IBA - Is it dangerous?

If IBA is classed as hazardous does that mean it is dangerous?

The most likely reason for IBA being classified as hazardous would be excessive levels of certain compounds of lead, copper and nickel. Some compounds of these metals are toxic to plants, invertebrates and fish if significant amounts get onto land or into watercourses. This is called ‘ecotoxicity’. 

The Public Health England (formerly the Health Protection Agency) has considered the impact on health of municipal incinerators and indicates that there is little risk of public exposure to ash residues provided they are handled appropriately.

Research undertaken for ESA and shared with the Environment Agency has shown that the compounds of these metals in IBA are dominated by non ecotoxic compounds.
