Industrial processes and used commercial (metallic) products generate a large amount of metallic waste, which is discharged into the environment via water or land-dumping sites. It is estimated that the toxicity of metallic discharge into the environment far outweighs the total toxicity of all radioactive and organic wastes combined. The importance of metals and their compounds in industrial operations cannot be overstated. Meanwhile, industrial effluents contain heavy metal ions that have been reported to be harmful to human and plant … Continue reading “Studies on Removal of Toxic Cd2+ and Pb2+ from Aqueous Solutions by Using Agro-waste (Cola nitida Pod)”

Some Heavy Metals Speciation and Bioavailability in Agricultural Soils Used for Cultivating Various Vegetables

Vegetables grown in polluted soils with unregulated agrochemical applications may contain heavy metals. Because farmers used too many agrochemicals, this could happen in vegetables grown in Bedugul’s agricultural soils. To consider metals transfer to vegetables, a speciation and bioavailability approach had to be studied. The purpose of this research was to determine the speciation and bioavailability of certain heavy metals in agricultural soils in Bedugul, Bali. used to cultivate a wide range of vegetables The sample was subjected to wet … Continue reading “Some Heavy Metals Speciation and Bioavailability in Agricultural Soils Used for Cultivating Various Vegetables”

Assessment of Atmospheric Metal Pollution Biomonitoring Potential by Neem Tree (Azadirachta indica) Leaves in Katsina Metropolitan Area of Katsina State, Nigeria

Trace metal concentrations in plants and animals have been used as an indicator of environmental monitoring. Heavy metals from the soil primarily enter plants through the root system. In general, plant roots are the most important site for chemical uptake from soil. The leaves of the neem tree (Azadirachta indica) were used as a bio-indicator in this study to track trace metal levels in Katsina. Leaves were collected from four locations in Katsina metropolis: Site A, Site B, Site C, … Continue reading “Assessment of Atmospheric Metal Pollution Biomonitoring Potential by Neem Tree (Azadirachta indica) Leaves in Katsina Metropolitan Area of Katsina State, Nigeria”

Modeling of Heavy Metal (Ni, Mn, Co, Zn, Cu, Pb, and Fe) and PAH Content in Stormwater Sediments Based on Weather and Physico-Geographical Characteristics of the Catchment: An Advance Data-Mining Approach

The processes that determine the quality of sediment in drainage systems are dynamic and complicated. However, because these topics have not been widely examined in research studies, there is relatively little information available on the effects of both watershed characteristics and meteorological circumstances on sediment chemical properties. The amount of selected heavy metals (Ni, Mn, Co, Zn, Cu, Pb, and Fe) and polycyclic aromatic hydrocarbons (PAHs) in sediments from the stormwater drainage systems of four catchments in the city of … Continue reading “Modeling of Heavy Metal (Ni, Mn, Co, Zn, Cu, Pb, and Fe) and PAH Content in Stormwater Sediments Based on Weather and Physico-Geographical Characteristics of the Catchment: An Advance Data-Mining Approach”
