While lead in petrol has been phased out, lead poisoning can still occur from various industrial and consumer products. Smelting operations, particularly for metals like lead, zinc, and copper, can release lead into the environment. Lead-based paints, especially in older buildings, pose a significant risk when they deteriorate or are disturbed. Although the use of lead in cosmetics and hair dyes has decreased due to regulations, some products may still contain trace amounts, but industrial sources and paints remain the primary ongoing concerns after petrol.
