Pneumoconiosis refers to a class of serious diseases threatening the health of workers exposed to coal or silicosis dust. However, the burden of pneumoconiosis is unavailable in China. Incident cases, deaths, and disability-adjusted life years (DALYs) from pneumoconiosis and its subtypes in China were estimated from the Global Burden of Disease Study 2019 using a Bayesian meta-regression method.

Dental technicians are at high risk of pneumoconiosis, usually driven by inhalation of mixed dusts, including metals. An etiological diagnosis is not easy to be performed, particularly in advanced stages.

Idiopathic Pulmonary Fibrosis (IPF) is an aggressive interstitial lung disease with an unpredictable course. Occupational dust exposure may contribute to IPF onset, but its impact on antifibrotic treatment and disease prognosis is still unknown.

Sinonasal cancer (SNC) has been related to occupational exposures, but the relative risk associated to specific jobs and/or carcinogen exposures other than wood and leather dust is generally based on small or inadequate sample sizes and the range of observed estimates is large. This paper is aimed at investigating such relationship through a systematic review of the literature followed by a meta-analysis of studies meeting specific inclusion criteria.

Lung cancer is the leading cause of cancer death in North America. Exposure to cotton dust has previously been reported to decrease the risk of lung cancer. Methods: We used data from two large case-control studies conducted in Montreal from 1979-1986 (Study 1) and 1996-2002 (Study 2) respectively, to examine the association between occupational exposure to cotton dust and risk of lung cancer.

The use of personal protective equipment is essential for preventing and controlling diseases experienced by poultry farm workers as respiratory ill health among poultry farm workers has been strongly associated with working in poultry farms. The current study was carried out to determine the respiratory health problems prevalent and the level of utilization of personal protective equipment among the poultry farm workers. The study was carried out between April and May 2018.

Microorganisms from dusts of organic origin was identified from some saw mill, (Site 1) and a poultry farm (Site 1) in Port Harcourt. The exposure to these organic dusts by people employed in these establishments over a long period of time can lead to occupational health diseases especially in immune compromised persons. Nutrient Agar, Sabaroud Dextrose Agar (SDA), and Mac Conkey Agar (MA) in sedimentation method were used to isolate microorganisms.

Silicosis is an incurable lung disease affecting millions of workers in hazardous occupations. It is caused by chronic exposure to the dust that contains free crystalline silica. Silica-induced lung damage occurs by several main mechanisms including cell death by apoptosis, fibrosis and production of cytokines.

Until well into the twentieth century, serious accidents and occupational hazards leading to disease were a normal part of working life for millions of the working population. People were made deaf by excessive noise in mills, burned by slag and molten metal in foundries, their lungs wrecked by dust in mining and farming, their organs poisoned by lead in paints or mercury used in making hats.

The European Union’s CAREX database of occupational exposures to carcinogens estimated that in the early 1990s 22-24 million workers in the then 15 EU member states were exposed to carcinogens classified as group 1 by the International Agency for Research on Cancer – those known to cause cancer in humans. Overall, 32 million workers, 23 per cent of the working population, had workplace exposures associated by the CAREX database with an occupational cancer risk.

Approximately 75% of COPD cases are attributed to cigarette smoking (5). Occupation-related exposures may account for another 15% of COPD cases (6) and genetic factors, asthma, respiratory infections, and indoor and outdoor exposures to air pollutants also play a role (6,7). hus, COPD largely can be prevented. Prevention of COPD begins with reducing and/ or eliminating smoking initiation among teenagers and young adults and encouraging tobacco cessation among current smokers.

Environmental toxins, including exposure to lead, pesticides, and other chemicals, unquestionably affect fertility in men and women. Researchers have documented many examples, the strongest cases involving industrial and occupational exposures. These usually involve small numbers of people exposed to high levels of contamination.

The lungs are the main route for dust entering the human body. Dust deposition in the pulmonary system varies considerably according to the granulometry of ultrafine dusts and their airborne behaviour. Normally, for coarser dusts encountered in work environments, the proportion of dusts deposited in the alveolar region increases as particle diameter decreases, reaching a maximum value of around 20% for 3-micrometre particles. This percentage then diminishes gradually.
