“…Environmental contamination due to mercury is caused by several industries, petrochemicals, minings, painting, and also by agricultural sources such as fertilizer and fungicidal sprays [26]. Some of the more common sources of mercury found throughout the environment include but may not be limited to the household bleach, acid, and caustic chemicals (e.g., battery acid, household lye, muriatic acid (hydrochloric acid), sodium hydroxide, and sulfuric acid), instrumentation containing mercury (e.g., medical instruments, thermometers, barometers, and manometers), dental amalgam (fillings), latex paint (manufactured prior to 1990), batteries, electric lighting (fluorescent lamps, incandescent wire filaments, mercury vapor lamps, ultraviolet lamps), pesticides, pharmaceuticals (e.g., nasal sprays, cosmetics, contact lens products), household detergents and cleaners, laboratory chemicals, inks and paper coatings, lubrication oils, wiring devices and switches, and textiles.…”

Heavy metals are among the most important sorts of contaminant in the environment. Several methods already used to clean up the environment from these kinds of contaminants, but most of them are costly and difficult to get optimum results. Currently, phytoremediation is an effective and affordable technological solution used to extract or remove inactive metals and metal pollutants from contaminated soil and water. This technology is environmental friendly and potentially cost effective. This paper aims to compile some information about heavy metals of arsenic, lead, and mercury (As, Pb, and Hg) sources, effects and their treatment. It also reviews deeply about phytoremediation technology, including the heavy metal uptake mechanisms and several research studies associated about the topics. Additionally, it describes several sources and the effects of As, Pb, and Hg on the environment, the advantages of this kind of technology for reducing them, and also heavy metal uptake mechanisms in phytoremediation technology as well as the factors affecting the uptake mechanisms. Some recommended plants which are commonly used in phytoremediation and their capability to reduce the contaminant are also reported.

“…Among the various matrixes that are available, the MC has been chosen for its ease of use, low economic cost, low toxicity, and high operational stability (Rezaee et al, 2005;Son et al, 2003). The MC synthesized by Acetobacter xylinum is identical to that made by plants in respect to molecular structure.…”

The purpose of this study was to investigate the immobilization of denitrifying bacteria on microbial cellulose (MC) for biological denitrification. A novel denitrifying bacterium, Pseudomonas stutzeri, was immobilized in microbial cellulose and introduced into an up flow packed bed reactor in order to remove nitrate from synthetic influent. The MC presented the high biomass concentration throughout the experiment, achieving 3.4 mg biomass/g support. The efficiency of the system for denitrification was tested under different running conditions. Complete biological denitrification of the synthetic effluent was achieved at low hydraulic residence times, less than 4 h, and high nitrate concentration (200 mg NO 3 -N/L). The immobilization of the bacterium in MC increased the adsorption capacity, decreased the cell leakage from the beads, resulted in higher activity of the immobilized cells, and allowed better operational control.

“…The possible noticeable effects of mercury in birds are decreased egg weight, fertility, and hatchability. Increase in kidney lesions, brain lesions, skeletal deformities; reduced clutch size, poor hatchability, poor embryonic growth, behavioural change and neurologic signs of weakness and inadequate coordination in wild birds [57]. It has also been demonstrated that the occurrence of deformities increases rapidly when selenium concentrations in fish eggs are greater than 10mg/kg [58].…”

This review aims to give all-inclusive précis of key roles of wild birds as bioindicators of contamination using theoretical and empirical evidence provided in different literature and its influence on conservation. Over the years wild birds have been used as bioindicators of contamination globally. Are wild birds suitable for measuring heavy metal pollution? Bioindicators are species used to appraise the health conditions of the environment and they are capable of determining the environmental integrity if their functions and populations are put into consideration. Birds are good indicators because they are very easy to detect and their presence is easy to observe in any environment or if the habitat does not fulfill the ecological requirements, as they are equipped with the ability of flight so that they will leave the environment. Apart from that, in classification individual species are easy to identify with their wide distribution. Heavy metals are essential elements for organisms but may be toxic with high level, affecting productive function and behavioural features and equally heavy metals can easily be accumulated and biomagnified through food or food web. Therefore, using birds as bioindicators is a function of properties of interest and resources available for ecological evaluation which promotes conservation of bird species for impending generation.
