|
Effects on plants : |
Conifers were exposed to NH3 for 50 days (in winter, open-top
chambers): 0.42 mg NH3/m3 (95 perc.) - 0.25 mg NH3/m3 (mean)
(0.61 ppm - 0.36 ppm) caused heavy injury e.g. sharply bondered
necrotic tip of the older needles of Taxus baccata.
No-adverse-effect level for some months exposures: 0.2 mg/m3
(0.3 ppm).

Other effects on aquatic ecosystems : |
Impact on biodegradation processes: 2.0 mg/l affects the
selfpurification of water courses (Verschueren 1983).

Other information : |
Ammonium ion is less toxic then ammonia appearing at high
pH-values.
