“…The use of herbicides as a supplementary source of nutrients by degrading communities could explain this stimulation (Kanissery and Sims 2011). Our results highlighted the rapid decrease of each herbicide just after their spraying (Fig.…”

Soil is a primary resource used by mankind to ensure its needs mainly through agriculture. Its sustainability is regulated by the indigenous organisms it contains such as microorganisms. Current agricultural practices employ mixtures of pesticides to ensure the crops yield and can potentially impair these non-target organisms. However despite this environmental reality, studies dealing the susceptibility of microorganisms to pesticide mixtures are scarce. In this context, we designed a 3-month microcosm study to assess the ecotoxicity of realistic herbicide mixtures of formulated S-metolachlor (Dual Gold Safeneur ® ), mesotrione (Callisto ® ), and nicosulfuron (Milagro ® ) on the abundance, the diversity, and the activities of microorganisms from a "clay/organic matter-rich" soil, with a particular attention given to N-cycle communities. These communities appeared to be quite resistant to realistic mixtures even if transient effects occurred on the N-cycle-related communities with an increase of ammonification and an inhibition of nitrification as a short-term effect, followed by an increase of denitrification and an accumulation of nitrates. As nitrates are known to be highly leachable with a strong pollution potential, intensive studies should be carried out at field level to conclude on this potential accumulation and its consequences. Moreover, these data now need to be compared with other agricultural soils receiving these herbicide mixtures in order to bring general conclusion on such practices.

“…Biostimulation of herbicides with the addition of carbon can be a direct effect of increased populations or the indirect result of changes to nutrient availability and thus the nature of effect can vary depending upon chemical and nutrient properties of the environment . In the present study, unamended slurry samples contained, on an average, 5.5 × 10 5 bacteria/mL of sample.…”

The fate of simazine and diuron during natural treatment processes occurring in aquifers during managed aquifer recharge (MAR) was evaluated by batch tests in conditions relevant to MAR using urban storm water. The tests were performed with aquifer sediment and wetland treated storm water under aerobic and anoxic geochemical conditions, with and without a carbon source amendment to assess the degradation of these herbicides. The aerobic conditions were suited for the relatively rapid degradation of the positive control 17β‐estradiol with a half‐life of 3.8–4.5 days and a much slower decay of simazine (30–32 days) and diuron (35–41 days). The study also showed that significant attenuation of simazine can be achieved through biodegradation under nitrate reducing conditions in aquifer sediments, with a similar half‐life (26–30 days) to the aerobic condition. The biodegradation half‐life of diuron under nitrate reducing conditions was long (91 days), but carbon supplement (20 mg C/L) halved it to 41 days. Significant attenuation of simazine and diuron in aquifers may be achievable, if sufficient residence time (e.g. at least a year) is allowed in the subsurface in aquifer storage, transport and recovery schemes.

“…One approach for enhancing biodegradation in soil is the addition of electron acceptors, such as oxygen or nitrate, in order to stimulate indigenous microbial populations (Kanissery and Sims, 2011). Adding oxygen can enhance the aerobic biodegradation of phenoxy acids at high concentrations (45 µg L -1 ) in anaerobic aquifer materials emanating from phenoxy acid-contaminated point sources (Tuxen et al, 2006b).…”
