World Trade Centre explosion

World Trade Centre explosion - The so-called ‘War on Terrorism’ the United States are fighting in Asia currently all started with the event we recall so well from the shocking images projected on news bulletins. On September 11, 2001, terrorists flew airplanes into the buildings of the World Trade Centre. It is now claimed that the attack and simultaneous collapse of the Twin Towers caused a serious and acute environmental disaster.

"We will live in the death smog for a while,
breathing the dust of the dead,
the 3 thousand or so who turn to smoke,
as the giant ashtray in Lower Manhattan
continues to give up ghosts.
The dead are in us now,
locked in our chests,
staining our lungs,
polluting our bloodstreams.
And though we cover our faces with flags
and other pieces of cloth to filter the air,
the spirits of the dead aren’t fooled
by our masks." Lawrence Swan, 05-10-2001

As the planes hit the Twin Towers more than 90.000 litres of jet fuel burned at temperatures above 1000oC. An atmospheric plume formed, consisting of toxic materials such as metals, furans, asbestos, dioxins, PAH, PCB and hydrochloric acid. Most of the materials were fibres from the structure of the building. Asbestos levels ranged from 0.8-3.0% of the total mass. PAH comprised more than 0.1% of the total mass, and PCBs less than 0.001% of total mass. At the site now called Ground Zero, a large pile of smoking rubble burned intermittently for more than 3 months. Gaseous and particulate particles kept forming long after the towers had collapsed.

The day of the attacks dust particles of various sizes spread over lower Manhattan and Brooklyn, for many miles. Fire fighters and medics working at the WTC were exposed, but also men and women on the streets and in nearby buildings, and children in nearby schools. In vivo inhalation studies and epidemiological studies pointed out the impact of the dust cloud. Health effects from inhaling dust included bronchial hyper reactivity, because of the high alkalinity of dust particles. Other possible health effects include coughs, an increased risk of asthma and a two-fold increase in the number of small-for-gestational-age baby’s among pregnant women present in or nearby the Twin Towers at the time of the attack. After September, airborne pollutant concentrations in nearby communities declined.

Many people present at the WTC at the time of the attacks are still checked regularly, because long-term effects may eventually show. It is thought there may be an increased risk of development of mesothelioma, consequential to exposure to asbestos. This is a disease where malignant cells develop in the protective cover of the body’s organs. Airborne dioxins in the days and weeks after the attack may increase the risk of cancer and diabetes. Infants of women that were pregnant on September 11 and had been in the vicinity of the WTC at the time of the attack are also checked for growth or developmental problems.
