Pressure
treated lumber is a specialized greenish color
wood which is treated with special preservatives
to make it last longer. The specially designed
lumber effectively counters the attack of fungus,
insects and moistures and guarantees a much better
life in comparison to other woods. The whole process
of pressure treated lumber is very interesting
starting with making minute cuts in the piece of
lumber, which is then put in a specialized cylinder.
Inside the cylinder pressure is created to suck
moisture from the piece and then the powerful pressure
pushes the whole moisture to concentrate in the
first centimeter of the wood. Finally the piece
is dried naturally under the heat of sunlight.
The resistance capacity of pressure treated
lumber increases five times in comparison to
the normal wood due to preservatives used to
get its productive life increased.
Pressure Treated Lumber Health Risk
Two known chemicals arsenic and chromium are
used to treat the pressure treated lumber. Arsenic
is hazardous to the body because if the poisonous
substance contained in it enters into the body
it causes cancer or skin irritation. Similarly
chromium copper arsenate has negative effects
on the body if remain exposed for long. Thus
chromium copper arsenate in the wood leads to
an irritation of skin and moreover with both
the chemicals having an ability to get absorbed
in the surrounding soil prove further hazardous
to the user.
These days pressure treated lumber is extensively
used in making school furniture like school desks,
fences etc that prove very hazardous for school
children and adults. In the early nineties it
has been revealed by the government studies that
in comparison to concrete wood people working
exclusively on pressure treated lumber suffer
more from dermatitis. Continuous exposure to
these metals cause diseases like carcinogenic
irritation, damaged liver, digestive problems,
breathing problems and even chromosome damage
in men and women. Thus the pressure treated lumber
along with long durability brings many hazardous
diseases making an extensive use of the lumber
think again.
