Concentrations of heavy metals in the soil such as: (Pb, Cd, Zn and Cr), play a role in contamination of agricultural crops such as wheat (Triticum aestivum L.). Roads in the Republic of Kosovo are congested with traffic; in addition, over 55% are more than 20 years old. The agricultural land near roads in Kosovo is cultivated with agricultural products, especially wheat. This study aimed to investigate the concentration of toxic metals in soil and wheat crops due to vehicle emissions. In this research are examined the physico-chemical factors that affect the mobility of metals in the soil of the research area as; pH, concentration of organic carbon and heavy metals such as: (Pb, Cd, Zn and Cr). Analytical research shows that the content of toxic metals decreases with increasing distance or along highways. The concentration tests of toxic metals near roads and lands planted with analyzed agricultural crop of corn showed that heavy metal deposits also depend on atmospheric conditions and emissions from vehicle traffic.

The purpose of this research is to determine the content of heavy metals in the lakes of Kosovo, lakes with heavy metals such as: (Hg, Cd, Pb, As, Fe, Zn, Ni, Cu), in water and water sediment in Lake Radoniq and Lake Badovc. Determination of heavy metals (Pb, Cd, Hg, As), in muscle tissue and fish organs. Parameters as an indicator of fish safety for food, indicator of environmental pollution (Kosovo lake bioten). Age of fish, the amount of fat are important factors that affect the accumulation of heavy metals in fish. This indicates that the bioaccumulation of heavy metals is a special process and indicates the concentration of heavy metals in the body of the fish. The high concentration of Fe in fish organs is of particular importance for hemoglobin and its role in fish. Metal indicators such as biocumulation factors are different, for example, for Pb can be increased with high concentrations compared to international parameters which depends on the species of fish and the location of catching s137 fish, the concentration of heavy metals in the Lake and the impacts from agricultural activities. The concentration of heavy metals in the body of aquatic life depends on the way in which heavy metals penetrate, giving the body the opportunity to detoxify them through metabolism. Metabolism means the exchange of substances, the uninterrupted exchange of matter between the living organism and the external environment. This process is the basis of life, which allows a cell to grow and reproduce, maintain its structure and respond to its environment.

From March 2020 to early June 2020, Kosovo introduced various travel restriction measures for foreign nationals, including entry bans, closure of land and air border crossings, two-week quarantine, and self-isolation. From March to May, the country was almost completely blocked, where the activities of the tourism industry were strictly prohibited while businesses encountered great difficulties to operate and provide services, the number of jobseekers in the country increased significantly, precisely because of the cessation of activities, because this sector is considered to be one of the sectors that contributes the most to employment in our country, despite the fact that some of these businesses are family businesses. A significant number of employees in these sectors in our country may lose their jobs, as a result of the situation created, and this will further deepen the tourism industry, mainly due to the decline in the volume of remittances and tourism diaspora in Kosovo. While restrictive measures may have had a positive impact on curbing the spread of the virus, and preventing the escalation of the health crisis, the effect and consequences of closing the economy for months is severe for the tourism industry.

Abstract:Concerns and uncertainty about the life on Earth are constantly growing, today greater than ever before, as a result of human activity. In this regard, the major dangers that threaten our planet include uncontrolled utilization of natural resources, environmental deterioration and environmental pollution over Earth's regenerating possibilities. Whereas, the main causes of pollution are deforestation, erosion, greenhouse gas emissions, poor urban and industrial waste control and uncontrolled mining activities. All of these lead to serious consequences for life on Earth, because of the natural resources of the soil and its capacity to absorb waste gases (CH4), and the release of heavy metals such as Pb, Zn, Cd, Cu, Fe and As, which are the biggest soil pollutants. The Earth is being cemented, and its regenerating capacities are being diminished every day.UDC Classification: 502/504; DOI: http://dx
