Abstract

Evolution of organochlorine and organophosphorus pesticides???s residues in Akkar region in Lebanon linked to an evaluation of their toxicity using E.coli K12, Pseudomonas aeruginosa H103 and Salmonella enterica

Lebanon’s agriculture represents 2.92% of its economy [1] and it is mainly used to feed the country even if part (potato, cereals, citrus fruits, etc.) is also exported to other countries (Kuwait, Qatar, Saudi Arabia, etc.) [2]. However, intensive and unregulated use of pesticides in the agricultural regions of the Northwest of Lebanon, specifically in Akkar (second agricultural region in terms of surface area) has generated contamination of the water resources adjacent to the cultivation areas [3] [4] [5]. The inhabitants of this region use groundwater as the main source of drinking water but also for irrigation [6]. Thus, the risks associated with this deterioration in the sanitary quality of water induced researchers to try to set up programs to monitor the evolution of the levels of organic pollutants from 2014. The aim of this study was to assess the evolution of groundwater contamination by two classes of pesticides (organochlorines - OCPs, organophosphates - OPPs) in wells in Akkar plain, based on two studies carried out in 2014 and 2016 [4] [7] and on a work currently being carried out, also this study try to evaluate the toxicity of exicted pesticides in this wells using three different types of bacteria : E.coli K12, Pseudomonas aeruginosa H103 and salmonella enterica, diffrents tests has done (created) to conclude the effect of those pesticide upon these bacteria.
