“…Physico-chemical properties can be used to place bioactive metals into two groups; redox-active metals (Cr, Cu, Mn and Fe) and non-redox active metals (Cd, Ni, Hg, Zn and Al) [ 140 ]. Redox active metals directly generate oxidative stress in plants which disrupt cell homeostasis, affects DNA structure and function, causes damage to the chloroplast and accessory pigments and eventually the cell is destroyed by the production of ROS [ 137 , 141 , 142 ]. Alternatively, oxidative stress is generated indirectly by non-redox active metals by several mechanisms which restrain antioxidative enzymes, or induces ROS-producing enzymes [ 137 , 143 ].…”

Environmental pollution from hazardous waste materials, organic pollutants and heavy metals, has adversely affected the natural ecosystem to the detriment of man. These pollutants arise from anthropogenic sources as well as natural disasters such as hurricanes and volcanic eruptions. Toxic metals could accumulate in agricultural soils and get into the food chain, thereby becoming a major threat to food security. Conventional and physical methods are expensive and not effective in areas with low metal toxicity. Bioremediation is therefore an eco-friendly and efficient method of reclaiming environments contaminated with heavy metals by making use of the inherent biological mechanisms of microorganisms and plants to eradicate hazardous contaminants. This review discusses the toxic effects of heavy metal pollution and the mechanisms used by microbes and plants for environmental remediation. It also emphasized the importance of modern biotechnological techniques and approaches in improving the ability of microbial enzymes to effectively degrade heavy metals at a faster rate, highlighting recent advances in microbial bioremediation and phytoremediation for the removal of heavy metals from the environment as well as future prospects and limitations. However, strict adherence to biosafety regulations must be followed in the use of biotechnological methods to ensure safety of the environment.

Celem badań była ocena fitotoksyczności i fitogenotok-syczności warszawskich komunalnych osadów ściekowych zmieszanych z dwoma różnymi ro-dzajami gleb przy użyciu standardowych biote-stów roślinnych: Phytotoxkit i Allium cepa Root Tip Assay. Fitotoksyczność mieszanin osadów z glebami była zależna od koncentracji osadu i rodzaju gleby. W przypadku mieszaniny osadu z piaskiem już 3% koncentracja działała fitotok-sycznie, podczas gdy mieszanina z substratem torfowym wywoływała efekt fitotoksyczny dopie-ro przy 25-procentowym stężeniu osadu. Niestety przy tym, a także niższym (6%) stężeniu osadu w mieszaninie z substratem torfowym stwier-dzono silny efekt fitogenotoksyczny. Wydaje sięzatem, iż tak zwane biologiczne wykorzystanie badanego osadu ściekowego jest raczej ryzykow-ne dla roślin, szczególnie w przypadku gleb piasz-czystych, ale także organicznych.

“…These have similar characteristics to mammalian chromosomes and are inexpensive to perform various toxicity tests ( Abdelsalam et al., 2018 ; Salazar-Mercado et al., 2019 ). The plants mostly used as bioindicators in research related to cytotoxic and genotoxic tests are Allium cepa L. ( Martins et al., 2016 ; Haq et al., 2017 ; de Souza et al., 2017 ; Silveira et al., 2017 ; Braga et al., 2018 ; Verma and Srivastava, 2018 ; Heikal et al., 2019 ; García-Medina et al., 2020 ; Salazar and Quintero, 2020 ), Pisum sativum L. ( Salazar-Mercado et al., 2019 ), Lactuca sativa L. ( Andrade-Vieira et al., 2018 ), Zea mays L. ( Reynoso et al., 2015 ), Triticum aestivum L. ( Abdelsalam et al., 2018 ) and in recent studies Lens culinaris Medik ( Shahwar et al., 2019 ; Salazar and Maldonado, 2020 ; Salazar et al., 2020a ).…”

The present study aimed to determine the toxic effect of malathion pesticide on root growth, cell division and the chromosomal abnormalities frequency using the L. culinaris test. Initially, the lentil seeds were subjected to different doses of malathion (0.0 0.5, 1, 2.5, 5, 10, 15, 20, 25 and 30 mgL-1) and during 24, 48, and 72 h, the root length was measured. Subsequently, at 72h, the mitotic index, mitotic inhibition, and cellular abnormalities were calculated for all treatments. According to the obtained results, it was visualized that the root growth was inversely proportional to the concentration of malathion at all times of exposure. After 72h of exposure, the lowest values of the mitotic index and inhibition were presented at malathion concentrations 20, 25 and 30 mgL-1. Additionally, micronuclei cell abnormalities, metaphase sticky chromosomes, split chromosomes, nuclear lesions, irregular anaphase, anaphase bridges, binucleated cells, absence of nucleus and telophase bridge were observed. Finally, Malathion induced mitodepressive and cytotoxic effects in the meristematic cells of the L. culinaris root tip. A high frequency of abnormality was found in the micronuclei, which represented an indicator of a high degree of toxicity at the cellular level.
