Link between mould growth and development of asthma and allergy questioned


A recent study carried out at the Norwegian University of Science and Technology suggests that there is no link between mould-spore concentrations in indoor air and the development of asthma and allergy in children. Many studies have found that moisture-related problems in building increase the instance of  respiratory problems and allergy in children and adults, but it has been thus far unclear as to what agents in the air or dust have caused the problems.  The study suggests a different approach on how to recognise the mould growths and how they might link to health problems in humans. Other agents could include chemicals and phthalates, and researcher Jonas Holme advocates more study on corrective measures to reduce indoor environmental problems. There may be a link between moisture problems in buildings and types of ventilation – more cases of mould have been found in houses with no ventilation or natural ventilation than in those with mechanical ventilation.
