In recent years, several global issues related to food waste, increasing CO2 emissions, water pollution, over-fertilization, deforestation, loss of arable land, food security, and energy storage have emerged. Climate change urgently needs to be addressed from an ecological and social perspective. Implementing new indoor urban vertical farming (IUVF) operations is one way to combat the above-mentioned issues as well as foodborne illnesses, scarcity of drinking water, and more crop failure due to infection from plant pathogens and insect pests. A promising production mode is plant factories (PFs), which are indoor plant production systems completely isolated from outside environment. This paper mainly focuses on the comprehensive review of scientific papers in order to analyse the different applications of urban farming (UF) based on three different dimensions: a) the manufacturing techniques and equipment used; b) the energy that these systems require, the distribution of energy, and ways to minimize the energy-related cost; and c) the technological innovations applied in order to optimize the cultivation possibilities of IUVF.

Functioning of polymetallic factories are considerable harming the ecological systems in the environment. Operation of RMG Gold and Copper Mine in the SE part of Georgia causes severe ecological problems in the region. It is vital that conducted monitoring near the areas where industrial activities are underway. The study is aimed at eco-monitoring of the Bolnisi municipality, Georgia. The monitoring was conducted of heavy metals (Cu, Zn, Cd) in system “water-soil-plant” in the area of Kazreti (Madneuli) – villages: Balichi, Ratevani, Naxiduri, Xidiskhuri. According to the results obtained in the soil, content of heavy metals are significantly higher than the allowable concentration limit. In spite of this in crops of the plants which were grown on this soil, content of Cu and Zn does not exceed the allowed concentration limits, Cd content was not found. Study plants were green been, mauhroom, green walnut, green pepper, cucumber, cherry, potato, tomato, walnut, garlic, dry been and corn. Study water were rivers Kazretula and Mashavera's water. Rivers Kazretula and Mashavera water content Zn and Cd concentration.

Environmental pollution by heavy metals resulting from rapid economic development is a major concern. Soil, water, wheat, and rice samples were collected from the Lihe River Watershed in the Taihu Region (east China). In this study area, many types of industrial plants, including ceramics factories, plants working with refractory materials, and chemical plants are densely distributed and cause serious heavy metal pollution. In addition, well-developed transportation and agricultural activities are also important sources of heavy metals. Thus, the concentrations of selected heavy metals including cadmium (Cd), chromium (Cr), copper (Cu), nickel (Ni), lead (Pb), and zinc (Zn) in the samples were analyzed to evaluate their potential integral risk (IR) to the health of the local population. Accordingly, the spatial distribution pattern of the IR values was determined in the study. The soil in the study area showed heavy Cd pollution, whereas the pollution by other elements was relatively slight. When the proportions of grain samples in which the concentrations exceeded the tolerance limits were examined, the grains were primarily contaminated with Pb, Ni, Cd, and Zn; and less contaminated with Cu and Cr. The drinking water of the local inhabitants was safe. The average IR value was 3.53 for adults and 3.91 for children, indicating that both adults and children may experience adverse health effects. The spatial distribution pattern of the IR values among the exposed populations in the study area showed high values in the eastern and middle parts, with maximum values >5, and low values in the western part, with minimum values <2. This is consistent with the distributions of the industries and the population. The study may provide a basis for comparison to other regions both in China and worldwide.

In this research microbiological status of water from three wells in a particular food factory was investigated. In raw water samples total number of aerobic mesophilic bacteria was determined with two methods - standardized and Petrifilm method which is in Serbia still an alternative method. Number of population of aerobic psychotrophic bacteria was also tested. ATP level was also analyzed. For classical microbiological method and quick method of evaluation of microbiological status correlation was reseached. Results show that coefficient of correlation was higher than 0.99 for the two applied methods. In most water samples the higher number of bacteria formed colonies when Petrifilm method was used. Connection between number of bacteria and level of total and free ATP is not statistically significant, while connection with variation of these values can be described as high direct linear correlation.
