For a long time, there are many factors that destroy the aquatic environments. The environment and health effects has been going down lately, especially aquatic environments because of heavy metal toxicity. The freshwaters have always started off with low concentrations of heavy metals. Even though the toxicity is base concentrations in the water, some metals are essential to organisms. Talking...

The heavy metal pollution in the soil is one of the major threats to the environment due to its accumulative nature and non- biodegradability. Both natural such as geologic parent material, volcanic eruptions, wind - blown dusts in deserts and anthropogenic such as agricultural, mining, sewage water, industrial, transportation sources can be the reason of heavy metal pollution in environment...

Industries across the globe are major contributors of heavy metals. The amount of wastewater generated by domestic, industrial and commercial sources has increased in relation with the increasing population, urbanization, improved living standards of humans, and economic development. In many low income countries, both urban and non-urban areas of most developing countries depends, at least to a certain extent on...

Throughout time, our country has had many pollutants in our soil throughout time. Some are natural, but as we look closer to the industrial revolution, many are man-made. As this began, we realized many plants were not surviving near rivers and streams that were highly polluted, they also did not survive well near mines, because of the high amount of...

Large populations of humans tend to live near bodies of water. Because of these dense populations, water quality is an issue in these areas. Due to natural and anthropogenic changes, water quality can become poor (Duodu et. al). Contaminants negatively affect water quality from many sources such as disposal of liquid effluents, runoff carrying harmful chemicals that may be urban,...

“All substances are poisons; it is the dose that makes the poison.”, Philippus Aureolus Theophrastus Bombastus von Hohenheim stated. Heavy metals are commonly characterized as metals with a high toxicity level in high concentrations generally with high atomic numbers, atomic masses, or densities, and those metals are located on the 3rd-15th groups and through the 4th-6th periods. Moreover, heavy metals...

The concentration level of heavy metals (Pb, As, Cu and Fe) were assessed in five boreholes waters from Ikono Urban. Atomic Absorption Spectrometer was used to analyze the water samples. The results showed that Pb ranged from 0.15±0.040 - 0.40±0.094 mg/L; As, 0.05±0.008-0.10±0.041 mg/L; Cu, 0.02±0.008-0.06±0.016 mg/L and Fe, 0.20±0.016 - 0.37±0.025 mg/L. The concentration levels of Pb and As...

Introduction Coconut husk is a waste product in the coconut industry and has a capability of being an adsorbent in certain constituents. Surface runoff in metal rich soil are ignored as it is known to be a natural phenomenon that is costly and difficult if it is to overcome. Valuable metals could still be hoarded as natural adsorbents exist in...

Heavy metals can be defined as having high-density atomic weight or the atomic number, for example, heavy metals can be distinguished based on density. Some heavy metals are either essential nutrients usually Iron, cobalt, and zinc or relatively harmless such as ruthenium, silver, and indium. Other heavy metals like cadmium, mercury and lead which are considered highly toxic. Heavy metals...

Abstract Heavy metals beyond the threshold concentration in nature are often considered as phytotoxic. They cause damage to environment by affecting the soil fertility, biomass, crop yield and the human health. There are various approaches put forth by researches, but the most cost-efficient emerging remedy is been seen as phytoremediation; where the plants are itself involved partially or substantially in...

Abstract Contaminations by heavy metals in aquatic ecosystems strongly affect foodchain relationships through the process of biomagnification. Heavy metals (i.e. Fe, Cu, Mn, Pb, Zn, Cd, Cr, and Co) were determined from sediment, water and macrophytic species (Ceratophyllum demersum, Phragmites australis, and Potamogeton crispus) of Nigeen lake. The concentration of different heavy metals was determined using atomic absorption spectrophotometer. The...
