The research included, for a period of 6 months, a study of two aspects. The first was the isolation and diagnosis of oomycetes in the water of Al-Diwaniyah River in five sites. The sites where pollution increased were chosen, namely textile, rubber factories, and sites before water treatment, compared to two sites: Sadr Al-Daghara and a site under Al-Diwaniyah Bridge, which had little pollution, as the percentage of pollution increased. Ovomycetes in pollution sites in order to increase the organic matter in them and to provide many nutrients, knowing that these fungi were isolated from control areas, but in small proportions, in addition to other groups of non-oomycetes and the previously dominant types of Oomycetes. Some physical tests were conducted on the water of the Diwaniyah River in the study sites to observe the suitability of the physical characteristics for the presence of these fungi, namely temperature, PH, alkalinity, hardness, and others. The second aspect is to consider these fungi as indicators of pollution in the river water when they are present in polluted areas by analyzing the enzymatic filtrate to measure The percentages of presence of heavy metals, such as cadmium, mercury, lead, and selenium, which appeared in high percentages that exceeded the permissible limits for their presence, whether in river water or in the bodies of living organisms. The percentages of cadmium were (0.012)% in Saprolegnia sp. and Pythium sp., while the percentages of lead were (1.5, 1.3).)% in Saprolegnia sp and Fusarium sp, while mercury recorded a percentage of (0.3, 0.05, 1.2)% in Achlya., Apodachlya sp.,. Fusarium sp. Selenium appeared at a rate of (0.2)% in Apodachlya sp, Arsenic in Pythium sp. At a rate of (0.02%) also for the purpose of comparison of these results, tests were conducted for heavy metals in the water at the selected sites (L3, L2, L1) (fabric, rubber, and site before treatment) respectively. The results showed the appearance of heavy metals (cadmium, lead, mercury, arsenic, selenium). In high percentages compared to sites L4 and L5, their percentages were very small, almost reaching zero.

Light pollution is one of the types of environmental pollution. The sky illuminated by the excessive light emission is an inherent element of the modern world. This phenomenon has been known for over a century, but research has been carried out only for several decades. Analysis of the brightness of the sky was made for Toruń (Poland) and neighboring areas. The main aim of the study was to study the distribution of brightness of the sky over a medium-sized city. The basic research method was a direct measurement of brightness made with the SQM photometer. The conducted research was carried out throughout the calendar year on 24 measurement stations located in Toruń. Measurement stations represented various types of buildings occurring in every city. On the basis of the obtained data, a map was made showing the extent of light pollution and its intensity, as well as the spatial distribution of this phenomenon. The brightness of the sky was also examined in terms of astronomical and weather conditions. Each aspect is documented in tabular and visual form.

Research on these forms of pollution has been continued for many years and the awareness of their prevalence and effects among average citizens is growing.…”

The paper presents results of research on light pollution in the night sky of Toruń. A permanent network of measuring stations has been established in the city, consisting of 24 sites representing various types of land development and land cover: single-family housing, city centre, multi-family housing, areas overgrown with vegetation and open areas. Within this network, a repeatable direct measurement of the sky brightness using an SQM photometer was carried out over a period of three consecutive months in the summer season, i.e. from June to September 2017. The measurement sessions were conducted in similar weather and astronomical conditions. Based on the obtained data, a spatial distribution of light pollution was determined, ranges of values obtained during the measurements were provided, and the results were additionally referred to the distinguished land cover categories and land development types.
