Jul 07, 2020 Plants have evolved to cope with the naturally low level of lead in the soil. However, they are not going to thrive in an area where mining tailings and buried lead-acid batteries pollute the soil with lead. Lead in the soil inhibits seed germination and seedling development. It can interfere with root and plant growth, leading to stunted plants.
