In arriving at the decision contained in its latest report on Global Urban Ambient Air Pollution, the World Health Organisation (WHO) stated that a study of water pollution in Onitsha, found high levels of arsenic, mercury, lead, copper and iron in its water. It also found more than 100 petrol stations in the city selling low-quality fuel, with attendant fuel spills and many rubbish dumps in the state. It noted that the city’s metal industries, private hospitals, workshops and residents were heavy polluters, emitting chemical, hospital and household waste and sewage. An environmentalist, Chike Okoronkwo, agreed that Onitsha could be experiencing the problem “because most industries there run on generating plants, which generate a great deal of carbon monoxide. There is also so much congestion in the city, with even household waste littering everywhere. The worst is the fact that residents have no idea of how to dispose and manage the refuse they generate.”
The vast hole in the ozone layer above Antarctica appears to be healing, scientists say, putting the world on track to eventually remedy one of the biggest environmental concerns of the 1980s and 90s. Research by US and UK scientists shows that the size of the ozone void has shrunk, on average, by around 4m sq km since 2000. The measurements were taken from the month of September in each year, when the ozone hole starts to open up each year.
well done Izucals!
