Background: Studying human health in areas with industrial contamination is a serious and complex issue. In recent years, attention has increasingly focused on the health implications of large industrial complexes. A variety of potential toxic chemicals have been produced during manufacturing processes and activities in industrial complexes in South Korea. A large number of dyeing industries gathered together in Daegu dyeing industrial complex. The residents near the industrial complex could be often exposed to volatile organic compounds. This study aimed to evaluate VOCs levels in the ambient air of DDIC, to assess the impact on human health risks, and to find more convincing evidences to prove these VOCs emitted from DDIC.
Methods: According to deterministic risk assessment, inhalation was the most important route. Residential indoor, outdoor and personal exposure air VOCs were measured by passive samplers in exposed area and controlled area in different seasons. Satisfaction with ambient environments and self-reported diseases were also obtained by questionnaire survey. The VOCs concentrations in exposed area and controlled area was compared by t-test. The relationships among every VOC were tested by correlation. The values of hazard quotient (HQ) and life cancer risk were estimated.
Results: The concentrations of measured VOCs were presented, moreover, the variety of concentrations according the distances from the residential settings to the industrial complex site in exposed area. The residential indoor, outdoor, and personal exposure concentrations of toluene, DMF and chloroform in exposed area were significantly higher than the corresponding concentrations in controlled area both in summer and autumn. Toluene, DMF, chloroform and MEK had significantly positive correlations with each other in indoor and outdoor, and even in personal exposure. The HQ for DMF exceeded 1, and the life cancer risk of chloroform was greater than 10 in exposed area. The prevalence of respiratory diseases, anaphylactic diseases and cardiovascular diseases in exposed area were significantly higher than in controlled area.
Conclusions: This study showed that adverse cancer and non-cancer health effects may occur by VOCs emitted from DDIC, and some risk managements are needed. Moreover, this study provides a convenient preliminarily method for pollutants source characteristics.

The European pond turtle (Emys orbicularis) is a wide-ranging, long-living freshwater species with low reproductive success, mainly due to high predation pressure. We studied how habitat variables and predator communities in near-natural marshes affect the survival of turtle eggs and hatchlings. We followed the survival of artificial turtle nests placed in marshes along Lake Balaton (Hungary) in May and June as well as hatchlings (dummies) exposed in September.

This study presents a web application for predicting cardiovascular disease (CVD) and hypertension (HTN) among mine workers using machine learning (ML) techniques. The dataset, collected from 699 participants at the Gol-Gohar mine in Iran between 2016 and 2020, includes demographic, occupational, lifestyle, and medical information. After preprocessing and feature engineering, the Random Forest algorithm was identified as the best-performing model, achieving 99% accuracy for HTN prediction and 97% for CVD, outperforming other algorithms such as Logistic Regression and Support Vector Machines.

Background: Ozone (O) is a promising alternative antibacterial agent that has recently been used in meat processing. The understanding of the appropriate functional settings of O for addressing food safety problems is still insufficient.
Aim: The aim of this study was, therefore, to investigate the effects of exposure to O on the bacteriological quality of retail meat inoculated with at refrigeration temperatures.

Human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV) are known as the most common blood-borne viral infections worldwide. Individuals referring to drop-in centers (DICs) are considered high-risk people exposed to infection with blood-borne viruses. The purpose of this study was to investigate the prevalence of HIV, HBV, and HCV infections among women referred to DICs in Lorestan Province, western Iran.

The aim of this study was to investigate the effects of ultrasound at two different frequencies, namely 30 kHz and 42 kHz, on various aspects of industrial Iranian honey, including its physical, biochemical, antioxidant and antimicrobial properties. Samples were subjected to ultrasound treatment at 30 kHz or 42 kHz for a duration of 1, 5 or 10 minutes at temperatures of 20 °C or 45 °C, respectively. The following parameters were then evaluated on days 1, 30, 90, and 180: HMF content, pH, acidity, proline concentration, total number of aerobic mesophilic bacteria, diastase activity, moisture content, sucrose concentration, fructose concentration, glucose concentration, fructose- glucose ratio, ABTS (antioxidant activity) content, number of osmophiles, phenol concentration, reducing sugar concentration and total sugar concentration.
