Level of Pollution on Surrounding Environment from Landfill Aftercare

Abstract

This work examines how the pollution from landfill aftercare effect the surrounding area and water basins. The subject of the study was a closed landfill where waste was disposed of without any accounting and operation of the landfill. During the study, soil, surface water, and sediment samples were taken over a two-year period. The data obtained compared with the maximum allowable concentrations established in the Northern part of Lithuania. The water sampling sites were selected taking into account the direction of the water flow, and the landfill was found to influence the water quality. Within 500 meters before the landfill, heavy metals and metalloid concentrations did not exceed the maximum allowable concentrations (Pb ≤ 20 µg/L; Ni ≤ 40 µg/L; Cr ≤ 100 µg/L; Cu ≤ 100 µg/L and As ≤ 20 µg/L). Soil and water sediment contamination factor and contamination level were determined for each metal and metalloid individually, which showed that as a single chemical element and its compounds none of them pose any danger to the environment. A different situation can be seen when calculating the total level of contamination, taking into account all pollutants classified as very hazardous, Z d > 10. The results showed that monitoring (of surface water, including soil) and investigations, helping to reduce negative environmental impact, should be continued in the closed landfill. mass and accumulate in the environment, everywhere: in soils, surface water and in basin sediment. The greatest danger is the possibility that a metal through the food chain can get in the human body [10]. The accumulation of heavy metal and metalloid in soil severely affects the bioaccumulation processes [11][12][13][14][15]. Local people in different areas cultivate vegetables, grazing cattle a nearby landfill maintenance and are threatened by heavy metal and metalloids exposure. This work examines how pollution from closed landfills affect the closed territories and surface water pools. The heavy metals and metalloids are the pollutants in the environment [16][17][18], which can be found in soil and water and sediments. Five heavy metals and metalloid have found near landfill, which are arsenic (As), cadmium (Cd), copper (Cu), zinc (Zn) and lead (Pb) [19][20][21][22][23]. The same chemical elements, which may pose the greatest environmental and human health hazards have been researched in this study. The main aim of the research is to identify whether there is an environmental impact on surrounding area of landfill aftercare. The research done with three segments of environment: soil, water and sediments heavy metals and metalloid accumulation measurement and analysis.

Heavy metals accumulation in Hertia cheirifolia along the highway in Setif region, Algeria

“…The high concentrations of MTE found in the uncontrolled open landfill site have several origins. The high levels of Zn, Sb, and Pb are the consequence of the presence of leachate, which contains many mineral contaminants (Baziene et al 2020). Authors made the same observations confirming that the leachate is highly polluted by MTE, with major contamination by Zn and Pb (Koné et al 2007;Mehdi et al 2007;Sangaré et al 2016).…”

Numerical simulation of heavy metal migration in stabilized soils under multi-field coupling

“…Zhang et al [11] employed the TOUGHREACT software to simulate arsenic migration in geological carbon storage formations proximal to carbon dioxide injection wells, revealing that an elevated gas injection rate enhances metal migration. Furthermore, previous studies have demonstrated that the infiltration of rainwater poses a risk of heavy metal migration in the soil, with the extent of migration being directly proportional to rainfall intensity [12,13].…”

Metagenomics Analysis Reveals the Microbial Communities, Antimicrobial Resistance Gene Diversity and Potential Pathogen Transmission Risk of Two Different Landfills in China

“…The imbalance between waste production and treatment capacity is intensifying the predicament of garbage siege. On the other hand, due to historical factors, there are many non-sanitary landfills in China, and the irregular waste disposal from these landfills has caused severe pollution threats to soil and groundwater [4,5], as well as the risk on surrounding public health [6].…”
