits were estimated using the delta method. Format: The dataset is summarised in one file named ‘Amphibalanus amphitrite pesticide toxicity data_eAtlas.xlsx’ Data Dictionary: The excel spreadsheet has one tab for each pesticide. The last tab of the dataset shows the measured (start and end of test) water quality (WQ) parameters (pH, salinity, dissolved

This data set consists of 96-hour survival of the mayfly Neocloeon triangulifer exposed to a variety of major ion (sodium, potassium, calcium, magnesium, chloride, sulfate, bicarbonate) single salts, binary, and trinary mixtures, gluconate salts, and the organic molecule D-mannitol. Mayflies were less than 24-hours old at the beginning of tests. Mixtures consisted of pairs with either like anions or like cations. One trinary mixture was tested (sodium, potassium, and magnesium chloride salts). Mixture tests were designed to investigate potential for independent action of ions, which could help to identify potential toxicity mechanisms. Data set include tabular data defining the test treatments, and presenting survival of exposed mayflies, associated water quality measurements, and analytical validation of ions concentrations.

A set of experiments was conducted to determine the dietary clothianidin exposures that cause prepupal mortality in the absence of other adverse effects. Monarch larvae were raised from hatch to pupae on clothianidin contaminated swamp milkweed plants. Larval growth, larval survival, and prepupal survival were monitored throughout the experiments in which the exposures ranged from 1.4 – 2,793.1 ng/g leaf. Exposures of 5.4 – 46.9 ng/g leaf resulted exclusively in prepupal mortality while higher exposures of 1,042.4 – 2,793.1 ng/g leaf resulted exclusively in larval mortality. An LC50 and LC10 of 37 and 6 ng/g, respectively, were estimated based on prepupal mortality.
