health risks from plastic water pipes

by:ER Bottle     2020-01-17
Plastic water pipes have been the preferred material for plumbers and home builders since the 1950 s.
Plastic pipes are usually made of PVC, which is easy to install and affordable (PVC)
PVC chloride (CPVC)
Juzheng (PB).
Safety issues surrounding these materials have led to the development of alternative materials such as high
Density Polyethylene (HDPE)and cross-
Link polyethylene (PEX).
PVC research published in the Journal of Environmental Engineering found that in houses built before 1977, it is found that the installed PVC pipe filters PVC into drinking water at a level higher than the maximum allowable pollutant level.
Tested the level at death.
The end pipe segment of water stagnation.
To reduce concentration, it is recommended to install a manual or automatic flushing valve.
Centers for Disease Control (CDC)
Note that PVC contains neighboring benzene ester that can be dissolved from plastic, and in animal studies it demonstrates the ability to cause liver and reproductive system damage.
The Centers for Disease Control and Prevention warned
Long-term exposure to neighboring benzene Ester has little toxicity to adults;
Animal studies have shown that continuous exposure to neighboring benzene Ester is toxic even at low doses.
Especially for babies, phthal salts are not treated well.
New plastic pipe parts are marked to meet current standards for drinking water.
Pipes that meet the requirements are stamped with the NSF-PW or NSF-
61. ensure that these pipelines meet the national standards association of the United States (ANSI)
Standard for drinking water or drinking water.
This standard evaluates contaminants or impurities in materials in contact with drinking water.
The manufacture and treatment of PVC will produce strong environmental toxins.
The main component of PVC pipe PVC is classified as known human carcinogens.
The stabilizer and plasticizer used in PVC production may contain lead or other heavy metals and during incineration-
A common way of disposal
Release hydrochloric acid.
Hydrochloric acid is corrosive and can cause damage to the respiratory system.
In building fires, this is also a problem, exposing firefighters to burning PVC can put them at risk.
According to the Institute for Global Development and Environment at the University of taffz, as many as 70% of households in the United States have PVC pipes.
Many communities are moving away from PVC pipes and instead choose to use high density polyethylene or PEX.
