, the sufficient data was collected and then categorized regarding the applications and the total amount of used
pesticides in a year. The results demonstrated that there were
60 sorts of used pesticides in Iran. They included Or-
(10%), Organophosphorus (28.4%), Pyrethroids derivatives (10%), Carbamate derivatives (10%), and
(41.6%). The commonest pesticide used in a year was Organophosphorus and the least one was Organochlorine.
The obtained data pointed out that the most common pesticide was Organophosphorus. Given that Organophosphorine
compounds are poisonous in living creatures and cause short and long term side effects. It is recommended that re-
sponsible authorities provide the necessary information for the aimed groups in terms of the allowable using amount of
pesticides, the protection strategies and the pesticides hazards on users.

pesticides are used in agriculture sector in the world. 50% of them penetrate to soil, water and other sources The increasing population necessitates more agricultural and also to the bodies of living creatures [7]. Relevant products and foodstuffs that consequently need more poisoning in many countries, especially in developing pesticide usage to destroy any pests [1,2].
