“…Many researchers have observed a reduced lung function parameters e.g. PEFR, forced expiratory volume one second (FEV 1 ) and forced vital capacity (FVC) in woodworkers when compared to the general population (Fernandez-Rivas et al, 1997;Ige & Onadeko, 2000). Present research shows that as the year of exposure to wood dust increases percentage of workers with abnormally reduced PEFR increases, further re-enforcing increasing presence of obstructive pathology with increasing years of exposure to wood dust.…”

Abstract:Wood dusts are known to cause respiratory disorders like rhinitis and asthma. This study was therefore done to determine the magnitude of the problem among woodworkers in south-eastern Nigeria exposed to high level of wood dust. Five hundred and ninety one woodworkers were selected using a stratified random sampling. The prevalence of woodworkrelated rhinitis and asthma were then observed in the study population. Also the peak expiratory flow rate (PEFR) of each woodworker was obtained. The prevalence of occupational rhinitis was 78%, while that of asthma was 6.5%. As period of woodwork increased the prevalence of rhinitis and asthma increased (rhinitis: χ 2 trend = 53.015, df = 1, P = 0.000). For asthma, χ 2 trend =19.721, df = 1, P = 0.000). Also the PEFR significantly became low with increasing years of exposure to woodwork (χ 2 trend = 75.965, df = 1, P= 0.000). In conclusion the prevalence of rhinitis and asthma in woodworkers was high and significantly increased with years of working as a woodworker.

“…As the investigations were carried out at the workplace, we were not able to investigate IgE antibodies, so our discussion on potential mechanisms remains speculative. Some case reports of occupational asthma and/or rhinitis have measured IgE to specific species of wood, suggesting a type I hypersensitivity reaction,3 6 while type IV hypersensitivity has been suggested to play a role in occupational dermatitis 5. The mechanism underlying red cedar asthma seems to be based on immunological reactions other than type I hypersensitivity 28.…”

Respiratory and skin effects of exposure to wood dust from the rubber treeHevea brasiliensis

This study provides new evidence that workers exposed to wood dust from the rubber tree experience increased risk of nasal symptoms, wheeze, asthma and skin symptoms and have reduced spirometric lung function. Exposure to cyanoacrylate is related to significantly increased respiratory symptoms. Results suggest that the furniture industry using rubber tree wood should implement appropriate exposure control measures to reduce wood dust exposure and cyanoacrylate glue exposure to protect their employees.

Summary1. This account presents information on all aspects of the biology of Fraxinus excelsior L. (Ash) that are relevant to understanding its ecological characteristics and behaviour. The main topics are presented within the standard framework of the Biological Flora of the British Isles: distribution, habitat, communities, responses to biotic factors, responses to environment, structure and physiology, phenology, floral and seed characters, herbivores and disease, history, and conservation. 2. Fraxinus excelsior is a large forest tree, native throughout the main islands of Britain and much of mainland Europe. Seedlings are shade tolerant, but adults are not so it tends to be an intermediate successional species, invading gaps in mixed stands rather than forming extensive pure stands. Ash grows on a wide range of soils but is commonest on nutrient-rich soils with a high base status and pH > 4.2, and is at its best on dry calcareous screes and fertile alluvial soils. 3. Fraxinus excelsior is trioecious or subdioecious with male, hermaphrodite and female flowers and trees. Seed production is prolific with periodic higher producing mast years. Seeds are primarily wind-dispersed, but they can float and be moved considerable distances along waterways. Germination is delayed by dormancy until usually the second spring after being shed. 4. Ash is tolerant of drought, but intolerant of spring frosts and so is predicted to fare well under current climate change scenarios, and indeed has recently been expanding in range in Europe. However, ash health and survival is currently seriously compromised by ash dieback caused by the fungus Hymenoscyphus fraxineus (Chalara fraxinea) that has the potential to kill all but a very few resistant trees. Moreover, the emerald ash borer beetle Agrilus planipennis, a serious pest of ash species in N. America, has reached Europe (though not yet the British Isles) and poses an equally if not more serious long-term threat to ash.
