Sound Analysis

Date:  06.09.2024

Time: 14.00 hrs                                                                                                                   

Atmospheric Situation:

Step into a serene setting where warmth and subtle clouds create a perfectly balanced environment. The calm air and gentle ambiance invite you to pause and enjoy the moment:

  • Softly Overcast: A touch of cloud cover diffuses the sunlight, casting a gentle, muted glow over the surroundings.
  • Warm Embrace: The air carries a comfortable warmth, creating a cozy and inviting atmosphere.
  • Peaceful Calm: With no wind to stir the scene, the stillness amplifies the soothing vibe of the day.
Situation:
Small recreational area near the river, apparently not in use.
                                                                           
Surface sounds
The construction of a new bridge nearby Makes constant machinery noise
In addition, several large cargo ships navigate the river
Bird sounds
                                                                                                                                                                            Underwater sounds
Stable frequencies reflecting the current of the water.
Perhaps, because of the direction of the current and the location of our sampling position, the sounds of the outside machines are barely perceptible underwater.                                                                                                                                        
Considerations
Is the only place where we capture bird sounds, as there was a colony on the small island in front of the location.

Water Analysis

The water quality of the Danube River at Novi Sad, sampled at Burma Beach – NS3, is largely in line with Serbian environmental standards. Most key parameters, including Dissolved Oxygen (9.2 mg-O₂/L), Nitrates (1.1 mg-N/L), Nitrites (0.014 mg-N/L), Total Phosphorus (<0.04 mg-P/L), BOD₅ (1.5 mg-O₂/L), Copper (3.2 µg/L), and Arsenic (2.8 µg/L), meet the criteria for Class I water quality. This signifies excellent ecological status, meaning the water is well-suited for uses such as drinking (with treatment), bathing, recreation, irrigation, and industrial cooling.
However, two parameters—Total Organic Carbon (TOC) and Ammonium (0.3 mg-N/L)—place the water in Class II, which corresponds to good ecological status. While this is slightly below Class I, the water remains suitable for the same uses, with minimal additional treatment required.

For parameters not regulated by Serbian standards, such as Cadmium, Nickel, and Lead, the assessment was based on World Health Organization (WHO) guidelines. All these parameters were well within the recommended limits, indicating no significant risks.

This analysis highlights the Danube River’s overall ability to support environmental and human needs effectively, though continuous monitoring and localized management may help address minor exceedances to further maintain water quality.

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.
