Environmental Pollution with the Heavy Metal Compound

The contamination of important synthetic (surface unmodified) polymers by various heavy metal compounds (such as copper, manganese and lead) in aqueous medium was investigated in this study. The influence of the pH of the aqueous medium, temperature and metal type on contamination was investigated during a 10 day period. It was found that increasing pH contributed to higher polymer contamination (at higher pH 100 times for copper and up to 400 times for lead), as well as contact with easily penetrable substances. Increasing temperature decreased contamination by the metal compound for PELD and PET which was not the case for PEHD and PR.

The article deals with a number of topical issues connected with transport geoconstruction and environmental pollution such as heavy metal ion pollutions of soils. The main aim of the study is to present new problem solutions and technologies for geoconstruction concerning pure substance use for lithosphere. Silica sol solution was chosen as this substance. The choice was made because of silica sol nature. Having important properties, it is the purest substance for the environment. Experimental methods were carried out. The study introduces new technologies of silica sol solution use in geoconstruction systems: silica sol detoxication technology (SDT) for soils, silica sol absorption technology (SAT), soil strengthening technology (SST), silica sol blocking action technology (SBT). The article shows the examples of these technologies’ application and examines new main properties of geoconstruction systems.
