“…In recent years, researchers started to put emphasis on the impacts of coal trace elements on human health (Dai, 2012;Swaine, 2000). Meanwhile, numerous analytical approaches and models have been developed and implemented to address the assessed risks of coal organic and inorganic pollutants (Yu et al, 2014). Peña-Fernández et al (2014) established a model for the assessment of human health risks of metals and metalloids in urban environments, and the finding was that the content of contaminants in soils, such as arsenic or chromium, has exceeded the safe level for public.…”

ABSTRACT:On the basis of a pilot study, the present study established an efficient method for the assessment of human health risks caused by some harmful trace elements (e.g., arsenic, beryllium, mercury and fluorine) in coal gasification residues. The proposed assessment procedure was divided into five basic steps, namely, hazard identification, exposure assessment, toxicological evaluation, risk characterization and control value calculation. The results showed that the carcinogenic risks within sensitive areas could reach 2.31 × 10 -4 and the total non-carcinogenic hazard quotient of these four harmful trace elements within sensitive areas was 12.13, which is much higher than the referencing risk level as 10 -6 for carcinogenic risk and 1 for non-carcinogenic. In terms of risk management, it could be suggested that the concentration of Arsenic should be controlled under 7.29 mg·kg -1 within sensitive areas, meanwhile under 1.59 × 10 -4 mg·kg -1 within insensitive areas.

“…RQ less than unity indicates that the chemical involved is less likely to pose a significant health risk to the consumers. RQ greater than unity would indicate that exposure concentration exceeds RfD and a more refined risk assessment is needed to ascertain whether appropriate control or management measures are required (13,25). The likelihood of risk is related to the degree to which exposure exceeds the RfD.…”

“…The RfD is an estimate, with an uncertainty of perhaps an order of magnitude, of a daily exposure that is likely to be without appreciable risk of deleterious health effects in the human population (including sensitive subgroups) over a lifetime (13,18).…”

“…RQ is defined as the ratio of daily fish exposure level (EDI) in relation to reference dose (RfD) considering non-carcinogenic effects of the contaminants. The RQ was calculated as follows (13,18):…”

“…Dietary intake is an important route of human exposure to organochlorine compounds (11,12). Several studies have investigated the dietary exposure and assessed the risk of POPs for the general population through the consumption of food in various countries (11,13,14,15). Therefore, risk assessment of the POPs in seafood is important and necessary to manage risks from seafood intake (16,17).…”

PURPOSE: The objective of this study was to estimate the dietary intake (EDI) of organochlorine pesticides (DDT and its metabolite) through consumption of fish in Bulgaria. The potential health risk was assessed based on the dietary intake of DDTs through fish consumption. METHODS: DDT and its two main metabolites DDE and DDD were determined in muscle tissue of six fish species widely consumed by the population of Bulgaria: goby (Neogobius melanostomus), sprat (Sprattus sprattus), grey mullet (Mugil cephalus), horse mackerel (Trachurus Mediterraneus ponticus), shad (Alosa pontica pontica) and bluefish (Pomatomus saltatrix). Samples were collected from Black Sea coast of Bulgaria during 2007 -2011. The DDT and its metabolites were determined by capillary gas chromatography system with mass spectrometry detection. RESULTS: The levels of the Total DDTs (sum of DDT, DDE and DDD) ranged from 18.5±8.3 to 200.2±41.9 ng/g wet weight (in goby and shad, respectively). The mean EDI of DDTs in fish from Black Sea was calculated between 3.5±1.6 and 37.8±7.9 ng/kg body weight/ day through consumption of goby and shad, respectively. The health risk was assessed using a risk quotient (RQ) of the fish consumption as the ratio of daily fish exposure level (EDI) in relation to oral reference dose. CONCLUSIONS: The estimated dietary intake of DDTs through marine fish for the Bulgarian consumer does not pose a health risk.

State‐of‐the‐art applications of computational fluid dynamics (CFD) in the analysis and optimization of electrochemical reactors and redox flow batteries are reviewed. Various factors are covered which affect the efficiency of electrochemical reactors and redox flow batteries created using CFD simulation approaches, including physical and chemical factors, such as pH, treatment time, temperature, and the conductivity of the solution, as well as design elements like inter‐electrode distance and electrode materials. Different hydrodynamic variables are discussed that impact the efficiency of these systems, such as pressure distribution, velocity, tracer mass fraction, geometry, flow‐based electrochemical energy storage, and residence time distribution. Although CFD methods are reliable, more straightforward, and cost‐effective, also the limitations of CFD and the challenges are considered that remain in its development and application in electrochemical engineering. The significant progress made in the use of CFD to study electrochemical reactors and redox flow batteries and the technology's potential to improve the efficiency and sustainability of these technologies are emphasized.
