“…Interpolation technique was used to obtain the spatial distribution of groundwater quality parameters for zoning nitrate concentrations across Iran because kriging is known as the best unbiased linear estimator. The output map for mean nitrate concentration (Figure 4 left) shows that high nitrate concentrations in groundwater were observed in the northeast (Khorasan province), northwest (Hamedan (25) and east Azerbaijan provinces (2)), southwest (Fars province (22)) and north (Mazandaran province (24)). The output map of maximum nitrate concentration shows that the highest nitrate concentrations were seen in the northeast (Golestan province (20)), northwest, north and center (Yazd province (27)).…”

“…The relationship between average nitrate concentration and population density, consumption of drinking water and agricultural water uses was obtained using Genetic Algorithm (Gene X Pro Tools ver. 4.0) as: 22 Where A is agricultural water use, D is drinking water, P is population and NO 3 is the mean concentration of nitrates. The R 2 was 0.76 and SD was 0.21.…”

“…They developed a contour map using the nitrate measurements at the specific sampling locations to create contours and isolines through interpolation of data points [21]. Furthermore Ben Aakame et al [22] assessed the physicochemical quality (such as nitrate concentration) of well's water in the region of Northwest of Morocco, which is used in the supply of drinking water for a large population.In another research in this region, long-term assessment of surface and ground waters quality in Tensift region during the period of 2003 to 2012 was investigated[ [23]. Official reports state that water contamination in Iran is caused by agricultural drainage water (87%), sewage (11%), and industrial wastewater (2%).A significant percentage of contaminants in agricultural drainage water are from nutrients(fertilizers) and pesticides [24].…”

Groundwater quality management is important in arid and semi-arid regions, as in Iran. Nitrate (NO 3 -) is a common anion that contaminates groundwater. The present study determined the nitrate concentrations of aquifers in Iran. Data derived from studies in which the nitrate concentration had minimal spatial error at different periods were used for analysis. This included a total number of 2353 nitrate samples taken from wells located in all area of Iran. These were extracted from 82 articles and covered all of provinces. Furthermore, in every region, the average and maximum nitrate concentration were identified and kriging interpolation technique was used to obtain the spatial distribution of groundwater quality parameters by Arc view GIS 10.2 software. The results showed that the nitrate levels in samples from some regions were above the maximum standard level. Nitrate contamination in some regions had increased over the last 10 years. Genetic algorithms were applied to determine the relationship between average nitrate concentration and population density, consumption of drinking water and agricultural water use. The results show that water use in agricultural areas and the subsequent consumption of fertilizer are the main source of groundwater contamination with nitrate in Iran.

“…Several studies have reported pesticide contamination of groundwater in the Saïss Basin region. Radouane et al [24] found that 30% of sampled sites were classified as unsuitable for human consumption, while Aakame et al [25] detected the presence of pesticides in all water samples. Additionally, Berni et al [26] highlighted a high ecological risk associated with the Saïss aquifer due to the presence of pesticides.…”

The Sebou River Basin is vital for Moroccan agriculture, particularly in terms of producing industrial crops, fruits, vegetables, and olive oil. It is especially significant in viticulture, accounting for 80% and 60% of the national production area for wine and table grapes, respectively. However, the prevalence of diseases and pests requires extensive pesticide application in vineyards. This study aims to assess the impact of pesticides used in vineyards on the environment, human health and their associated sustainability. Agro-environmental indicators were evaluated across 30 vineyards covering 1197 hectares. Results show an average treatment frequency of 24.05 applications per growing cycle, the highest among grape-producing countries, with 77.94% being fungicides. The Quantity of Active Substances Indicator (QASI) reveals a high pesticide application rate of 44.60 Kg a.i./ha. Over 50% of chemicals are classified as “hazardous” based on the Environmental Impact Quotient (EIQ). A Pesticide Environmental Risk Indicator model (PERI) identifies three active ingredients with a high Environmental Risk Score (>5). Life Cycle Assessment (LCA) reveals that copper sulfate has significant environmental impacts compared to Mancozeb and sulfur. These findings highlight the extensive use of pesticides in vineyards, posing challenges to long-term sustainable agriculture due to associated environmental and health risks.

Total Fluorescence Fingerprinting of Pesticides: A Reliable Approach for Continuous Monitoring of Soils and Waters

et al. 2017

View full text Add to dashboard Cite

The present work relates to the creation/extension of a database of Total Excitation-Emission and Total Synchronous Fluorescence Matrices (TEEMs and TSFMs) along with optimal Synchronous Fluorescence Spectra (SFS) to fingerprint pesticides widely used in Morocco. This spectrometric multi-component fingerprinting may permit the direct detection of pesticides persisting in soil or water. The objective of the current investigation is to detect four pesticide remains in agricultural soils by applying the spectrometric fingerprinting results. They are the commercial: i) insecticide Axlera 5G (carbamate), ii) fungicide Orsalis 5% SC (triazole), iii) insecticide Force 0,5 G (pyrethrinoid) and iv) insecticide Proclaim 05 SG (non-assigned). The agricultural plantations monitored are located in the great agricultural Doukkala region at the western Atlantic side of Morocco, where these chemicals are in large sale and use.
