Opis:: Generated wastes require space and financial outlays on their proper storage and processing, whereas the lack of means usually leads to depositing wastes in places not meant for this purpose. Illegal dumping sites still emerge, despite introducing in Poland the obligatory (common) fee for collection and management of wastes and the obligatory establishing the Selective Waste Collection Points in each district. The aim of the work was conducting a detailed inventory of illegal dumping sites in the area of Olsztyn district (situated in the Silesia province, on the Krakow-Częstochowa Upland) and indicting the morphological composition of the wastes deposited in these places. The paper presents a detailed analysis of the morphological composition of illegal landfill sites situated in the analyzed district. The investigations located 28 illegal dumping sites, despite the fact that a Selective Municipal Waste Collection Point operates in the district area. The analysis of location, area, mass and composition of the wastes was conducted for each illegal landfill, according to the methodology developed for this purpose. Over a half of the illegal dumping sites was situated in the forest and on 4 of them the estimated mass of dumped waste exceeded 1Mg. Debris constitutes the highest proportion (21.8%) of the waste morphological composition. Recyclable wastes, i.e. glass, plastics, paper and cardboard, used electronic and electric equipment dominated in the morphological composition of wastes on small landfills, situated close to buildings (less than 250m) and had the smallest area (below 1m2 ). The share of debris and construction wastes was growing with increasing landfill area.

Opis:: Dumping sites or landfills are considered as foremost common option of waste management worldwide. Dumping sites, often not lined, represent a potential environmental issue causing a long-term risk to the environment and health. A number of computers model-based studies have described the solid waste collection and its management, but provide little information about the relative contributions regarding environmental impacts of landfilling especially in the context of developing world. The aim of study was to estimate environmental impacts from dumping site by using EASEWASTE model. A case study was carried out at an old and closed dumping site filled with mixed waste without bottom liner, no leachate collection and gas collection. On the basis of the existing dumping site investigation, a Mahmood Booti Dumping Site Scenario was developed, and related data of waste generation & composition was collected and added to assess environmental impacts. The results show that human toxicity via soil (9.14E+09 m3 soil) had the highest potential impact, followed by global warming (8.83E+11 Kg CO2-eq), eco-toxicity in water (6.25E+11 m3 water), and eco-toxicity in soil (6.54E+10 m3 soil). This is mostly caused by leaching of heavy metals from ashes (e.g. residues from roads cleaning and vacuum cleaning bags), batteries, paper and metals. The adopted risk analysis approach uses easily accessible computer aided models, for open dumping sites, appears to be a key tool to assist decision makers in establishing priorities for remediation action.

Opis:: The paper presents an impact of the metallurgical wastes dumping site on the following parts of the environment: air, soil and surface waters. Some of the methods used to prevent wastes interactions were showed. The results of the metallurgical wastes leachate samples research, in which toxic metal ions have been found, are presented results of examinations performed on water extracts derived from two types of metallurgical wastes were given. The chemical analysis of water extracts indicate exceeded concentration of toxic metals, such as: lead, arsenic, barium and others. Preliminary results of some metals elimination from the water extracts with PUROLITE ion-exchangers were also presented. The utilised acidous cationit with Na+ groups exchanges the Ba2+ ions in almost 90%, similar to S 930 ionit with chelating groups (Table 5 and 7). Whereas the anionit with hydroxyl groups removes the arsenic ions(V) from the solution with the 60% efficacy (Table 7).
W pracy omówiono wpływ składowiska odpadów metalurgicznych na sfery środowiska: powietrze atmosferyczne, glebę i wody powierzchniowe. Przedstawiono niektóre sposoby zapobiegania oddziaływania tych odpadów. Podano wyniki badań wyciągów wodnych próbek odpadów metalurgicznych, w których stwierdzono obecność jonów metali toksycznych dla środowiska. Analizy chemiczne wodnych wyciągów wskazują na przekroczenia zawartości metali toksycznych, m.in. takich jak: ołów, arsen, bar i in. Przedstawiono również wstępne wyniki eliminacji zawartości niektórych metali z wyciągów wodnych za pomocą jonitów Firmy PUROLITE. Zastosowany silnie kwaśny kationit z grupami Na+ wykazuje zdolność wymiany jonów Ba2+ prawie w 90%, podobnie jak jonit z grupami chelatującymi S 930 (tab. 5 i 7). Natomiast anionit z grupami hydroksylowymi usuwa z roztworów jony arsenu(V) z wydajnością około 60% (tab. 7).

Opis:: Environmental risk assessment is one of the key tools in environmental engineering. This risk assessment can be qualitative or quantitative and it is based on preliminary studies i.e., baseline study for waste disposal sites. Even though the literature exists on baseline study in general, still there is a lack of guidance regarding development of a site-specific baseline study model for a waste disposal site. This study has two-fold aim, firstly, how to develop site-specific baseline study model for a selected dumping site, and secondly, how this site-specific baseline study can support the environmental engineering via mathematical risk estimation. Mahmood Booti Open Dumping Site (MBODS) is selected to demonstrate the development and application of site-specific baseline study model. This is followed by building a framework that shows how the output of the baseline study can lead to environmental engineering via mathematical risk estimation. The paper provides a mechanism of how to construct a bespoke baseline-study model that is readily useable, avoiding procurement of expensive computer software and yet smoothly connecting with the follow-on stages of the risk assessment. The work presented in this paper can be reproduced repeatedly to create site-specific baseline study models for risk assessment of other waste disposal sites in a cost-effective, consistent and cohesive manner.
