Fumes from cleaners, kerosene heaters and aerosol cans are equally dangerous. The air your birds share with you and your family is a highly efficient catalyst for transmitting zoonotic diseases to people and other animals. Dust from feathers and dried feces not only creates a cleaning problem, but It also harbors and feeds disease-causing organisms that can attack people and birds. Dust and dander from birds are linked to many respiratory infections, including bird fancier lung. It is interesting to note that most of the pollutants are organic in nature and that the chemicals we consider to be problems exist all around us in nature, where they are not considered problems, To become a problem, the dosage must be such that adverse effects result.
Dosage is, f course, a function of both concentration and time of exposure.
Even small amounts of pollutants will cause adverse effects if the duration of exposure is long enough. These adverse effects occur so gradually that they are not associated with their true cause. They established that the loss of these elements could cause building occupants to complain of headaches, weakness and a generally unwell feeling. As part of the study, researchers leaned that after five months of testing that a feeling of well being returned to those exposed to an ozone level of .015 ppb. At these same levels they were able to observe increased immune potential, higher oxygen content in the blood, improved blood pressure readings and the reduction of many stress characteristics associated with modern indoor environments.
