Relationship between pesticide accumulation in transplanted zebra mussel (Dreissena polymorpha) and community structure of aquatic macroinvertebrates

The toxic influence and biodegradation of carbon nanofibers in freshwater invertebrates of the families Gammaridae, Ephemerellidae, and Chironomidae

“…It is known that freshwater insects provide minerals and several vitamins for organisms who eat them. Vitamin and mineral profiles of insects significantly depend on the composition of the insect diet, especially benthic aquatic invertebrates inhabiting the bottom layers of reservoirs, which swallow mineral grains [ 28 ]. In the CON groups of the specimens used in the experiment, we compared the spectra of the intestinal contents with various minerals as shown in Fig.…”

“…Freshwater plants and animals are continuously exposed to anthropogenic toxicants, which leads to their death and destruction of the biocenosis [ [23] , [24] , [25] , [26] ]. Macroinvertebrates play a key role in the trophic chain of freshwater ecosystems, and they are excellent indicators of water quality, especially larvae of amphibiotic insects due to the high sensitivity to any type of pollution [ [27] , [28] , [29] ]. Moreover, macroinvertebrates play a pivotal role in the transformation of substances and energy in water bodies, they create an environment for the aquatic inhabitants and participate in the enhancement of water quality [ 30 , 31 ].However, there are few studies of carbon nanomaterial toxicity in freshwater invertebrates [ [32] , [33] , [34] ], and, to the best of authors’ knowledge, still there is no study of CNFs influence on freshwater invertebrates.…”

Species Sensitivity Distribution of Dichlorvos in Surface Water Species

“…Approximately 14% of the values listed in Table 3 had a concentration >1.00 μgL -1 . Additionally, the ndings of dichlorvos in freshwater organisms from Argentina and Belgium indicate not only its presence in water bodies but also the presence in biological matrices [60,61].…”

Mesocosmos como modelo experimental na avaliação da ecotoxicidade aquática

“…Em experimentos que utilizam modelos de mesocosmos in situ, realizados em uma área do próprio ambiente, é possível utilizar os organismos presentes no local onde o sistema foi instalado. Nestes estudos, comumente são utilizadas comunidades planctônicas e bentônicas que possuem grande número de indivíduos (Bashnin et al, 2019;Shangguan et al, 2017). Outra possibilidade é a inserção de organismos-modelo cultivados em laboratório dentro do sistema teste (Egea-Serrano and Tejedo, 2014).…”
