Polybrominated Diphenyl Ethers in Human Milk of Croatian First-Time Mothers: 2010 Versus 2020.

The presence of selected polybrominated diphenyl ethers (BDE-28, -47, -99, -100, -153, -154, and -183) was investigated in human milk samples collected from first-time mothers living in Zagreb, capital of Croatia. Samples from 2020 and 2010 were analyzed, and the first temporal comparison between the profiles and levels of these compounds in this area was obtained. A statistically significant difference between mass fractions depending on the sampling year was observed only for BDE-99, with values in 2020 higher than in 2010.

Sources, Ionic Composition and Acidic Properties of Bulk and Wet Atmospheric Deposition in the Eastern Middle Adriatic Region.

Atmospheric bulk and wet deposition samples were collected simultaneously at the background coastal site in the Eastern Middle Adriatic region in order to assess the impact of major ions (Cl, NO, SO, Na, K, NH, Mg, Ca) on deposition acidity and distinguish the main sources. Higher ion levels were observed during the cold period, especially for Cl, Na, Mg and K. Dust intrusion caused significant increases in levels of Ca, Mg and K, while open-fire events increased the levels of K.

Carcinogenic Activity and Risk Assessment of PAHs in Ambient Air: PM Particle Fraction and Bulk Deposition.

This paper present seasonal variation in the equivalent concentration (BaP) of PAHs in order to assess the potential cancer risk for two different groups of residents via ingestion, dermal contact and inhalation pathways. The possible ecological risk caused by PAH atmospheric deposition based on risk quotient was also estimated. A bulk (total, wet and dry) deposition and PM particle fraction (particles with an equivalent aerodynamic diameter < 10 µm) were collected from June 2020 to May 2021 at an urban residential location in the northern part of Zagreb, Croatia.
