Abstract
Vegetables are a common food source for human health. All vegetable crops are very important for serving different nutrients to humans. Vegetables absorb necessary nutrients and contaminants from the soil. The introduction of heavy metals into soil and aquatic bodies has become a serious problem around the world. Heavy metals are introduced into the environment through a variety of natural and anthropogenic activities. Irrigation with untreated wastewater is the main reason for the accumulation of heavy metals in vegetable crops. This untreated wastewater is released through different anthropogenic activities. Heavy metals have been removed from wastewater using different physical, chemical, and biological methods. Food security and human health have both been jeopardised in recent decades as a result of the contamination of food crops by various contaminants. This article addressed a brief review of heavy metals contamination in vegetable crops, human health risks, techniques for removing heavy metals, and some important current studies.
