  8. Invasive Alien Species What is an Invasive Alien Species? An alien species is a species introduced by humans - either intentionally or accidentally - outside of its natural past or present distribution. Not all alien species have negative impacts, and it is estimated that between 5% and 20% of all alien species become problematic. These are termed invasive alien species' (AS). An invasive alien species is both non-native to the ecosystem in which it is found and capable of causing environmental, economic, or human harm because of its ability to spread rapidly and compete with native species. This means that not all alien species are considered invasive. It is also possible for a species to be invasive in one ecosystem but not in another. Invasive species are often successful in their new ecosystems because they can reproduce and grow rapidly or because their new environment lacks any natural predators or pests. CAyussh Sanghi's MCQ DIGEST

  9. Invasive Alien Species What are their impacts? Invasive alien species are a major driver of biodiversity loss. In fact, an analysis of the IUCN Red List shows that they are the second most common threat associated with species that have gone completely extinct, and are the most common threat associated with extinctions of amphibians, reptiles and mammals. Invasive alien species can also lead to changes in the structure and composition of ecosystems leading to significant detrimental impacts to ecosystem services, affecting economies and human wellbeing. What are naturalised species? In biology, naturalisation is any process by which a non-native organism or species spreads into the wild and its reproduction is sufficient to maintain its population. Such populations are said to be naturalised. Naturalised species, unlike invasive species, reproduce naturally in the environment. CAyussh Sanghi's MCQ DIGEST

  12. Arsenic Contamination of Groundwater . Arsenic contamination is understood to be of geogenic origin released from soil under conditions conducive to dissolution of Arsenic from solid phase on soil grains to liquid phase in water. It does not owe its origin to overuse of fertilisers Despite a number of corrective and precautionary measures, the spread of Arsenic contamination in groundwater continued to grow and more new areas were added to the list of contaminated area. . Arsenic is highly toxic in its inorganic form. Long-term exposure to arsenic from drinking-water and food can cause cancer and skin lesions. It has also been associated with cardiovascular disease and diabetes. In utero and early childhood exposure has been linked to negative impacts on cognitive development and increased deaths in young adults. CAyussh Sanghi's MCQ DIGEST
