Article Synopsis
- * Most persistent organic pollutants (POPs) showed declining trends, except for hexachlorobenzene (HCB), which either increased or remained stable across the stations.
- * Chemicals of Emerging Arctic Concern (CEAC) showed stable or increasing trends, highlighting the need for continued monitoring and consistent data to assess the effectiveness of chemical regulations.
Article Synopsis
- Two decades of atmospheric measurements of polycyclic aromatic hydrocarbons (PAHs) were carried out in the Arctic, revealing a decrease in PAH concentrations with higher latitudes, with Pallas having the highest levels.
- Forest fires were found to be a major source of PAHs, but the expected long-term decline in PAH levels was not observed despite reductions in emissions.
- A 3-D global transport model indicated that warming in the Arctic could lead to increased concentrations of certain PAHs (PHE and PYR) due to higher volatilization, while less impact was seen on particle-bound PAH (BaP), highlighting potential effects on other airborne pollutants.
The large surface area of Lake Victoria (about 68,800 km) makes it vulnerable to high atmospheric deposition of chemical pollutants. We present measurements of polychlorinated biphenyls (PCBs) from the lake's atmospheric environment. High volume air (24 h) samples were collected within the northern Lake Victoria watershed in Uganda over two periods; 1999-2004 [at Kakira (KAK) and Entebbe (EBB)] and 2008-2010 (at EBB only).

Four OPEs were detected in up to 97% of the samples, seven in 50% or less of the samples, and three were not detected. Median concentrations of ∑OPEs were 237 and 50 pg m(-3) for ship- and land-based samples, respectively.
