L’étude aborde la mise au point d’un outil SIG décisionnel, basé sur une approche « expert » par logique floue, pour l’évaluation du risque de pollution des eaux de surface et souterraines par les pesticides. Une enquête de terrain combinée aux propriétés physico-chimiques des pesticides, a permis d’identifier la pression polluante agricole liée aux propriétés des pesticides et aux activités anthropiques. La sensibilité des sols au transfert des pesticides vers les eaux de surface et souterraines a été évaluée sur base, d’une part d’une approche par modélisation mécaniste, et d’autre part à partir de l’exploitation de l’information qualitative de la carte des sols, jugée pertinente et non explicitement valorisée par le modèle mécaniste. L’évaluation du risque global a ensuite été réalisée à partir de la construction d’un système expert basée sur la logique floue, qui intègre les évaluations spécifiques aux propriétés des pesticides, aux pratiques culturales et à la sensibilité des sols au transfert des pesticides vers les eaux, en tant que milieu transit-vecteur. L’approche par « logique floue » est un outil robuste qui permet notamment d’agréger de façon uniforme des informations de sources variées, mais aussi d’intégrer l’incertitude (imprécision) associée à certaines données, telles que celles liées aux caractéristiques physico-chimiques des pesticides ou des sols.

Diffuse pollution of water resources due to pesticides uses is a major environmental issue in the European Union, regulated by specific legislations: the Water Framework Directive (Directive 2000/60/EC) and the Thematic Strategy on the Sustainable Use of Pesticides. Solving this environmental problem requires methods and tools for spatial risk analysis, notably at a local scale (agricultural parcel level). This paper presents the first developments of a decision support system aiming to assess surface and ground waters pollution risks due to pesticides uses, based on a Geographic Information System (GIS). Different factors affecting pesticide environmental propagation are taken into account, as for example land use, pesticides properties and application modalities, environment characteristics (soil properties, topography, climate, …) as well as surface and ground waters characteristics. A pesticide emission model is used to assess pesticide leaching or runoff to water resources. The reference scale for risks assessment is the agricultural parcel. The quality of the results obtained will be assessed by comparison with existing water monitoring data and related studies. [less ▲]

In the Walloon Region of Belgium, a commlttee of Intervention has been created to Investigate problems of pesticide contamination of various catchments use for drinking water production. This commlttee Involves the Agricultural Research centre - Wallonla (CRA-W, project coordinator) and sorne University experts. It ls funded by the Société Publique de Gestion des Eaux (SPGE). The diagnosis method, base on the AQUAPLAlNE method (Arvalis - France), conslsts of 4 steps. The first step Is the preparation of diagnosls (at the office) that takes into account the paper r1sk of active ingredients. and thelr uses, the identification of the agrtcultural parcels, the collection of cartographie and numeric data, the description of the hydrogeological and pedological contexts and the study of the meteorologlcal data ln relation with the period of pollution. The second step conslsts of maklng a plot diagnosls (on the field) ta Identify the way of transfer inside the plot and collecting data. At the thlrd step, the people who can apply ppp treatment close to the catchment are met (farmers and city services). Information are coJ!ected on treatments applied and on the state of parcels. Based on the hypathesls of pollution cause, the committee proposes solution to solve the problem. One of the catchment that has been investigated by the commlttee is located at Biesmerée, (Namur province, ln Belglum). A temporally contamination was caused by 4 pesticides: chlortoluron, isoproturon, trifluralln and diflufenlcan. After Investigations, it seems that the pollution was probably due ta the hydrogeologlcal context . As the river Is locally perched over the aqulfer, the presence of Poly-aromatic hydrocarbons (PAHs) could be due ta the Infiltration of surface water inside the catchment or/and to the presence of a sinkhole temparaHy activated durlng river flood period. Infiltration rate has ta be assessed and river bank Impermeabilization Is recommended [less ▲]

Manufacturers of spraying nozzles have established manufacturing tolerances to guarantee the quality of their products. They control, among other things, the new nozzles’ flow rate by comparison with the nominal flow rate. When the deviation exceeds a set limit, the nozzles are rejected. A survey carried out among three manufacturers made it possible to determine the manufacturing tolerances and limits that manufacturers impose upon themselves. The flow rates of 1565 new nozzles collected on the market from these manufacturers were measured on a device developed for this study. Different statistical tests assessed the performances and characteristics of the products. The quality standards announced by the manufacturers were not checked for every nozzle. On average, 20% of the new nozzles exceeded the manufacturing tolerances. The average flow rate of the nozzle sets equalled the nominal flow rate. In practice, the probability distribution of the flow rate of new nozzles should be normal. The dispersion of the new nozzle flow rates was slightly higher than the theoretical one. The quality of the products differed from one manufacturer to another. [less ▲]

The 1st September 1995, the belgian Federal Ministry of Agriculture set up a compulsory control of the sprayers used. All the devices, except for some ofthem, are subjected to a compulsory periodic checking. The practical organsization of the control as well as the test procedure are a bit different from the ones of other European countries. They have been chosen on the basis of educational criteria rather than repressive ones. After 20 months of control, the result is encouraging. More than 13 000 sprayers have already been controlled. Less than 5 % of the devices are rejected after a first control. The condition of working sprayers has been improved. At last, this action has made the controlled owner conscious of the problems related to the spreading og agrochemicals. [less ▲]

A European stream leads member countries to take action on sprayer conformity. Volontary inspection of crop sprayers are carried out in several countries. These control methods are not always specifically defined. Other countries, such as Germany, Holland and Belgium, have established a compulsory inspection of crop sprayers already in use. In these cases, inspection methods and practical organisation have been clearly and officially defined. The Belgian Federal Ministry of Agriculture implemented on 04 September 1995 a compulsory inspection of crop sprayers in use in Belgium. Prior to that, the first goal was to choose a method adapted to an “on site” inspection. The control procedure that has been selected for the whole of Belgium is different from that practiced in many countries where the patternator is used. The practical organisation on site is also quite different. [less ▲]

A successful spray application doesn't only depend on the choice of the appropriate chemical product and on the treatment period, but also depends on the user's abilities and the working order of the crop sprayer. The experience shows that these two points often pose a problem. Concerning the equipment, many countries have taken initiatives for the sprayers control. This one is usually free but the tendance is to make it obligatory. The control method implemented in Belgium (Wallon region) is different from the general method based on the use of a spray pattern collector: it is completely mobile and is essentially based on the measure of the pressure at the boom and of the nozzles output. The results show that many sprayers are not in a good working order. [less ▲]
