Determination of profenophosin toxicity in Caspian seals fatty tissue in the southern Caspian Sea (Marine coast of Golestan and Mazandaran province), Iran

Profenophos is one of the organophosphorus poisons. This fast-acting poison control a very wide range of rodent and sucker organisms. Due to the widespread use of this poison in the farms around the Caspian Sea, we measured the amount of bioavailability of perthenophosum in 10 corpsees of the Caspian Sea, collected from the coasts of Golestan and Mazandaran provinces. Caspian seals is the only mosquito of the Caspian Sea, which has been endangered in recent years. corpsees were transferred to the laboratory and samples were taken from the adipose tissue to measure Profenophos toxin and, after preparation, samples were injected into a Gas chromatograph(GC-MS) and the concentration of toxin was measured by the apparatus. 100% of samples were contaminated with Profenophos. The mean of poison concentration in adipose tissue was 3.68±0.73μg / kg. The highest amount of this toxin was measured in adipose tissue 6 μg / kg and the lowest amount of this 0.5 μg / kg poison was measured. Considering the high concentration of Profenophos in the tissues of the Caspian seals and also the widespread use of this poison in agriculture to cope with the problem, in order to reduce pollution of the Caspian Sea, as well as to save the remaining Caspian seals, as well as the health of others Aquaculture in the Caspian Sea, it is necessary to take measures to prevent the entry of this dangerous pollutant into the Caspian Sea.
