“…Cytotoxicity by oxidative stress by Roundup R has been shown by transcriptomic profiling in carp and zebrafish (Uren Webster and Santos, 2015;Sulukan et al, 2017). Acute toxicity, harmful physiological effects including hepatotoxicity, neurotoxicity, deteriorated sperm counts, early life stage development and DNA-damaging effects have been reported for numerous other fish species as well for sublethal exposures to Roundup R products including Roundup Original R , Roundup Transorb R and Roundup WG R , Garlon R , and other glyphosate-based herbicides (Soso et al, 2007;Cavalcante et al, 2008;Guilherme et al, 2010Guilherme et al, , 2014aModesto and Martinez, 2010;Shiogiri et al, 2012;Ghisi and Cestari, 2013;Nwani et al, 2013;Marques et al, 2014;Moreno et al, 2014;Navarro and Martinez, 2014;Richard et al, 2014;Sinhorin et al, 2014;Braz-Mota et al, 2015;Menéndez-Helman et al, 2015;Li et al, 2016;de Moura et al, 2017;Sánchez et al, 2017;Gonçalves et al, 2018;Zebral et al, 2018) or POEA (Yusof et al, 2014). Roundup R was found to disrupt 17β-estradiol and reduce glutathione concentration in the liver of the endangered fish species delta smelt (Hypomesus transpacificus) upon 6 h of exposure at levels corresponding to 78 µg/l glyphosate concentrations and above (Jin et al, 2018).…”
