Abstract
The consequences of heavy metal contamination are progressively degrading soil quality in this modern period of industry. Due to this reason, improvement of the soil quality is necessary. Remediation is a method of removing pollutants from the root zone of plants in order to minimize stress and increase yield of plants grown in it. The use of plants to remove toxins from the soil, such as heavy metals, trace elements, organic chemicals, and radioactive substances, is referred to as bioremediation. Biochar and fly ash techniques are also studied for effectiveness in improving the quality of contaminated soil. This review compiles amelioration technologies and how they are used in the field. It also explains how nanoparticles are becoming a popular method of desalination, as well as how they can be employed in heavy metal phytoremediation.
Highlights
Today, the world faces many problems, one of which is heavy metal (HM) pollution.During mining from ores, heavy metals are transported and these elements are released into the environment when mined for various purposes
Soil is a compound mixture and a non-renewable natural resource, as it can only be restored on a geological timescale. It can be defined as the loose inorganic or organic matter of the surface that assists as a natural habitat for terrestrial plants [2]
The different techniques used for tackling soil adulteration due to HMs, the HMs have been removed using biochar, fly ash, and bioremediation techniques and recent advances suggested in nanotechnology combined with bioremediation which were found to be more effective and some methods cheaper than other techniques were discussed
Summary
The world faces many problems, one of which is heavy metal (HM) pollution. During mining from ores, heavy metals are transported and these elements are released into the environment when mined for various purposes. Heavy metals causing soil pollution based on human actions such as mining, steelworks, and electroplating negatively affect human health and ecosystem stabilization [8,9]. This makes it possible to set repair standards for contaminated sites to more realistic and acceptable levels This depended on the scientific evidence that remediation actions themselves can have adverse effects (e.g., greenhouse gas emissions, air pollution, groundwater infection, and eutrophication), and the fact that stakeholders consider ‘sustainability’ as a necessity. We need such sustanaible amelioration methods which minimize modern society’s growing impact on environment, society, and economy [15,16,17].
