- There are increasing reports of allergies and respiratory symptoms among workers in the fish processing industry, coinciding with an increasing use of high-pressure water in the processing plants. However, few studies have measured exposure in these work environments.

- This investigation was triggered by three cases of asthma-about 10% of the workforce-occurring in a salmon processing plant over a short period of time. The aim of the investigation was to characterize the work exposure of inhalable organic particles with personal measurements. Respiratory symptoms at work among workers were also assessed.

- The goal of this study was to identify occupational risk factors for severe exacerbation of asthma and estimate the extent to which occupation contributes to these events. The 966 participants were working adults with current asthma who participated in the follow-up phase of the European Community Respiratory Health Survey. Severe exacerbation of asthma was defined as self-reported unplanned care for asthma in the past 12 months. Occupations held in the same period were combined with a general population job-exposure matrix to assess occupational exposures. 74 participants reported having had at least one severe exacerbation event, for a 1-yr cumulative incidence of 7.7%. From regression models that controlled for confounders, the relative risk (RR) was statistically significant for low (RR 1.7, 95% CI 1.1-2.6) and high (RR 3.6, 95% CI 2.2-5.8) biological dust exposure, high mineral dust exposure (RR 1.8, 95% CI 1.02-3.2), and high gas and fumes exposure (RR 2.5, 95% CI 1.2-5.5). The summary category of high dust, gas, or fumes exposure had RR 3.1 (95% CI 1.9-5.1). Based on this RR, the population attributable risk was 14.7% among workers with current asthma. These results suggest occupation contributes to approximately one in seven cases of severe exacerbation of asthma in a working population, and various agents play a role.

- ABSTRACT: BACKGROUND: The primary aim of the present study was to investigate if exposure to dust from absorbent hygiene products containing superabsorbent polymer is related to symptoms from the airways and from the eyes. The secondary aim was to estimate the current exposure to superabsorbent polymer among production and maintenance workers in a plant producing hygiene products. METHODS: The cohort comprised 1043 workers of whom 689 were exposed to super absorbent polymer and 804 were exposed to paper dust (overlapping groups). There was 186 workers not exposed to either superabsorbent polymer or to paper dust They were investigated with a comprehensive questionnaire about exposure, asthma, rhinitis and symptoms from eyes and airways. The results were analyzed with logistic regression models adjusting for sex, age, atopy and smoking habits. An aerosol sampler equipped with a polytetrafluoroethylene filter with 1 um pore size was used for personal samplings in order to measure inhalable dust and superabsorbent polymer. RESULTS: The prevalence of nasal crusts (OR 1.4, 95% CI 1.01-2.0) and nose-bleeding (OR 1.7, 95% CI 1.2-2.4) was increased among the paper dust exposed workers (adjusted for superabsorbent polymer exposure). There were no significant effects associated with exposure to superabsorbent polymer (adjusted for paper dust exposure). The average exposure to inhalable levels of total dust (paper dust) varied between 0.40 and 1.37 mg/m3. For superabsorbent polymer dust the average exposure varied between 0.02 and 0.81 mg/m3. CONCLUSIONS: In conclusion, our study shows that workers manufacturing diapers in the hygiene industry have an increased prevalence of symptoms from the nose, especially nose-bleeding. There was no relation between exposure to superabsorbent polymer and symptoms from eyes, nose or respiratory tract, but exposure to paper dust was associated with nose-bleeding and nasal crusts. This group of workers had also a considerable exposure to superabsorbent polymer dust.

- We have recently published a study on new-onset asthma in a large population in northern Europe using a modified job exposure matrix (N-JEM) to better reflect exposure assignment in these countries. The aim of this paper was to investigate how the N-JEM differs in exposure assignment and asthma risks from an already established JEM. The study comprised 6253 men and 7031 women from northern Europe, born 19451973, who had answered both a screening (19891992) and a follow-up questionnaire (19992001). During the study period (19802000), there were 136 men and 293 women with new-onset asthma. Hazard ratios of new-onset asthma were calculated for both JEMs using Cox regression models. The analyses were made separately for men and women and were also stratified for atopy. Cohens kappa () was used to show agreements in exposure assignment (yes/no) between the JEMs. Population attributable risks (PARs) were calculated as well. The agreement in exposure assignment between the JEMs was substantial for the group any exposure to asthma agents ( 0.78). The agreement between comparable exposure groups in the JEMs varied from 1.00 (pharmaceutical product antigens, textile dust, cleaning agents) to 0.27 (low molecular weight agents). Significant increased asthma risks were seen for men exposed to isocyanates and accidental peak exposure with both JEMs. With the N-JEM, increased asthma risks were seen for men exposed to plant-associated antigens (all and non-atopic), epoxy compounds (all and non-atopic), and acrylates (non-atopic). With the other JEM, increased asthma risks were seen in men and women exposed to possible exposure to irritant gases or fumes (all and non-atopic), a group classified as having low asthma risk. Men and women exposed to cleaning agents also showed significant asthma risks with both JEMs. PAR with the N-JEM was 14.3% for men and 6.6% for women, compared with 12.9% and 8.3% with the other JEM. Acrylates, epoxy compounds, and isocyanates are three exposure groups in the modified asthma JEM that might better reflect exposure situations in northern Europe than the already established JEM. Exposure to possible exposure to irritant gases or fumes, a low asthma risk group in the established JEM, seems to be a group with high asthma risk in northern Europe. It is important to continuously update JEMs, which are based only on occupational titles, in order to find new risk groups and to better reflect changes in work exposures when old risks disappear and new emerge.

- In a large population-based study among adults in northern Europe the relation between occupational exposure and new-onset asthma was studied. The study comprised 13 284 subjects born between 1945 and 1973, who answered a questionnaire 19891992 and again 19992001. Asthma was defined as Asthma diagnosed by a physician with reported year of diagnose. Hazard ratios (HR), for new-onset adult asthma during 19802000, were calculated using a modified job-exposure matrix as well as high-risk occupations in Cox regression models. The analyses were made separately for men and women and were also stratified for atopy. During the observation period there were 429 subjects with new-onset asthma with an asthma incidence of 1.3 cases per 1000 person-years for men and 2.4 for women. A significant increase in new-onset asthma was seen for men exposed to plant-associated antigens (HR 3.6; 95% CI [confidence interval] 1.49.0), epoxy (HR 2.4; 95% CI 1.34.5), diisocyanates (HR 2.1; 95% CI 1.23.7) and accidental peak exposures to irritants (HR 2.4; 95% CI 1.34.7). Both men and women exposed to cleaning agents had an increased asthma risk. When stratifying for atopy an increased asthma risk were seen in non-atopic men exposed to acrylates (HR 3.3; 95% CI 1.47.5), epoxy compounds (HR 3.6; 95% CI 1.67.9), diisocyanates and accidental peak exposures to irritants (HR 3.0; 95% CI 1.27.2). Population attributable risk for occupational asthma was 14% for men and 7% for women. This population-based study showed that men exposed to epoxy, diisocyanates and acrylates had an increased risk of new-onset asthma. Non-atopics seemed to be at higher risk than atopics, except for exposure to high molecular weight agents. Increased asthma risks among cleaners, spray painters, plumbers, and hairdressers were confirmed.
