MORE than 40 sites across Iraq are contaminated with high levels of radiation and dioxins, with three decades of war and neglect having left environmental ruin in large parts of the country, an official Iraqi study has found.

Areas in and near Iraq's largest towns and cities, including Najaf, Basra and Falluja, account for around 25 per cent of the contaminated sites, which appear to coincide with communities that have seen increased rates of cancer and birth defects over the past five years.

The joint study by the environment, health and science ministries found scrap metal yards in and around Baghdad and Basra contain high levels of ionising radiation, which is thought to be a legacy of depleted uranium used in munitions during the first Gulf war and since the 2003 invasion.

The environment minister, Narmin Othman, said high levels of dioxins on agricultural lands in southern Iraq, in particular, were increasingly thought to be a key factor in a general decline in the health of people living in the poorest parts of the country.

“If we look at Basra, there are some heavily polluted areas there and there are many factors contributing to it,” he told the Guardian. “First, it has been a battlefield for two wars, the Gulf war and the Iran-Iraq war, where many kinds of bombs were used. Also, oil pipelines were bombed and most of the contamination settled in and around Basra.

“The soil has ended up in people's lungs and has been on food that people have eaten. Dioxins have been very high in those areas. All of this has caused systemic problems on a very large scale for both ecology and overall health.”

Government study groups have recently focused on the war-ravaged city of Falluja, west of Baghdad, where the unstable security situation had kept scientists away ever since fierce fighting between militants and US forces in 2004. “We have only found one area so far in Falluja,” Othman said. “But there are other areas that we will try to explore soon with international help.”

The Guardian reported in November claims by local doctors of a massive rise in birth defects in the city, particularly neural tube defects, which afflict the spinal cords and brains of newborns.
