“…Pb accumulation in plants causes physiological problems, such as DNA damage and destroying root and shoot systems [114], and affects the enzymatic activities [115]. The effect of Pb toxicity on plants was studied by Nas et al [116]. The results indicated that a high concentration of Pb affected the fresh biomass and plant growth.…”

Environmental problems have always received immense attention from scientists. Toxicants pollution is a critical environmental concern that has posed serious threats to human health and agricultural production. Heavy metals and pesticides are top of the list of environmental toxicants endangering nature. This review focuses on the toxic effect of heavy metals (cadmium (Cd), lead (Pb), copper (Cu), and zinc (Zn)) and pesticides (insecticides, herbicides, and fungicides) adversely influencing the agricultural ecosystem (plant and soil) and human health. Furthermore, heavy metals accumulation and pesticide residues in soils and plants have been discussed in detail. In addition, the characteristics of contaminated soil and plant physiological parameters have been reviewed. Moreover, human diseases caused by exposure to heavy metals and pesticides were also reported. The bioaccumulation, mechanism of action, and transmission pathways of both heavy metals and pesticides are emphasized. In addition, the bioavailability in soil and plant uptake of these contaminants has also been considered. Meanwhile, the synergistic and antagonistic interactions between heavy metals and pesticides and their combined toxic effects have been discussed. Previous relevant studies are included to cover all aspects of this review. The information in this review provides deep insights into the understanding of environmental toxicants and their hazardous effects.

“…Lead is non-essential heavy metal and its accumulation in body at an elevated level and can causes headache, anaemia, damage of brain and central nervous system (Nas and Ali, 2018). Lead contents in present investigation were found in the range of 1.17 to 1.79 mg/kg.…”

T he pollution of our adjacent environment with heavy metals is becoming a big monster in many regions of the world especially industrial zones, metropolises and modern agricultural centres due totheir non-biodegrable nature, toxicity, bioaccumulation and subsequent bio-magnifications (Rahim and Mas Haris, 2019;Huihui et al., 2020). Any metallic element having a density greater than 5 g/cm 3 is referred to as a heavy metal. Rapid industrialization, anthropogenic lifestyle and the wide use of man-made chemicals are the major sources of metal toxicity in environment (do Carmo Ramos et al., 2016;. Elements such as Fe, Zn, Mn, Cu, Co and Ni plays a crucial role in the normal growth and some vital functions of living organisms if present in trace amount as micronutrients, however, becomes a matter of concern if exceed their permissible levels (Rahim et al., 2014;Zhang et al., 2020;Ilieva et al., 2020). Such metals become severely toxic beyond the threshold levels and can lead to various problems due to over-doses. Another list of metals including Pb, As, Cd, Cr and Hg also find their way into the surrounding environment through various anthropogenic activities and finally seep into living tissues through food chain (Ahmad et al., 2014;Krishna and Mohan, 2014). Such metals are of great concern for humanity since their long time exposure causes acute toxicities.

“…Under laboratory conditions, Jelea et al (2015) verified a reduction in germination with the increase in the concentration of lead nitrate. The decrease in the percentage of germination may be related to the interference of the metal in the activity of amylases and proteases (Nas and Ali, 2018;Boi et al, 2020).…”

This study goal to evaluate the effects of different concentrations of lead (Pb) and silver (Ag) on germination, initial growth and anatomical alterations of Lactuca sativa L. Plants use various mechanisms to reduce the impacts caused by anthropic action, such as xenobiotic elements of soils and water contaminated by heavy metals. These metals were supplied as lead nitrate and silver nitrate and the following treatments were established: control for both metals, maximum dose of heavy metals, for arable soils, allowed by the National Council of the Environment (Ag = 25 mg. Kg-1, Pb = 180 mg. Kg-1), double (Ag = 50 mg. Kg-1, Pb = 360 mg. Kg-1) and triple (Ag = 75 mg. Kg-1, Pb = 540 mg. Kg -1) of this dosage. Vigor and germination tests of the seeds and possible anatomical changes in the leaves and roots of lettuce plants were performed. The species showed a high capacity to germinate under Pb and Ag stress, and the germination was never completely inhibited; however, the germination decreased with increasing Pb concentrations, but not under Ag stress. The use of increasing doses of metals reduced seed vigor and increased chlorophyll content. An increase in biomass was also observed in plants from treatments submitted to Pb. The phytotoxic effects of metals were more pronounced at 15 days after sowing. Anatomically, L. sativa was influenced by metal concentrations, and had a reduction of up to 79.9% in root epidermis thickness at the highest Pb concentration, although some structures did not suffer significant changes. The results suggest that L. sativa presents tolerance to high concentrations of heavy metals, showing possible mechanisms to overcome the stress caused by these metals. In this research lettuce possibly used the mechanism of exclusion of metals retaining Pb and Ag in the roots preserving the photosynthetic apparatus in the aerial part of the plants. In general, the chemical element Pb was more toxic than Ag, in these experimental conditions.
