Low: If the lead present in your soil tests 400 ppm or below, the soil is safe for any use. Medium: Lead levels at 400 PPM and above fall into a medium risk range that increases in the amount of risk to an upper threshold of 1,000 PPM. High: If your lead level is above 1,000 PPM, use the area for something other than fruit and vegetable gardening.
Considering above facts, the objectives of this research were: (1) to study the phytotoxicity of lead on plant growth parameters; (2) to determine the accumulation and distribution of lead in plant parts growing on a lead-polluted soil, and (3) to identify a potential candidate for effective phytoremediation practice.

The leaves are covered with short, dense hairs. This covering gives a gray tint to the leaves, making the plant appear as have been dusted with lead. Thus the common name. Its roots can reach depths up to 4 feet and sometimes deeper. These deep roots help the plants survival during wildfires. Insects, Diseases and Other Plant Problems ...
According to one of my field guides, Lead Plant can live for centuries and not grow larger than 3 feet tall. Technically a shrub, the woody stems usually persist through winter but may die back and resprout in spring. The woody stems are also removed by fire but this species has very deep roots and survives fire well. It has its place in the ...
So, just to summarize, all lead weighted bunched oxygenating plants require silt/ substrate in which to root into, with the exception of Ceratophyllum Demersum (Hornwort). Any oxygenating …
Soil Lead Contamination Lead is naturally present in all soils. It generally occurs in the range of 15 to 40 parts lead per million parts of soil (ppm), or 15 to 40 milligrams lead per kilogram of soil (mg/kg). Pollution can increase soil lead levels to several thousand ppm. The major cause of soil lead contamination in populated areas is the weathering, …

There is a possibility that not all the lead in plant weights used nowadays is genuine lead. On the other hand, it would be advisable to substitute them with other types of weights, as mentioned earlier. Most metal weights are no longer composed of lead, despite the fact that they are still widely referred to as "lead weights" in this hobby

Plants get water from the soil through root system when their water potential is lower than that of the soil they grow in. Excess soluble salts (such as Na +) in the soil reduce the water potential of the soil around the root surface, thereby limiting water availability for the plant and reducing plant water uptake (Van Zelm et al., 2020).In this …
Also keep in mind that these plants may not remove all of the toxins from soil in one growing season. Lead tends to remain in soil for a very long time, which makes it harder to remove from your soil. Factors such as the rate of growth of the plant and the amount of lead in your soil will influence how long it takes to fully clean up a site.
