TLDR
Atrazine was genotoxic and mutagenic for D. minutus in a dose-sensitive manner, dependent on larval developmental stages, and replicating biomonitoring studies using different species to represent ecosystems' environmental impacts is suggested.About:

An overview of the potential impacts of atrazine in aquatic environments: Perspectives for tailored solutions based on nanotechnology
Felícia Pereira de Albuquerque,Jhones Luiz de Oliveira,Viviane Moschini-Carlos,Leonardo Fernandes Fraceto +3 more
TL;DR: This review addresses aspects related to the impacts of atrazine in the environment, with focus on its effects on aquatic species, as well as the potential use of nanoencapsulation to decrease the impacts.

TL;DR: The use of vertebrate models and their role in environmental biomonitoring will be discussed as well as the comparison of the use of the comet assay in vertebrate and human models in line with ethical principles.
Journal ArticleDOI
Biochemical and histological effects of sub-chronic exposure to atrazine in crayfish Cherax destructor.
TL;DR: Evidence is provided that environmental concentrations of ATR produce negative effects on freshwater crayfish and some observed effects persisted after 14-days recovery in ATR-free water.

Biomarkers at different levels of organisation after atrazine formulation (SIPTRAN 500SC®) exposure in Rhinella schineideri (Anura: Bufonidae) Neotropical tadpoles.
Juan Manuel Pérez-Iglesias,Lilian Franco-Belussi,Lilian Franco-Belussi,Guillermo Sebastián Natale,Classius de Oliveira +4 more
TL;DR: This study is the first to use several widely differing endpoints at different ecotoxicological levels in a comprehensive manner for assessment of the effects of environmental stressors in order to determine the health status of Neotropical anuran species and establishes a foundation for future ecological assessments.

Genotoxic Evaluation in Tadpoles Associated with Agriculture in the Central Cerrado, Brazil.
Rinneu Elias Borges,Lia Raquel de Souza Santos,Marcelino Benvindo-Souza,Richelle Sousa Modesto,Rhayane Alves Assis,Classius de Oliveira +5 more
TL;DR: In situ data of Dendropsophus minutus, Physalaemus cuvieri, and Scinax fuscovarius collected in soybean/corn and conservation units in the Brazilian Cerrado showed no significant variation in the micronucleus frequency between sites, but only the reniform cells had a higher rate for the agricultural environment.

Journal ArticleDOI
A simple technique for quantitation of low levels of DNA damage in individual cells
TL;DR: Human lymphocytes were exposed to X-irradiation or treated with H2O2 and the extent of DNA migration was measured using a single-cell microgel electrophoresis technique under alkaline conditions and this technique appears to be sensitive and useful for detecting damage and repair in single cells.
Journal Article
A simplified table for staging anuran embryos and larvae with notes on identification
TL;DR: A simplified table adequate for staging "generalized" developmental series will be presented, which is original only to the extent that it is a simplification of those already in existence.

The Comet Assay for DNA Damage and Repair: Principles, Applications, and Limitations
TL;DR: The comet assay (single-cell gel electrophoresis) is a simple method for measuring deoxyribonucleic acid (DNA) strand breaks in eukaryotic cells that has applications in testing novel chemicals for genotoxicity, monitoring environmental contamination with genotoxins, human biomonitoring and molecular epidemiology, and fundamental research in DNA damage and repair.
Journal ArticleDOI
The in vitro micronucleus technique.
TL;DR: In its current basic form the CBMN assay can provide the following measures of genotoxicity and cytotoxicity: chromosome breakage, chromosome loss, chromosome rearrangement, cell division inhibition, necrosis and apoptosis.

Hermaphroditic, demasculinized frogs after exposure to the herbicide atrazine at low ecologically relevant doses.
Tyrone B. Hayes,Atif Collins,Melissa Lee,Magdelena Mendoza,Nigel C. Noriega,A Ali Stuart,Aaron Vonk +6 more
TL;DR: It is hypothesize that atrazine induces aromatase and promotes the conversion of testosterone to estrogen and likely explains the demasculinization of the male larynx and the production of hermaphrodites.
