“…Plants growing in HM-contaminated soils show visible symptoms like stunted growth, chlorosis, root browning, and sometimes even death [ 10 , 11 ]. Moreover, HM toxicity hinders the metabolic, cellular, and genetic potential of the plants required for normal growth and development.…”

A Comprehensive Review on the Heavy Metal Toxicity and Sequestration in Plants

Heavy metal (HM) toxicity has become a global concern in recent years and is imposing a severe threat to the environment and human health. In the case of plants, a higher concentration of HMs, above a threshold, adversely affects cellular metabolism because of the generation of reactive oxygen species (ROS) which target the key biological molecules. Moreover, some of the HMs such as mercury and arsenic, among others, can directly alter the protein/enzyme activities by targeting their –SH group to further impede the cellular metabolism. Particularly, inhibition of photosynthesis has been reported under HM toxicity because HMs trigger the degradation of chlorophyll molecules by enhancing the chlorophyllase activity and by replacing the central Mg ion in the porphyrin ring which affects overall plant growth and yield. Consequently, plants utilize various strategies to mitigate the negative impact of HM toxicity by limiting the uptake of these HMs and their sequestration into the vacuoles with the help of various molecules including proteins such as phytochelatins, metallothionein, compatible solutes, and secondary metabolites. In this comprehensive review, we provided insights towards a wider aspect of HM toxicity, ranging from their negative impact on plant growth to the mechanisms employed by the plants to alleviate the HM toxicity and presented the molecular mechanism of HMs toxicity and sequestration in plants.

“…Environmental pollution by toxic metals has increased steadily since the industrial revolution, thereby causing serious ecological problems [2,3]. Significant amounts of heavy metals and other chemicals are introduced into the environment particularly by industries amongst which the Cement Industry is a major player [4][5][6]. Cement manufacturing plants are known to produce a number of emissions which include particulate matter, gases and various heavy metals that are hazardous to the biotic environment with their impact often clearly manifested on soil and plants in addition to terrestrial and aquatic flora and fauna [7][8][9][10]; consequently affecting food quality and human health [11,12].…”

The negative consequence of industries in urban cities has become a major concern. Environmental risk assessment of heavy metals in the cement factories around Ewekoro environ was evaluated to deduce its risk on public health.Soil samples and consumable vegetables (Sugar-cane (Saccharumofficinarum), Soko (Celosia argentea), Cocoyam (Colocasiaesculerita) and Ewedu (Corchoruos olitorius) were collected 200m apart around the cement factory. Soil samples were dis-aggregated and sieved through a 65µ mesh sieve, then analyzed using inductively coupled plasma-emission spectrometry (ICP-ES), while plant samples were crushed and pulverized before being analysed using inductively coupled plasma-mass spectrometry (ICP-MS), all analyses were done at Acme laboratories Canada. Geochemical result of soils showed that most of the metals have values above the USEPA standard except Ni, V, Cr, and Ba, due to the effect of cement factory. Contamination factor and degree (C deg ) revealed extreme contamination of Zn and Mn. Inter elemental analysis showed a strong correlation between Cr-As ('r' = 0.872) and Ga-v ('r' = 0.936), which reflects the same anthropogenic source. Geochemical results in vegetables revealed Zn to be the highest metal accumulated, and that which is most contaminated is Ewedu (Corchoruos olitorius). A strong and positive correlation was found in Ba-Sr, and Cd-Zn with r > 0.9 showing the same anthropogenic source.Transfer factor(TF) revealed accumulation of metals by the vegetables. Analysis of the health implications of these heavy metals was carried out in some clinics around the area and the common diseases recorded are the ones generally associated with cement dust inhaling. Soils and vegetables Risk Analysis IX 133 of areas around the cement factory are contaminated with metals especially Zn and Mn, with a severe effect on the public health.

Denizli is one of the rapidly developing states in the West Anatolian Region of Turkey. Keeping this in view, 30 different plants were selected to study their potential as biomonitors of trace elements like Pb, Cd, Ni, Zn, Fe and Mn (μg g-1 , dry weight). The samples were collected from two different altitudes of Honaz Dagi, a mauntain overlooking at state of Denizli. The concentrations of trace elements were determined by flame atomic absorption spectrometry (FAAS). The mean concentrations determined at 1000 m altitude ranged between 0.273 to 0.488, 0.099 to 0.488, 0.306 to 0.682, 1.017 to 3.744, and 0.148 to 0.674 (μg g-1 , dry weight), of Pb, Ni, Zn, Fe and Mn, respectively. At 1600 m altitude, the values ranged between 0.225 to 0.534, 0.150 to 0.842, 0.234 to 0.905, 1.082 to 3.864 and 0.023 to 0.982 (μg g-1 , dry weight) of Pb, Ni, Zn, Fe, Pb and Mn, respectively. No Cd was detected at both altitudes.
