Toxicity testing with Antarctic species is required for risk assessment of fuel spills in Antarctic coastal waters. The lethal and sub-lethal (movement behaviour) sensitivity of adults and juveniles of the Antarctic amphipod Paramoera walkeri to the water accommodated fractions (WAF) of three fuels were estimated in extended duration tests at -1°C to 21 d. Response of P. walkeri for lethal hydrocarbon concentrations was slow, with LC50s first able to be estimated at 7 d for adults exposed to Special Antarctic Blend diesel (SAB), which had the highest hydrocarbon concentrations of the three fuel WAFs. Juveniles showed greater response to marine gas oil (MGO) and intermediate residual fuel oil (IFO 180) at longer exposure durations and were most sensitive at 21 d to IFO 180 (LC50 = 12 µg/L). Adults were initially more sensitive than juveniles; however, at 21 d juveniles were more than twice as sensitive as adults to SAB (LC50 = 153 µg/L and 377 µg/L respectively). Significant effects on movement behaviour were evident at earlier time points and lower concentrations than was mortality in all three fuel WAFs, and juveniles were highly sensitive to sub-lethal effects of MGO. These first estimates of Antarctic amphipod sensitivity to diesel and fuel oils in seawater contribute to development of ecologically relevant water quality guidelines for management of hydrocarbon contamination in the region.

Attention Score in Context
Attention Score in Context
This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 26 August 2017.
All research outputs
#22,970,974
of 33,992,632 outputs
Outputs from Environmental Toxicology & Chemistry
#5,172
of 6,852 outputs
Outputs of similar age
#224,033
of 351,099 outputs
Outputs of similar age from Environmental Toxicology & Chemistry
#31
of 74 outputs
Altmetric has tracked 33,992,632 research outputs across all sources so far. This one is in the 30th percentile – i.e., 30% of other outputs scored the same or lower than it.
So far Altmetric has tracked 6,852 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 7.0. This one is in the 20th percentile – i.e., 20% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 351,099 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 33rd percentile – i.e., 33% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 74 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 52% of its contemporaries.
