“…Effects of glyphosate on somatic and ovarian growth, as well as of glyphosatebased formulations on ovarian growth and immune status of freshwater and estuarine crab species were reported (Hong et al, 2017;Avigliano et al, 2018;Canosa et al, 2018). Toxicities have extensively been reported for fish, including the zebrafish D. rerio, on which both glyphosate (Armiliato et al, 2014;Lopes et al, 2014;Uren Webster et al, 2014) and its formulated products (Bridi et al, 2017;Sulukan et al, 2017) were found to exert acute toxicity through inhibited carbonic anhydrase activity due to oxidative stress (production of reactive oxygen species), cellular apoptosis, effects on locomotor activity and aversive behavior, as well as reproduction disorders, deteriorating sperm quality, embryotoxicity malformations, and other endocrine disruption symptoms. Another study found carp (Cyprinus carpio) more sensitive to embryotoxicity of glyphosate at high concentrations (50 mg/l) than zebrafish (Fiorino et al, 2018).…”

“…Existen reportes en animales de experimentación donde otros plaguicidas OF con acción insecticida, como el diazinón y el quinalfos alteran la calidad espermática y la integridad del ADN cuando los espermatozoides son expuestos durante el estadio de espermátida temprana (Ray et al 1992, Piña-Guzmán et al 2005. En el caso del herbicida glifosato, se ha demostrado que, no solo altera los parámetros de calidad y ADN espermáti-cos, sino que se asocia también con la generación de estrés oxidante (Lopes et al 2014, Dai et al 2016. Existen diversas técnicas para evaluar la integridad de la cromatina y el ADN espermático, como la téc-nica de cromomicina A3 (CMA3), el ensayo cometa y SCSA.…”

“…Además, en células somáticas se ha encontrado un aumento en la fragmentación del ADN y presencia de 8-OHdG en cé-lulas mononucleadas procedentes de individuos que residen en poblaciones agrícolas donde se utilizan mezclas de plaguicidas, entre ellos el GLA (Koureas et al 2014, Locia-Morales et al 2014. En otras especies como peces (Danio rerio) se observaron alteraciones sobre la integridad del ADN (Lopes et al 2014). Por otro lado, el mecanismo de alquilación de ácidos nucleicos ha sido ampliamente estudiado en células somáticas donde se ha reportado la formación de aductos de N 7 y O 6 metilguanina, principalmente por la exposición a quinalfos y metamidofos (Eto 1974, Zayed y Mahdi 1987.…”

“…This work demonstrates that even if the effects of a short pulse of glyphosate on microorganisms appear to be limited, the responses of natural microbial communities exposed to glyphosate (and probably other pesticide risks) may vary clearly between different experiments. Silva et al (2014) experiments showed that glyphosate caused harmful effects on the reproductive parameters of Danio rerio males with the drastic fertility reduction caused by the decrease of sperm motility, and the reduction of mitochondrial membrane integrity and function. Authors such as Arenzon (2011) and Bertoletti (2009), reported similar effects as the one presented on Danio rerio (Silva et al, 2014) on Poecilia reticulata, a species traditionally adopted in ecotoxicological assays in Brazil.…”
