Abstract
Nickel (Ni) is a widespread metal that occurs in food and drinking water from both natural and anthropogenic sources. Oral exposure to Ni can induce a variety of adverse effects; the European Food Safety Authority established a tolerable daily intake (TDI) of 13 μg/kg bw and a lowest-observed-adverse-effect level (LOAEL) of 4.3 μg/kg bw to assess the risk of allergic reactions upon acute exposure. This study, the first conducted in Armenia, aimed to assess the dietary exposure of the adult Yerevan population (1272 subjects of both sexes) to Ni in a total diet study (TDS). Detection of Ni was carried out using atomic absorption spectrometry. To determine food consumption values, a 24-h recall survey was used. Following the K-means clustering test, two clusters were determined for food product intake. For the risk characterization of acute oral exposure, the margin of exposure (MOE) was calculated using both deterministic and probabilistic (Monte Carlo method) approaches. The average total exposure was 4.396 μg/kg bw, with limited influence by age and gender. The main contributors were "fruits and vegetables" followed by "bread and flour-based products": the total intake would be 5.11 μg/kg bw for a woman with high consumption of fruits and vegetables. Hence, the estimated chronic dietary exposure was below the TDI, irrespective of age and gender groups, and including high consumers. However, acute oral exposure estimates led to MOE values of less than 30 for most food products, indicating potential health concerns for Ni-sensitized individuals. The Monte Carlo approach indicated that the probability of occurrence of MOE lower than 30 was very high in the case of beef/veal, pork and chicken meat, eggs, and fish, alongside vegetable sources such as buckwheat, tomato, watermelon/melon, and potatoes. The findings prompt an investigation of Ni sources in the target foods in the Caucasus area.

Crosscutting of the pollutants and building ventilation systems: a literature review. ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2023; 30:66538-66558. [PMID: 37121949 PMCID: PMC10149636 DOI: 10.1007/s11356-023-27148-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 07/11/2022] [Accepted: 04/17/2023] [Indexed: 05/04/2023]
Abstract
Considering the time spent in enclosed environments, it is essential to study the relationship between pollutants and building ventilation systems to find whether the types and levels of pollutants and greenhouse gasses, which are expected to be exhaled through ventilation systems into the atmosphere, have been adequately evaluated. We propose the hypothesis that the exhaled air from residential buildings contains pollutants that may become another source of contamination affecting urban air quality and potentially contributing to climate drivers. Thus, the main goal of this article is to present a cross-review of the identification of pollutants expected to be exhaled through ventilation systems in residential buildings. This approach has created the concept of "exhalation of buildings" a new concept enclosed within the research project in which this article is included. We analyze the studies related to the most significant pollutants found in buildings and the studies about the relation of buildings' ventilation systems with such pollutants. Our results show that, on the one hand, the increase in the use of mechanical ventilation systems in residential buildings has been demonstrated to enhance the ventilation rate and generally improve the indoor air quality conditions. But no knowledge could be extracted about the corresponding environmental cost of this improvement, as no systematic data were found about the total mass of contaminants exhaled by those ventilation systems. At the same time, no projects were found that showed a quantitative study on exhalation from buildings, contrary to the existence of studies on pollutants in indoor air.
