“…According to our previous experiment as well as Fernándèz et al (2000), Balarama Krishna et al (2003) and Gupta et al (2010) this temperature was low enough to prevent significant loss of mercury. Mercury was analysed using an AMA 254 Advanced Mercury Analyser.…”

Pleurozium schreberi as bioindicator of mercury pollution in heavily industrialized region

et al. 2013

This research is continuation of the investigation of metal accumulation in native and transplanted moss Pleurozium schreberi in the most industrialized and affected region in Poland (Upper Silesia). We tested the hypotheses that in Upper Silesia transplants of P. schreberi may be used in a 90 days bioindication experiment in case native specimens are absent; a 90 days exposure of transplanted P. schreberi was long enough for evaluation of Hg pollution of the environment. An assay was carried out with native mosses at 27 polluted sites and mosses from an uncontaminated control site transplanted to the same 27 polluted sites. P. schreberi collected from the same sites as classified for more and less polluted basing on Pb and Zn concentrations show quite different pattern of pollution with mercury; The accumulation of Hg by the transplants increased much faster in the first 45 days of the experiment (accumulation factor 1.5-6.7; mean 3.4±0.5) in comparison with the second period from day 45 to 90 (accumulation factor 1.0-1.6; mean 1.2±0.1). The 90 days exposure of transplanted P. schreberi was long enough for evaluation of Hg pollution of the J Atmos Chem (2013)

“…The group of extracts with low Zn content contained four samples of Normosan (nos. 3,6,7,9), in which the concentration of Zn was between 1.59 and 3.01 mg/kg. On the other hand, the highest content of Zn was observed in the samples of Infektoten 5.95-8.13 mg/kg, Pyrosan 5.84-11.20 mg/kg, and Urosan, except for sample no.…”

This was done assuming that a patient would drink a glass of infusion (200 mL) 3 times a day, prepared from 2 g of a herbal mixture (as recommended by manufacturers).…”

“…It is well known that heavy metals in herbal products pose a substantial health hazard due to their toxic and mutagenic effects, regardless of the concentration levels [3]. Fast industrialization, ineffective pollution control and inconsiderate use of chemical fertilizers and pest control agents largely contribute to heavy metal contamination in agricultural soils.…”

AbstractThe content of 8 heavy metals (Cd, Cr, Cu, Fe, Mn, Ni, Pb and Zn) was evaluated in infusions prepared from 13 different herbal compositions commercially available in drug or herbal stores. The mixtures were produced by a Polish manufacturer “Herbapol”. The concentration of heavy metals was determined using flame atomic absorption spectrometry (FAAS). In the herbal infusions Mn was found in the highest concentration varying from 3.03 to 129.01 mg/kg. The element of the lowest content was Cd in the range of 0.024–0.153 mg/kg. According to interquartile ranges the concentrations of studied heavy metals in infusions decreased in the following descending order: Mn>Fe>Zn>Cu>Ni>Cr>Pb>Cd. Cluster analysis allowed for the division of herbal infusions into groups described by comparable levels of heavy metals. In water extracts made from Urosan, Nervosan, Infektoten and Cholagoga, distinctive levels of Mn, Fe and Cr were determined. According to WHO regulations, the concentrations of the elements did not exceed the allowable limits.

“…It has been reported that several diseases, such as disorders of the nervous, digestive, and hematopoietic systems and even organ deformities, could be caused by heavy metal poisoning, including Pb, Cd, As, Hg, Sn, and Sb poisoning [4,5]. Therefore, with increasing industrialization and environmental pollution, it is necessary to monitor the content of some toxic heavy metal elements in various foods.…”
