lected based in the name or CAS number of the suggested compound. Therefore,
a precise match of name and number is required and as shown in the
table above a poor availability of data is not uncommon. However, if the
compound is a slight modification of another compound or belongs to a
family of related compounds it is possible that useful information can be
obtained by searching for information on such compounds in a more comprehensive
project (e.g. in the case of quinidine carbonate).
Several of the inorganic compounds are salts of metals and may dissociate in
the hydrosphere. To some extent the lack of data on the selected compounds
may be ameliorated by using data on the parent metal. In the case of zinc
borate this is, however, somewhat complicated since both zinc and boric
acid may contribute to the combined toxicity.
The type of data that are missing varies between compound. Typically
missing data on the environment side are biodegradation data and bioaccumulation
data. On the health side a less clear pattern is observed.

The available data indicate that the triphenyl and tricresyl phosphates may
have low impact on health, but are quite toxic in the environment. Poor data
availability for the structurally related resorcinol prohibits conclusions regarding
the effect pattern.
For this compound only very few data was identified. The phosphonic acid
(dimethyl ester) appears acutely toxic at 13 mg/kg bodyweight in rats and
mutagenic effects has been reported. A formulation of the compound was
lethal to fish (LC 50 ) at approx. 1 ml/l (density unknown).
The data sets on these compounds are relatively limited. It appears that limited
toxic effects can be induced in mammals after exposure to high doses.
Aluminium trihydroxide is generally not toxic in the available tests. Both
metal-ions play a metabolic role in mammals, but the data for the metal-ions
indicates acute toxic levels for Al to fish and crustaceans at
