Bioaccumulation of Organophosphorus (OPs) and Carbamate (CBs) Residues in Cultured Pangas Catfish () and Health Risk Assessment.

In the present study, the presence of organophosphorus (OPs) and carbamates (CBs) residues in the pond water and cultured Pangas catfish () samples collected from Comilla and Mymensingh areas were detected and assessed for their potential health risks. A total of 100 samples from each category were analysed among which 17% of the pond water samples and 9% of the fish samples were detected contaminated with OP and CB residues. The pond water and fish samples were extracted by liquid-liquid extraction (LLE), quick, easy, cheap, effective, rugged, and safe (QuEChERS) extraction, and ultrasonic extraction, respectively, and analysed through gas chromatography tandem mass spectrometry (GC-MS/MS).

Detection of acrylamide traces in some commonly consumed heat-treated carbohydrate-rich foods by GC-MS/MS in Bangladesh.

The present study aimed to determine acrylamide traces in180 heat-treated carbohydrate-rich foods through gas chromatography coupled to mass spectrometry (GC-MS/MS) in Bangladesh. Detected acrylamide contents were 730 ± 293 μg/kg, 244 ± 83 μg μg/kg, 598 ± 222 μg/kg, 340 ± 189 μg/kg, 548 ± 278 μg/kg, 217 ± 77 μg/kg, 558 ± 297 μg/kg, 391 ± 263 μg/kg and 679 ± 285 μg/kg in potato chips, chanachur (a locally processed food), potato crisps, biscuits, cake, bread, crackers, breakfast cereals and French fries respectively. The use of different ingredients during the manufacturing process might affect on acrylamide formation as different ingredients contained variable amounts of free asparagines and reducing sugars to form acrylamide.

Accumulation of Heavy Metals in Rice (. L) Grains Cultivated in Three Major Industrial Areas of Bangladesh.

Human exposure to nonessential trace elements occurs from food crops that are contaminated by the soil. The present study aimed to determine the level of heavy metals in soil and rice samples using an atomic absorption spectrophotometer from three major industrial areas in Bangladesh: Savar, Gazipur, and Ashulia. Heavy metals were detected in the order Fe > Zn > Ni > Cr > Pb > Co > Cu > Cd > As and Zn > Cu > Cr > Co > Fe > Cd > Pb > Ni > As in the soil and rice samples, respectively.
