For the past few centuries, the growing industrial prowess of the world has introduced new and more dangerous toxins, chemicals, and heavy metals into the many water sources the Earth has to offer. As time goes, these pollutants can accumulate to threaten the health of humans and the wildlife they share the Earth with. While there are methods to remove these pollutants, they are often too expensive to use in the areas that need it the most. However, recent studies done by Progessor Gustavo Ferriera Coelho might show signs of hope. His effort is one that looks for alternate methods to reach problem-free water. One of these methods is biosorption. Biosorption is a natural process in which tropical plants, using biological operations to suck up contaminants, eradicating them in a rather effective manner.
The increased use of certain fertilisers has led to a growing amount of heavy metals in soil, such as aluminium, arsenic, copper and zinc (among others). This metal presence can lead to water pollution, which in turn can cause a myriad of health problems including hypertension, kidney failure, and skin aggravations. Heavy metals can bind to important cellular components, such as structural proteins, enzymes, and nucleic acids, and interfere with their functioning. Jatropha curcas is a perennially-flowering plant which flourishes in tropical conditions, making it an ideal choice for somewhere like Malaysia. Experts are optimistic that the tropical plants can provide a cheap, naturally-occurring and sustainable alternative to the more expensive and time-consuming methods currently deployed. This would allow water to be safely treated in remote and impoverished areas, thus granting everyone all over the world access to clean drinking water.
