چکیده مقاله:
In recent decades, Developments in industrial and agricultural sectors and the promotion ofhuman life have made the use of heavy metals unavoidable in different fields. Organic andinorganic pollutants, such as heavy metals, after entering the ecosystem accumulate in the bodyof aquatic organisms and through biological cycles are transported to higher food levels andeventually to humans. Heavy metals are particularly important because of the toxic effects andbioavailability of various aquatic species and entering into food chains. The presence of heavymetals in the environment, more than the defined standards, causes environmental problems forthe habitants of the place and the ecosystem.In this study, for determination of the amount of lead accumulation in the oral tissues of thevannamei shrimp of the family Penaeidae in the cultivated fields of Bushehr, ۷۰ shrimpsamples were collected during four stages of hunting in the months of July, August, Septemberand October, for two consecutive years. The measurement of lead was done using atomicabsorption device.The results showed that the concentration of lead in the edible tissue of these shrimps wasbetween ۰ and ۱.۵۵ mg / kg wet weight while the standard concentration for lead is ۰.۵ mg / kgwet weight. Generally, the concentration of lead in the edible tissues of the sampled shrimpswas much higher than the WHO standard concentration.
