“…simulation studies [43,68] that suggest a population could be exposed to toxic pesticide drift when the surrounding crop fields reach a certain threshold, without taking wind patterns into account. However, this result is fully consistent with the predictions of other studies [41,50,67] that imply the dispersion of organophosphate pesticide vapors emitted at the time of spraying is primarily dependent on the prevailing weather conditions, particularly wind patterns (speed and direction). According to the findings, the increased drift of pesticides into Springfield's urbanagricultural interface communities was caused by the presence of four main air mass groups, originating from five directions.…”

“…This could be attributed to the fact that only 0.136% of the total quantity of organophosphate pesticide used was transformed into small particles (aerosols), and about 10% of the overall quantity of the organophosphate pesticide evaporated. These findings were based on droplet size distributions obtained through multiple AgDRIFT examinations and are consistent with the results of other studies [41,67].

“…Atmospheric models are capable of analyzing a wide range of spray drift situations arising from agricultural applications and off-site deposition of pesticide chemical compositions [36][37][38]. These mathematical models, such as AGricultural DISPersal (AgDISP), AgDRIFT, CALPUFF, and Atmospheric Dispersion Modelling System (ADMS), can estimate spray drift deposition downwind from various application techniques [39][40][41][42][43][44]. Organophosphate substances are a varied category of chemicals utilized in the agricultural and industrial sectors.…”

According to estimates from the World Health Organization (WHO), organophosphate pesticides are responsible for approximately 300,000 deaths worldwide. In the United States, documented cases of organophosphate pesticide exposure number around 8000, with a small number of fatalities occurring annually. The health risks associated with these pesticides affect those living in agricultural areas, as well as farmers and pesticide applicators. Despite the intervention of government agencies in Illinois to regulate pesticide application, studies have shown that these pesticides remain present in the soil, crops, water, and air. Urban–agricultural interface communities around Sangamon County exhibit significant levels of air pollution due to pesticide spray drift, although the lack of reliable pesticide data poses a challenge in estimating the extent of the problem. Therefore, developing novel strategies to reduce the impact of pesticides on environmental health is a critical and effective research area. Currently, new, dependable models and methods are being developed to calculate spray drift and mitigate its effects. The primary objective of this study was to investigate whether and to what extent organophosphate pesticide spray drifts into urban–agricultural interface communities in Sangamon County, Illinois. To achieve this, the current study employed an integrated approach that combined the capabilities of the HYSPLIT and AgDRIFT models to evaluate organophosphate pesticide spray drifting at both the field- and county-level scales. In the absence of precise pesticide quantity data, this novel approach allowed for field simulations within identified exposure drift zones. The preliminary findings indicate that all residential areas close to agricultural areas are at risk of pesticide drift, as buffer zones do not exceed 25 m. Furthermore, of the 34 water bodies (rivers, lakes, streams, and drains) in the 30,200-acre study region, 12 are within the high-drift zone for pesticide spray drift from corn and soybean fields. Finally, the potential for organophosphate pesticide drift was present in approximately 106 buildings, covering an area of 10,300 km2.

Pesticides enter surface and ground waters not only from agricultural lands, but also from the plants, where these substances are produced and packed. Thus, the problem of wastewaters produced by these plants must be solved. This work is devoted to the development of high performance membranes for pressure-driven processes, which would remove pesticides from water and give a possibility to use the concentrate further. Polyamide (PA) and polyvinylidene fluoride (PVDF) microfiltration membranes as well as polyacrylonitrile (PAN) ultrafiltration membrane were modified with hydrated zirconium dioxide (HZD) by a deposition of ion exchanger from sol with ammonia vapour directly in pores of the polymer. The membranes were investigated with SEM method, energy dispersive and FTIR spectra were also recorded. HZD in active layer as well as the products of PA or PAN hydrolysis enhance hydrophilicity of the membrane surface: for instance, the contact angle of water decreases from 69° to 43° for the PA sample. Water test followed by calculation using the Hagen-Poiseuille equation showed a 2–3 times decrease in pore size of the modified membranes comparing with pristine materials. Selectivity of HZD-containing membranes reaches 90–96 % towards bowine serum albumin, and exceeds 99 % in the case of quizalofop-p-ethyl. The highest permeate flux (196 l m–2 h–1bar–1) has been found for the HZD-containing PVDF sample. The pesticide concentration in the permeate was 0.0002–0.008 mg l–1. The posttreatment of the permeate involved adsorption on biochar under dynamic conditions. The method of liquid chromatography showed that after the passage through the column, no pesticide was detected in the permeate or its content was lower than maximal allowable concentration for surface water (0.0001 mg l–1).

Pesticide exposure poses significant environmental and human health concerns, particularly given its extensive use in agricultural activities. The assessment of pesticide risks is a multifaceted and resource-intensive process, often requiring time-consuming toxicity studies. In response to this challenge, advanced computational models, remote sensing, and GIS (geographic information systems) have emerged as efficient and precise tools for evaluating pesticide exposure risks. This comprehensive review aims to provide an in-depth examination of the latest research methodologies for assessing the risks associated with pesticide exposure and their practical applications. These methodologies encompass the assessment of pesticide exposure in air, soil, and water, offering a comprehensive understanding of potential environmental pathways. The paper also delves into the effective utilization of these tools for pesticide risk assessment and examines the potential implications of their findings. The approaches outlined in this review hold promise for a thorough and insightful assessment of pesticide risks and are positioned to equip researchers and policymakers with valuable knowledge to mitigate the impacts of pesticide exposure on human health and the environment.
