It is responsible for the great stability of perfluoroalkyl and polyfluoroalkyl substances, commonly referred to as “PFAS”, a group of man-made chemicals that include perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA). Thermal stability, surface activity, dielectric characteristics, chemical resistance, and inertness are just a few of the technical advantages that this group has over hydrocarbons, and since the 1950s, these chemicals have been largely utilized in a variety of domestic and industrial endeavors. The hydrophilic and lipophilic nature of this class of chemicals accounts for its uniqueness. Up until today, the chemistry and ecotoxicology of these chemicals continue to emerge. Issues concerning the destructive power of ignorance expedited by an ineffective regulatory institution continue to show that manufacturing chemicals are insufficient without giving serious thought to issues of openness and humanity’s awareness of its own safety. When discussing the nature of humanity and how it can be defined or redefined, it is important to allude to the significance of integrating business with ethics in its various forms. This paper highlights the importance of holding polluters accountable for PFAS contamination cleanup costs while emphasizing the need for chemical manufacturers to test and disclose the health and environmental effects of PFAS compounds. In addition, the sources, types, properties, applications, distribution, toxicological implications, regulations, and analytical methods associated with PFAS (per- and polyfluoroalkyl substances) are explored. The effectiveness of the remedial methods described in this paper needs to be progressively tested while exploring other sustainable approaches.展开更多

The current liberal prevention strategy with programs aimed at risk reduction interventions in particular for sexual behavior and injecting drug use has been expanded by antiretroviral treatment approaches. It was expected to keep the prevalence of infectious individuals below a certain threshold to curb self-sustaining chains of HIV infections. The introduction of biomedical approaches by ART/HAART with regard to practicing risk reduction behavior has been received as an exemption of responsibility by certain populations who are defined as “at-risk” population. Certain parts of the hard-to-reach, high-risk population have returned to unsafe sex practices leading to careless behavior which in turn has promoted the spread of HIV. This is supported by modern trends in risk societies where with regard to HIV basic principles of ethics and tenets of the Human Rights like “don’t harm other people” have lost any normative power. In addition, with the support of NGOs, legal norms such as protecting the “bodily integrity of individuals” have been ignored, allowing the “passing of HIV to partners” to become socially acceptable behavior. As a whole, in defiance of the endeavors of prevention applied so far, certain societies are exposed to an ongoing spread of HIV.展开更多
