- •
The POP levels were generally higher in the south, closer to the original source areas, compared to the north.
- •
Elevated concentration levels of low-chlorinated PCBs, chlordanes and α-HCH were detected in the north.
- •
Most of the legacy POPs showed statistically significant decreasing trends varying from 2 to 6% per year.
- •
The projections suggest that the most long-lived compounds will persist in the atmospheric cycle beyond 2030.
