Undeveloped countries stopped using lead way after the USA. Lead contamination was a huge issue in Africa and the Middle East. It wasn't until 2014 that lead use in auto fuel was ended worldwide.
Luckily lead is very heavy and chemically active which makes it much easier to remove from soils than some of the nastier contaminants. You can essentially break it down with sulphur amendments to acidify the soil and then let the plants do the rest of the work. Eventually dilution does the rest of the work until it reaches background levels.
