“…The toxicity study of green synthesized nanoparticles was tested against fourth instar larvae chironomus costatus , which was collected from same habitat of mosquito larval collection site. The choice of these organisms is due to its importance in ecological dynamics of aquatic ecosystems and these larvae are bio indicators in studies of monitoring water quality [ 36 ]. The importance in analysis of toxicity studies using these synthesized nanoparticles is due to what kind of impacts, which have been created in water bodies like efficiency of biodegradability and other such a factors.…”

Chironomid substrate—specific associations regarding the nature (organic—inorganic) and stability (stable—unstable) of different habitats were investigated at two low order Patagonian streams, during high and low water periods. Nant y Fall and Glyn rivers were visited twice (October 2007 and March 2008) and seven different habitat types were identified. A total of 60 samples were collected using a Surber sampler (0.09 m -2 and 250 µm) and a set of 23 environmental descriptors including physicochemical parameters and different fractions of particulate organic matter were assessed. 35 Chironomidae taxa were recorded with Orthocladiinae (20), Chironominae (7), and Podonominae (4) being the most well—represented subfamilies. Paratrichocladius sp. 1, Parapsectrocladius sp. 2, Parametriocnemus sp. 1, Pseudochironomus sp., and Rheotanytarsus sp. were the most abundant taxa. According to the relative preference index, at least 14 taxa showed strong affinity for a particular substrate. The structurally complex macrophyte Myriophyllum quitense supported 11 taxa compared with only five taxa found on the less complex Isoetes savatieri. Generally, stable substrates (boulders, cobbles, and rooted plants) supported significantly higher chironomids richness, abundance, and diversity than unstable ones (gravel—sand). Canonical correspondence analysis revealed that detritus (leaves, seeds, and biomass), macrophyte biomass, and secondarily hydraulic variables had high explanatory power on chironomids species composition and structure. This work suggests that more complex substrates showing persistence in the temporal dimension supported a diverse array of chironomids, meaning that the maintenance of natural habitat heterogeneity is essential for the community. Land—use practices having significant effects on ecological stream attributes such as increased turbidity, sediment deposition, and runoff patterns will alter assemblages. Understanding environmental associations of the Chironomidae assemblage at the habitat scale is significant for conservation purposes and for the management of low order streams in Patagonia.

“…The lethal and sublethal effects of metal pollution on Chironomus larvae were recorded by ecotoxicological (Roman et al 2007;Di Veroli et al 2012) and field studies (Cortelezzi et al 2011;Di Veroli et al 2014). Different types of sublethal effects have been reported as the result of several laboratory assays using Chironomus.…”

“…Different types of sublethal effects have been reported as the result of several laboratory assays using Chironomus. Among the previously reported sublethal effects, it must be mentioned that morphological effects (Cortelezzi et al 2011;Di Veroli et al 2014) and energetic effects are also related to the developmental (Péry et al 2003), physiological (Sérvia et al 2006) and genetic effects (Jeppe et al 2014;Planelló et al 2015). Dornfeld et al (2006) conducted a pioneering in situ assay with C. sancticaroli larvae.…”

The Cantareira Complex is one of the most important water supplies of the metropolitan region of São Paulo, Brazil. Previously, it was demonstrated that the sediments in this complex were polluted with metals and that Paiva Castro Reservoir-the last reservoir in the sequence, which receives water from the five previous reservoirs-was the reservoir with the greatest concentration of pollutants. Based on field data, it was noticed that copper concentrations in sediments were related to morphological alterations in chironomids. The present study provides novel monitoring methods and results for the complex by isolating the environmental and biological sources of variation. An adaptation of the in situ assay proposed by Soares et al. (Arch Environ Contam Toxicol 49:163-172, 2005), which uses a native tropical Chironomus species and low-cost materials, is also provided. The aim of this study was to isolate the effects of sediments from Paiva Castro on controlled populations of C. sancticaroli larvae using an in situ assay. A seven-day experiment was performed in triplicate. Third instar larvae were inoculated in chambers containing sediments from two distinct regions of Paiva Castro reservoir and a control site with sand. Five biological responses were considered: mouthpart alterations, larval length, width of cephalic capsule, mortality and total damage. The results suggest the effects of sediment toxicity on larvae include a reduction in length and a higher occurrence of total damage.
