HOW GENERATOR FUMES RAISE CANCER, SUDDEN DEATH RISK, OTHERS, BY EXPERTS


AS electricity generating sets become must-have household items in most Nigerian homes due to epileptic power supply, their use, sometimes round-the-clock with the attendant noise and air pollution, has been associated with the growing cases of cancers, premature birth, low weight babies and childbirth complications such as neo-natal jaundice and cerebral palsy.
Newborn jaundice is when a baby has high levels of bilirubin in the blood. Bilirubin is a yellow substance that the body creates when it replaces old red blood cells. The liver helps break down the substance so it can be removed from the body in the stool.
High levels of bilirubin make the baby’s skin and whites of the eyes look yellow. This is called jaundice. High levels of bilirubin - usually above 25 mg - can cause deafness, cerebral palsy, or other forms of brain damage in some babies.

Cerebral palsy is a group of disorders that can involve brain and nervous system functions, such as movement, learning, hearing, seeing and thinking.
A recent study by Nigerian researchers at the University of Lagos (UNILAG) concluded: “The data available from this study shows that generator fumes contribute significantly to the atmospheric level of Polynuclear Aromatic Hydrocarbons (PAHs) and that the level is dependent on the distance from the point of generation. This suggests significant risk of cancer to the population in an environment where the use of generator is commonplace. Considering the lipophilicity of PAHs, small concentrations can accumulate over a long period of time.
“…The control group had no 1-hydroxypyrene in their blood. After the period of exposure, percentage of death correlated with the distance from the source of exposure. Percentage of death ranged from 56 per cent to zero depending on the proximity to source of pollution.”
The study published in Biomarkers in Cancer is titled “1-Hydroxypyrene Levels in Blood samples of Rats After exposure to Generator Fumes.”
The researchers from departments of pharmaceutical chemistry and biochemistry were led by Dr. Chimezie Anyakora. The other researchers include: Clinton Ifegwu, Miriam Igwo-ezikpe, Akinniyi Osuntoki, Kafayat A. Oseni and Eragbae O. Alao.
PAHs are a major component of fuel generator fumes. Carcinogenicity of these compounds has long been established.
The researchers exposed 37 Swiss albino rats to generator fumes at varied distances for eight hours per day for a period of 42 days and the level of 1-hydroxypyrene in their blood was evaluated. The study also correlated the level of blood 1-hyroxypyrene with the distance from the source of pollution.
Also, researchers have warned that exposure to air pollution could trigger potentially fatal pre-eclampsia in pregnant women.
According to a new study published in BMJ Open, women with asthma are particularly vulnerable to the condition - marked by high blood pressure and fluid retention. It blamed one in every 20 cases of pre-eclampsia on higher levels of ozone pollution in the air during the first three months of pregnancy, as well as an increase in premature births.
The only treatment is to deliver the baby early with an emergency Caesarean.
The new study adds to evidence of a link between air pollution and premature birth, with international research earlier this week showing higher pollution levels raised the risk of low birth weight.
Another study found that heavy traffic fumes could increase risk of having a small baby and that particles that are affecting pregnant mothers mainly come from the burning of fossil fuels.
