    The aim of this study was to investigate the behaviour trends of the harmful to human health persistent organic pollutants in the Rila Mountains' atmosphere. Passive air monitoring was carried out at Basic Ecological Observatory - Moussala, Bulgaria, during the period of three years. PAHs - naphthalene (1482.99 ng sample-1), biphenyl (533.14 ng sample-1), phenantrene (384.10 ng sample-1) and fluorene (293.04 ng sample-1) have highest concentrations, followed by organochlorine pesticides (DDTs, HCHs) and PCBs. A mathematical model of the data set was made using an artificial neural network. Clear positive correlation in PCB 118, PCB 138, PCB 180 and o,p'-DDT, d-HCH, PER, p,p'-DDT, p,p'-DDD as well as HCB behavior was observed. The variation in atmospheric load with POPs during identical time periods of two consecutive years could be attributed to significant differences in advection during the both selected time intervals.
