Article Synopsis
- Ozone (O3), nitrogen dioxide (NO2), and sulfur dioxide (SO2) levels in the Retezat Mountains were low during the summer of 2000-2002, posing no toxicity threat to forest trees, while ammonia (NH3) levels increased in 2001 and 2002, hinting at higher nitrogen deposition.
- Over 90% of rain was acidic, with pH levels below 5.5, leading to increased soil acidity; while the crown condition of Norway spruce and European beech was generally good, defoliation rose from 9.1% in 2000 to 16.1% in 2002.
- Drought and frequent acidic rainfall during this time likely contributed
