Bisphenol A concentration in canned fruits and vegetables and their risk assessment using Monte Carlo simulation in Iran.

Bisphenol A (BPA) is a chemical produced in large quantities for use primarily in the production of polycarbonate plastics, which has risks for human health. This study aimed to investigate BPA contents in canned fruit and vegetable samples using Gas Chromatography-Mass Spectrometry (GC-MS). Furthermore, health risks were assessed for Iranian adults and children using Monte Carlo simulations.

Determination of heavy metals, nitrate and nitrite in mineral and drinking bottled water in Tehran, Iran: A health risk assessment by Monte-Carlo simulation method.

Heavy metals, nitrate, and nitrite pose significant risks to public health and have raised substantial concern worldwide. This study aimed to investigate the content of nitrate, nitrite, and heavy metals, including Ba, Be, Ca, Fe, K, Li, Mg, Mn, Mo, and Na, in 30 bottled water brands in winter and summer in Tehran, Iran. Heavy metal contents in the samples were analyzed using Inductively Coupled Plasma Optical Emission Spectroscopy (ICP-OES), and nitrate and nitrite contents were analyzed using Ion Chromatography (IC).

Ponceau 4R elimination from fruit juice: An integrated optimization strategy utilizing artificial neural networks, least squares, and chitosan-nickel ferrite Nano Sorbent.

The goal of present work is to examine the efficiency of aminated-chitosan/NiFeO nanoparticles (AmCs/NiFeO NPs) produced for removing Ponceau 4R (P4R) from fruit juice through an adsorption process. The resulting nanoparticles were characterized using various techniques. The modeling of results was done using least squares (LS) and artificial neural network (RBF-ANN).

Application of nanomaterials for determination and removal of polycyclic aromatic hydrocarbons in food products: A review.

Polycyclic aromatic hydrocarbons (PAHs), toxic persistent pollutants, result in adverse impacts to human being health. Among the variety contaminant remediation approaches, nanotechnology was found promising in terms of its efficiency and exceptional size-dependent properties. Nanomaterials also possess high particular surface area, rapid dissolution characteristics, high sorption, magnetic -properties and quantum confinement.
