Aquatic environments

The tropical water environment faces increasing exposure to temperature extremes and contaminants stemming from human activities. Elevated temperatures and pollution levels in rivers and ponds have the potential to induce cumulative impacts on the diversity of aquatic ecosystems. However, the combined effects of these environmental changes on the life cycle of the Eucyclops euacanthus copepod, a bioindicator of aquatic ecosystem remain understudied.

Water quality plays an immensely significant role in safeguarding the health of humans and other species on the planet. Polluted water sources can contain harmful substances such as heavy metals, pesticides, bacteria, and viruses, which can pose threats to human health and other organisms. Water quality is also a crucial factor in protecting the environment and sustaining the ecosystems of freshwater and marine environments. Polluted water sources can impact the lives of aquatic animals and plants, causing harm and endangering biodiversity by disrupting the food chain.

In recent years, the understanding of processes on material surfaces has drawn considerable interest from scientists. The adsorption stage is important for further insights into surface interactions and photocatalytic reactions. In this study, we use density functional theory computations to investigate the adsorption of sulfamethoxazole (SMX) molecules on the rutile-TiO2 (001) surface (r-TiO2 ).

Aquaculture, also known as aquafarming, is the farming of aquatic organisms such as fish, crustaceans, molluscs and aquatic plants.[1][2] Aquaculture involves cultivating freshwater and saltwater populations under controlled conditions, and can be contrasted with commercial fishing, which is the harvesting of wild fish.[3] Mariculture refers to aquaculture practiced in marine environments and in underwater habitats.

Compare to other documents, our study was for the first time validated the quality criteria of ICP-MS for analyzing nineteen metal levels in wastewater samples. The application of this method was then tested by analyzing nineteen metal levels in twenty-three wastewater samples in the Tham Luong Canal in Ho Chi Minh City. Based on these results, the correlation of the concentration of these metals in wastewater samples was determined.

Goldfish (Carassius auratus) may survive in aquatic environments with low oxygen partial pressures. We investigated the contribution of respiratory proteins to hypoxia tolerance inC. auratus. We determined the complete coding sequence of hemoglobinaandband myoglobin, as well as partial cDNAs from neuroglobin and cytoglobin.

A variety of organisms have been investigated to evaluate their potential as biological indicators of different forms of pollution in the aquatic environment (e.g. review by Gunkel 1994). Certain species have been identified as being highly sensitive either in their physiological response to aquatic contaminants or in their ability to accumulate particular toxins in a dose-time dependent manner.
