Responses of Chemical Functional Groups in Coleus Blumei Roots under Lead Stress with Exogenous Selenium Treatment Using 2-dimensional Correlation FTIR Spectra

Abstract

Lead (Pb), the most common heavy metal pollutant, has caused great concern as a result of its widespread occurrence, toxic nature, and long duration in biological systems [1]. It mainly originates from mining and smelting activities, Pb-containing paints, gasoline and explosives, cosmetics, storage batteries, fertilizers, herbicides, pesticides, and other industrial products [2-3], and from Pb-enriched municipal sewage sludge [4]. Though regulatory measures have been adopted
