In conclusion, based on the test results, when paint Normastic 405, Grey, is used as an interior surface coating for the holds of ships employed in the transport of grain, the risk of dry cargo contamination is unlikely.
No difference in concentrations of epoxy derivatives, volatile compounds (Butanols), Benzene, Styrene and Toluene could be observed between the wheat grain sample exposed to Normastic 405 and the non-exposed reference sample. All results were below the detection limit.
Traces of solvent residues Ethylbenzene, m,p-Xylene and o-Xylene were observed in the wheat grain sample exposed to Normastic 405 but not in the non-exposed reference sample. The observed amounts were below 1 ppm and do not exceed guideline values available for drinking water (WHO (2008). Guidelines for drinking water quality).
The suitability of paint Normastic 405, Grey, for use as an interior coating for the holds of ships employed in the transport of grain has been assessed from a toxicity point of view.
Exposure: A cylindrical container was constructed so that the paint coated sample plate formed the base of the cylinder with its coated side facing in.
Analysis: The selected chemicals are those that are likely to evaporate from the coating.
