Special Issue Information

Dear Colleagues,

Pesticides comprise a powerful tool in agriculture, used to satisfy the worldwide need for food. Authorities establish regulations and guidelines regarding the authorization, use, and monitoring of pesticides to protect the environment and ensure human safety. However, the indiscriminate misuse of these chemicals raises a special concern regarding the levels that occur in the environment and the degree that their occurrence, in total, endangers the safety of our ecosystem. The pesticides’ fate and behavior in the environment depends on several parameters such as their physicochemical properties, the agricultural practice applied, the meteorological conditions, biotic processes and others. Simulation models are used to predict the environmental concentrations, which are subsequently used for the ecotoxicological risk assessment and eventually for the establishment of safe regulatory limits. In addition to this, there is an increased interest in the use of available monitoring data of pesticides in the environment for the performance of the risk assessment and management.

This Special Issue aims to solicit original contributions providing data on the occurrence of pesticides’ residues in soil, sediment, groundwater, surface water, air and biota. The editors encourage submissions that apply different fate models to the calculations or predict environmental concentrations and submissions regarding the identification and quantification of pesticides and their (bio)transformation products in the relevant environmental compartments with high resolution analytical methods. Finally, contributions on the use of monitoring data in the environmental risk assessment and the regulatory procedure for pesticides are welcome. The scope of submission includes original research and review articles on the theme.

Variations in soil pH have been shown to affect mesotrione adsorption, which in turn, may have an impact on crop susceptibility. Therefore, a greenhouse experiment was conducted to evaluate the effect of simulated mesotrione residues on pea crop grown in the typical agricultural soil (gleysol) of north-western Croatia. The soil pH was manipulated to obtain neutral (pH 7.0) and acidic (pH 5.0) values. Simulated mesotrione residues were 1.1, 2.3, 4.5, 9.0, 18, 36 and 72 g a.i. ha−1. Crop visual injuries as well as reductions in chlorophyll fluorescence and aboveground dry biomass were higher at pH 7.0 than at pH 5.0. With increasing mesotrione residues, the reductions in chlorophyll fluorescence ranged from 38.8% to 89.7% at pH 5.0 and from 63.7% to 99.3% at pH 7.0. Compared to chlorophyll fluorescence, the reductions in dry biomass were smaller and ranged from 49.2% to 96.8% at pH 7.0 and from 32.0% to 82.6% at pH 5.0 for the mesotrione residues from 1.1 to 72 g a.i. ha−1. These results indicate that soil pH is an important factor determining the susceptibility of pea crop to simulated mesotrione residues. Full article
