Other physicochemical properties :
In the neutral pH ammonia is in ionform and less toxic
than ammonia (Nikunen et al. 1986)

     (Verschueren 1983).
 
Effects on anthropods :
LC50, Baetis rhodani:
2.2 mg/l, 0.42d
1.9 mg/l, 1d
1.6 mg/l, 2d
1.4 mg/l, 4d
1.11 mg/l, 6.25d
LC50, Chironomus riparius:
3.2 mg/l, 0.42d

1.75 mg/l, 2d
1.36 mg/l, 4d
1.14 mg/l, 6.25d
(Williams et al. 1986).
 
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 information :
Ammonium ion is less toxic then ammonia appearing at high
pH-values.
