Background/aim: Since street sweepers comprises a group of workers who are in daily contact with rubbish, dust and air pollution, the aim of this study was to evaluate potential cytotoxic and mutagenic effects in buccal mucosa cells of street sweepers.
Materials And Methods: A total of 20 male street sweepers aged from 22 to 56 years were included in the experimental group. A total of 20 men matched by age were used as the control group. Cytotoxicity and mutagenicity were analyzed by micronucleus test in buccal mucosal cells.
Results: Statistically significant differences (p<0.05) in the frequency of micronuclei was detected in the street sweepers when compared to the control group. No remarkable differences were found to other metanuclear alterations indicative for cytotoxicity such as pyknosis, karyolysis, and karryorhexis when compared to matched controls.
Conclusion: Taken together, our results indicate that street sweepers comprise an at-risk group as a result of increased mutagenicity found to buccal mucosa cells.

Occupation-related respiratory diseases among sanitary workers in the workplace: a systematic review and meta-analysis.

Introduction: Emerging evidence from both developed and developing countries indicates that occupation-related respiratory diseases (ORRD) among sanitary workers constitute a significant public health challenge. These are because of the working environment, where employees are more likely to be at risk in an unsafe workplace, especially sanitary workers. Therefore, the purpose of this systematic review and meta-analysis was to estimate the prevalence of ORRD among sanitary workers.

Despite the significant risks faced by these workers, the issue has received limited attention, and no comprehensive global meta-analysis on occupational injuries among sanitary workers has been conducted to date.
Objective: In this study, we aimed to conduct a systematic review and meta-analysis of occupational injuries among sanitary workers globally from 2000 to 2023.

Road dust is a demonstrated source of urban air pollution. Given this, the implementation of street sweeping strategies that effectively limit road dust accumulation and resuspension should be a public health priority. Research examining the effectiveness of street sweeping for road dust removal in support of good air quality has been limited to date.

Solid waste has been a major problem particularly in Sub-Saharan Africa countries as it has been increasing in several years. One of the methods employed in solid waste management is street sweeping which is done by street sweepers. Street sweepers are being predisposed to respiratory and non-respiratory infection like eye infection, skin infection and musculoskeletal disorders.
