Seedlings die when soil
(sandy) concentrations
exceed 250 mg/kg dry
weight. Maximum BCF
factors low: 0.6 for
roots; 0.1 for shoots.
Residues >62 mg As/kg
DW in shoots are toxic,
and 3,300 mg/kg DW
usually fatal.
15 mg/l inhibits light
activation and photosyn-
thetic CO fixation in
chloropia3ts.
No lasting effect at 2.25
kg/ha. Some species de-
foliated at 6.8 kg/ha.
Significant effect, in-
cluding 75% defoliation
of oaks and death of all
pine trees, at 34 kg/ha.
Decreased yields at 1 mg/1.
Toxic at 25 mg/kg.

At 75 mg/1, 60% reduction in
phosphate transport and glu-
cose metabolism in 30 minutes;
at 375 mg/l, 100% reduction. 1
