This study is aimed to assess the heavy metals contamination and health risk in Shrimp (Macrobrachium rosenbergii and Penaeus monodon) collected from Khulna-Satkhira region in Bangladesh. The results showed that the Pb concentrations (0.52-1.16 mg/kg) in all shrimp samples of farms were higher than the recommended limit. The Cd levels (0.05-0.13 mg/kg) in all samples and Cr levels in all farms ...
Kadmium (Cd) merupakan logam berat berbahaya yang dapat mengakibatkan terjadinya pencemaran di perairan. Penelitian ini bertujuan untuk mengetahui kandungan Cd pada matriks air, sedimen, dan ikan nilem (O. hasselti) Sungai Tajum, Banyumas serta tingkat berdasarkan Single Pollution Index (Pi), Contamination Factor (CF), of Geoaccumulation (Igeo), Bioaccumulation (BAF), Estimated Daily Intake (ED...
Pollution evaluation and health risk assessment are critical procedures for residents consuming black carp (Mylopharyngodon piceus) contaminated with non-essential hazardous trace elements in an artificial wetland also known as aquaculture pond. Samples were collected, dissected digested to analyze the pollution status associated four heavy metals present eleven tissues of fish based on metal i...
زمینه و هدف: طی سال های اخیر فعالیت های طبیعی و انسانی توانسته میزان زیادی آلاینده های فلزی را وارد اکوسیستم های آبی نماید. این آلاینده ها قادرند که در طول زنجیره غذایی بصورت تجمعی افزایش پیدا کنند. تحقیق حاضر به بررسی میزان فلزات نیکل، روی و وانادیوم در بافت عضله ماهی های آلوزا و سوف در جنوب شرقی دریای مازندران به دلیل اهمیت آنها پرداخته است. روش بررسی: پس از زیست سنجی، نمونه های ماهی...
In this study, pangas and feed samples were analyzed to estimate the levels of metallic elements profile human health risks due consumption contaminated fish. This investigation confirmed significant variations in heavy metal concentrations among different tissues order Ni > Cu Pb Cd Cr pre-monsoon = post-monsoon. Considerably higher Pb, Cu, estimated liver; detected muscle than other organs (p...
Background: Consumers may be contaminated by various food intakes as one of the most important sources of organic and inorganic pollutants associated with agriculture. The aim of this study was to evaluate the lead (Pb), cadmium (Cd) and nitrate contaminations in watermelon and carrot samples and the associated risks to human health. Methods: In this cross sectional study, 108 samples of wat...
Introduction: In recent years, the contamination of food with heavy metals has received much attention. Plants can absorb metal pollutants through contaminated water, soil, and air. Materials and Methods: In the current study, accumulation of minerals in three types of soybeans was investigated by wet and dry digestion methods using ICP-OES technique. Thereafter, the metals' health risk was as...
The effects of culinary practices such as boiling, frying, and grilling on the proximate compositions and concentrations of metals (Cd, Pb, Cr, Zn, Fe, Cu, Mn, Ni, and Hg) in commonly consumed fish species from the Nigerian coastal waters were investigated. The selected fish species were Polydactylus quadratifilis, Chrysicthys nigrodigitatus and Cynoglossus senegalensis. The culinary practices ...
Heavy metals are known to cause deleterious effects on human health through food chain. Human health risks were evaluated from consumption of heavy metal contaminated fish from Buriganga River in Bangladesh. Whole body of five fish species (Puntius ticto, Puntius sophore, Puntius chola, Labeo rohita and Glossogobius giuris) were analyzed which contained various concentrations of Cd, As, Pb, Cr,...
برای اغلب افراد، رژیم غذایی مسیر اصلی قرار گرفتن در معرض فلزات است، بهطوری که خطر ارزیابی این عناصر برای انسان از طریق مصرف رژیم غذایی مهم است. برای این منظور، در سال 1391 غلظت فلزات سرب و کادمیوم در عضله دو گونه ماهی کفال طلایی (Liza auratus) و کفال پوزه باریک (Liza Saliens) جمعآوری شده از خلیج گرگان اندازهگیری شد. برای اندازهگیری میزان فلزات سرب و کادمیوم در تمامی نمونهها از دستگاه جذب ا...
