The geochemical distributions of cadmium (Cd), copper (Cu), chromium (Cr), lead (Pb) and zinc (Zn) were examined in sediments collected from Old Nakagawa River (NR), Tokyo, Japan. A widely used 5-step sequential extraction procedure was employed for the fractionation metals concentrations measured liquid extracts by inductively coupled plasma mass spectrometry (ICP-MS). association Cd (76-98%) Zn (48-67%) found highest with AEC (adsorbed/exchangeable/carbonate) phase, Cu (45-60%) Pb (44-73%)...

Abstract A study was undertaken to determine the contents of trace metals in 60 topsoils and 80 brinjal fruits samples from a famous brinjal-producing area Bangladesh using atomic absorption spectrophotometer. The also looked at soil pollution levels, dietary intake nutritionally important elements, human health risks toxic induced by dermal exposure consumption brinjal. content Pb, Ni, Cd, Cu, Fe, Mn, Zn harvested farmer′s fields ranged 0.204–0.729, 0.031–0.212, < 0.010–0.061,...

The concentrations of four heavy metals in rice grains and the health risk assessments were studied. Sixteen samples gathered from Rajshahi, Bangladesh. Average lead, chromium, manganese, cadmium measured 6.87, 0.43, 44.58, 1.13 mg/kg, respectively. concentration level found most is greater than acceptable limit as set by WHO. assessment was done using intended hazard ratio target carcinogenic where values for quotient 1. cancer-causing a maximum number are lower 10-4, which considered safe....

This study provides a geochemical partitioning and mobility pattern of Iron (Fe), Manganese (Mn), Cadmium (Cd), Copper (Cu), Chromium (Cr) Nickel (Ni) in sediment samples collected from Nomi River, Tokyo, Japan. For the particulating trace metals, widely used 5-step sequential extraction procedure was employed concentrations were measured liquid extracts by inductively coupled plasma mass spectrometry (ICP-MS) atomic absorption spectroscopy (AAS) to understand enrichment metal availability...

Environmental mobility and geochemical partitioning of iron (Fe), manganese (Mn), cobalt (Co), nickel (Ni) molybdenum (Mo) were examined in sediments collected from the whole old Nakagawa river (NR), Tokyo, Japan. A combined 6- step sequential extraction procedure was employed for metals concentrations measured liquid extracts by atomic absorption spectrophotometry (AAS) inductively coupled plasma mass spectrometry (ICP-MS). The observed order potential aquatic system NR was: Ni > Co Mo Mn...

Dietary exposure is the main source of bioaccumulation trace elements through contaminated fruits and vegetables, which are rich sources vitamins minerals, but also toxic elements, harm our health well-being. This study focused on human nutrition risks associated with cancer-causing non-cancerous in commonly available winter vegetables collected from Mymensingh divisional city markets. Six locally (viz. pineapple, guava, hog plum, water chestnut, banana, Indian olive) six seasonal red...

Disposal of urban and industrial waste is one the major problems responsible for both soil water pollution in Chittagong city, Bangladesh. Total 22 surface samples were collected from different locations city to assess quality metallic level. The concentrations Fe, Mn, Cu, Cr Pb ranged trace- 10.37, 1.91, 0.824–0.999, 0.11–1.32 1.69–2.56 µg ml -1 , respectively while contents Zn Ni trace. Among metals, was dominant followed by Cu Cr. study results inferred that all unsuitable irrigation due...

An experiment was conducted at the Department of Agricultural Chemistry, BAU to assess heavy metal status in different feed and fertilizer samples collected from Sadar Trisal upazilas Mymensingh district. The included poultry fish feeds, whereas, DAP, TSP, MOP, gypsum zinc sulphate (ZnSO4). AAS analysis Cd, Cr Pb showed variable levels contamination samples.

The Dhaka city, the capital of Bangladesh is one most densely populated cities in world. Tongi canal situated on north which connected Turag river to west and Balu east. A total 26 water samples were collected from measure irrigation quality basis their trace metal major ionic constituents. Trace metals concentrations determined using an Atomic Absorption Spectrophotometer. amount Fe, Mn, Zn Pb ranged 0.01-0.80, trace-1.02, trace-0.054 <TEX>$0.43-0.64{\mu}g\;mL^{-1}$</TEX>, respectively....

The study was conducted to determine heavy metal contents in industrial wastewater and contaminated soils of Bhaluka, Mymensingh assess their pollution level. A total 9 12 farm soil samples were collected directly from the farmers’ fields Bhaluka area analysed for this study.
