Because of their tremendous and long-lasting capacity to filter contaminants from the water that flows through them, natural wetlands are frequently referred to as \u201cearth\u2019s kidneys.\u201d Heavy metals in aquatic environments, such as lakes and rivers have been studied extensively because of their toxicity, persistence, and tendency to bioaccumulate. Many studies have shown that aquatic plants are sinks for heavy metals in aquatic ecosystems. Because of their capacity to accumulate heavy metals, several species of aquatic macrophytes such as H. verticillate and water hyacinth have been used to remove heavy metals from wastewater. The ability of aquatic plants to actively and passively absorb huge amounts of metals from water and\/ or sediment through multiple organs such as roots stems, and leaves makes these plants suited for heavy metal modifications in the aquatic environment<\/li><\/ul>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><a href=\"https:\/\/edukemy.com\/upsc\/upsc-essay?utm_source=Blog&amp;utm_medium=Banner&amp;utm_campaign=Essay\" target=\"_blank\" rel=\"noreferrer noopener\"><img decoding=\"async\" data-src=\"https:\/\/edukemy.com\/blog\/wp-content\/uploads\/2024\/06\/UPSC-Essay-Course-1280\u00d7300-1-3.svg\" alt=\"\" class=\"wp-image-42688 lazyload\" width=\"781\" height=\"182\" src=\"data:image\/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==\" style=\"--smush-placeholder-width: 781px; --smush-placeholder-aspect-ratio: 781\/182;\" \/><\/a><\/figure>\n\n\n\n<p>For UPSC Prelims Resources,&nbsp;<a href=\"https:\/\/edukemy.com\/upsc-cse-prelims-resource-centre\" target=\"_blank\" rel=\"noreferrer noopener\">Click here<\/a><\/p>\n\n\n\n<p>For Daily Updates and Study Material:<\/p>\n\n\n\n<p>Join our Telegram Channel \u2013&nbsp;<a href=\"https:\/\/t.me\/WithEdukemy4IAS\" target=\"_blank\" rel=\"noreferrer noopener\">Edukemy for IAS<\/a><\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>1.
