Corrosion and Corrosion Protection of Unio in Carbonic Acid Medium
Abstract: Unio is a calciferous animal, and its outer surface is made of calcium carbonate. It usually happens in sources of sweet water. They create carbonic acid by absorbing carbon dioxide. It changes the pH of sweet water sources thus water becomes acidic. It develops corrosive environment for Unio. Carbonic acid interacts with Unio to form corrosion cells on the interface of Unio. This acid oxidizes calcium carbonate into calcium ions …

Environmental Pollutants and Biodiversity Loss: Analyzing the Role of Persistent Organic Pollutants in Ecosystem Decline
Abstract: Persistent Organic Pollutants (POPs) significantly impact biodiversity, with various factors influencing their effects on species and ecosystems. Species in poor body condition, like carnivores and predators, are more vulnerable to POPs due to weakened immune systems and reduced detoxification abilities. Dietary habits also affect the accumulation of POPs, as chemicals biomagnify up the food chain. Carnivores accumulate higher concentrations, leading to reproductive failures, hormonal imbalances, and death, while herbivores face …
