The seasonal changes in the concentration of polycyclic aromatic hydrocarbons in precipitation and aerosol near Lake Balaton, Hungary

Interspecies comparison of selected pollution biomarkers in dreissenid spp. inhabiting pristine and moderately polluted sites

“…This fact was demonstrated by the trace metal datasets repeatedly recorded over time in this area, which always fell within the regional geochemical background (Hlavay and Polyák, 2002;Nguyen et al, 2005;Ács et al, 2015). Similarly for PAHs, their concentration in the sediment was always very low and did not significantly differ from the values characteristic for open areas of the lake (Kiss et al, 1997;Kiss et al, 2001;Bodnár et al, 2005;Ács et al, 2015). Secondly, we considered the basic knowledge that contamination by metals and polycyclic hydrocarbons in aquatic organisms above certain level may: a. exceed the antioxidant capacity of the defence system; b. decrease the function of key antioxidant proteins and enzymes.…”

“…The incidence of interspecies variability in biomarker baseline levels, and the potential for their differential modulation under pollution pressure in D. bugensis and D. polymorpha was assessed at sites of Lake Balaton owing its well-known environmental characteristics as well as its low-to-moderate pollution state. Pollution surveys performed over decades have outlined an overall low contamination of the lake, with low spatial variability and insignificant seasonal pattern (Kiss et al, 1997;Kiss et al, 2001;Hlavay and Polyák, 2002;Bodnár et al, 2005;Nguyen et al, 2005). The pollution of harbour areas was evidenced only by significantly higher contaminant burdens in bottom sediments compared to open areas Kiss et al, 2001;Nguyen et al, 2005;Bodnár et al, 2005;Ács et al, 2015).…”

Within harbours, significant variability in the contamination of the sediment compartment was never recorded, which results from the fact that these harbours are characterized by very similar usage.…”

Seasonal Deposition Fluxes of Polycyclic Aromatic Hydrocarbons (PAHs) in Lake Biwa, Japan

“…PAHs concentration associated with aerosol particles are generally high in winter and low in summer (Kaupp and McLachlan, 1999;Kiss et al, 2001;Tamamura et al, 2007;Tang et al, 2005). Such trend was not observed for the deposition fluxes of PAHs in the lake especially for volatile PAHs (3 rings).…”

Modelling benzo[a]pyrene in air and vegetation for different land uses and assessment of increased health risk in the Iberian Peninsula

“…Polycyclic aromatic hydrocarbons (PAHs) can be found in the atmosphere associated with the gaseous or the particulate phases (Kiss et al 2001;Lammel et al 2009), and also in other environmental matrices such as soil, water, sediment or vegetation (Wild and Jones 1995;Chen et al 2004;Ratola et al 2010a;2010b). These chemicals raise concern among the scientific community and have been widely studied due to their carcinogenic and mutagenic properties.…”
