The interest in parasitic and chemical foodborne diseases has increased due to its increased danger, as chemical poisoning of food often occurs within minutes. This pollution occurs in restaurants or when preparing food at home, in food laboratories and in factories that produce food and drink in large quantities. In developing countries, intestinal parasites are one of the dangerous problems that affect health and lead to an increase in illness and death because of poor economic, social, and health conditions. Chemical hazards are both natural and unnatural toxins and contaminants in food. Some toxins come from the food source, either naturally or due to mishandling. Safe food provides health to the individual and the community and protects it from the risks of diseases that may cause by eating these contaminated foods. This review aims to report information and published data of foodborne diseases acquired in Sudan. The review showed that, there are many risks, to varying degrees, in a wide range of food consumed in Sudan, which raises concern about the potential threat to the public health of the people and requires more attention by the responsible authorities in the state such as the Sudanese Standards and Metrology Organization and the judicial authorities to establish laws that regulate and follow up on this.

“…The measurements were then used to assess health risk potentials following the consumption of heavy metals-contaminated fish. The results of this study can be used for the early warnings of the marine ecosystem pollution caused these three heavy metals, or as an ideal indicator in the assessment of current marine environmental pollution [ 24 , 25 ].…”

Background and Aim: Yellowfin tuna and swordfish are seafood commodities commonly caught from deep oceans worldwide. Therefore, this study aimed to assess the levels of three heavy metals, namely, cadmium (Cd), lead (Pb), and mercury (Hg) in yellowfin tuna and swordfish. The results are expected to provide consumers with information on the safety of consuming or exporting these fishes caught in the Hindian and Pacific Oceans. Materials and Methods: Fresh yellowfin and swordfish were obtained from fishermen’s catches in FAO Fishing Zone 57 (Indian Ocean) and 71 (Pacific Ocean) and then collected at Benoa Harbor, Bali Province. The comparative method was to evaluate the levels of heavy metals in each fish. Furthermore, heavy metal concentrations, including Pb, Cd, and Hg, were determined using atomic absorption spectroscopy analysis. These results were then used to assess the safety of these fishes by calculating the estimated daily intake (EDI) and target hazard quotients-total target hazard quotients (THQs-TTHQs). Results: The analysis showed that none of the samples exceeded the threshold levels for the three heavy metals, which was specified by the Indonesian National Standard (SNI) and European Commission Regulation (CR) No. 1881/2006. The EDI and provisional tolerable weekly index (PTWI) obtained in this study were still in the safe range. However, the PTWI values for Pb in yellowfin tuna product from the Indian Ocean were higher (0.0038 mg/kg) compared to the recommended standard for the adult population. The THQ-TTHQ values of fish caught from these oceans were also within the acceptable range specified by the two agencies, indicating that they are safe for consumption by people with various age groups and for export purposes. Conclusion: The average levels of three heavy metals (Cd, Pb, and Hg) in muscle samples of yellowfin tuna and swordfish caught from the Pacific and Hindian Oceans were within the acceptable range as specified by the SNI and CR No. 1881/2006. Furthermore, the EDI and THQs values indicated that fishes caught from the Pacific and Hindian Oceans were safe for consumption. This research is still limited to assessing two capture fisheries commodities. Further research is needed on the assessment of heavy metal levels in other capture fisheries commodities in this capture zone. Keywords: health risk assessment, heavy metal pollution, seafood products, Tuna.

“…Particulate matter deposited on the lung surface can lead to tissue damage and lung inflammation (Wei and Tang 2018 ; Losacco and Perillo 2018 ; Happo 2009 ). SO 2 is one of the five main pollutants that together account for more than 90% of air pollution in the world (Sharma 2001 ). Sulfur oxides in combination with particulate matter and moisture (e.g.…”

This paper presents a time-series analysis of SO 2 air concentration and the effects of particulates (either PM 2.5 and PM 10 ) concentrations and meteorological conditions (relative humidity and wind speed) on SO 2 trend in Tehran for the period from 2011 to 2020. The source data were obtained from 21 monitoring stations of Air Quality Control Company and meteorological stations in Tehran. To predict the status of future concentration of SO 2 , PM 2.5 and PM 10 , a Box–Jenkins ARIMA approach was used to model the monthly time series. Considering the whole period of ten years, a somewhat downward trend was noted for SO 2 air concentration, even though a slight rising trend was observed in 2020 year. Monthly sulfur dioxide concentrations showed the lowest value in June and the highest value in January. Seasonal concentrations were lowest in spring and highest in winter. Then, in the ArcGIS software, the IDW method was used to obtain air pollution zoning maps. As a result, the highest average concentration of SO 2 occurred in the north and southwest of Tehran. In the last step, Relations between the SO 2 concentration and particulate matters and relative humidity and wind speed were calculated statistically using the daily average data. We finally concluded that the combined effect of particulate matters and relative humidity with the increasing role of Sulfur dioxide overcomes the decreasing role of wind speed. This study can contribute to a better understanding of the SO 2 air pollution in Tehran affected by meteorological conditions and the rapid urbanization and industrialization, followed by the possible combustion of fuel oil in power plants and health problems.
