The aim of this study is to evaluate time distribution of gaseous pollutants’ concentration levels, sulphur dioxide (SO₂, μg · m⁻³), nitrogen dioxide (NO₂, μg · m⁻³) and to characterise biothermal conditions, based on subjective temperature index (STI, °C) in Legnica, Lower Silesian Voivodeship. Assessment of the seasonal and daily SO₂ and NO₂ concentration and STI values in the studied period was based on descriptive statistics. The analysis of NO₂ and SO₂ concentration frequency was performed in reference to the scale applied in the interpretation of the STI. The assessment of the analysed period’s biothermal conditions did not show an occurrence of thermal sensation “boiling hot”. The most adverse aerosanitary conditions caused by high concentration of SO₂ in the air are accompanied by a sensation of “freezing”. The highest fluctuation in the content of NO₂ and SO₂ in the air was characteristic for the winter with the occurrence of “freezing” and “very cold” sensation. The highest concentration of SO₂ amounting to 234 μg ∙ m⁻³ was recorded in the winter of 2005 and highest NO₂ concentration was recorded in the spring of 2009, amounting to 184 μg ∙ m⁻³. The NO₂ and SO₂ concentration shows a reverse circadian course in comparison to the course of apparent temperature.
The aim of the article is to present the Record Sheet of Animate Natural Monuments for trees, which would standardize collecting and presenting data on tree monuments. The study uses data from the Register of Natural Monuments of the Lower Silesian Voivodeship made available by the Regional Directorate for Environmental Protection (RDOŚ) in Wrocław, as well as form the existing municipal record sheets of nature monuments and the Central Register of Forms of Nature Protection (CRFOP) facilitated by the General Directorate for Environmental Protection. Based on the qualitative assessment and the range of data contained in the RDOŚ and CRFOP registries and record sheets, an original proposal for a natural monument record sheet was elaborated for both individual trees and groups. The proposed consistent range of data on natural monuments will enable the use of collected data in statistical surveys, comparative analyses, and the research on species. In addition, the quality of data collection will contribute to a proper protection of trees and their surroundings.
