About Lead

Category: Heavy metals and base cations

Lead is a very toxic element and can cause a variety of symptoms at low concentrations. Lead dust or fumes can irritate the eyes on contact, as well as causing irritation to the nose and throat on inhalation. Acute exposure can lead to loss of appetite, weight loss, stomach upsets, nausea and muscle cramps. High levels of acute exposure may also cause brain and kidney damage. Chronic exposure can lead to effects on the blood, kidneys, central nervous system and vitamin D metabolism. Emissions have declined by 98% since 1990. The largest source of lead until 1999 was from anti-knock lead additives in petrol. The use of leaded petrol contributed 74% of UK lead emissions in 1990, but leaded petrol was phased out from general sale at the end of 1999, and, consequently emissions from petrol decreased so that the contribution from 2000 onwards was just 1% of UK emissions  In 2016, the major sources of lead were steelmaking, with 32% of emissions, fireworks (13%) and combustion of waste oils by industry (10%). There has, however, been a significant reduction in emissions from steelmaking, at least in part due to declining production, and emissions from steelmaking in 2016 were  68% lower than in 1990. Emissions have also declined as a result of the decreasing use of coal.
