**1. Introduction**

The contamination of heavy metals has spread widely across the environment, wreaking havoc on humans and the environment causing risks to the human race and hazard for the environment. A few hazardous Heavy metals (such as As, Pb, Cd, and Hg) relates to metabolic and other organic capacities as inconsequential. Certain metals, like Zn, Fe, Cr (III), etc., are important to carry metabolic cycles, including hemeproteins (like cytochrome p450) and catalysts. They are related to biota metabolism [1]. Despite the fact that metals like Nickel is an essential part of urease,

it poses a significant health hazard for the human populations [1, 2] Accordingly, food and soil, crop/vegetable frameworks have given an exemplary illustration of the biodiverse ecosystem communications in the climate. For food the basic source of yield is the soil, but it is prone to contamination by heavy metals from various origins (e.g., energy-serious enterprises, for example, nuclear energy stations and coal mine shafts, and chloro-soluble base synthetic ventures, like goldmines, purifying, electroplating, materials, calfskin, and e-squander handling) and nonpoint sources (e.g., soil/residue disintegration, farming spillover, and open cargo stockpiling). Notwithstanding their human wellbeing suggestions, Heavy metals unfavorably influences soil biota through microbial cycles [3]. For instance, restorative plants utilized for customary human medical care ought to be analyzed for Heavy metals tainting to forestall unfavorable impacts. When exposed to near refining or other modern environments, a variety of restorative species of plants have been found to cause bioaccumulation of various heavy metals (e.g., Cd, As, Cr, Cd, Cu, Pb, and Fe) [4, 5]. Both anthropogenic and natural sources release heavy metals into the environment. They can penetrate soils and groundwater, bioaccumulate in food webs, and harm biota because they are highly reactive and typically toxic at low quantities. The biotic effects of necessary and non-essential heavy metals are often highly distinct, and vary depending on the exact metal involved. This paper aims to provide a global overview of significant metal sources in agro-environments that are equivalent to the various anthropogenic activities and cycles [6]. This also includes details about heavy metals contamination in soil environments where food crops are grown in fully occupied main-lands. Moreover, ecological and lives of humans in these subsystems are needed to be discussed to aid in the understanding of the physiological/atomic systems which constitutes to the uptake of Heavy metals in the crops [7]. By suffocating or reducing the passage of metallic poisons from soil to food crops, management strategies are inextricably linked to human well-being government aid (soil-crop frameworks).
