| Title | Modeling pesticides in surface runoff: a review of the current status, progress achieved and desirable improvements |
| Abstract | The excessive use of pesticides in agriculture poses a threat to water and environmental quality.
Under Horizon Europe, considering the priorities of the European Green Deal (EGD), research
activities, technological innovation, and investments are needed to contribute to reducing the use
of pesticides, fertilizers, and antimicrobials. In this scenario, there is a need to carry out studies on
the short and long-term effects of the use of pesticides in the agro-environment and on the effect
of mitigation measures. For this purpose, hydrological models are useful tools for the simulation
of the fate and transport of pesticides.
Through a critical review, this study aims to: (i) update the status of the use of the hydrological
models to simulate pesticides coming from diffuse pollution, (ii) Analyze the spatial and temporal
scale of the model applications, (iii) Investigate possible relationships between models and specific
pesticides. The ISI papers were selected based on six keywords were used on Scopus: "pesticides,
model, watershed, hydrology, water quality, diffuse pollutant". After removing articles, not in
English and articles not related to modeling applications, 37 papers were found and analyzed by
constituting a database containing information about the study areas, the pesticides, the model,
and the methodology adopted (I.e. warm-up, calibration, and/or validation). Pesticides were
classified into three categories: herbicides, fungicides, and insecticides.
Results showed that most of the study areas were localized in Europe (55.5%) followed by North
America (22.3%), Asia (13.9%), and South America (8.3%). Soil and Water Assessment Tool was the
most commonly used model with a percentage of 45.95%. Regarding the substances investigated,
herbicides were the most modeled (71.4%) followed by insecticides (18.2%) and fungicides (10.4%).
In particular, among the most commonly modeled herbicides were atrazine, metolachlor,
isoproturon, glyphosate, and acetochlor. Among the insecticides, chlorpyrifos and metaldehyde
were the substances most frequently modeled. Finally, chlorothalonil and tebuconazole were the
most investigated fungicides.
This work will be useful to create an updated guideline to facilitate the water and the landscape
managers in selecting a specific hydrological model to assess the transport and fates of pesticides
and to simulate the effect of potential mitigation practices. |
