Introduction: The present study investigated one of these types of disease (skin cancer) and its relationship with climatic parameters. The aim of this study was to investigate the relationship between climate change and skin cancer in Ardabil province. Materials and Methods: This descriptive correlational study was conducted to investigate the effect of six climatic parameters (frost, sunny hours, minimum mean humidity, maximum absolute temperature, minimum absolute temperature, and mean temperature) on skin cancer in Ardabil province in a 3-year statistical period (2012-2014). The data were analyzed using the Spearman correlation relationship in SPSS version 24 software, also Minitab version 16 software was used for linear interpolation. Results: According to the findings, the highest correlation (more than 95%) of skin cancer in three cities of Parsabad, Khalkhal, and Ardabil with the climatic parameter was related to minimum absolute temperature. However, in Khalkhal station in three years of study, sunny hours had the highest correlation and the lowest correlation was related to glacial climate parameter in all four cities. It can be said that the factors of sunny hours and maximum temperature have an effect on the incidence of skin cancer, and the minimum absolute temperature increases the exacerbation of this type of disease. Conclusion: According to the results of statistical correlation and the effects of climatic parameters on skin cancer, it can be concluded that climate parameters are one of the effective factors in skin cancer.
本研究调查了其中一种疾病(皮肤癌)及其与气候参数的关系。本研究的目的是调查阿达比勒省气候变化与皮肤癌之间的关系。材料与方法:采用描述性相关研究方法，对2012-2014年3年统计期阿达比尔省6个气候参数(霜冻、日照时数、最低平均湿度、最高绝对温度、最低绝对温度和平均温度)对皮肤癌的影响进行研究。采用SPSS version 24软件进行Spearman相关关系分析，并采用Minitab version 16软件进行线性插值。结果:根据研究结果，在Parsabad、Khalkhal和Ardabil三个城市，皮肤癌与气候参数的最高相关性(超过95%)与最低绝对温度有关。而在Khalkhal站3年的研究中，4个城市的日照时数与冰川气候参数的相关性最高，相关性最低。可以说，日照时数和最高气温等因素对皮肤癌的发病率都有影响，而最低绝对气温则增加了这类疾病的加重。结论:根据统计相关结果和气候参数对皮肤癌的影响，可以得出气候参数是皮肤癌发生的有效因素之一。

Introduction: One of the ways of human exposure to aluminum (Al) is Al food packaging materials and cookwares. Although many studies have examined the biotic influence of nanoparticles or ionic form of heavy metals, there are limited studies conducted on the possible health risks of metals in the form of alloy used for making utensils. In this study, the effect of water boiled in Al cookwares with defined concentrations of Al on the genomic abnormalities and cell division of meristematic cells of onion root was evaluated using Allium cepa assay. Materials and Methods: The onion roots were treated with water boiled in Al utensils (three pots) with different concentrations of Al (5 and 10 mg/l) for 42 to 43 hours and then analyzed for mitotic index (MI) and mitotic phase aberrations (MPA). Results: The percent of MI in the study groups treated with 5 mg/l of Al from pot 1 and 10 mg/l from all pots increased significantly compared to the control group (P < 0.05). Also, the frequency of total MPA in all Al treated groups significantly increased compared to the control group (P < 0.05). The most significant results were derived by sticky chromosomes, anaphase bridge, going ahead chromosome and disturbed mitosis, respectively. Conclusion: The result of this study confirmed the genotoxic effect of water boiled in Al cookwares containing the examined range of Al concentrations on the meristematic cells of onion root.

Introduction: Food insecurity has negative impacts on health, including the function of the immune system. The association between food insecurity and COVID-19 infection rates has not been fully understood. This study aimed to examine whether food-insecure households are more vulnerable to COVID-19 infection. Materials and Methods: This online cross-sectional study was conducted on 2,871 Iranian adults (31 provinces), from August to September 2020. Demographic and socio-economic information was collected using a questionnaire. The Household Food Insecurity Access Scale (HFIAS) was used for assessing household food insecurity. The data analysis was performed by SPSS.22, using Chi-square test, ANOVA test, and Multinomial Logistic Regression Model. Results: The findings indicated that healthcare personnel were at higher risk of COVID-19 (CI = 1.90, 7.05; OR = 3.66; P < 0.001). It was also shown that HFIAS scores were significantly higher among infected people compared to non-infected (CI = 1.00, 1.05; OR = 1.03; P < 0.05). Women were at lower risk of infection compared to men (CI = 0.41, 0.87; OR = 0.60; P < 0.05). Conclusions: Based on the results, in addition to long-term policies to improve food security, policymakers are recommended to implement short-term policies to reduce the vulnerability of the community to COVID-19 virus.

Introduction: Macrolides are a group of antibacterial agents. Given their clinical importance, and the consistent rise in resistance among pathogenic bacteria, macrolides have been the targets of extensive research. Materials and Methods: This review considered the number of macrolides in different wastewater and the removal of these drugs. The antibiotics were frequently detected in influents and effluents, ranged from ng/L up to lower μg/L. In influent, the highest concentrations of clarithromycin (6080 ng/L), roxithromycin (>103 ng/L), erythromycin (3900 ng/L), and azithromycin (1949 ng/L) were detected in Croatia, Chinese, USA, and Singapore municipal wastewater treatment plants, respectively. Results: The removal efficiency of macrolides during wastewater treatment processes varies and is essentially dependent on a combination of macrolides physicochemical properties, location of municipal wastewater, and the operating conditions of the treatment systems. The application of alternative techniques, including membrane separation, activated carbon adsorption, advanced oxidation processes, biodegradation, and disinfection were the dominant removal routes for macrolides in different wastewater treatment processes. A combination of these techniques can also be used, leading to higher removals, which may be necessary before the final disposal of the effluents or their reuse for irrigation or groundwater recharge. Conclusion: Many antibiotics cannot be removed completely in wastewater treatment processes and would enter into the environment via effluent and sludge. The molecular structure of macrolides and their load-bearing capacity has led to the advantage of biological treatment over other treatments. However, the main part of the treatment has been done using biological treatment.

Introduction: Safety and health risk assessment in industries is associated with uncertainties due to the variables affecting it. Therefore, in this research, optimizing safety and health risk assessment was investigated in construction sites by combining a multi-criteria decision-making technique (TOPSIS) and a fuzzy system. In the present study, to answer this question, a new method was used to optimize health risk assessment in construction workshops. Materials and Methods: The case study was construction sites in Lar, a city in the south of Iran. Based on previous studies and expert opinions, ten criteria were determined to assess safety and health risks in the construction sites. Also, 15 safety and health risks were identified resulting from 12 types of activities in the construction sites. Triangular fuzzy numbers were used for linguistic variables in Fuzzy TOPSIS with R version 1.1 software. Results: Based on the results, the risk of the collapse of adjacent buildings related to the excavation process was the most important safety and health risk in the construction sites with a coefficient value of 0.5. Conclusion: This method can provide desired results with the least uncertainty in prioritizing safety and health risks.

Introduction: Extreme weather or climate, including heat waves and cold waves, is considered a health issue causing adverse effects on health, such as cardiovascular diseases (CVDs), mortality and morbidity. Thus, this systematic review aimed to study the impacts of extreme ambient temperature on cardiovascular outcomes. Material and Methods: This study was carried out based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol. Papers about the ambient temperature and cardiovascular outcomes were searched in the scientific database, including ISI, PubMed, Scopus, and Google Scholar, from January 1970 up to the end of 2020. We used the key terms, such as “heat wave”, “cold wave”, “extreme event”, “cardiovascular disease”, “mortality”, and “morbidity”. The thematic analysis method was used to determine all themes and analyze the data. Results: Among the 7631 searched and extracted papers, 20 articles met the eligibility criteria for including the process of final analysis. Effects of extreme events included mortality, morbidity, and hospitalization due to CVD. A relationship between extreme events and CVD mortality was confirmed for cerebrovascular diseases, including congestive heart failure (CHF), ischemic heart diseases (IHD), myocardial infarction (MI), cardiac arrhythmia, coronary heart disease (CHD), out-of-hospital cardiac arrest (OHCA), acute coronary syndrome (ACS), and blood pressure. Conclusion: The present study indicated the impact of extreme ambient temperature on CVD outcomes. The findings provided adaptation and preventive measures and strategies which can be used for CVD patients and managers to prevent CVD due to ambient temperature.

Introduction: Global warming is one of the most important environmental problems that have raised researchers’ attention. The present study aimed to analyze heat stress trends using the Wet Bulb Globe Temperature (WBGT) index in the country of Iran during the summer over a 30-year period. Materials and Methods: Daily summertime statistical data regarding mean temperature and mean relative humidity, taken from 40 synoptic meteorological stations across Iran during a 30-year period were obtained from the Iranian National Meteorological Department. The De Martonne climate classification system was used to categorize various climate regions of Iran. The WBGT index was calculated using the formula given by the Australian Bureau of Meteorology. The Mann-Kendall statistical test and the Sen's slope estimator were used to analyze the trends of the WBGT index. Results: The WBGT index had an upward trend during the three months of June, July, and August in 71.42%, 57.14%, and 66.66% of all stations and this trend was statistically significant in 53.32%, 50%, and 42.85% of those stations, respectively. Moreover, throughout the summer, 45% of the WBGT index measurements were in the medium range (18-23°C), 37.5% were in the high range (23-28°C), and 17.5% were in the very high range (> 28°C). Conclusion: The WBGT index followed an upward trend during the summer, especially in semi-arid regions of Iran. Considering the phenomenon of global warming, it is essential to monitor, plan ahead, and take necessary precaution measures for sensitive populations who are at high risk areas of the country.

Introduction: The use of wastewater for irrigation in arid and semi-arid regions of the world is increasing. This study aimed to evaluate the effects of wastewater on the microbial activity of irrigated soils using the enzymatic activity of soil microorganisms. Materials and Methods: In this study, for soil irrigation, the secondary effluent of the Isfahan municipal wastewater treatment plant was used. As a control, tap water that has no microbial load was also used. Soil samples were collected in two stages, before and immediately after irrigation. All samples were collected in sterile bags, transferred immediately to the laboratory for physicochemical and microbiological tests. Soil samples were analyzed for the amounts of enzymatic activity (Fluorescein Diacetate (FDA) and dehydrogenase), electrical conductivity (EC), oxidation-reduction potential (ORP), and pH. Results: The EC levels before and after irrigation with tap water was 231.2 and 260.63 µs.cm-1, respectively, which was significantly different from levels of wastewater-irrigated soil (P < 0.05). pH in the two types of used water before and after irrigation was 6-8 and 7-8, respectively. No significant difference was observed in the levels of FDA, dehydrogenase, ORP, and microbial population in samples irrigated with water and wastewaters (p > 0.05). It was found that there is a significant relationship between bacterial density and FDA (P < 0.05). Conclusion: The results of the study showed that irrigation with wastewater has no significant effect on the microbial activity of irrigated soil. Because of the short-term wastewater irrigation in the present study, however, further investigation is needed to evaluate the effect of long-term wastewater irrigation on the microbial and physicochemical quality of soil.

Soil samples were analyzed for the amounts of enzymatic activity (Fluorescein Diacetate (FDA) and dehydrogenase), electrical conductivity (EC), oxidation-reduction potential (ORP), and pH. \u0000Results: The EC levels before and after irrigation with tap water was 231.2 and 260.63 µs.cm-1, respectively, which was significantly different from levels of wastewater-irrigated soil (P < 0.05). pH in the two types of used water before and after irrigation was 6-8 and 7-8, respectively. No significant difference was observed in the levels of FDA, dehydrogenase, ORP, and microbial population in samples irrigated with water and wastewaters (p > 0.05). It was found that there is a significant relationship between bacterial density and FDA (P < 0.05). \u0000Conclusion: The results of the study showed that irrigation with wastewater has no significant effect on the microbial activity of irrigated soil. Because of the short-term wastewater irrigation in the present study, however, further investigation is needed to evaluate the effect of long-term wastewater irrigation on the microbial and physicochemical quality of soil.","PeriodicalId":53380,"journal":{"name":"Journal of Environmental Health and Sustainable Development","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46376857","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Introduction: Cutaneous leishmaniasis is one of the health concerns in Iran. Numerous studies have examined the role of blood type in people with the disease. Therefore, this study aimed to investigate the prevalence of leishmaniasis in different blood groups as a review in Iran. Materials and Methods: For this review, two researchers evaluated the extracted articles in terms of relevance to the purpose of the study after searching four databases, including Scopus, Web of Science, PubMed, and Science Direct. Literature reports on the prevalence of leishmaniasis in different blood groups in Iran until the end of March 2021. Relevant information included study time, study tool, number of subjects, mean age, and the relationship between blood type and infection which were recorded in Excel form. Results: After searching, screening, and qualitative evaluation of the studies, out of 135 identified articles, five papers met the required requirements. These five articles were published from 1999 to 2012, three studies examined the relationship between cutaneous leishmaniasis with different age groups. Also, three studies experimentally evaluated the relationship between cutaneous leishmaniasis with different human blood groups. Conclusion: According to the results of the present review, cutaneous leishmaniasis is more common in some blood groups. Studies have shown that Rh-negative blood groups with B alleles are more affected by cutaneous leishmaniasis than others; however, more studies are required.
引言：皮肤利什曼病是伊朗的健康问题之一。许多研究已经检验了血型在该疾病患者中的作用。因此，本研究旨在调查利什曼病在伊朗不同血型中的流行情况。材料和方法：在这篇综述中，两名研究人员在搜索了Scopus、Web of Science、PubMed和Science Direct四个数据库后，根据与研究目的的相关性对提取的文章进行了评估。截至2021年3月底，伊朗不同血型利什曼病流行率的文献报告。相关信息包括研究时间、研究工具、受试者人数、平均年龄以及血型与感染之间的关系，并记录在Excel表格中。结果：经过搜索、筛选和定性评估，在135篇已鉴定的文章中，有5篇符合要求。这五篇文章发表于1999年至2012年，三项研究考察了不同年龄组皮肤利什曼病之间的关系。此外，三项研究通过实验评估了皮肤利什曼病与不同人类血型之间的关系。结论：根据本综述的结果，皮肤利什曼病在某些血型中更常见。研究表明，具有B等位基因的Rh阴性血型比其他血型更容易受到皮肤利什曼病的影响；然而，还需要更多的研究。
