This paper presents an integrated environmental management plan for soil quality control in the city of Novi Sad in the Republic of Serbia. Considering the very favorable geographical position, Novi Sad is a city that interweaves important main roads, has population increase, as well as the rapid development of industry and agriculture. Due to these facts there is also increased pollution of air, water and soil, as well as generation of large waste amount. In addition to parks and devastated areas around the industrial zones, widespread agricultural activity in suburban areas is particularly sensitive to the soil quality and vice versa. In this study, the geographical position and geomorphological characteristics of the city area, as well as the leading ecological problems, were analyzed. Based on the given facts, an integrated monitoring of one of the environmental quality indicators, the soil quality was proposed. There was suggest the network of 15 sensors for measuring of pH value, humidity and soil temperature in the city area. Soil quality data obtained in this way in real time is very important for elimination or mitigation of potential undesirable consequences. Thanks to the rapid development of technology, the utilization of sensors network is increasingly being used in modern monitoring systems and is available for efficient and cost-effective solution of environmental problems.

The modern way of life and aspiration for faster technological development creates increasing problems related to waste quantities and management. Waste management is a complex process due to the constant danger to the environment through pollution of air, water and soil as well as the human health. Lack of waste quantity, composition and location informations makes disposal and categorization process more difficult, as well as its recycling or reuse. Industrialization and development of modern society and irrational usage of natural resources increases the amount of waste, which creates the need for an organized approach to this problem. In order to resolve these issues, among other, the constant monitoring, implementation of legislation and increasing public awareness are necessary. This particularly refers to the collection of reliable data on the quantities of generated waste, and its disposal within the local communities and protected areas. There is no systemic organized waste management in the Republic of Serbia for the time being. However, there is the long-term strategy in the field of environmental protection, which implies improving the population quality of life and preserving the nature, where an important place has the proper waste treatment.

UTILIZATION of WASTE MATERIALS in HEAVY METALS and RADIONUCLIDES IMOBILIZATION by SORPTION the researching trend of sorption characteristics of various natural materials, i.e. easily accessible raw materials, by-products or waste from various types of industry in recent years has become more pronounced. Waste materials utilization reduces the exploitation of natural non-renewable resources and/or exploitation of various forms of energy for synthesis or modification of natural raw materials and artificial materials. Also, the utilization of waste materials as sorbents is extremely acceptable from the aspect of environmental protection since it affects the amount reduction of such waste types, costs of their disposal and reduction of the hazards risks that some of these wastes can potentially cause in the environment. This paper presents an overview of the contemporary research of waste materials in heavy metals and radionuclides immobilization. Studies have shown that the usage of waste materials in the sorption process, i.e. conditioning of liquid radioactive waste and wastewater treatment can be very efficient and economically viable alternatives for standardly used methods, i.e. sorbents. Recent research on application of different waste materials and undemanding techniques for their modification due to sorption process improving include a wide range of waste materials, such as the various types of sludge, slag, fly ash, biomass, food waste, construction and demolition waste, etc.

This study presents generation, quantities and medical waste (MW) management in Serbia. It represents assessment methods and total annual MW generation by categories. It was concluded that pharmaceutical (64%) and infectious (32%) MW production is the largest. According to available data, MW management in Serbia is currently at low level, except when it comes to infectious waste. Research proposed simpler treatment methods in existing autoclaves and complex methods (incineration and plasma-pyrolysis), as well as short-term and long-term solutions. Predicted MW growing amount requires existing capacity increase for processing and new solutions application. Installed autoclaves capacity could be increased by increasing working time, in order to avoid additional investment. However, treatment in autoclave is only suitable for infectious MW. For other medical waste, which main fractions are pharmaceutical and chemical waste, there is no infrastructure. As temporary solution, pharmaceutical waste is treated abroad which in longer period is not financially feasible. Considering that MW treatment in Serbia currently is based on health facilities network equipped with autoclaves, as central (CTF) and local (LTF) treatments facilities for infectious waste treatment, it is recommended additional capacity implementation for treatment of non-infectious waste to this network, with simultaneous management level optimization of whole MW.
