Background: There is limited research concerning how small companies in particular, respond to health and safety messages. Aims: To understand individuals’ knowledge and beliefs about chemical risks and to compare these with those of experts. Methods: The use of chromic acid in particular, and also other chemicals associated with chrome plating were studied. Methods. OVID and PubMed were searched using the terms occupational asthma, work-aggravated asthma, irritant-induced asthma, and reactive airway dysfunction syndrome (RADS) alone and in combination with epidemiology, diagnosis, and primary literature and recent reviews were included to create a document that can be used by the practicing allergist to assess and .
This article aims to review the available literature regarding the link between occupational exposure to pesticides and respiratory symptoms or diseases. Identification of epidemiological studies was performed using PubMed. 41 articles were included, 36 regarding agricultural workers and five regarding industry workers. Among the 15 cross-sectional studies focusing on respiratory symptoms and. Occupational asthma is asthma caused by, or worsened by, exposure to substances in the workplace. These substances may cause asthma in one of 3 ways. An allergic reaction (like people with.
1. Introduction. Occupational asthma (OA) is defined as “a disease characterized by variable airflow limitation and/or hyper-responsiveness and/or inflammation due to causes and conditions attributable to a particular occupational environment and not to stimuli encountered outside the workplace” .Two types of OA are distinguished based on their appearance after a latency period or in. asthma frequently co-occur; the same is true for occupational rhinitis and asthma. Occupational rhinitis can indicate that there is a risk of developing occupational asthma, the risk being highest in the year after the onset of rhinitis. Recognition and diagnosis The diagnosis of asthma is based on the recognition of a charac-.

Recent developments in the field of occupational asthma research and clinical practice are the topic of this volume. The contribution of occupational exposures to chemical and biological agents to the burden of asthma in adults is clearly described in an overview of the most recent epidemiological data from both general population and industry based studies.
Occupational or professional asthma is defined as adult asthma, i.e., an inflammatory respiratory disease characterized by the presence of variable airflow limitation or bronchial hyperreactivity secondary to conditions and causes associated with a given occupational or working environment – not with stimuli ound outside the by: By major industry, current asthma prevalence was highest among workers in the major industry groups of health care and social assistance (%) followed by educational services (%) ; these groups also had the first and second highest numbers of workers with asthma attacks (, andrespectively) and asthma-related ED visits Cited by: This article reviews recent developments in the study of occupational asthma and implications for the overall understanding of asthma.
Occupational asthma is a clinical syndrome caused by many different agents. Contribution of studies of experimental inhalation challenge using occupational agents to the knowledge of asthmatic reactions and their mechanisms is discussed.
Current Asthma by Industry. The burden of asthma in a given industry or occupation is the result of a variety of factors including the proportion of workers with asthma and the number of workers employed in each industry or occupation.

Eur Respir J ; 22(3) Prevalence of occupational asthma. Towards the end of the 20th century, just as other work-related respiratory illnesses, such as pneumoconiosis, were on the decline in industrialised countries, the prevalence and incidence of OA began to increase 1, This may have been due, at least in part, to changing environmental conditions inthe workplace, i.e.

The prevalence of asthma in red cedar sawmills is an excellent exampleJn. There is a large variation in the prevalence/incidence of potroom asthma in the aluminum industry, from % to 4% of exposed workers, with a low prevalence in North American studies compared with Scandinavian studies.

Occupational asthma -- Metal plating industry: A respiratory condition caused by exposure to metals in a metal plating industry workplace environment.
The severity of symptoms varies between people. Asthma is common among adults of working age and affects 5–10% of the population worldwide.
Occupational asthma has become a common work related respiratory disorder in the industrialised world.1 Blanc and Toren have shown that 9% of cases of adult asthma—including principally new onset asthma and, much more rarely, reactivation of pre-existing asthma—are attributable to occupational.
Occupational asthma. Occupational asthma is asthma caused by some aspect of the workplace environment. 2 It is important to distinguish occupational asthma from aggravation of pre-existing asthma, because the management and compensation can differ.
The more common type of occupational asthma, accounting for over 90% of cases, is sensitizer-induced occupational asthma.
Introduction. Asthma is among the most common chronic diseases in working-aged populations. Among the general adult population in high income countries, it has been estimated that 2–5% of patients with asthma have occupational asthma [1,2]; some studies from the United States and Japan have estimated the risk to be as high as 15% .Among populations at risk due to their exposure to known.
Occupational Asthma – inhalation of hexavalent chromium, nickel and cadmium mists. Occupational asthma is an allergic reaction that can occur in some people when they are exposed to substances.
In electroplating and similar processes these can include hexavalent chromium compounds and. Occupational asthma symptoms are the same as any asthma exacerbation, such as wheezing, shortness of breath, runny nose, nasal congestion, eye irritation, and chest tightness.
These symptoms may get worse during exposure to the irritant(s) at work. Work-related asthma is asthma triggered by an exposure at work. Many asthma triggers can be found in the workplace. Over known or suspected substances in the workplace can cause or worsen asthma.
Avoiding triggers can prevent asthma from getting worse. Worsening asthma or new onset asthma in a worker should raise questions about workplace. Disinfectant use has been associated with adverse respiratory effects among healthcare workers.
However, the specific harmful agents have not been elucidated. We examined the association between occupational exposure to disinfectants and asthma control in the Nurses' Health Study II, a large cohort of female nurses.
Nurses with asthma were invited in to complete two questionnaires on. Occupational asthma is the most prevalent form of occupational lung disease in industrialized nations. As increasing numbers of new chemicals are produced and new manufacturing processes are introduced, the variety of environments in which individuals may become exposed to respiratory sensitizers and irritants makes diagnosing and treating this illness even more challenging.
Asthma Surveillance Data. Asthma surveillance data includes collection of asthma data at both the national and the state level. National data is available on asthma prevalence, activity limitation, days of work or school lost, rescue and control medication use, asthma self-management education, physician visits, emergency department visits, hospitalizations due to asthma, and deaths .Also used in the oil and gas industry for the inhibition of corrosion causing bacteria C12 Some hardwood dusts A general term covering a wide variety of wood dusts.
