Summary
Bisphenols like BPA are common environmental contaminants in water. This review covers their sources, toxicity, and effective removal technologies, often requiring combined treatment methods.
Area of Science:
- Environmental Science
- Environmental Chemistry
- Toxicology
Background:
- Bisphenols, including bisphenol A (BPA), bisphenol S (BPS), bisphenol F (BPF), and bisphenol AF (BPAF), are widely used industrial chemicals.
- These compounds are ubiquitous environmental contaminants, frequently detected in aquatic ecosystems worldwide.
- Their presence in water raises concerns due to potential toxicity to humans and other organisms.
Purpose of the Study:
- To review the sources and environmental pathways of bisphenols, focusing on aquatic environments.
- To summarize the known toxicity of bisphenols to humans and aquatic organisms.
- To evaluate various technologies for removing bisphenols from water.
Main Methods:
- Literature review of bisphenol sources, environmental fate, toxicity, and removal technologies.
- Analysis of treatment methods including adsorption, biodegradation, advanced oxidation processes (AOPs), coagulation, and membrane separation.
- Discussion of the advantages, limitations, and potential by-products of each treatment method.
Main Results:
- Adsorption, particularly using carbon-based materials, is a common removal technique.
- Biodegradation involves various microorganisms, while AOPs include UV/O3-based, catalytic, electrochemical, and physical methods.
- Both biodegradation and AOPs can generate toxic by-products requiring further treatment; membrane process effectiveness depends on membrane properties.
Conclusions:
- No single treatment method is universally effective for bisphenol removal.
- Combined treatment processes are suggested to enhance removal efficiencies and address limitations.
- Further research is needed to optimize existing technologies and manage by-products effectively.

01:22Waterproofing and Anti-Bacterial Admixtures in Concrete
105
Concrete's susceptibility to water absorption is due to the capillary action within the pores of its hydrated cement paste. This action draws water in, creating the need for waterproofing admixtures to prevent such penetration. The efficacy of these admixtures is contingent upon the water pressure, with variations arising from different conditions such as rain, capillary rise, or hydrostatic pressure in structures intended to hold water.

19.4K
Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

98
Biofilms are complex communities of microorganisms encased in a self-produced extracellular polysaccharide matrix attached to surfaces. These microbial consortia can include single or multiple species, providing enhanced survival benefits by forming organized, multilayered structures.The formation of biofilms occurs through four key stages: attachment, colonization, development, and dispersal.During attachment, free-swimming planktonic cells adhere to a surface, often facilitated by...

04:01Factors Affecting Solubility
33.7K
Compared with pure water, the solubility of an ionic compound is less in aqueous solutions containing a common ion (one also produced by dissolution of the ionic compound). This is an example of a phenomenon known as the common ion effect, which is a consequence of the law of mass action that may be explained using Le Chȃtelier’s principle. Consider the dissolution of silver iodide:

01:36Types of Toxins
1.8K
Humans continually engage with an environment rich in potentially harmful chemicals. These are introduced to our bodies through inhalation, ingestion, or skin contact. These chemicals exist in various forms, such as air and environmental pollutants, agricultural chemicals, organic solvents, and heavy metals.
Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.

01:19Quality of Water
144
In concrete preparation, the quality of water is paramount as it affects the strength and durability of the concrete. Potable water is usually preferred; however, it must not have excessive sodium or potassium to prevent compromising the concrete's integrity. Water quality is typically evaluated based on impurities such as dissolved solids, chlorides, and sulfates, and its pH value is ideally between 6 and 8. Even slightly acidic natural water may be acceptable unless it contains harmful...
