Review on the impact of heavy metals from industrial wastewater effluent and removal technologies.

The incidence of water pollution in developing countries is high due to the lack of regulatory policies and laws that protect water bodies from anthropogenic activities and industrial wastewater. Industrial wastewater contains significant amounts of heavy metals that are detrimental to human health, aquatic organisms, and the ecosystem. The focus of this review was to evaluate the sources and treatment methods of wastewater, with an emphasis on technologies, advantages, disadvantages, and innovation.

Experimental determination of the mechanical and hydrolytic properties of chitosan/rice husk ash composite membranes.

Chitosan-based membranes are promising alternatives to synthetic membranes in a number of specialized use cases, including water purification and electrochemical devices. In application, excessive swelling when hydrated can lead to poor mechanical integrity, necessitating modifications to the polymer so as to counter this effect. Embedding inorganic fillers within an organic polymer matrix is one method of combining excellent mechanical stability with good performance.

Effects of Bryophyllum pinnatum on Dysfunctional Autophagy in Rats Lungs Exposed to Zinc Oxide Nanoparticles.

Lung inflammation as a result of exposure to toxicants is a major pathological problem. Autophagy (AP) is a process of cell self-digestion and can be disrupted by environmental toxicants, leading to oxidative stress, inflammation and cellular damage. Bryophyllum pinnatum (Lam.

Restrictive migration policies and their impact on HIV prevention, care and treatment services.

Migration policies have a significant impact on population health, particularly for individuals living with human immunodeficiency virus (HIV). These policies not only determine who is allowed to enter a country but also influence which immigrants can access services provided by the government. Some countries continue to impose restrictions on HIV-positive individuals, justifying these measures as necessary to protect public health and mitigate healthcare and economic concerns.
