Water, being an essential element for the survival of living organisms, requires to be free from contaminants and pollutants. These contaminants are generally of organic, biological, microbial or inorganic nature, and all these contaminants pose severe hazards to human health upon consumption through the water. The high concentration of heavy metal ions is being found in water resources owing to the ever-increasing anthropogenic as well as industrial activities. Some of the heavy metals are crucial for the development and functioning of the human body, whereas some are toxic. In any case, consumption of any heavy metal beyond the accepted guideline values can lead to the rise of health complications. Researchers are effectively using magnetic nanoferrites as nanoadsorbents for water treatment. Specially designed magnetic nanoferrites have been found to provide as high as 99% elimination of selective heavy metal ions from the contaminated water. The present study reviews the recent researches conducted in the last two decades in the area of health hazards posed by prolonged consumption of heavy metal ions through consumable water and about using magnetic nanoferrites, their composites and derivatives for efficient removal of different kinds of heavy metal ions.

水是生命有机体生存的基本要素，它必须不含污染物和污染物。这些污染物通常具有有机，生物，微生物或无机性质，并且所有这些污染物在通过水消耗后对人类健康构成严重危害。由于人类活动和工业活动的不断增加，水资源中发现了高浓度的重金属离子。有些重金属对人体的发育和功能至关重要，而有些则有毒。在任何情况下，任何重金属的消耗都超过了可接受的准则值都可能导致健康并发症的增加。研究人员有效地使用磁性纳米铁氧体作为纳米吸附剂进行水处理。业已发现，经过特殊设计的磁性纳米铁氧体可从污染水中去除高达99％的选择性重金属离子。本研究回顾了过去二十年来在通过饮用水长期消耗重金属离子所造成的健康危害方面的最新研究，以及有关使用磁性纳米铁氧体，其复合物和衍生物有效去除各种重金属离子的健康研究。 。
