The Impact

The issue of improving the algorithm for calculating and distributing payments for environmental pollution by polycyclic aromatic hydrocarbons (PAHs) of technogenic origin (from both stationary and mobile sources) is considered. It is proposed to use an indicative method (index of the total toxic effect of biologically available PAHs) to take into account the negative impact on the biosphere of all 16 priority PAHs and for a more objective and differentiated distribution of the amount of payments between the owners of pollution sources.

Polycyclic Aromatic

The contamination level of sea bottom sediments with polycyclic aromatic hydrocarbons in the Balaklava Bay (the Black Sea) was estimated depending on sediments particle size distribution. The total content of these pollutants in the studied water area was averagely 2459,58 ng/g. The increased concentrations of polycyclic aromatic hydrocarbons are confined to the eastern coast and the central part of the bay. Fourteen polyaromatic hydrocarbons were totally identified in 2018, four of which (naphthalene, 2-methylnaphthalene, fluorene, anthracene) had a trace content. Four- and fivecyclic aromatic hydrocarbons made the main contribution to the pollution of sea bottom sediments. In particular, it was chrysene (40,1 %), fluoranthene (17,5 %), benz(b)fluoranthene (15,1 %). The concentration of benz(a)pyrene in bottom sediments of the Balaklava bay ranged from 0,05 - 121,0 ng/g. Its increased concentrations are confined to the central part of the bay in the eastern coast. The amount of polyarenes correlated with the part of silt fraction (0,05 - 0,1 mm)...

We show that polycyclic aromatic hydrocarbon (PAH) chromophores that are linked between two five-membered rings can access planarized structures with reduced optical gaps and redox potentials. Two aceanthrylene chromophores were connected into dimer model systems with the chromophores either projected outward (2,2’-biaceanthrylene) or inward (1,1’-biaceanthrylene) and the optical and electronic properties were compared. Only the planar 2,2’-biaceanthrylene system showed significant reductions of the optical gaps (1 eV) and redox potentials in relation to the aceanthrylene monomer.<br>
