“…They are sponsors of metabolic abnormalities in organisms, particularly customers of food from plants from polluted soil. Environmental contamination from HMs mainly originated from sources like solid and liquid wastes, urban-industrial aerosols, industries, mining activities, and agriculture chemicals (Agbemafle et al, 2020). HMs toxicity could be detected in different degrees depending on its consumption route, chemical formula, dosage, tissue affinity, sex, and age of the host, as well as whether exposure is acute or chronic (Agbemafle et al, 2020).…”

Heavy metals (HMs) are harmful and lethal at negligible levels and non-biodegradable in the typical ecosystem and constitutes animal, human and environmental hazards. They are divided into toxic metals like Lead, Cadmium, Arsenic, etc. and essential elements like copper, zinc, manganese, iron, nickel and chromium. Additionally, could be categorized into two groups based on the natural and anthropogenic sources releasing origins. Population and industrial expansion led to food contamination with HMs. Poisonous metals can be transferred from irrigation water to agricultural soils, agricultural operations, air pollution, animal feed, and packaging materials. Toxic metals are non-biodegradable, non-thermos degradable, and exceedingly stable in the ecosystem; as a result, they quickly build in various foods. Metal pollution of many foods, including agricultural commodities, and animal protein sources such as fish, milk, meat, and eggs, poses a hazard to food safety and security. Toxic metal pollution of irrigation water, agricultural soils, plants, and animals result in their integration into the food chain, posing a health hazard to humans. Most metals are harmful to animals and humans and accumulate in several organs like the skeleton, hepatic tissue, spleen, and renal tissues. Metals have a deleterious impact on the production of plants and animals. As a result, several remediation strategies have become necessary to limit the hazardous HMs pathway into the food chain and the human body. Metal nanoparticles are employed in beneficial applications, although they are associated with specific hazards.

“…However, the pollution from human activities has contributed to the high occurrence heavy metals into the ecosystem [2]. The concern of environmental pollution from heavy metals mostly came from different sources such as urban-industrial aerosols, solid and liquid wastes, mining activities, industries, and agriculture chemicals [3]. According to Singh and Kumar [4], the concentrations of heavy metals in the soil around waste dumpsites are influenced by some factors including types of wastes, topography, runoff, and level of scavenging [4].…”

“…There are no guidelines proposed for waste disposal, which cause the mixture of the waste and create leachate that relocates into the soil and groundwater [11]. The decomposition of organic matter in municipal solid waste by micro-organisms results in hazardous liquids called leachate that consists of organic matter, macro-inorganic components, and heavy metals polluting both soil and aquatic environment [3]. Consequently, in developing countries, landfills with leachate are improperly managed, uncontrolled leachate flows and diffuses and penetrates into the groundwater, therefore, contaminating the surrounding environment and human being in the vicinity of the landfill [6,12].…”

“…Heavy metals pile persistently exists in the waste disposal at the environmentally threatening level. This results in unhealthy conditions and environmental problems due to the poisoning effects of heavy metals in plants and potential health implications to humans and animals consuming such vegetables [3]. Once heavy metals are introduced into the soil, they cannot be degraded either biological or chemical and can persist in the environment for a long time, therefore, they cause serious environmental pollution and harmful effects to ecosystem including bioaccumulation [12,14].…”

Waste disposal is a serious global environmental threat resulting in heavy metal pollution. Contaminated soil with heavy metals has become a concern for agricultural scientists because of the progress made in agricultural product safety. Heavy metals are metalloids with biological toxicity. The most common are arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), lead (Pb), and zinc (Zn). These metals exist throughout the terrestrial environment and produced from anthropogenic and natural activities. Recently, the landfills have been reported as persecutor to soil contamination, but still, there is no promising way proposed for the waste disposal management in some developing countries. This is the biggest threat to the soil, crops, and the communities living around the dumpsites. Soil polluted with heavy metals result in human health risks, groundwater pollution, plant phytotoxicity and decline in crop and soil production. Absorption of heavy metals through plant roots is the major pathway in which heavy metals penetrate the food chain and their successive crowding along the food chain is a critical threat to animal and human health. The previous findings reported that soil, vegetables, and other food crops around dumpsites are contaminated with heavy metals. The soil contaminated with heavy metals is a leading cause of vegetables and other crops contamination, which is a cause of adverse health outcomes in developing countries' cities. Therefore, there is an urgent need for continuous monitoring of heavy metals in different open dumpsites. The necessary measures to reduce the high concentration of heavy metals in the soil and crops should be put in place. This paper aimed to review the harmful impacts of heavy metal contamination to the soil and crops grown in the vicinity of dumpsites, but also several techniques treating heavy metals pollution in the soil were discussed in this review.
