Suberosis at Public Health Unit (PHU) of Santa Maria da Feira/Arouca (F/A) (Portugal)

Introduction Santa Maria da Feira (SMF) is currently one of the largest producers of cork in Portugal. Suberosis is an occupational disease of workers in the cork processing industry, associated with repeated exposure to moldy cork dust, usually presenting itself as a disease of the pulmonary interstitium (Hypersensitivity Pneumonitis). This study aims to assess the impact of occupational health interventions on the cork industry, in terms of health promotion and risk prevention. Methods We assessed 10 different cork companies distributed in 10 parishes of SMF. Results With regard to health promotion, we highlight the development of healthy workplaces and the strong commitment to training health professionals with regard to the correct use of personal protective equipment (PPE). Regarding the prevention of risks, emphasis is placed on the two areas that imply greater professional risks: storage and the process of drilling and boring. The storage of cork is done most of the time in dark and humid places, providing ideal conditions for the development of mold and the process of drilling and boring exposes workers to large amounts of moldy cork dust. In these settings, investing in PPE namely protective gloves and mask, as well as collective prevention measures, namely effective ventilation systems and regular control of humidity conditions, are essential to health protection of workers. Conclusions SMF has a prevalence of Suberosis well above the national average. In order to respond to this issue, the cork industry must reinforce the investment in terms of PPE, with the use of uniform, cuffs, safety shoes and visor, variable with the specific production process. In terms of collective protection, the signaling of the main hazards and the information available in the workstations regarding mandatory/recommended PPE, isolation of the areas with the most dangerous tasks as well as the maximum possible turnover between tasks are essential in terms of Occupational Health. Key messages Suberosis is an occupational disease of workers in the cork industry, associated with repeated exposure to moldy cork dust, usually presenting itself as a disease of the pulmonary interstitium. The development of healthy workplaces, the correct use of PPE and the investment in effective ventilation systems and control of humidity, are essential to health protection of cork workers.

Comparison between a Traditional (Horse Manure) and a Non-Conventional (Cork Powder) Organic Residue in the Uptake of Potentially Toxic Elements by Lettuce in Contaminated Soils

The use of natural organic correctives is a current agricultural practice that may have advantages for the production of plants in contaminated soils. Cork powder is a natural sub-product of the cork industry that has several potential benefits compared to more commonly used soil amendments. In this work, an evaluation was performed of the use of cork powder (a non-conventional organic residue) and horse manure (traditionally used in agriculture) to control the availability of potentially toxic elements in artificially contaminated soils. Four concentrations were used for each element: Cr (100 to 800 mg kg−1), Ni (37.5 to 300 mg kg−1), Zn (150 to 1200 mg kg−1), Cd (1.5 to 12 mg kg−1) and Pb (150 to 1200 mg kg−1). The accumulation of these elements in lettuce plants grown in pots under controlled conditions was evaluated. With the exception of Cd, no significant differences were detected in the absorption of the different elements by lettuce plants at the studied amounts of correctives applied (1% for cork powder and 0.5% for horse manure). Cadmium was the element that accumulated most in lettuce. Cork powder was shown to be less effective than horse manure in controlling the bioavailability of these elements in the soil. Further tests with chemically modified cork products could improve its efficiency.

Biochemical Methane Potential of Cork Boiling Wastewater at Different Inoculum to Substrate Ratios

The present study evaluates the digestion of cork boiling wastewater (CBW) through a biochemical methane potential (BMP) test. BMP assays were carried out with a working volume of 600 mL at a constant mesophilic temperature (35 °C). The experiment bottles contained CBW and inoculum (digested sludge from a wastewater treatment plant (WWTP)), with a ratio of inoculum/substrate (Ino/CBW) of 1:1 and 2:1 on the basis of volatile solids (VSs); the codigestion with food waste (FW) had a ratio of 2/0.7:0.3 (Ino/CBW:FW) and the codigestion with cow manure (CM) had a ratio of 2/0.5:0.5 (Ino/CBW:CM). Biogas and methane production was proportional to the inoculum substrate ratio (ISR) used. BMP tests have proved to be valuable for inferring the adequacy of anaerobic digestion to treat wastewater from the cork industry. The results indicate that the biomethane potential of CBWs for Ino/CBW ratios 1:1 and 2:1 is very low compared to other organic substrates. For the codigestion tests, the test with the Ino/CBW:CM ratio of 2/0.7:0.3 showed better biomethane yields, being in the expected values. This demonstrated that it is possible to perform the anaerobic digestion (AD) of CBW using a cosubstrate to increase biogas production and biomethane and to improve the quality of the final digestate.

Suberose- a Doença Profissional mais Portuguesa

Introduction/ background/ objectives Portugal is the world’s largest producer of cork. It is derived from the cork oak (quercus suber) and consists of dead cells with cellulose. The tasks with the highest load are usually assigned to the male and the most repetitive to the female; this implies a different occupational exposure, meaning that exposures of higher risk generally occur almost exclusively in male positions. The first reference to Suberose (cork = suber) was in 1947. However, most studies in the sector were carried out in companies with good working conditions, so the conclusions may not be easily extrapolated to most cork workers. The aim of this bibliographic review is to summarize the most relevant information about the topic. Methodology This is a Bibliographic Review, initiated through a survey conducted in October 2020 in the databases “CINALH plus with full text, Medline with full text, Database of Abstracts of Reviews of Effects, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Cochrane Methodology Register, Nursing and Allied Health Collection: comprehensive, MedicLatina and RCAAP ”. Content The first articles related to the Cork sector highlight the role that some microorganisms have, like Penicillium glabrum (formerly known as frequentans); more recent documents add Chrysonilia Sitophila and Mucor. In places with less humidity the fungal concentration decreases. Workers with Suberosis had skin reactions to the fungus in question and the inhalation of the respective aerosols caused the characteristic symptoms. Some authors also believe that some mites may have some relevance in cork asthma (such as P notatum, Cladosporium, A fumigatus, Alternaria alternata, Acarus siro and Tyrophagus putrescentiae). The suberin found abundantly in cork, may also be associated with some symptoms. Workers are also exposed to cork dust; yet it is less prevalent in the workplace than fungi. Suberose is a pathology of the pulmonary interstitium caused by repeated exposure to dust and mold from cork; in fact, it is the most prevalent disease of the pulmonary interstitium in the north of the country. However, Asthma may also be associated with a lower prevalence. Depending on the size of the fungal spores, Asthma or Hypersensitivity Pneumonitis will be more likely, that is, if smaller (1 to 2 micromers), an alveolar response (alveolitis) will appear more frequently; if larger, a bronchial response, like asthma, can occur. Conclusions The cork industry is reasonably developed in some areas of the country, but knowledge about Suberosis is not always abundant. It would be relevant that all professionals in the Occupational Health Teams with clients in this area were comfortable in the way how to approach the sector; in addition, it is very relevant to develop recent research, disseminating it internationally, not least because Portugal is the country that most developed the sector, worldwide.

Finding Value in Wastewaters from the Cork Industry: Carbon Dots Synthesis and Fluorescence for Hemeprotein Detection

Valorisation of industrial low-value waste residues was preconized. Hence, carbon dots (C-dots) were synthesized from wastewaters of the cork industry—an abundant and affordable, but environmentally-problematic industrial effluent. The carbon nanomaterials were structurally and morphologically characterised, and their photophysical properties were analysed by an ensemble of spectroscopy techniques. Afterwards, they were successfully applied as highly-sensitive fluorescence probes for the direct detection of haemproteins. Haemoglobin, cytochrome c and myoglobin were selected as specific targets owing to their relevant roles in living organisms, wherein their deficiencies or surpluses are associated with several medical conditions. For all of them, remarkable responses were achieved, allowing their detection at nanomolar levels. Steady-state and time-resolved fluorescence, ground-state UV–Vis absorption and electronic circular dichroism techniques were used to investigate the probable mechanisms behind the fluorescence turn-off of C-dots. Extensive experimental evidence points to a static quenching mechanism. Likewise, resonance energy transfer and collisional quenching have been discarded as excited-state deactivating mechanisms. It was additionally found that an oxidative, photoinduced electron transfer occurs for cytochrome c, the most electron-deficient protein. Besides, C-dots prepared from citric acid/ethylenediamine were comparatively assayed for protein detection and the differences between the two types of nanomaterials highlighted.
