Effect of wind speed on the level of particulate matter PM10 concentration in atmospheric air during winter season in vicinity of Large Combustion Plant
Journal of Atmospheric Chemistry, 2020Co-Authors: Robert Cichowicz, Grzegorz Wielgosiński, Wojciech FetterAbstract:The concentrations of suspended particulate matter PM10 in two-month winter period, i.e. December–January in years 2009–2015, were analyzed in relation to the values of wind speed in that time. It was possible to analyze results of air pollution measurements performed in the measuring station from the perspective of their higher levels in winter seasons (so-called smog episodes). Results from 3 stations of the Regional Inspectorate for Environmental Protection in Poznań (WIOŚ Poznań) served for better presentation of smog episodes in the region (black smog) and aimed at verification of correctness of the measurements of pollution immission in the monitoring station in Piotrkowice which is situated in vicinity of Large Combustion Plant. The analysis confirmed that with low speeds of wind higher values of particulate matter PM10 were observed. The results of the analysis also show the displacement of pollutants according to the current wind direction or their local persistence for a longer time over one area.

A survey of the threat of surface water acidification to the nature conservation interest of fresh waters on Sites of Special Scientific Interest in Britain
Aquatic Conservation: Marine and Freshwater Ecosystems, 1994Co-Authors: Carrie A. Rimes, Andrew M. Farmer, David HowellAbstract:This study collated information relating to acidification of running and standing waters on Sites of Special Scientific Interest (SSSIs) throughout Britain in acid-sensitive areas. Of those SSSIs which occur in acid-sensitive areas of Britain, 196 have water bodies. The following information was obtained for each site if available: details of local geology and soils, types of land use and management, water quality data and data relating to biological components of both the aquatic and riparian habitats. In addition, samples from 112 water bodies were collected for water chemistry and epilithic diatom analysis. Results from each site were placed into existing critical loads and species response models to determine whether acidification had occurred. Results showed that the fresh waters on 141 SSSIs had probably suffered acidification. This was most acute in north Wales, with mid Wales, south-west and north-east Scotland and northern England also being badly affected. A wide variety of changes in the biological status of water bodies relating to acidification were found to have been recorded on SSSIs, ranging from phytoplankton, invertebrate and macrophyte community changes to decline of fish, amphibian, bird and mammal populations. Catchment afforestation may be a problem in poorly buffered areas and has probably contributed to freshwater acidification on 40 SSSIs. Comparison with critical loads maps for acidity in UK fresh waters reveals that existing commitments on acidifying emissions (the EC Large Combustion Plant Directive) will not be sufficient to prevent further acidification on a number of SSSIs. In order to achieve a protection of the nature conservation interest of fresh waters further commitments to emission reductions will be necessary.
