Atmospheric Situation 

Step into a setting of quiet charm, where the balance of warmth and light clouds creates a tranquil scene. With calm air and gentle surroundings, the day feels both soothing and inviting:

    • Softly Clouded Skies: A delicate layer of clouds tempers the sunlight, casting a serene and peaceful glow.
    • Warm Embrace: The air carries a mild warmth, adding comfort to the environment.
    • Stillness in the Air: With no wind to stir the calm, the atmosphere is undisturbed and serene.
Situation
Holidays houses site, near the main traffic bridge to cross the river
                                                                                                                 
Ambient sounds
Quite a lot of ambient noise, caused by car traffic from the nearby main bridge that crosses the river
Small boats sailing
                                                                                            
Underwater sounds
The sound frequencies underwater are stable, only varied by small vessels far from our location.
                                                                                              
Considerations
The sound of traffic is continuous, which generates a permanent white noise background on the surface, not perceptible underwater.
The recreation area was almost empty at the time of the recording, so the supposed sounds generated by the inhabitants of the recreation area were nonexistent.

Water Analysis

The water quality of the Danube River at Novi Sad, sampled at Resort Ribarsko Ostrvo – NS1, largely complies with Serbian environmental standards. Most key parameters, such as Dissolved Oxygen (9.9 mg-O₂/L), Nitrates (1.1 mg-N/L), Nitrites (0.008 mg-N/L), Ammonium (0.1 mg-N/L), Total Phosphorus (<0.04 mg-P/L), BOD₅ (1.3 mg-O₂/L), Copper (1.9 µg/L), and Arsenic (1.4 µg/L), fall within the thresholds for Class I water quality. This classification signifies excellent ecological status, making the water suitable for uses like drinking water (with filtration and disinfection), bathing, recreation, irrigation, and industrial processes like cooling.

The only exception is the Total Organic Carbon (TOC), which places the water in Class II, reflecting good ecological status. While this slightly lower classification still meets standards, it allows for the same uses as Class I water under similar conditions.

For parameters not regulated by Serbian standards, such as Cadmium, Nickel, and Lead, a comparison was made using World Health Organization (WHO) guidelines. All these parameters were within WHO-recommended limits, further demonstrating the water’s overall safety and quality. This analysis confirms that the Danube River at this point supports both environmental health and human use effectively.
