Heavy metals are found in air pollution as a component of particulate matter. Major sources of these metals are combustion of fossil fuels, power plants, construction, mining, industrial and agricultural processes, traffic, tire abrasion and corrosion of vehicle parts. Although lead in petrol was phased out over 20 years ago, historically combusted lead is still present in London’s air and soil and remains an important pollutant.

Maternal exposure to some heavy metals during pregnancy have been associated with increased risk of child autism. Research suggests that effects in children can also include unhealthy brain development, reduced cognitive function and IQ levels, potential psychiatric disorders, higher risk of depression, impaired dexterity and memory function and cognitive disorders later in life.

These sculptures are children's nebulisers that have been cast into lead and copper.
