Data on concentrations of polycyclic aromatic hydrocarbons (PAHs) in roasted and fried chicken - A case study: Bushehr, Iran

Global review, meta-analysis and health risk assessment of Polycyclic Aromatic Hydrocarbons (PAHs) in chicken kebab using Monte Carlo simulation method

The primary concern with Polycyclic Aromatic Hydrocarbons (PAHs) is their harmful effects on health, including the risk of causing cancer. This study aimed to investigate the occurrence and concentration of 16 priority PAHs (PAH16) in chicken kebabs using a systematic review approach with meta-analysis. Additionally, the study estimated the possible risk assessment of the potential carcinogenic and non-carcinogenic effects of PAHs on consumers of chicken kebabs using the Monte Carlo simulation (MCS) method. The researchers collected data on the concentration of PAHs in chicken kebabs (grilled, smoked, roasted, or barbecued) from 99 original articles searched in the Web of Science, PubMed, Scopus, Science Direct, and Google Scholar databases from 2012 to April 2022. The concentration of PAHs was then analyzed using meta-analysis, and the Monte Carlo simulation (MCS) was used to evaluate the associated human health risks. The analysis showed that 68.6%, 21.1%, 7.1%, and 3.2% of chicken kebabs were prepared by grilling, smoking, barbecuing, and roasting, respectively. The meta-analysis and health risk assessment indicated that the mean values of HQ (hazard quotient) in Bap, Ace, Acy, Pyr, Flt, Flr, Nap, and Ant PAHs were 1.64, 1.38 × 10^-2, 1.10 × 10^-1, 1.09 × 10^-1, 2.55 × 10^-2, 1.60 × 10^-1, 8.13 × 10^-1, and 6.20 × 10^-3, respectively. Additionally, the mean values of LTCR (Incremental Lifetime Cancer Risk) in Bap, Ace, Acy, Pyr, Flt, Flr, Nap, and Ant were 4.85 × 10^-10, 8.06 × 10^-13, 6.65 × 10^-12, 3.23 × 10^-12, 1.01 × 10^-12, 6.38 × 10^-12, 1.62 × 10^-11, and 6.20 × 10^-3, respectively. The consumption of chicken kebabs prepared by barbecuing was found to be associated with an increased risk of cancer due to the formation of carcinogenic compounds, including benzo[a]pyrene (BaP). However, the non-cancer risk ratio of consuming grilled chicken other than BaP was found to be less than 1 (HQ < 1), indicating that there is no risk of carcinogenesis caused by PAHs from the consumption of chicken kebabs worldwide. The calculated values of the LTCR caused by PAHs in the consumption of chicken kebab throughout life were compared to the maximum acceptable risk value suggested by the EPA, which in the strictest case equals one cancer case per 10,000 people. The results indicate that there is no risk of carcinogenesis caused by PAHs due to the consumption of chicken kebab worldwide.

Occurrence of polycyclic aromatic hydrocarbons in fried and grilled fish from Shandong China and health risk assessment

Diet is the main way for the human body to ingest polycyclic aromatic hydrocarbons (PAHs). In this study, the occurrence, dietary exposure, and health risks of 15 PAHs in 31 fried and grilled fish samples were investigated, which were collected from the Shandong Province of China. The results showed that benzo[a]pyrene (BaP) of 5 samples exceeded the European Union (EU) limit value. Naphthalene (NaP) and fluorene (Fle) were present in all samples, and the average concentration of ∑15PAHs was 91.1 μg/kg, with light PAHs dominated. The average contamination level of ∑15PAHs in fried and grilled fish was distributed differently, and there seemed to be more PAH contamination in the grilled samples. The results of the margin of exposure (MOE) suggested that PAH ingestion through fried and grilled fish did not imply significant toxicological concern for consumers in Shandong. The incremental lifetime cancer risk (ILCR) values for the consumption of fried and grilled fish were higher than 1 × 10-6, indicating a potential health risk in the adult population. The study provides baseline health information on PAH intake by residents due to dietary exposure to fried and grilled fish food products, suggesting that health risk monitoring of PAHs in such foods should be continually performed.

The concentration of polycyclic aromatic hydrocarbons (PAHs) in the processed meat samples collected from Iran's market: a probabilistic health risk assessment study

The concentration of PAHs among raw and cooked meat products (sausages and burgers), randomly collected from five regions of Tehran, Iran, was investigated by the aid of a gas chromatography-mass spectrometry (GC-MS), and the risk assessment was conducted. The concentration of 16 types of PAHs in sausage and burger samples was found in the range of 8.08 to 29.55 and 10.18 to 29.85 μg/kg, respectively. The concentrations of some PAHs such as anthracene (A) (14.12 μg/kg) and acenaphthylene (Acl) (13.4 μg/kg) were higher than the European Standard (2 μg/kg). Among the meat products with different meat percentages (50, 70, and 90), the highest level of total PAHs was noted in the product containing 90% meat (19.34 μg/kg), while the highest mean level of PAHs was noted in fried meat products (23.31 μg/kg). A positive and significant correlation between cooking method and brand of product with the concentration of PAHs (p-value < 0.05) was noted. Also, no concern regarding the non-carcinogenic risk due to the ingestion of PAHs via consumption of the meat products was demonstrated by the health risk. However, the carcinogenic risk due to the consumption of sausage and burger was at the tolerable (1E-6 to 1E-4) and considerable (> 1E-4) risk levels, respectively. In this regard, further assessments to control and modify the cooking method among the Iranian population were recommended.
