Application of the moss bag biomonitoring technique in an active volcanic environment (Mt. Etna, Italy).
2011
This paper presents the preliminary results of a biomonitoring study based on the use of moss bags exposed at 24 sites on Etna volcano. Sphagnum mosses were used to study bioaccumulation originating from atmospheric deposition, by measuring the tissue contents of major and a large suite of trace elements. Elements, such as Tl, Bi, As, Se, Cu and Cd, display high concentrations in the exposed samples close to the active vents. This study confirms the effectiveness of the moss bags technique also in active volcanic areas.

The results of a biomonitoring surveys carried on in Palermo using the accumulation of heavy metals in lichens, thalli of Xanthoria s.l. as indicators of air pollution are reported in this work. Beginning from the data of 38 simple sites shed on Palermo’s territory, has been developed a study of the air pollution in the centre of the town, the target of this work is to know the existing relationship between the concentration of heavy metals study area and the possible pollution sources as industry, shipyards, vehicles etc. In order to recuperate most information of the territory, the development of this work has been carried on with a new technology for the data management: the GIS (Geograp…

Health Risk Assessment of Exposure to 15 Essential and Toxic Elements in Spanish Women of Reproductive Age: A Case Study
2021
This case study investigates the exposure of 119 Spanish women of reproductive age to 5 essential (Co, Cu, Mn, V, Zn) and 10 toxic (Ba, Be, Cs, Ni, Pb, Pt, Sb, Th, Al, U) elements and assesses their risk. The essential elements (Co, Cu, Mn, V, and Zn) showed average concentrations (GM: geometric mean) of 0.8, 35, 0.5, 0.2, and 347 μg/L, respectively. Five of the toxic elements (Ba, Cs, Ni, Al, U) exhibited detection frequencies of 100%. The GM concentrations of the novel toxic elements were 12 μg/L (Al), 0.01 μg/L (Pt), 0.02 μg/L (U), 0.12 μg/L (Th), 0.009 μg/L (Be) and 4 μg/L (Cs). The urine analysis was combined with a survey to assess any variations between subgroups…
Augsnes un veģetācijas izmaiņas piesārņojuma dēļ Rīgas pilsētas mežos
2017
Pilsētas vides piesārņojumu var novērtēt dažādos veidos un viens no visbiežāk izmantotajiem ir sūnu biomonitorings. Līdz šim vēl nav atklāti un noskaidroti vienoti standarti par sūnu biomonitoringa efektīvāku izmantošanu. Nav arī vienota pētījuma par augsnes piesārņojuma ietekmi uz augu sugu daudzveidību. Pētījuma mērķis ir noskaidrot pilsētas vides piesārņotības pakāpes izvērtējumu, izmantojot sūnas un augsni kā bioindikatorus, un noteikt augu sugu daudzveidību atkarībā no augsnes piesārņojuma. Sphagnum sūnu sastāvā esošās smago metālu augstās koncentrācijas norāda, ka lielākais vides piesārņojums atrodams ceļa malās ar intensīvu satiksmi vai rūpnīcu, ostu tuvumā. Smago metālu piesārņojums…
Badania nad potencjalnym wykorzystaniem pluskwiaków różnoskrzydłych (Hemiptera: Heteroptera) w bioindykacji i monitoringu przyrodniczym
2023
This paper presented the results of the studies on true bugs (Hemiptera: Heteroptera) alongside evaluating their potential usefulness in biomonitoring and bioindication. The studies were carried out in May and August of 2017. Three research sites situated at various distances from the full-scale plants (Grupa Azoty Zakłady Azotowe Kędzierzyn SA, Zakłady Chemiczne Petrochemia-Blachownia SA, Zakłady Koksownicze ArcelorMittal Poland Zdzieszowice) and the control area out of reach of the emission of chemical pollutants, i.e. the meadows in the Chrząstowice area of Natura 2000, have been selected for studies. All studied meadows were classified within the Molinio-Arrhenatheretea class. As a resu…

Mushrooms as biomonitors of heavy metals contamination in forest areas
2018
The aim of the research was to assess the level of contamination with heavy metals (manganese, iron, nickel, copper, zinc, cadmium and lead) in two forest areas selected in different places in Poland: the first one in the Swietokrzyskie Province (forests of the Staporkow Forest Division) and the second one in the Opolskie Province (forests of the Kup Forest Division). The degree of contamination of these forest areas with analytes was found using edible large-fruited mushrooms naturally occurring there - the research was carried out using passive biomonitoring method. Heavy metals in mushrooms (separately in stems and hats) as well as in soil samples were determined by atomic absorption spe…
Exposure assessment of mycotoxins in food and biological samples through high resolution mass spectrometry-based strategies
2022
Las micotoxinas son metabolitos secundarios tóxicos producidos por varios géneros de hongos y que se encuentran frecuentemente en productos alimenticios. La ingestión de micotoxinas puede provocar la aparición de un amplio abanico de efectos perjudiciales para la salud. Con el objetivo de reducir el impacto sanitario debido a la ingesta de productos contaminados por micotoxinas, la Comisión Europea estableció la Regulación No 1881/2006, donde se fijan límites máximos para ciertas micotoxinas en varias tipologías de productos alimenticios. Como herramienta complementaria, el Panel de Contaminantes en la Cadena Alimentaria (CONTAM Panel) han propuesto valores de ingesta diaria tolerable, que …
