Ozone (O3) as mentioned in our previous blog post is one of the more prevalent air pollutants in our atmosphere. It is formed when Nitrogen oxides and volatile organic compounds (VOCs) from industrial sources or vehicle exhausts enters the atmosphere, and are transformed under photochemical reactions (through heat and sunlight). Ozone is a strong oxidizing…

How pollutants enter each of the different spheres are often not in isolation of each other, and as mentioned before…

With the basics of what forests are and why they are important, today we will be taking a deeper look into how forests are polluted. Some pollutants are naturally occurring – for example: weathering and abrasion of rocks, volcanic eruption, forest fires, and aerosol formation are responsible for the production of heavy metals within the…

Forests are land dominated by trees, in addition to being habitats for a plethora of biodiversity, they provide a range of ecosystem services for humans (as mentioned in previous blog posts). For example, these trees are photosynthetic organisms that produce the essential oxygen for the respiration of all living things on earth. Trees also help…

According to the Food and Agriculture Organization, forests are land of more than 0.5 hectares with trees taller than 5 meters and a canopy cover of 10% and more. Agricultural or urban land with these characteristics are not considered forests (Food and Agriculture Organisation, n.d.). There are different types of forest in this world, characterised…

Welcome back! Today, we will be talking more about pollution… one of the many buzzwords that are thrown around as environmental consciousness has started picking up as a hot topic for debate in the world.
