“…Generally, previous studies that used P. furfuracea and E. prunastri near an iron steel factory in the province of Karabük showed concentrations higher than those of R. pollinaria specimens found in the present study. Similar results of heavy metal accumulation on lichens were reported for different lichen species by many researchers (Nyarko et al, 2008) in recent years. AAS element analyses demonstrated that the content of toxic elements was higher in Ramalina pollinaria than in Evernia prunastri (Cansaran-Duman et al, 2011).…”

“…As reported by some researchers (Savva, 1998;Atienzar & Jha, 2006), the alteration in DNA fingerprinting is a useful biomarker in eco-genotoxicology. Lichens have been used as test organisms for environmental risk and impact assessment (Nyarko et al, 2008). They are usually considered as ideal early warning indicators of air pollution (Gries, 1996;Hamada & Miyawaki, 1998).…”

With fast economic development and industrialization, a vast range of genotoxic chemicals are produced and distributed into the environment. These chemicals adversely affect living organisms and often lead to serious diseases in human beings. Due to the highly conserved structure of the genetic material, it is possible to use a broad variety of species, including bacteria, yeasts, animals, and plants, in genotoxicity tests (Poli et al., 1999). In recent years, lichens have been used as good bioindicators of the genetic toxicity of environmental pollutants (Aras et al., 2010;Cansaran-Duman et al., 2011). Genotoxicity as a result of metal toxicity is also described to play a major role in DNA damage induction (Halliwell, 1990). Toxic chemicals induce several cellular stress responses and damage different cellular components such as membranes, proteins, and DNA (

“…Heavy metals are some of the deadliest pollutants and their concentrations in the environment have considerably increased owing to human activities [1]. Lee [2] and Ozden et al [3] have shown that five potentially toxic heavy metals, namely arsenic (As), cadmium (Cd), chromium (Cr), mercury (Hg), and lead (Pb), are the most dangerous and persistent pollutants.…”

Mercury Uptake and Transport by Plants in Aquatic Environments: A Meta-Analysis

The use of phytoremediation technology to remove heavy metal ions from aquatic environments or reduce their toxicity offers the possibility of restoring the ecological environment of polluted water bodies. Based on available literature on heavy metal absorption by aquatic plants, we conducted a meta-analysis to study the absorptive capacities of different plants as well as the factors that influence their Hg-absorption performance. Seventeen plant families, including Araceae, Haloragaceae, Hydrocharitaceae, and Poaceae, have a strong Hg-absorption capacity. The root systems of aquatic plants belonging to these families are primarily responsible for this remediation function, and only a limited proportion of Hg+ that enters a plant via the root system is transferred to other plant organs. Additionally, the diversity of plant life habits (e.g., floating, submerged, and emergent) and the water pH significantly influence the ability of plants to absorb Hg. It is expected that this study will provide a reference for the cultivation of aquatic plants for restoring the ecological environment of Hg-polluted water bodies.

“…The growing development of agricultural, industrial, and urban activities has largely increased the release of toxic substances such as heavy metals and organic compounds to environmental systems [1][2][3]. In particular, toxic heavy metals in air, water, soil, and plants have caused severe public environmental concern because of their severe adverse influences on human health [4][5][6].…”

The feasibility of rapid recognition of an Hg-contaminated plant as a soil pollution indicator was investigated using near-infrared spectroscopy (NIRS) and chemometrics. The stem and leave of a native plant, Miscanthus floridulus (Labill.) Warb. (MFLW), were collected from Hg-contaminated areas ( 1 = 125) as well as from regular areas ( 2 = 116). The samples were dried and crushed and the powders were sieved through an 80-mesh sieve. Reference analysis of Hg levels was performed using inductively coupled plasma-atomic emission spectrometry (ICP-AES). The actual Hg contents of contaminated and normal samples were 16.2-30.5 and 0.0-0.1 mg/Kg, respectively. The NIRS measurements of impacted sample powders were collected in the mode of reflectance. The DUPLEX algorithm was utilized to split the NIRS data into representative training and test sets. Different spectral preprocessing methods were performed to remove the unwanted and noncomposition-correlated spectral variations. Classification models were developed using partial least squares discrimination analysis (PLSDA) based on the raw, smoothed, second-order derivative (D2), and standard normal variate (SNV) data, respectively. The prediction accuracy obtained by PLSDA with each data preprocessing option was 100%, indicating pattern recognition of Hg-contaminated MFLW samples using NIRS data was in perfect consistence with the ICP-AES results. NIRS combined with chemometrics will provide a tool to screen the Hg-contaminated MFLW, which can be potentially used as an indicator of soil pollution.
