After leaded petrol was phased out, major anthropogenic lead sources remain: (1) smelting/recycling of lead–acid batteries and other ores, and (3) architectural and industrial paints that still use lead-based pigments. Graphite ‘lead’ in pencils and modern pens contain no elemental lead, while lead compounds are now banned from hair oils/cosmetics in India, so statements 2 and 4 are not accepted.
