Hyalella azteca is an important food for many waterfowl. The results of the Microtox test showed that the toxicity of the vegetable-oil-contaminated sediments (about 17–33 g oil/kgdry sediments) increased af-ter 2 weeks incubation and then decreased to near background levels after incubation for 8 weeks under anaerobic conditions. Larvae that start feeding eat the smallest hyalellas and switch to older ones as they grow, simple. After release into the aquatic environment, engineered nanomaterials (ENMs) undergo complex chemical and physical transformations that alter their environmental fate and toxicity to aquatic organisms. , 2006).

Driven by pre-exposure to pesticides, resistance to pyrethroid and organophosphate pesticides has been documented in populations of a nontarget amphipod, Hyalella azteca, in California. The identity of the species has always been a problem, especially because the original description by Saussure (1858) from a "cistern" in Vera Cruz, Mexico, is poor, and the figures are not clear. Test solutions were generated by a modified diluter with an extended (24‐h) equilibration period. This research aims to provide a robust assessment of the impacts of alterations in salinity on the fitness of pyrethroid-resistant and non-resistant H. Likewise, isolation of organisms in different laboratories may contribute to significant genetic differentiation among culture populations. Ten chemicals were tested at the U.
