Las autoridades estadounidenses emitieron el viernes la recomendación de desmontar unas 3.000 viviendas afectadas por la contaminación de placas de yeso importadas desde China.
El Departamento de Vivienda y Ciudad y la Comisión de Seguridad de Productos de Consumo estadounidenses recomendaron no sólo quitar las placas en cuestión, sino además "reemplazar los cables eléctricos, las tuberías de gas, los sistemas de riego antiincendio y las alarmas de incendio y de monóxido de carbono".
En noviembre, autoridades sanitarias habían establecido formalmente un vínculo entre estas placas de yeso y la contaminación del aire con sulfuro de hidrógeno, emitido en cantidad cien veces superior a lo normal debido a una elevada concentración de sulfuro en este producto.

CBS/ AP) Thousands of U.S. homes tainted by Chinese drywall should be gutted, according to new guidelines released Friday by the Consumer Product Safety Commission.
The guidelines say electrical wiring, outlets, circuit breakers, fire alarm systems, carbon monoxide alarms, fire sprinklers, gas pipes and drywall need to be removed.
"We want families to tear it all out and rebuild the interior of their homes, and they need to start this to get their lives started all over again," said Inez Tenenbaum, chairwoman of the federal agency charged with making sure consumer products are safe.
The CBS News investigative unit first reported last year about the thousands of Americans forced out of their homes by defective, rotting drywall. But the investigative unit also found that there maybe be problems with American-made drywall.
About 3,000 homeowners, mostly in Florida, Virginia, Mississippi, Alabama and Louisiana, have reported problems with the Chinese-made drywall, which was imported in large quantities during the housing boom and after a string of Gulf Coast hurricanes.
The drywall has been linked to corrosion of wiring, air conditioning units, computers, doorknobs and jewelry, along with possible health effects. Tenenbaum said some samples of the Chinese-made product emit 100 times as much hydrogen sulfide as drywall made elsewhere.
The agency continues to investigate possible health effects, but preliminary studies have found a possible link between throat, nose and lung irritation and high levels of hydrogen sulfide gas emitted from the wallboard, coupled with formaldehyde, which is commonly found in new houses.
U.S. Sen. Bill Nelson, D-Fla., said now the question is who pays to gut the homes.
"The way I see it, homeowners didn't cause this. The manufacturers in China did," Nelson said. "That's why we've got to go after the Chinese government now."
Southern members of Congress have sought to make it easier to sue Chinese manufacturers and to get the Federal Emergency Management Agency to help homeowners pay for costs not covered by insurance. They also say the U.S. needs to pressure the Chinese government, which allegedly ran some of the companies that made defective drywall.
About 2,100 homeowners have filed suit in federal court in New Orleans against Chinese manufacturers and U.S. companies that sold the drywall. U.S. District Judge Eldon Fallon is expected to rule soon in a pivotal case against the Knauf Plasterboard Tianjin Co., the only Chinese company that has responded to U.S. suits.
Separate claims by thousands more homeowners against Chinese manufacturers are pending, said Jordan Chaikin, a Florida lawyer whose firm represents about 1,000 homeowners.
They are "continuing to live in their homes with Chinese drywall, patiently waiting for this thing to be resolved so they can move on with their lives," Chaikin said. "We're not waiting for the government to move quicker than we are in the courts."
In some cases, homebuilders have paid to gut and rewire homes. In others, homeowners who can afford it have paid for the work themselves. Knauf Plasterboard has offered to pay for remediation in homes where its defective drywall was installed.
Si bien China asoma como la futura segunda o primera gran potencia, los problemas vinculados a la calidad de su producción están profundamente vinculados a sus posibilidades reales: su desarrollo actual le exige cambiar las condiciones en que sus manufacturas se venden, y este cambio implica radicales modificaciones en las bases sobre las que se asienta su desarrollo industrial y su modelo de negocios. Estos cambios tenderán sin duda a disminuír su ventaja comercial actual.
