Assessment of phytoremediation ability of Coriander sativum for soil and water co-contaminated with lead and arsenic: a small-scale study

Abstract

A study was conducted to access the phytoremediation potential of Coriandrum sativum for lead (Pb) and Arsenic (As). Metal tolerance index and pot experiment were conducted. Viable seeds were spread on filter paper and planted in soil placed in pots. The amount of Pb and As in control and in tailing soil was 0.27, 0.141, 1.77, and 0.35 ppm. The study was carried out in triplicates for a period of 4 weeks under natural conditions. The physico-chemical properties of soil were determined using the standard methods. Germination of seeds of Coriander sativum was inhibited more rigorously in filter paper as compared to soil medium. Shoot height and root length were significantly reduced in filter paper medium under Pb and As stress. These were inhibited by 33 and 40%, respectively, from the first to fourth weeks. Seedling growth was less affected in soil medium while greatly reduced in filter paper medium. Soil sustained almost equal stress in the fourth week as compared to the third week in filter paper medium. Shoot height was enormously affected by Pb and As compared to root length in filter paper medium, whereas slight inhibition of growth was observed in soil medium. Coriander sativum grown in pots was effective in removing Pb and As from control and tailing soils in comparison with seeds grown on filter paper. On this basis, it could be used in restoring soil polluted with Pb and As.

Lipid profile improving effect of Coriandrum sativum seed extract in rats

“…The study recommended that the whole plant of coriander from seeds, leaves, and stalks seems to be a promising natural chelating agent for toxic heavy metals. 13 The data may be supported by those reported by Donia who found that coriander increased the serum levels of vasodilator factors (PGI2, NO, and eNOS), decreased Na+ retention and serum uric acid (UA) level, and ameliorated glucolipid profiles in highfructose and high-salt diet-induced hypertension by mitigating abnormal changes in vascular endothelial function, renal and intestinal sodium absorption, glucolipid homeostasis, and gut microbiota in rats. 48…”

“…8 Different types of extracts from different parts of the plant have been shown to exhibit pharmacological effects, including, antioxidant, cardioprotective and antatherosclerotic effects in diabetic patients, growth promoting and improved carcass yield in broilers, stomachic and aphrodisiac effects, and antidote for heavy metals as arsenic and mercury. [9][10][11][12][13] The present study was designed to evaluate the antihyperlipidemic effect of C. sativum seed extract (CSSE) in albino rats fed on high-fat diet. To fulfil this aim, the following objectives have been conducted: the effect of CSSE on lipid biomarkers as total cholesterol, triglycerides and lipoproteins; the effect of CSSE on biomarkers indicating hepatic (total protein, bilirubins, aminotransferases), renal (urea, creatinine, uric acid) and cardiac (creatine kinasemyoglobin biomarker, troponin-I) dysfunction; and the qualitative phytochemical analysis of CSSE to determine the active principles underlying its effect.…”

Phytotoxic and Genotoxic Effects of Copper Nanoparticles in Coriander (Coriandrum sativum—Apiaceae)

“…Adsorption capacity and efficiency of coriander in removal of Pb 2+ , Cd 2+ ions and turbidity from simulated contaminated water was reported [25]. Additionally, C. sativum plants showed considerable potential for phytoremediation of Pb and As from contaminated soil and water [26].…”

“…In order to evaluate the phytotoxic effects, the lengths of the roots and shoots of plants subjected to different concentrations of pollutants are measured. The tolerance index or elongation rate is calculated by relating the lengths of the roots/shoots of the pollutant samples to the lengths of the roots/shoots of the blank sample [27,28] (Eq. 3).…”
