Abstract:
Globally, environmental pollution continues to be a significant public health problem, and according to the World Health Organisation, pollution-induced deaths account for 23% of deaths yearly, which could be prevented if people lived in healthier environments. Despite implementing multilateral agreements and international treaties such as the Bamako, Basel, Rotterdam, Minamata, and Stockholm conventions, the United Nations Sustainable Development Goals, and national laws, toxic pollutants remain a serious environmental and public health problem in low-income countries. In the specific context of Kwekwe City, an industrial and mining area in Zimbabwe, where environmental and pollution-induced health problems associated with industries have been widely reported, this study was conducted in close collaboration with the local community. The study aimed to assess community members' perceptions regarding health risks associated with potentially toxic elements and cyanide pollution in Kwekwe City. An explorative cross-sectional study was conducted with key stakeholders and industrial settlements' residents. Face-to-face interviews with key informants and focus group discussions with residents and workers were used to gather data. A thematic approach was utilised in data analysis. Study participants, who played a crucial role in the research process, perceived that industrial pollution principally linked to cyanide, mercury and chromium posed significant environmental and health risks. This participatory approach in risk perception assessment is critical in providing insight into the scope of the problem and formulating intervention strategies. However, given that qualitative study results lack generalisability and replicability, quantitative studies need to be undertaken to determine environmental levels of toxic chemical pollutants as a complementary and validative measure.

Toxic Reactions: Overview
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...
