Nutrients, especially nitrogen and phosphorus compounds, are important for the growth of algae and higher plants, but in high concentrations can cause undesirable changes in aquatic organisms and seawater quality. Long-term measurements of selected nutrients in the Slovenian sea show that their concentrations have decreased significantly. Therefore, the ecological status of the Slovenian Sea is assessed as good to very good based on nutrients in recent years.

In the period 1960-2019, the mean sea level along the Slovenian coast increased by 11 cm. On average, this means by 1.8 mm/year and in the last 20 years by 4,4 mm/year. It is estimated that the increase of the middle sea level is affected by global see level increase, and in the last period also by extreme weather conditions in the region. In the last twenty years, at the Slovenian and in the Adriatic coast sea level has been rising faster than the European and global trends.

The number of inhabitants who live in the impact area of major roads outside urban areas has decreased. In 2017, around 16,000 fewer inhabitants were exposed to high noise levels throughout the day and during the night compared to 2012. In urban areas, the number of inhabitants who are exposed to road traffic noise has not decreased. The number of inhabitants who are exposed to high noise levels throughout the day has remained at the same level as in 2012 and is estimated at 64,000.

The number of inhabitants who live in the impact area of major railways outside urban areas and are exposed to rail traffic noise has not changed significantly in the past years. In 2017, around 7,000 inhabitants were exposed to high noise levels throughout the day and around 10,700 inhabitants during the night. Between 2012 and 2017, the number of inhabitants who are exposed to high rail traffic noise did not decrease.

The number of inhabitants who are exposed to high noise levels along major roads and railways in Maribor is gradually decreasing. In Maribor, in terms of inhabitants exposed, rail traffic is less significant noise source compared to road traffic, which is one of the most significant noise sources. It is estimated that approximately 16,400 inhabitants are exposed to high road traffic noise levels throughout the day.
