Air pollution has been found to have adverse effects on human life at every stage, from foetal development to dementia, according to a report by the Environmental Research Group at Imperial College London. The review analysed over 35,000 studies from organisations including the World Health Organization, the UK Committee on the Medical Effects of Air Pollution, the Royal College of Physicians, the Health Effects Institute and the International Agency for Research on Cancer. The report found that air pollution could impact newborn health in the first weeks of life, leading to low birth weights, miscarriages and stillbirths. Pregnant women exposed to pollution could inhale particles that affect foetal development and alter blood flow. The report also found that exposure to air pollution could reduce sperm volume in men. Children exposed to air pollution could experience hampered lung growth, high blood pressure and cognitive and mental health issues. The report also linked air pollution to asthma, cardiac death, stroke risk and cardiovascular disease.
