“…2). Increases in air pollution in Kremenchug are also observed during the periods of biodegradation of cyanobacteria, which grow uncontrollably in the Dnieper under the conditions of climate change and increasing inflows of nitrogen and phosphorus compounds into surface waters (Nykyforov et al, 2016. However, the predominant sources of air pollution (about 60 % of the total) are the emissions from mobile sources .…”

The growth in the number of road transport is an integral part of Ukraine's development. At the same time, this is a significant negative factor affecting urban ecosystems. In the paper, the most significant aspects and criteria for their evaluation were identified to assess the negative impact of the transport company on the urban ecosystem. The impact of the Kremenchuk Motor Transport Enterprise on the urban ecosystem of the city of Kremenchuk (Poltava region) was assessed. The main pollutants in the region's air basin are stationary sources. However, the predominant sources of air pollution are emissions from mobile sources. The criteria for assessing the level of environmental safety of a motor transport enterprise were improved. The "Comprehensive assessment of the level of environmental safety of the motor transport enterprise" software tool was developed. It was established that under modern conditions, the level of environmental safety of the motor transport enterprise corresponds to the level of average safety. Comprehensive measures were proposed to ensure the regulatory status of the components of the urban ecosystem and environmental safety on the territory of the Kremenchuk Motor Transport Enterprise.

“…However, further disposal of the collected phytoplankton is preferable in a biogas plant. The reed, recommended for use for disposable nozzles, also has high methanogenesis during anaerobic digestion, which makes it possible to efficiently utilize the total biomass [17][18][19][20].…”

Intensive water consumption from surface sources leads to debit imbalance and high level of pollution, especially for wastewater discharges, including urban wastewater treatment facilities. Dissolved harmful and organic substances enter a large number of water bodies, which leads to harsh conditions for the survival of the rivers flora and fauna. A demonstrative indicator of environmental troubles is the intensive development of blue-green algae, which are a nutrient medium for cyanobacteria. Their productivity can be limited by hydromechanical capture. It is proposed to use a small-sized mobile vessel with a filter unit using replaceable cartridges and a pump. As a filter material, it is recommended to use crushed reeds. This technical solution allows the environmentally safe disposal of biomass, saturated with phytoplankton and heavy metal ions that are effectively absorbed. An equation of the distribution of concentrations of blue-green algae over the distance measured from the water surface is provided. The calculated data obtained from the proposed dependence allow us to determine the required level of immersion of the suction probes. The optimal time period in days for the operation of filtering units during summer season was revealed.

“…Unfortunately, due to the lack of source data, it is impossible to calculate the formation of POPs for the combustion of organic fuel by stationary sources. Significant, not yet evaluated POPs are released as a result of biodegradation of blue-green algae, the rapid uncontrolled development of which is observed under the conditions of surface water pollution by phosphorus and nitrogen compounds and general warming of these reservoirs as a result of climate change [Nykyforov et al, 2016;Malovanyy et al, 2016].…”

The environmental legislation in Ukraine is changing rapidly. These changes are related to the adaptation of Ukrainian laws to the requirements of the European Union. In this regard, the paper considers the unintentional production of Persistent Organic Pollutants (POPs) in the Odessa Industrial-and-Urban Agglomeration (next -Odessa agglomeration) in the context of new regulatory and legal requirements of Ukraine. In many countries around the world, the issue of pollution of environmental components by POPs has a large focus, because POPs pose a global threat to the environment and human health. The work aims to assess the main sources of unintentional production of POPs in the Odessa agglomeration during one year (2017), taking into account the new territorial features of the Odessa agglomeration. For the first time for Odessa agglomeration, the mass of POPs formed by main sources using the newest European methodological approach was calculated, sources of unintentional production of POPs on volumes of these substances were ranked, and their total mass of generation on the territory of Odessa agglomeration was calculated. The number of POPs molecules equivalent to 2,3,7,8-TСDD, which infiltrate into the air basin of the Odessa agglomeration, hence into the organisms of the agglomeration inhabitants, was calculated. The obtained results were compared with the allowable number per capita of the agglomeration, the relevant conclusions were drawn. Priority sources of unintentional production of POPs were identified, which allows taking appropriate preventive measures to reduce the scale of their generation.
