“…Therefore, in this study, given the statistically significant difference in the average incidence of empty pollen grains between area C and the other two areas, as well as the absence of a statistically significant difference between area A and area B, there is first evidence that local pollution might be the reason why the studied species show increased pollen abortivity when collected in the polluted areas. Our data are in agreement with evidence of the relationships between pollen viability and morphology in air pollution conditions [110][111][112].…”

Pollen and Flora as Bioindicators in Assessing the Status of Polluted Sites: The Case Study of the Mantua Lakes (SIN “Laghi di Mantova e Polo Chimico”; N Italy)

An integrated floristic and palynological approach was carried out at the site of national interest “Laghi di Mantova e Polo Chimico” to obtain an environmental assessment useful for monitoring polluted sites. The flora of highly contaminated sectors (area A and area B) was surveyed, and the floristic composition and ecological strategies of the species were compared with a control sector (area C). A total of 195 species were observed in the three sectors. Pollen preservation of six selected species was checked as a bioindicator of environmental health in the same sectors. Area A and area B likely share similar environmental pressures, including anthropogenic stressors such as pollution, geographical proximity and a similar set of habitats, leading to similarities in flora composition. Similarly, the incidence of pollen without cytoplasm is higher in area A (9.3%) and area B (7.6%) than in area C (2.5%). The floristic differences among the sectors and the quantity of empty or abnormal pollen, together with the CSR strategies adopted by the species, suggest that the effects of anthropogenic impact on local vegetation can be detected at both macroscopic and microscopic levels. The discovery of the protected species Narcissus pseudonarcissus in area C is noteworthy, which may be important in directing efforts towards the protection of plant communities in this sector.

Taraxacum officinale Wigg and the results of scientific research on the development of modern methods of physicochemical analysis of heavy metals that can be found in raw materials of Taraxacum kok-saghyz Rodin, and the presence of pesticides in plants using the GOST (governmental standard) European Pharmacopoeia standard. Methods for the quantitative determination of inductively coupled plasma mass spectrometry (ICP-MS) of heavy metals; macro and microelements in plant raw materials have been developed. The test for the presence of pesticides and heavy metals in plants according to the GOST standard of the European Pharmacopoeia was carried out in accordance with the Sanitary Rules and Standards of the Republic of Uzbekistan.

Bioindication of the environment is one of the actively developing directions of ecology. Information about pollutants and the level of environmental pollution can be obtained as a result of studying the biological reaction of plants to pollution. Ecological palynology is a new direction, when pollen of various woody and herbaceous species is used for bioindication of the level of environmental pollution and the presence of mutagens. The review considers the morphological variability of pollen, its fertility and viability under the influence of pollutants, the possibility of its use as a bioindicator of pollution of urban areas by emissions of vehicle transport and industry.
