Özet:

 

Among the chemicals most commonly used currently in our environment, Those are undoubtedly pesticides and related products. If pesticides are at first appeared beneficial, harmful side effects have been gradually revealed. Their toxicity, due to the molecular structure is not limited indeed to only species that we wish to eliminate. They are particularly toxic to the various components of the environment. Our study aims to assess the degree of pollution of soil and surface water in farming areas situated in the North-Est of Algeria and subject to the effect of pesticides for several years. To do this, the physico - chemical characteristics of water and soil were determined. The analyzes have focused on pH, BOD5,COD, electrical conductivity, organic matter, nitrites and nitrates. The total microflora samples of water and soil was also evaluated. The physicochemical parameters studied were analyzed by standard methods according to the general guidelines for storage and manipulation. The fungal microflora was determined using identification keys. The identification of isolated and purified bacteria was instead performed by a scan apiweb software (Api web Biomerieux France). The results show that there is a pollution of water and soil. The values of some parameters often exceed the prescribed standards and especially those of nitrite and electrical conductivity. The isolated microflora consists of 97% whose most frequent are Bacillus and Micrococcus and 3% of fungi with a predominance of Aspergillus.
