Most baths (83%), ie fresh and salt water in the Old Continent, where people cool off in summer, are enough to meet the highest standards in the European Union.

They remained largely satisfactory, with a very low percentage of contaminated water, according to data released by the EU.

Of the countries in the region where the citizens of Serbia spend the most summer, the data show that it has the cleanest water. Greek. That is, 97.1% of baths have excellent quality water, while 99.1% of the water is good enough for bathing and there is almost no place with unsafe water. Follow her Croatia with 95.1 percent of baths with excellent quality water and none with drastically contaminated water.

“The current situation in Serbia is such that only about 10 percent of the wastewater is discharged, while the rest of the household and industrial wastewater is sent to rivers and other recipients without any treatment. This means that today everyone in Novi Sad and Belgrade, but also many other cities and settlements leave their toilets, kitchens and factories, go directly to rivers and other recipients and pollute them. Their achievement, “he explains by at Biznis.rs the chairman of the board of the Association “Environmental Protection Engineers” Igor Jezdimirovi.

According to the aforementioned Regulation, a legal person or entrepreneur who has wastewater treatment plants and / or discharges their wastewater to a public receiver or sewer, is obliged to harmonize its emissions with the emission limit values ​​of prescribed pollutants in water before December 31, 2025 at most … years.

It was also emphasized that agglomeration wastewater treatment plants with a load of more than 2,000 equivalent inhabitants (ES), which discharge municipal wastewater to the receiver, should harmonize their emissions with the limit values ​​of prescribed emissions before December 31, 2040 in recent years.

It is said that municipal wastewater, which is discharged into agglomerations with a load of less than 2,000 (ES), must adjust its pollutant emission limits in accordance with the water management plan. The Regulation also prescribes the rules according to which a legal person or employer should adopt and implement an action plan to reach the emission limit values.

When we return to EU research, it can be seen that, outside its borders, water quality is declining significantly. Thus, for example, a Albania, which is quite popular with tourists from Serbia this summer, only 76.5 percent of the beaches got an assessment of the excellent water quality. 95.8% of the water has a satisfactory quality and 4.2% of the baths have a very low quality.

“The wars for water have already begun. Water is a source of life and a strategic resource necessary for the development and life of the individual and the community. The rulers of Serbia betray and root out natural resources without plan and meaning, which often satisfy the interests of capital and with long-term consequences.Drinking water is one of the key problems in all of Serbia, especially in Vojvodina, and one of the incredible examples of negligence and irresponsibility of both rulers and private companies. is the village of Jazak in Fruka Gora, known for the water that can be bought all over Serbia.while water is sent from the territory of the village of Jazak everywhere in Serbia and beyond, methane has no water “It can happen if we, as citizens, do not become aware of the importance of the fight for a healthy environment and the natural resources that this country has.” Jezdimirovi.

The EU survey did not find any Montenegro, but the competent services of this country state that the water there is in 90 per cent of the locations of excellent, in 5.5 per cent of good and in 4.5 per cent of good of locations of satisfactory quality.

The Adriatic Sea has become saltier due to climate change

Judging by the results of research conducted by Croatian and Italian scientists, the Adriatic Sea has never been saltier. The result of research on hitherto unrecorded values ​​of Adriatic salinity was published in the journal Frontiers in Marine Science, which is in the top ten percent of journals in the field of marine biology and ‘water, the Ruer Bokovi Institute. recently announced.

The aforementioned research states that during the summer and autumn of 2017 extremely high values ​​of surface salinity (more than 39 per thousand) were recorded in the southern Adriatic and on the Palagruža threshold. This is the first time such high values ​​have been recorded in the Adriatic and they have covered the surface of the sea to a depth of about thirty meters. By the way, this phenomenon is common in the much saltier and warmer east, where the saltiest water in the Mediterranean is created, the so-called Levantine Intermediate Water.

This knowledge encouraged Croatian and Italian researchers to deal in more detail with the spatial and temporal extent of this phenomenon. The high salinity of this sea is partly due to the increase in the entry of high salinity waters from the East and the Ionian Sea, and partly due to the process in the Adriatic itself.

These processes take place on time scales from a few days to ten years and include four key phenomena. The first refers to the so-called Adriatic-Ionic bimodal oscillation, which otherwise causes strong oscillations of physical and biogeochemical variables in the Adriatic with a period of five to ten years, and in the last ten years causes a pronounced flow of salt and ultraoligotrophic. waters on the Adriatic. The second process is related to very low river flows up to one year before the appearance of high surface salinities, caused by the lack of rainfall in the wider Adriatic area.

The third process refers to the pronounced inflow of solar energy to the surface of the sea during summer and early autumn, when the climate is warmer than average and with little wind, ie with a weak vertical change of sea level and a stratification of water on a significantly warmer surface. layer and a half colder and layer at the bottom. Finally, the fourth process consists of a marked evaporation and loss of water from the sea surface.

Three of the four processes mentioned above have already been documented in the Mediterranean as a result of climate change, which in the future will lead to even hotter and drier summers, lower river flows and, consequently, stronger warming and salinization of the surface. of the sea.
