The average content of heavy metals in Weining soil of karst landforms is generally higher than that of other agricultural regions. The aim of this study was to evaluate the heavy metal content in potatoes from Weining county and to analyze the correlation between the content of heavy metals in potatoes planted in the soil of karst landform and the soil’s environmental factors (soil heavy metals, soil pH, soil organic matter, altitude). Weining county (Guizhou province, China) is a typical karst landform, and has a potato production yield of 2.7 million tons. In this study, 56 soil and potato samples were collected from Weining county and the heavy metal content in the soils and potatoes was detected by inductively coupled plasma atomic mass spectrometry (ICP-MS). The content of Cr, Ni, and As in the soil was found to be higher, with almost half of the samples exceeding the maximum allowable levels. A total of 9 of the 56 samples tested had pollution load index values greater than 1.0, which indicates serious soil pollution. It was found that the ability of the potato to absorb heavy metals from the soil was very low, with the average bio-concentration factors of the metals Zn, Cu, Pb, Cr, Ni, and As being 0.087, 0.088, 0.0028, 0.0034, 0.0066, and less than 0.001, respectively. The content of the six heavy metals in the potatoes were all lower than the maximum permissible limit. The results show that a high As content in the soil could increase the content of Pb in potatoes, that a lower pH was beneficial to the bioaccumulation of Cr and Ni in potatoes, and that a high altitude is detrimental to the bioaccumulation of zinc and copper in potatoes. The HRI ranged between 1.12 × 10−2 and 5.92 × 10−2.

Seven selected heavy metals namely Fe, Cu, Mn, Pb, Zn, Cd and Ni in five vegetable oils used in frying plantains (fresh and fried) collected from Ado-Ekiti, Ekiti State, were determined by graphite furnace atomic absorption spectrometry (GF-AAS) after microwave digestion. The accuracy of procedure was confirmed by certified reference materials (NIST). The relative standard deviations were found below 10%. In all the various oils (fresh and processed), the concentrations for Fe, Cu, Mn, Pb, Zn, Cd and Ni were observed in the range of 0.0005 -0.0018, 0.0002 – 0.0009, 0.0004 – 0.0021, 0.0001- 0.0007, 0.0003 – 0.0016, 0.0001 – 0.006 and 0.0002-0.0010 mg/kg, respectively. In general, among all the oils, fresh palm oil (FPO had the highest concentration) for all the selected heavy metals. Comparing with safety intake levels for these heavy metals recommended by Institute of Medicine of the National Academies (IOM), US Environmental Protection Agency (USEPA) and Joint FAO/WHO Expert Committee on Food Additives (JECFA), the dietary intakes of the seven heavy metals from daily consumption of edible vegetable oils for a 70 kg (adult) and 24 kg (children) body weight should pose no significant health risk to consumers. However, for adults and children, the THQ and HI were low. The TCR values also indicate low to moderate carcinogenic risks for adults and children.

“…The potential risk of OCPs and 16EPA PAHs should be studied and evaluated to ensure consumer protection. Therefore, several studies in different countries have reported the human health risk assessments of OCPs and PAHs in different types of foods (Karthik and Vijayarekha, 2018;Lee et al, 2019). To the best of our knowledge, however, there are no studies evaluating OCP and 16EPA PAH levels in Jordanian olive oils, and no data on the potential health risks of these compounds in olive oils have been reported.…”

Many organochlorine pesticides (OCPs) and polycyclic aromatic hydrocarbons (PAHs) pose risks to human health; so, their levels in foods should be constantly monitored. In the present work, the potential health risks of 21 OCPs residues and 16 carcinogenic PAHs in Jordanian olive oil were evaluated. A total of 27 olive oil samples were obtained from nine olive mills in Jordan. The levels of PAHs and OCPs were evaluated by gas chromatography coupled with mass spectrometry detector. Among the studied pesticides, only 4,4-Dichlorodiphenyldichloroethylen (4,4-DDE) was found in the tested samples. The estimated average dietary intake (EADI) and hazard risk index (HRI) were then assessed for the 4,4-DDE. The estimated HRI value of 4,4-DDE was less than 1, thus indicating no health risk to consumers. Regarding PAHs, the average concentration of 16 PAHs in the tested olive oil was 36.5 µg/kg. Health risks due to PAH contamination were estimated by determining the dietary daily intake (DDI) and toxic equivalent quotient (TEQ). The values ranged from 0.139 × 10-2 to 7.70 × 10-2 and 0.01 to 0.57 µg/kg for DDI and TEQ, respectively. Light PAHs were predominant in the samples, while no heavy PAHs were detected. The incremental lifetime cancer risk (ILCR) was estimated, and the values ranged from 0.1 × 10-7 to 5.62 × 10-7, and none of the olive oil samples exceeded the limit value of 10-6, thus indicating insignificant potential risk.
