Mining is a vital sector for many African countries, providing raw materials, jobs, and revenues. But mining also has significant impacts on the environment and the people living near the mines. How can we balance these trade-offs and ensure that mining contributes to sustainable development in Africa? One of the main challenges is to align …
Sulfur dioxide (SO2) is a harmful air pollutant that can cause respiratory problems, acid rain and environmental damage. It is mainly emitted from the burning of fossil fuels by power plants and other industrial facilities. In this post, I discuss how industries use various methods to remove SO2 from their emissions and what are the …

Hydrogen is the most abundant element in the universe, but it is not readily available on Earth as a pure gas. It has to be extracted from water or other compounds using energy. Hydrogen has been known as a potential fuel since the 18th century, when it was first isolated by Henry Cavendish and named …

Microplastics found embedded in fat and lungs of seals, dolphins and whales Despite improvements, wastewater treatment plants allow novel pollutants such as active ingredients from pharmaceuticals and personal care products, pesticides and organic pollutants to escape to water systems. Danish scientists estimate the biodiversity of mammals, birds and amphibians in a forest by sampling DNA …
Air pollution is one of the major environmental challenges of our time, affecting millions of people around the world. According to the World Health Organization (WHO), air pollution is responsible for an estimated 7 million premature deaths every year, mainly due to exposure to fine particles that penetrate deep into the lungs and cardiovascular system. …

Global warming is the increase in the average temperature of the Earth’s surface and atmosphere due to the accumulation of greenhouse gases, such as carbon dioxide, methane, and nitrous oxide, in the air. These gases trap heat and prevent it from escaping to space, causing the planet to warm up. Human activities, especially the burning …

Risk of the hydrogen economy for atmospheric methane. Leaking hydrogen infrastructure could add to atmospheric methane levels. Increased levels of ozone from atmospheric pollution can destroy the chemical mating signal of insects and may thus contribute to global insect decline. Microbial biopesticides containing living parasites are valuable emerging crop protection technologies against insect pests, but …
