The potential health hazards of exposure to house dust come
either from particulate matters and adsorbed semivolatile
compounds, which become resuspended again. This research
aimed to study the loss on ignition (LOI)
of settled dust in two differ
ent houses in Homs city during a year,
The settled dust samples were collected by vacuum cleaner once a
week, Then the samples were sieved and the LOI values were
calculated.
The maximum and minimum values of LOI were obtained in
addition to monthly mean and median values.
Upon the results of this research some suggestions were made to
improve the public health.
- The objective of this study was to assess the level of air
contamination by bacteria in the broiler houses in salamieh region
that Famed of commercial breedings of broiler and relationship
with some impact factors like (birds age- season-breedin
g system -
dust concentration) .
- The numbers of bacteria (mesophile , staphylococci , streptococci
and gram-negatives) and dust concentration were determined in 5
opened broiler houses and 5 closed broiler houses with chicken
houses in different ages (1-6 weeks old) in summer and winter .
The objective of the study was to determine experimentally
the dust pollution of polyethylene pipe during head- to - head
welding in the workshops piping and its impact on the efficiency of
welding.
