Apr 24, 2017· The objective of the study was to determine the heavy metal profile of some selected vegetables cultivated in Mubi North local government area of Adamawa state. Three replicate samples ofeach of the selected vegetables were randomly collected from the study area and analyzed for 5 heavy metals namely cadmium (Cd), copper (Cu),
The present study pertaining to monitoring of heavy metals like copper, zinc, iron, cobalt, cadmium, lead, chromium, selenium and arsenic accumulation in the given above selected ten deeper water ...
ABSTRACT The concentration of heavy metals such as Pd, Cd, Cu and Cr were studied using AAS on vegetable samples such as Tomato (fruit and leaf) and Onion bulb. Trace element as Cu showed high concentration. The concentration of heavy metal like Cu ranged from of 0.155 to 0.024mg/kg in tomato fruit; 0.120 to 0.057mg/kg in leafy tomato; 0.118 to 0.121mg/kg in onion bulb which were more than …
The Table 1 present the concentration of some selected heavy metals in liver and muscle of cow meat sold in Yenagoa metropolis, Bayelsa state, Nigeria. The concentration of chromium were <0.001 mg/kg in both liver and muscle of the cow meat. The concentration of chromium reported in this study is lower than the findings of other previous reports.
Keywords: Heavy metals, Vegetables, Tomatoes, Soil, Bioconcentration factor 1. Introduction Pollution of foods by heavy metals is a worldwide phenomenon. Studies have revealed that fruits and leafy vegetables are vulnerable to heavy metal contamination from soil, wastewater and air …
----- NOTICE This review of contaminants and remedial options at selected metal-contaminated sites summarizes Information collected from U.S. Environmental Protection Agency (EPA) programs, peer-reviewed journals, industry experts, vendor data, and other sources.
Selected heavy metals are used as catalysts in fuel processing (rhenium, for example), synthetic rubber and fibre production (bismuth), emission control devices (palladium), and in self-cleaning ovens (where cerium(IV) oxide in the walls of such ovens helps oxidise carbon-based cooking residues).
Conclusion: The concentrations of heavy metals at the roadside and residential area were higher than permissible limits set for medicinal plants, but the botanical garden was the lowest and safest in terms of heavy metals accumulation in the medicinal plants studied in the three locations.
Levels of Selected Heavy Metals in Some Nigerian Vegetables. Anthony E. Aiwonegbe and Esther U. Ikhuoria : ABSTRACT. Heavy metal content of twelve vegetable samples procured from local markets in Benin and Lagos cities is estimated by wet digestion and atomic absorption spectrophotometry. The metals include Fe, As, Pb, Hg, Cd, Cr, Zn and Ni.
Jun 04, 2019· Keywords Heavy metals · Natural radioactivity · Agricultural farmlands · Pearson correlation coefﬁcient · Dose rates 1 Introduction Heavy metals occur in the environment primarily as a result of natural processes such as weathering of thesource rock and atmospheric deposition.
Jun 10, 2019· The increased levels of these metals in soils may 402 CHUDE et al.: HEAVY METALS IN SELECTED SOILS lead to increased uptake by plants and animals as well as movement to ground and surface water 4. There are a lot of reports on the distribution of heavY metals in soils especially from industrialized countries.
The study determined heavy metal levels in selected tissues and organs of these animals to sensitize the people on the danger/safety of the consumption of their meat. A cross-sectional study design with laboratory analysis component was adopted. Atomic Absorption spectrometer, buck scientific 2010 model was used to assess the residual level of some heavy metals; Cd, Cr, Ni and Pb in the blood ...

chemicals, including heavy metals, in these products. Many cosmetic products contain heavy metals such as lead, cadmium, chromium, arsenic, mercury, cobalt, and nickel as ingredients or impurities. Recent research has reported that these metals can easily cause many types of skin problems (Nesterenko and Jones 1997; Sainio et al. 2000).
being analyzed for field parameters and heavy metal contaminant concentrations. Selected contaminant concentrations for Cd, Cr, Cu, Ni, Pb,and Zn were measured and their distribution within soils of the wetland basin studied. The results indicated that metal concentrations in the upper 10 cm of the
Each Party shall develop and maintain emission inventories for the heavy metals listed in annex I, for those Parties within the geographical scope of EMEP, using as a minimum the methodologies specified by the Steering Body of EMEP, and, for those Parties outside the geographical scope of EMEP, using as guidance the methodologies developed through the work plan of the Executive Body.
The results revealed that the selected medicinal plants accumulate these elements at different concentrations. Monitoring such medicinal plants for heavy metals concentration is of great importance for physicians, health planners, health care professionals, and policymakers in protecting the public from the adverse effects of these heavy metals.
