Action plan for old pesticides POPs : The pesticides POPs are nine including DDT , cyclodienes family and lindane .
Old pesticides POPs : since these pollutants are non polar compounds they do have the following disadvanteges : 1.They acummulate the fat tissues in human body throw the food chain, causing carcinoginic effects and dmaging some internal organs . 2.They are persistant, leading to acummulate in the enviromental components for more than fifty years ,particularly in the soil.
Activity : They were useful for controlling some agricultural pests and public health insect pests. Lead Agency : Ministry of Agriculture
Stakeholders: Ministry of Environment , Ministry of Agriculture, Ministry of Health Budget : All stored old pesticides POPs have been destroyed abroad by a French company in 2014 , but we need estimated budget to achieve the following : A.100,000 JDs to follow up their occurrence in Jordan , to make awareness and to conduct studies . B.150,000 JDs to monitor the residues of pesticide POPs in the different components of the environment ,since we still find some of the pesticides POPs as residues in human mothers milk , animal products ,soil and agriculture crops up to now.
Time limit : Up to the coming five years
Action plan for new pesticides POPs: The pesticides POPs are six including endusulfan , chlordecone and BHC family
New pesticides POPs : since these pollutants are non polar compounds they do have the following disadvanteges : 1.They acummulate the fat tissues in human body throw the food chain, causing carcinoginic effects and dmaging some internal organs . 2.They are persistant, leading to acummulate in the enviromental components for more than fifty years ,particularly in the soil.
Activity : some of them were useful for controlling some agricultural pests ,animal health insect pests and industrial chemical by product . Lead Agency : Ministry of Agriculture
Stakeholders: Ministry of Environment , Ministry of Agriculture, Ministry of Health Budget : some of the new pesticides POPs have not been introduce to Jordan such as chlordecone .others have been used to control agricultural pests such as endusulfan or being produced as industrial chemical by product such as some isomers of BHC .The estimated budget is needed to achieve the following : 50,000 JDs to follow up their occurrence in Jordan , to make awareness and to conduct studies . 100,000 JDs to monitor the residues of pesticide POPs in the different components of the environment ,since we still find some of the pesticides POPs as residues in human mothers milk , animal products ,soil and agriculture crops up to now.
Time limit : Up to the coming five years.
