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…

Aplicación de la cromatografía líquida acoplada a la espectrometría de masas para la evaluación de la exposición interna a contaminantes alimentarios
2020
La contaminación química es actualmente un grave problema de salud pública. La producción de sustancias químicas aumenta a un ritmo vertiginoso, y aunque los países desarrollados (OECD) producen la mayoría de las mismas, el crecimiento en países como Brasil, India, Indonesia, China o Sudáfrica (BRIICS) se produce con mayor velocidad. Un porcentaje elevado de estas sustancias son potencialmente peligrosas para la salud, y el ser humano está expuesto a las mismas principalmente mediante ingestión, inhalación o por vía dérmica. Consecuentemente, es importante para la protección de la salud estudiar el grado de exposición de la población a las distintas sustancias químicas, ya sea mediante la m…

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…
