Methods: In this descriptive-analytical study being of cross-sectional type, hearing status of 34 male workers was investigated. In the present study, workers were divided to 3 occupational groups; mechanics, turner and millers, and welders, and to determine a more exact noise exposure level based on network methodology, dosimeter was done using a TES 1358 audiometer for each group. Statistical analysis was performed with the SPSS 16 statistical software using correlations, Analysis of Variance (ANOVA) and independent-samples t test.

Results: The average age and work experience of the subjects was 36.58 ± 7.48 and 11.11 ± 6.8 years, respectively. No significant relationship was observed between sound pressure level and work experience with hearing loss (P > 0.05), yet a significant relationship was found between the decline in hearing threshold in 3000 Hz, 4000 Hz, and 6000 Hz frequencies in the left ear and a frequency of 8000 Hz in the right ear and work experience (P ≤ 0.05). The relationship between age and Noise-Induced Hearing Loss (NIHL) was significant (P ≤ 0.05).

DOI: 10.5812/jjhs.14166

PDF

Background: The wastewater of alcohol plants is called Vinasse. After conversion of molasses to alcohol and other derivatives, this compound must be removed as waste from the factory. If released without careful planning and proper management and supervision, this wastewater can cause serious and several social, economic, and environmental consequences. Therefore, it is very important to eliminate heavy elements before the waste goes deep into the soil or to underground water reservoirs.

Methods: To evaluate the potential of Vermiculite and Zeolites in refinement of metal pollutants cadmium and lead, 2 irrigation periods by Vinasse and 3 treatments were conducted. First, the soil of the region was irrigated by Vinasse up to the saturation level. Second, the soil of the region with 2 layers of Zeolites in the depths of 25 cm and 50 cm was irrigated by Vinasse up to the saturation level. Third, the soil of the region with 2 layers of Vermiculites (same depths as treatment two) was irrigated by Vinasse up to the saturation level. The experiment was performed within columns with diagonal of 90 mm and height of 1000 mm. Surface irrigation (flooding) with the volume of 2.3 l was conducted every 5 days. Sampling in the depths of 15 - 25 cm and 40 - 50 cm of soil columns and drained water from the bottom of the soil columns were collected 24 hours after each irrigation and samples were taken to a laboratory to perform chemical analysis.

Results: The results showed that before the experiment, the amounts of lead and cadmium in soil were 2.6 mg/kg and 42.0 mg/kg, respectively. As for Vinasse, the amounts were 46.2 and 7.11 mg/kg, respectively. After irrigation by Vinasse in the depth of 15-25 in treatments 1, 2, and 3, the increases in the level of cadmium were 0.034, 0.042, and 0.04 mg/kg, respectively. In addition, the increases in the level of lead in the depth of 30-50 in treatments 1, 2, and 3 were 0.28, 0.036, and 0.034 mg/kg, respectively.

DOI: 10.5812/jjhs.14059

PDF

Methods: In this descriptive study, 30 samples from 10 brands of sausage and 30 samples from 10 brands of ham (totally 60 samples) were collected from the market basket of Hamadan city. After preparation and processing of the samples in the laboratory, the concentration of metals was determined using inductively coupled plasma-optical emission spectrometry. The health risk index (HRI) was assessed based on the ratio of average daily intake of metal (DIM) to the reference dose of the metal. All statistical analyses were performed using SPSS (version 20).

Results: The results showed that the mean concentrations (mg/kg) of Cu, Pb, and Zn were 1.88 ± 0.69, 0.35 ± 0.18, and 4.61 ± 1.71 in sausage samples and 1.48 ± 0.25, 0.32 ± 0.11, and 3.18 ± 1.28 in ham samples. Pb was higher than the maximum permissible level (0.20 mg/kg) in 80% of the samples. In addition, the computed health risk index showed no potential risk for adults and children via consumption of studied foodstuffs.

Conclusions: According to the results, the HRI values of analyzed processed meat products were within the safe limits and there was no potential health risk for human through the consumption of them under the current consumption rate. However, considering that the mean content of Pb in 80% of the samples exceeded the MPL, serious attention should be paid to the discharge of pollutants to the environment, chemicals residue monitoring especially for toxic heavy metals in foodstuff, and control of heavy metals content during the whole production process of sausage and ham.

Fatemeh Ghannadiasl, Reza Mahdavi

DOI: 10.5812/jjhs.55557

PDF

Results: The participants demonstrated a significant weight loss and improvement in total self-efficacy score in both the intervention groups (the time effect: F = 12.64, df = 2, P < 0.001, F = 22.57, df = 2, P < 0.001, respectively). No significant difference was observed in the social pressure subscale between the two groups after the intervention (the time × intervention effect: F = 2.80, P > 0.05). The results showed that nutrition education could be more effective in the increase of self-efficacy, especially in the first 3 months in comparison with the second 3 months (1.01 ± 0.38 vs. 0.29 ± 0.17, P = 0.005).
