Imagine a house. This house has floor boards that grew
mildewed due to the leak in the roof. This house has outlets without protectors
on them making it to easy to electrocute yourself. The cords to lights and electronics snake along
the floor near puddles of water from the leaks in the roof. The only thing that
remains beautiful about this house is the walls. Painted a soft baby blue and
still looking new after being there for years. In this house that is filled
with dangers the most hazardous thing is the beautiful blue wall. Why? You may
ask. Well the answer is the paint. It may not seem to be of a big concern, but
the blue paint that is so beautiful contains lead. Now you may be thinking that having lead in
paint isn’t a threat because it is used in the yellow lines in the street, or
heavy machinery, but just because we can’t see the danger of having paint that
contains lead in it, doesn’t mean that it isn’t just as harmful as having
unprotected outlets in a house. So why
is lead paint so dangerous?
On December 11, 2012
the Baltimore Press came out saying that a local store had to stop selling a certain
type of necklaces, earrings, and ring. The reason for this was because the Baltimore
City Health Department said that the small ring necklaces and earrings because
they contained lead levels above the 100 parts per million on a scale of 900 to
2,400 that was legally allowed. Lead
is a metal whose tarnish layer can be made up of carbonates and hydrox
carbonates. Lead contains the oxidation state +2 in this stage lead is pretty
basic. Lead also contains oxidation +4 which makes the lead more acidic. Lead
has a number of oxides in it which make up the different forms that lead can
come in. Lead is a navy metal like
mercury making it toxic when taken from the earth. Lead is a compound and an element. Lead has an
ionic bond. Metals and non-metals put together make up an ionic bond. Although
paint containing lead can cause real danger to our human bodies, it makes toys,
houses, and machinery look good. Having
lead in paint makes the paint bright, durable, flexible, and it is a very
inexpensive product. Different colors
of paint contain a different type of lead chromates. White lead mixed with yellow and a little
dark orange can enhance the yellow in paint, or give the paint an orange
hue. Lead paint has pigments have two
common forms. The first form is white lead which is a lead carbonate and the
other form is red lead which is a form of lead oxide. Lead pigments in paint
are very small making it easy to spread across a bigger surface. When in its elemental form lead is a bluish
white lustrous metal. But when found in paint it is in an ionic form and its
properties dramatically change. The
isotopes in lead are the ending product of each of the three series of
radioactive elements that naturally occur.
To this day about 24 million houses in the United States
that were made before the year 1978 still have paint that contains lead in it.
This fact means that having young kids and adults live in these houses is very
unsafe. Lead dust from the paint on the
inside or the outside of a home can cause brain and nervous system damage. It
can also cause behavior and learning problem, hyperactivity, slowed growth
hearing problems, and headaches. It
isn’t easy to tell regular paint from paint that contains lead though, and
that’s what makes it even more hazardous. When a person ingests lead, the lead
takes away the zinc that we have in our bodies that helps the oxygen flow in
our blood. Zinc keeps out high amounts of copper that our body can absorb and
causes growth in our bodies. If zinc is taken out of our blood stream then our
bodies become unprotected. Zinc protects the immune system and other important
organs. When lead gets into our bodies it takes away the zinc and can ruin the
immune system and nervous system. All of the aspects that make lead paint seem
so easy and cheap to use, should not compare to the fact the using lead in
paint can harm a person for the rest of their lives. Dr. Oxiris Barbot who is a commissioner
of health stated to the Baltimore Times that “we should take out toys that have
lead paint in them because the cost of lead poisoning can last a life time. Even
though we can’t see lead making it hard for us to know if it exists in our
homes, there are ways to test your homes for lead paint. A good website to look at for more information
on how to test for lead paint in our bodies and homes is the EPA website.
