“…Atrazine concentrations can exceed the general quality standard for surface and drinking water (5 µg l −1 ) (Giroux, 2015). Values ranging from 9 to 25 µg l −1 in Europe (Croll, 1991;Legrand et al, 1991), 87 to 100 µg l −1 in North America (Steinheimer, 1993;Graymore et al, 2001), and up to 150 µg l −1 in Australia (Graymore et al, 2001) have been reported. Although it has been proposed an acute toxicity threshold value of 20 µg atrazine l −1 , (Diana et al, 2000), under concentrations lower than 20 µg l −1 , atrazine was reported to cause sub-lethal effects in various aquatic organisms such as unicellular algae (DeLorenzo et al, 2001).…”

HIGHLIGHTS• We reviewed the interaction between light, temperature and herbicides on algal and cyanobacterial physiology.• Temperature is the main factor affecting herbicide toxicity to algae and cyanobacteria.• Changes in light environment may modulate the effects of photosynthesis-targeting herbicides.Important interactions between climatic parameters and herbicide toxicity have been discussed in the literature. As climate changes are expected to influence the growth conditions of aquatic photosynthetic organisms over the next century by modifying the physicochemical parameters of the environment (such as temperature and incident light characteristics), the following questions arise: How will variations in climatic conditions influence herbicide toxicity in algae and cyanobacteria? Are these coupled effects on aquatic photosynthetic organism physiology antagonistic, additive, or synergistic?We discuss here the physiological responses of algae and cyanobacteria to the combined effects of environmental changes (temperature and light) and herbicide exposure. Both temperature and light are proposed to influence herbicide toxicity through acclimation processes that are mainly related to cell size and photosynthesis. Algal and cyanobacterial responses to interactions between light, temperature, and herbicides are species-specific, making it difficult today to establish a single model of how climate changes will affect toxicity of herbicides. Acclimation processes could assure the maintenance of primary production but total biodiversity should decrease in communities exposed to herbicides under changing temperature and light conditions. The inclusion of considerations on the impacts of environmental changes on toxicity of herbicides in water quality guidelines directed toward protecting aquatic life is now urgently needed.Keywords: environment, toxicity, hazardous, pollutants, algae, cyanobacteria Gomes and JuneauHerbicides/Climate Changes on PhytoplanktonGraphical Abstract | Changes in temperature and light conditions in water systems over the next century will drive physiological responses of algal and cyanobacterial community to herbicides, by antagonistic, additive, or synergic effects with these pollutants.

“…As a result, the presence of specific pesticides in surface and ground waters is well documented for different agricultural regions of the world (Junk et al, 1980;Hallberg, 1989;Leistra and Boesten, 1989;Frank et al, 1990;Bushway et al, 1991;Gomez de Barreda and Lorenzo, 1991;Legrand et al, 1991;Wade et al, 1998;Garrido et al, 2000;Barbash et al, 2001;Spalding et al, 2003). Among the pesticides detected with certain frequency are atrazine and alachlor (especially the former); this has generally been associated with their widespread use in corn cultivation in all countries.…”

The inputs of atrazine and alachlor herbicides to surface and ground waters from irrigated areas dedicated to corn cultivation in the Castilla-León (C-L) region (Spain) as related to the application of both herbicides were studied. Enzyme-linked immunosorbent assays (ELISA) were used for monitoring the atrazine and alachlor concentrations in 98 water samples taken from these areas. Seventy-nine of the samples were of ground waters and 19 were of surface waters. The concentration ranges of the herbicides detected in the study period (October 1997-October 1998) were 0.04-25.3 microg L(-1) in the surface waters and 0.04-3.45 microg L(-1) in the ground waters for atrazine, and 0.06-31.9 microg L(-1) in the surface waters and 0.05-4.85 microg L(-1) in the ground waters in the case of alachlor. The highly significant correlation observed between the concentrations of both herbicides in the surface waters (r = 0.89, p < 0.001) pointed to a parallel transport of atrazine and alachlor to these waters. A study was made of the temporal evolution of the concentrations of both herbicides, and it was found a maximum recharge of atrazine in the ground waters for April 1998 and of alachlor in October 1997 and October 1998. The temporal evolution of the concentrations of both herbicides in surface waters was parallel. The highly significant correlations observed between atrazine concentrations determined by ELISA and by HPLC (r = 0.92, p < 0.001) and between alachlor concentrations also determined by both methods (r = 0.96, p < 0.001) confirmed the usefulness of ELISA for monitoring both herbicides in an elevated number of samples. Using HPLC, the presence in some waters of the alachlor ethanesulfonate (ESA) metabolite was found at a concentration range of 0.52-4.01 microg L(-1). However the interference of ESA in the determination of alachlor by ELISA was negligible. The inputs of atrazine and alachlor to waters found in this study, especially the inputs to ground waters, could pose a risk for human health considering that some waters, though sporadically, are even used for human consumption.

“…Due to its high mobility, atrazine is frequently detected in surface and ground waters, leading to environmental problems [2,3]. Atrazine has been detected above the recommended levels (0.1 ppb or g/mL) throughout Europe [4,5] and the United States [6,7], and is considered as one of the 33 priority substances of major concern in European waters to be monitored under the Water Framework Directive by the European Commission. Atrazine has also been reported to have endocrine disrupting capabilities [8].…”
