This study assessed the level of some selected heavy metals in cassava mill effluents contaminated soil from Ndemili community in the Niger Delta region of Nigeria. Triplicate soil samples were collected using soil augar at 0 20 cm depth from 6 locations including one control. Sampling was carried out bimonthly (from November 2016 to September 2017) covering the two predominant seasons wet and ...

In this work studies on rapid inhibitory interactions between heavy metals and photosynthetic materials at different organization levels were carried out by optical assay techniques, investigating the possibility of applications in the heavy metal detection field. Spinach chloroplasts, thylakoids and Photosystem II proteins were employed as biotools in combination with colorimetric assays based...

Background & Aims of the Study: Aquatic macrophytes, given their rapid growth and high bio mass production, great potential to accumulate heavy metals in their organs. Phragmites australis as a hyper-cumulative plant plays an important role in the bioremediation. The Badavar River of Noorabad, Lorestan province, is exposed to urban wastewater and agricultural runoffs. In order to heavy metals (...

Heavy metals are dangerous because they tend to accumulate. Compounds accumulate in living things any time they are taken up and stored faster than they are broken down or extracted (metabolized). Heavy metals can enter the water supply by industrial or consumer waste or even from acidic rain breaking down soils and releasing heavy metals into streams, lakes, rivers and ground waters [1]. Altho...

The development of Missouri's new lead belt within the past decase has provided an excellent opportunity to study the dissemination and effects of heavy metals in a deciduous forest ecosystem. Primary lead smelters within the new lead belt have been identified as potential sources of cadmium as well as lead, zinc, and copper. Sintering and blast furnace operations tend to produce significant qu...

Background and purpose: There is an increasing interest towards consumption of aquatic products, therefore, the health of aqua ecosystems is highly important. Heavy metal pollution in fish is a global concern due to its bioaccumulation potential, toxicity and persistence in food chain. This study investigated the concentration of heavy metals (cadmium, lead, chromium, copper, and zinc) in the g...

to determine the extent and the size of the environment pollution with heavy metals, biologicalmethods, investigating the enzymatic activity of soil can be applied. most frequently, the enzymes investigated in the soils threatened with anthropogenic contamination are phosphatases, dehydrogenases as reacting fastest to the increase in the content of heavy metals in the environment. the aim of th...

Heavy metals i.e. Copper (Cu), Zinc (Zn), Manganese (Mn), Iron (Fe), Cadmium (Cd), Nickel (Ni), Mercury (Hg) and Arsenic (As) were analyzed in 35 samples of the fish muscle, from East Kolkata Wetlands (EKW). The concentration of heavy metals was in order of, Fe > Zn > Cu > Mn > Ni > As > Hg > Cd. The essential metals, such as iron, zinc, copper and manganese were in higher concentrations and, t...

Introduction: Heavy metals like Cadmium, Arsenic, Lead and Mercury are regarded as the most common heavy metals in the environment which can enter the food chain via various routs and may cause a great number of disorders within humans. Besides these heavy metals, such metals as Zinc and Copper can be dangerous in excess amounts. Edible salt, as one of the main additives, can contain these heav...
