The goal of this research was to assess the phthalic acid esters (DEP, DMP, BBP, DBP, DEHP, DnOP and total PAE) in non-alcoholic malt beverages bottled were magnetized with iron (MWCNT-Fe3O4) using Mass spectrometry is gas chromatography (GC-MS) in Tehran. The results showed that maximum and minimum of total phthalate esters in samples were 9483.93 and 2412.50 ng/l, respectively. The mean of DEHP (which has also been found to be carcinogenic) in all samples was lower than 5944.73 ng/l. The maximum concentration of DEHP in four samples was upper than 8957.87 ng/l. Multivariate techniques and heat-map visualization were used to assess the correlation among the type and levels of PAEs with brand, color, product date, pH, sugar, volume and gas pressure. Therefore, based on heat-map and principal component analysis (PCA) results, the Bis (2-ethyl hexyl) phthalate (DEHP) and total PAEs were the closest accessions, indicating that these variables had similar trends. Based on the results, it can be stated that due to the low average of total phthalate esters in non-alcoholic malt beverages, there is no serious health hazard of these compounds for humans.

The current study aims to investigate the levels of the toxic metal in agricultural products (legumes, wheat, and potato) collected in Markazi province, Iran, and human health risk by using inductively coupled plasma - optical emission spectrometry (ICP-OES). The levels of arsenic (As) and cadmium (Cd) in all samples were lower than the limit of detection (LOD), while the level of Cd in potato samples was lower than the maximum permisible level (MPL) of the European commission (EC). The non-carcinogenic and carcinogenic risk assessment by direct ingestion of agricultural products was calculated using the United States Environmental Protection Agency (USEPA) method. The highest mean of toxic metals was observed for lead (Pb) in legume samples (562.17 μg kg− 1). Mercury (Hg) and Pb levels in all samples were higher than LOD, while Pb level in wheat samples were lower than of EC. The rank order of Hg and Pb levels in all samples based on target hazard quotient (THQ) value was wheat> potato>legume. The THQ index of Hg and Pb by the deterministic method in wheat was 1.37 and 0.454; in potato 0.139 and 0.104; in legume 0.092 and 0.41, respectively. The carcinogenic risk index was at an acceptable range. The high hazard index values were estimated and the THQ index for Hg in wheat suggests a non-negligible health risk.
