Lipopolysaccharide (LPS) is an essential component of the outer membrane in most Gram-negative bacteria. LPS consists of the lipid A moiety linked to a short-core oligosaccharide and the distal Oantigen polysaccharide chain. The most biologically active component of LPS is lipid A (or endotoxin), a strong activator of monocytes to release immune stimulators such as proinflammatory cytokines. LPS and lipid A can be present on the bioaerosol at different workplaces causing different endotoxic diseases.

New automated technologies in environmentally sensitive shipyards

Shipbuilding industry is known as one of the hardest metal industry with several chemicals and hazardous material. Most of the production processes such as welding, painting, blasting and fiberglass production have direct impact on workers health. There are several wastes and pollutants being released during shipbuilding and ship repairing processes.

Personal protective equipment to minimize the shipyard production processes health effects on shipyard workers

Production processes of shipyards are divided into two main divisions under new shipbuilding and ship repair industry. The shipbuilding and ship repair industry is the combination of different production processes such as surface preparation, painting and coating, machining and metalworking operations, solvent cleaning and degreasing, welding and cutting operations. The inputs of these processes are various types of products and raw material such as primarily steel and other metals, paints and solvents, blasting abrasives, and machine and cutting oils.

Potential of selected metals to cause Metal Fume Fever: a comprehensive review
© Aristotle University of Thessaloniki (6/2009)
Metal fume fever (MFF) is a disease as old as the metallurgy of brass. It is an industrial acute illness of short duration that occurs when metals are heated above their melting point. It is most common to people with no previous exposure to the fumes or in workers returning to industrial environment after weekend. The disease is a constellation of symptoms, which may include metallic taste, cough, sneezing and tightness of chest, sweating, headache, fever, muscle aches, mouth dryness, nausea, vomiting, leykocytosis and tiredness. It is believed that the disease has an immunopathological basis facilitated by cytokines. The present paper highlights the mechanisms of MFF through the most relevant in vivo and in vitro experiments. Furthermore, each candidate metal is examined in relation to MFF provocation potential.
