Interactive Effects of Tetracyclines and Copper on Plant Growth and Nutrient Uptake by Eichhornia crassipes

Abstract

A hydroponic experiment was conducted to investigate the growth and nutrient uptake by water hyacinth (Eichhornia crassipes) under the combined stress of typical veterinary antibiotic tetracyclines (TCs) with copper (Cu). Although E. crassipes proved relatively high tolerance to the co‐contamination of Cu and TCs, the plant growth and nutrient uptake were significantly and interactively influenced by co‐contamination between Cu and TCs after 20 days of growth. The inhibitory effects of Cu or TCs were more evident on physiological parameters than morphological parameters. An increase in the concentrations of Cu or TCs in solution was associated with a greater decrease in plant growth and nutrient uptake. The growth of shoots and nitrogen (N) and phosphorus (P) uptake by shoots were less affected by Cu/TCs compared to roots. The inhibitory effect of TCs on plants growth and nutrient uptake was much stronger than that of Cu, but the opposite was true for N and P concentrations in plant tissues. The mixture of TCs with the low‐Cu showed a reduction in plant growth and nutrient uptake compared with the sole treatments of TCs; while the inhibition was alleviated with increases of Cu concentrations in solution. Therefore, the interactive effects of TCs and Cu should be taken into consideration to achieve a better knowledge on phytotoxicity and bioavailability of co‐contamination between antibiotics and heavy metals to aquatic plants.

Removal of heavy metals from wastewater by natural growing plants on River Nile banks in Egypt

“…Using macrophytes to treat wastewater is a cost-effective process due to a low cost of construction, operation, and maintenance. Phytoremediation is a known process that uses different types of plants to reduce and remove contaminants from soil and water (Akinbile & Yusoff 2012;Gupta et al 2012;Kumar et al 2012;Ugya et al 2015;Lu et al 2016;Prasad & Maiti 2016). Phytoremediation is also called green remediation, botano-remediation, agro-remediation, and vegetative remediation (Kumar & Chopra 2016).…”

The Multifaceted Function of Water Hyacinth in Maintaining Environmental Sustainability and the Underlying Mechanisms: A Mini Review

“…In addition, the adsorption and degradation of ciprofloxacin by WH has also been reported [ 50 ]. Moreover, WH can efficiently adsorb tetracycline, and interestingly, the addition of Cu 2+ into water improves the absorption efficiency of tetracycline [ 77 , 78 ]. This work simulates a real environmental scenario whereby multiple types of pollution exist simultaneously and examines the capacity of WH to tackle mixed antibiotic and heavy metal pollution, the results of which turned out to be promising and intriguing.…”

“…In addition, the high level of proteins and carbohydrates that exist in WH provide extensive chelating sites for metal irons and, therefore, enable WH to achieve good performance in heavy metal absorption, resulting from their abundant functional groups, such as carbonyl, carboxyl, hydroxyl, and so on [ 117 ]. Interestingly, the chemisorption of WH can be enhanced by metal ions, such as Cu 2+ , which forms a strong metal bridge on the root surface of WH under weak acidity conditions [ 77 , 78 ]. In addition to the above discussed chemisorption, some bioactive compounds in WH were supposed to work in the assimilation of organic pollutants, because the detached roots and the crude extracts of WH roots showed comparable adsorption [ 62 ].…”

Corrosion Inhibition Performance of Levofloxacin Hydrochloride for Mild Steel in Hydrochloride Acid Solution

“…Normally, common methods include neutralization process, porous materials to adsorb or membrane permeation to filtrate [5,6]. Ina few cases, plant absorption methods would be put to use [7], which would bring about a large amount of chemical and stuff loss. In addition, creature would be affected through the cycle chain [8].…”
