7439-92-1
Properties
- heavy metal
- metallic, as salt or in compounds
Main sources
- road and air transport (traces of lead in petrol)
- waste incineration
- corrosion protection work
- ammunition containing lead
Thresholds for the reporting requirement of facilities in accordance with Annex 2 PRTRO
(Ordinance on the Register relating to Pollutant Release and the Transfer of Waste and of Pollutants in Waste Water)
- Air 200 kg/year
- Water 20 kg/year
- Soil 20 kg/year
Impacts
- harms blood formation and is detrimental to children’s development
- damages plants and animals
- accumulates in the food chain
- reduces soil fertility
Ambient limit values
In particulate matter (PM10) 500 ng/m3 annual mean (arithmetic mean)
In dust fall out 100 µg/m2 day annual mean (arithmetic mean)
Measures
- introduction of unleaded regular petrol (1985)
- flue gas cleaning system
Status and changes
Since the 1970s, lead emissions have fallen sharply. Concentrations of lead bound to particulate matter have decreased significantly since 1988 at all sites. As a rule, the measured heavy metal loads are way below the limit values of the Ordinance on Air Pollution Control.
