“…Our results complement previous attempts to establish methodology and standards for biomonitoring with C. sancticaroli (Moreira- Dornfeld et al 2006;Santos et al 2007;Janke et al 2011;Printes et al 2011and Campagna et al 2013, Richardi et al 2015. The present experiment also contributed to the establishment of simple solutions with low costs of biomonitoring by using in situ assays to complement previous works (Soares et al 2005;Dornfeld et al 2006;Faria et al 2006).…”

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.

Benthic macroinvertebrates are organisms that are recognized as water quality bio-indicators. A wide variety of indices and metrics have been shown to respond to a variety of anthropogenic impacts, usually under a general condition of environmental impairment. The absence of a clear distinction in the relations between specific pollutants and biotic variables is very common and can lead to biased interpretation of biomonitoring. The aims of this research were to test taxonomic and non-taxonomic responses to specific environmental conditions instead to general conditions. For this purpose, we estimated the theoretical toxicity by comparing toxicity values published by EPA with metal concentrations in water and sediments. Then we tested the responses of biological variables to toxicity and other environmental conditions using the linear mixed effects models approach. We generated 32 models considering 24 different biological metrics and indices that were grouped in five levels. Taxonomic and abundance metrics were best predictor than functional or tolerance-based indexes. The strongest model was that which considered subfamily taxonomic resolution responding to Al_w and Cr_s.

“…Their life cycles comprise four phases: ovigerous mass, larva (with ve instars), pupa, and mosquito (Silva et al, 2019). The larva are aquatic sediment diggers and feed on detritus, which often expose them to chemicals via several uptake routes (Campagna et al, 2013).…”

Chironomus sancticaroli (Diptera: Chironomidae) in ecotoxicology: laboratory cultures and tests

et al. 2023

Chironomus sancticaroli is a species restricted to tropical environments, easy to grow and to maintain in laboratory cultures. C. sancticaroli usually has many generations per year, which is an important criteria for selecting a test organism in ecotoxicology. This study aimed to: (1) review the methods for C. sancticaroli cultivate and its use in ecotoxicological tests, (2) establish a laboratory culture of C. sancticaroli, presenting the di culties and discussing the ways to overcome them. The 4th instar larvae was the most used in acute studies, while the 1st instar larvae was the most used in chronic studies; 96 hours and 28 days were the most frequent durations in acute and chronic studies, respectively. The most common endpoints evaluated were organisms' survival and development, and most of the ecotoxicological studies using C. sancticaroli were performed in laboratory. Most of the tested contaminants were of the group of pesticides and these were also the ones that had the most adverse effects on organisms. Most mesocosms with environmental contaminated samples did not show adverse effects on C. sancticaroli. Chronic and eld studies as well as those testing the effects of the mixture contaminants on C. sancticaroli were still de cient. Keeping the laboratory environment and equipment effectively sanitized was important for the success of the cultivate as well as maintain stabilized conditions of temperature, photoperiod, physical, chemical and biological water quality in cultures. HighlightsChironomus sancticaroli is a tropical macroinvertebrate. C. sancticaroli is usually used in ecotoxicological tests.There are many gaps regarding ecotoxicological tests standards for C. sancticaroli.This study provides recommendations and details to overcoming culture issues.
