When I was younger fuel was labeled “unleaded” when they took the anti-engine knock chemicals out. There is some lead naturally in soil but it’s generally low levels UMass has a lead in soil fact sheet: https://ag.umass.edu/soil-plant-nutrient-testing-laboratory/fact-sheets/soil-lead-fact-sheet https://ag.umass.edu/soil-plant-nutrient-testing-laboratory/... “The US EPA has set a safe soil lead threshold limit of 400 ppm total lead using this method. The US EPA also recommends that soils used for gardening fall below 100 ppm total lead. In Massachusetts, the regulatory safety threshold is 200 ppm total lead….To reduce your risk of lead poisoning, the following is advised: Good Gardening Practices to Reduce Lead Exposure -Locate gardens away from old painted structures and heavily travelled roads. -Give planting preferences to fruiting crops (tomatoes, squash, peas, sunflowers, corn, etc.). -Incorporate organic materials such as high quality compost, humus, and peat moss. -Lime soil as recommended by soil test (a soil pH of 6.5 to 7.0 will minimize lead “
