CHAPTER ONE
INTRODUCTION
1.1 Background of the study
Waste generation is an inherent mechanism in all organisms. Human activities and processes follow a cyclical pattern that produces trash of different magnitudes. Within an urban context or municipality, the production, conversion, and consumption of materials and substances result in the generation of trash. Within this particular framework, the garbage produced is commonly known as Municipal Solid garbage (MSW) (Olawuyi et al., 2022). Industrial waste management is a significant problem affecting industries in Cameroon. As a result, occupational health and safety practices are not as advanced as in more industrialized civilizations. A significant number of enterprises in Cameroon frequently release their wastewater into surface bodies of water (such as oceans, seas, and streams) without undergoing any type of remediation or treatment (Agagu, 2019).
The World Health Organization (2019) has defined trash as an item that the owner no longer desires at a specific moment and location, and that has no current or perceived market worth. According to Ndume (2017), waste is defined as any residual material or undesirable byproduct that results from a process or activity (Agagu, 2019). According to the IFC (2017), an environmental and industrial context of waste refers to any solid, liquid, or contained gaseous materials that are discarded through disposal, recycling, burning, or incineration. These materials may be a by-product of a manufacturing process or an obsolete commercial product that can no longer be used for its intended purpose and needs to be disposed of (IFC, 2017).
Industrial waste encompasses liquid waste water or effluents, gaseous emissions, and solid waste. Although gaseous emissions are a significant concern, liquid waste and effluents have a more severe and immediate impact on the health of workers (Garcia et al., 2023). Industrial wastes are inherently dangerous and, as the name suggests, have the potential to harm human health and the environment if not managed correctly. Toxic waste pollutes the earth, water, and air. The contamination of these three essential elements crucial to human existence undeniably establishes a fragile and harmful connection that hinders sustainable progress and advancement. The health effects encompass exposure to hazardous substances through the mediums of air, water, and soil; exposure to infectious agents and biological pollutants; stress caused by unpleasant odors, noise, pests, and visual disturbances; the risk of fires, explosions, and ground sinking; as well as incidents involving spills, accidents, and emissions from transportation (Xian, 2018).
Employees are unquestionably subjected to a diverse range of risks of different levels of severity, based on the precise tasks of their profession. For example, a miner may put his life at risk by being subjected to high temperatures, unstable lighting conditions, and air with low oxygen levels. Similarly, an industrial worker in an asbestos plant may be exposed to harmful air pollutants such as toluene and benzene (Olawuyi et al., 2022). Approximately 2 million working hours are lost due to job-related illness, while an additional 2 million individuals report suffering from illnesses they attribute to their employment (Armstrong et al., 2021). Industrial pollution has a direct impact on health due to the release of harmful substances by the industry. Exceeding a certain threshold, these substances have detrimental impacts on human health. The effects manifest in several organs such as the heart, blood, kidneys, reproductive organs, lungs, and liver, among others (Ndiaye et al., 2020).
Effective management of industrial waste is crucial for ensuring workplace safety and preserving environmental integrity, especially in quickly industrializing urban areas such as Douala, Cameroon. As industries grow, the amount of waste they produce also increases, which includes dangerous substances that can have serious negative effects on the health of workers if not handled correctly (Nkwocha, 2018). Improper disposal and handling of industrial waste can result in several health complications, including respiratory ailments, dermatological disorders, and more serious consequences including chronic diseases and malignancies (Pat-Mbano, 2020). Workers face substantial health hazards due to industrial waste, which consists of dangerous chemicals, heavy metals, and other harmful substances. Research has demonstrated that insufficient control of industrial waste can result in the exposure to hazardous compounds, which can cause various health problems such as respiratory ailments, skin illnesses, and neurological conditions (Rasmussen et al., 2020; Zhang & Zhang, 2019). Improper waste disposal can result in the contamination of air and water sources, hence worsening health hazards for workers (Muller et al., 2018).
Douala, being the primary economic center of Cameroon, hosts a wide array of sectors, encompassing manufacturing, textiles, and chemical processing (Nguyen et al., 2021). These businesses produce significant quantities of garbage, and the efficiency of waste management procedures in this setting is a specific challenge. Studies suggest that waste management procedures in underdeveloped nations, particularly Cameroon, frequently encounter obstacles such as insufficient infrastructure, weak enforcement of regulations, and limited resources (Akinbami et al., 2022; Boateng & Kuitunen, 2017). Workers in industrial sectors in Douala are regularly exposed to dangerous waste materials. However, there is a lack of comprehensive research on the health effects of industrial waste management in this area. Prior studies have identified deficiencies in waste management procedures and their direct association with the health consequences experienced by workers (Osei et al., 2019). Poor waste management can result in increased concentrations of particulate matter and hazardous emissions, which have been linked to respiratory ailments and cardiovascular disorders (Kumar et al., 2021; Singh et al., 2017). This study aims to examine the impact of industrial waste on the health of workers in certain industries located in Douala, Cameroon.
1.2 Statement of the problem
Industrial activities produce substantial quantities of trash, which, if not well controlled, can have profound repercussions on both the environment and human well-being. The rapid growth of industrial operations in Douala, Cameroon has resulted in a significant increase in trash generation. This has raised concerns regarding the efficiency of waste management procedures and their potential impact on the health of workers. Although proper waste management plays a crucial role in protecting health, there is a significant dearth of detailed study on this matter specifically in the context of Douala.
The swift industrialization of Douala, Cameroon, has yielded substantial economic advantages, although it has concurrently presented intricate environmental hurdles, namely in the domain of industrial waste management. The escalating quantity of trash produced by enterprises, including perilous substances, presents significant health hazards to individuals who frequently labour in close proximity to these pollutants. Ineffective management practices, such as insufficient segregation of waste, poor disposal methods, and absence of protective measures, worsen these hazards, resulting in various occupational health problems (Nwachukwu, 2013). Research indicates that inadequate handling of industrial waste might result in the exposure to dangerous substances such as heavy metals, toxic compounds, and particulate matter (Muller et al., 2018; Zhang & Zhang, 2019). Employees in sectors with insufficient waste management infrastructure face a higher likelihood of experiencing health issues such as respiratory ailments, skin disorders, and neurological disorders (Rasmussen et al., 2020; Singh et al., 2017). The deposition of trash and the emission of pollutants into the environment worsen these health hazards, resulting in persistent health problems among workers (Kumar et al., 2021).
Although there are regulations in place to regulate industrial waste, the enforcement and compliance with these norms are variable. In Douala, numerous enterprises operate with inadequate waste management techniques, which expose workers to hazardous compounds. These substances can have both immediate and long-term health effects, including respiratory ailments, skin disorders, and even cancer (Nguyen et al., 2021). In addition, the absence of knowledge and instruction on the proper management and elimination of industrial waste exacerbates the susceptibility of workers (Ngwuluka, Ochekpe, & Odumosu, 2020).
The issue is exacerbated by the scarcity of study and data regarding the precise health consequences of workers in Douala being exposed to industrial waste. The lack of understanding in this area obstructs the progress of specific measures and strategies that could reduce these dangers and enhance the quality of working environments. Consequently, it is imperative to examine the impact of industrial waste management methods on the well-being of employees in specific sectors in Douala, Cameroon. The objective is to pinpoint the underlying reasons of these health problems and suggest practical remedies for enhancement. Therefore, the necessity for this investigation arises.
