تأثير المواد الدبالية في خفض سمية الرصاص في التربة

الملخص EN

When humic material was added to agricultural soil, the reduction of lead concentration in the soil was noticed.

This could be attributed due to the formation of lead complex compounds where these complexes have the ability to strongly combine with lead.

It was found that the use of absolute humic material has greater effect in comparison to a process using the humic extracts.

When different concentrations of lead nitrate were added to the soil, followed by adding the humic material or its extracts, the same results were obtained.

A spectrophotometer (Vario 6) was used to read the concentrations of lead in the soil during the study process.
