Summary Heavy metals are natural ingredients of many plant cultures, and they are increasingly found in the soil as the main group of inorganic contaminants. The consumption of food products, either fresh or processed, with an increased concentration of heavy metals leads to the deposition of these metals in the body, which further leads to a series of consequences in the form of cardiovascular, respiratory, and neurological problems. The behavior of heavy metals in soil and their accumulation by plants depends on many factors, such as soil structure, soil pH value, organic matter content, adsorption complex and other factors. Therefore, the aim of this work is to present the influence of physical and chemical soil parameters on the distribution of heavy metals (Pb(II) and Cd(II)) in plant cultures and to assess the health risk pollution of the mentioned metals in plant cultures (cucumber, pepper, tomato, eggplant).

: Water preparation for industrial use commonly involves a multi-stage approach to raw water treatment. The selection of individual treatment operations is based on various factors. Adherence to regulations and standards on water quality for a specific purpose is of key importance, as the entire treatment process should meet or exceed applicable regulatory standards. In the selected plant for the preparation of industrial water, an evaluation of the efficiency and economy of the process was carried out by comparing the results of water analysis before and after each treatment, by reviewing the justification of the location of the process units in the treatment line, and by analyzing the selected process parameters. The results of water analyzes confirmed that adequate selection and location of unit operations in the raw water treatment line can have multiple beneficial effects in meeting water quality requirements for the desired purpose.
