“…The seedlings in this study experienced a growth inhibition, after Cd treatments above 0.1 mM. Similar results were obtained by Liu et al (2012) where higher doses of cadmium lead to growth inhibition. Ghnaya et al (2005) also had at some degree a decrease in growth of Sesuvium portulacastrum and Mesembryanthenum crystrallum.…”

“…For example, Prodanovic et al (2012) showed inhibition rates around 80% in seeds of Serbian spruce (Picea omorika) with 1 mM of Cd 2þ ; also, Zhang et al (2010) registered inhibition at low concentration as 0.2 mM in Achnatherum inebrans. In Suaeda salsa, Liu et al (2012) had only 10% of seeds germinated after treatment with 0.05 mM of Cd, which was similar to the lower concentration used in the present study. These facts suggest that seeds of J. acutus could have a higher resistance to Cd-driven stress, than other studied species.…”

“…Enhanced activity of SOD and CAT was suggested as biomarkers of Cd-tolerance in Spartina densiflora (Martınez Domınguez et al, 2010) and Spartina alterniflora (Li et al, 2011). Notably, diminished activities of GPX and GST at high Cd level (2.0 mg L −1 Cd 2+ ) were reported to indicate an increased seedlingsenescence and plant-death in Suaeda salsa at the same Cd level (Liu et al, 2012). Increasing Cd-mediated decrease in the growth of Juncus effusus was indicated by a diminished activity of CAT (and also APX, and peroxidase) (Najeeb et al, 2011).…”

“…Exhibition of several oscillations in SOD activity but no change in CAT, APX, and GOPX were argued to indicate the response-modulating role of salinity stress in Zn-exposed H. portulacoides (da Silva, 2010). In contrast, under Cd-exposure, CAT was reported to exhibit no , a linear response (Liu et al, 2012) or elevated activity (Li et al, 2011). Enhanced activity of SOD and CAT was suggested as biomarkers of Cd-tolerance in Spartina densiflora (Martınez Domınguez et al, 2010) and Spartina alterniflora (Li et al, 2011).…”

As a major sink, estuarine/salt marsh ecosystem can receive discharges laden with myriads of contaminants including metals/metalloids from man-made activities. Two among the major consequences of metal/metalloid-exposure in estuarine/salt marsh ecosystem flora such as halophytic plants are: (a) the excessive accumulation of light energy that in turn leads to severe impairments in the photosystem II (PS II), and (b) metal/metalloids-accrued elevation in the cellular reactive oxygen species (ROS) that causes imbalance in the cellular redox homeostasis. On one hand, plants adopt several strategies to dissipate excessive energy hence eventually to avoid damage in the PS II and maintain optimum photosynthesis. On the other hand, components of the cellular redox system quickly respond to metal/metalloid-exposure, where plants try to maintain a fine-tuning among these components, and tightly control the level of ROS and its potential consequences. Herein, major insights into, and the significance and implications of important biophysical and biochemical markers in metal/metalloid-exposed halophytes are overviewed and also highlighted main aspects so far least explored in the present context. Discussion advocates to regularly monitor and integrate studies on the highlighted herein biophysical and biochemical markers taking into account the missing aspects such as essential and non-essential metal/metalloid-speciation, -availability, and -methylation, role of the obvious microbial activities, and a comparative account of the outcomes of the studies on mixture of metal/metalloid performed in laboratory and field conditions. Thus, consideration of these missing aspects in future studies on the subject can help us to: (a) unveil the status of the metal/metalloid-contamination and -impact; (b) understand adaptive responses of salt marsh halophyte to metals/metalloids, and also (c) to devise sustainable strategies for the environmental or ecosystem management and safety.

“…Heavy metals concentration was introduced due to the application of metals containing agrochemicals such as pesticides and fertilizers. Previous studies had showed that Hg, Zn, Cd, Co, Pb, Cu, As, Al, Cr, and Ni reduce the germination of many kinds of seeds [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16].…”

Heavy metal pollution was of considerable importance and relevant to the present scenario due to the increasing levels of pollution and its obvious impact on human health through the food chain [1]. It is a known fact that the widespread accumulation of metals in the environment is increasingly becoming a problem for organisms of every kind. The main sources of elevated heavy metals concentration in soils were agricultural, manufacturing, mining, waste disposal practices, and the use of sewage sludge as fertilizer in agricultural fields. Metal contamination of agricultural soil has increased parallel to industrialization. Heavy metals concentration was introduced due to the application of metals containing agrochemicals such as pesticides and fertilizers. Previous studies had showed that Hg, Zn, Cd, Co, Pb, Cu, As, Al, Cr, and Ni reduce the germination of many kinds of seeds [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16].Cadmium pollution was increasing in the environment due to mining, industrial usage, and many anthropogenic activities. Irrigation with polluted water had induced heavy metal accumulation not only in the soil but also in plant parts, including seeds and tissues [17]. Excess Cd caused a number of toxic symptoms in plant growth retardation and inhibition of photosynthesis. Cadmium could also enter the soil or water from spills or leaks at hazardous waste sites if Pol. J. Environ. Stud. Vol. 24, No. 1 (2015), [295][296][297][298][299] AbstractThe ecotoxicological effects of Cd 2+ on germination and early seedling growth of six pulses were investigated. Seeds of these plants were exposed to seven different concentrations of Cd (0, 0.1, 0.2, 0.4, 0.8, 1.6, and 3.2 mM). The results indicated that root and coleoptile growth of six pulse plants were more sensitive than seed germination for measurement of toxic Cd 2+ pollution. Different species show different levels of tolerance to Cd 2+ pollution. V. angularis and Dumasia villosa are the most sensitive to Cd 2+, and their germination percentage, and root and coleoptile growth were significantly lower than other tested species. By contrast, Vigna radiata and Lablab purpureus are the most resistant species, their germination and seedling growth almost were not influenced by Cd 2+ pollution significantly compared to control. There were significantly negative correlations between seedling growth and increasing concentrations of Cd 2+ for V. angularis. V. angularis and Dumasia villosa are the most sensitive to Cd 2+ . By contrast, Vigna radiata and Lablab purpureus are the most resistant species.
