1.1 Introduction
Industrial pollution refers to the contamination of the environment through the release of harmful substances, including dust, gases, chemicals, noise, and industrial waste generated during manufacturing and production processes. According to the World Health Organization, environmental pollution is one of the leading contributors to disease and premature death worldwide, particularly in communities located close to industrial activities (WHO, 2021). The cement manufacturing industry is one of the major contributors to industrial development in Nigeria. During cement production, activities such as quarrying, crushing, grinding, kiln operations, and transportation release particulate matter and other pollutants into the environment. These emissions may reduce air quality and expose nearby residents to health problems such as coughing, asthma, breathing difficulties, eye irritation, and cardiovascular diseases when exposure occurs over a long period (UNEP, 2019).
As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the aim and objectives of the study. Others are significance of the study, scope of work, research hypothesis and questions, limitation of the study and definition of terms.
1.2 Background of Study
Industrial pollution has become one of the most significant environmental challenges affecting public health across the world. According to World Health Organization, environmental pollution is responsible for millions of preventable illnesses and deaths each year because of continuous human exposure to contaminated air, water, and soil (WHO, 2021). Industrial activities such as cement production, mining, manufacturing, and chemical processing contribute greatly to economic development by creating employment opportunities, increasing industrial output, and supporting national growth. However, these activities also generate pollutants that may adversely affect the health of people living within host communities.
Pope et al. (2002) asserted that fine particulate matter released into the atmosphere increases the risk of heart disease, stroke, and lung disorders. These findings indicate that pollutants emitted from industrial processes are capable of affecting individuals across different age groups, particularly children, older adults, and people with pre-existing health conditions. Industrial emissions therefore remain an important environmental health issue requiring continuous monitoring and effective control measures. According to United Nations Environment Programme (2019), rapid industrialization has contributed to environmental degradation in many developing countries because pollution control measures are often inadequate or poorly enforced.
Landrigan et al. (2018) reported that pollution remains one of the largest environmental causes of disease worldwide and continues to place enormous pressure on healthcare systems. According to Adejumo (2018), industrial pollution in Nigeria has become more noticeable due to the expansion of manufacturing activities across several states. Likewise, Oyekunle et al. (2013) stated that emissions from industrial operations may introduce particulate matter and toxic substances into the surrounding environment, thereby exposing nearby residents to health risks.
Madu (2007) contended that industrialization has contributed significantly to national economic growth while creating environmental challenges that require sustainable management. Cement manufacturing involves quarrying, crushing, grinding, kiln operations, packaging, and transportation, all of which may release dust, gaseous emissions, and noise into the surrounding environment. According to Meo et al. (2013), exposure to cement dust reported that workers and residents living close to cement factories frequently experience respiratory symptoms such as persistent cough, chest discomfort, wheezing, and reduced lung function.
The National Environmental Standards and Regulations Enforcement Agency (NESREA, 2018) reported that industries are expected to implement pollution prevention measures, conduct environmental monitoring, and comply with approved emission limits. Building on this perspective, United Nations Industrial Development Organization (2019) stated that sustainable industrial production depends on balancing economic growth with environmental protection and public health. Effective enforcement of environmental regulations therefore remains essential for reducing pollution-related health problems. This study is set against the backdrop of assessing the effect of industrial pollution on community health.
1.3 Statement of Problems
Investigation revealed that industrial pollution has remained a major environmental and public health concern in many industrial communities, especially where cement manufacturing activities generate dust, gaseous emissions, and noise. Residents living close to industrial facilities are often exposed to air pollutants that may increase the occurrence of respiratory illnesses, eye irritation, skin infections, and other health-related challenges. On the other hand, there are concerns that inadequate environmental monitoring, poor waste management practices, and continuous industrial activities may expose community members to avoidable health risks, thereby affecting their quality of life (World Health Organization [WHO], 2021).
Furthermore, poor environmental quality resulting from industrial pollution may affect not only human health but also agricultural activities, water quality, and the general well-being of people living within the affected communities. It is against this backdrop that this study seeks to examine the effect of industrial pollution on community health with particular reference to Dangote Cement, Obajana.
1.4 Aim and Objectives of Study
The aim of this study is to examine the effect of industrial pollution on community health using Dangote Cement, Obajana, as the case study. In achieving this aim, the following specific objectives were laid out as follows:
- To examine the major sources of industrial pollution from Dangote Cement, Obajana.
- To determine the effect of industrial pollution on the health of residents in the host community.
- To identify the common health problems associated with industrial pollution in the study area.
- To examine the effectiveness of environmental pollution control measures adopted by Dangote Cement, Obajana.
- To identify measures for reducing the effect of industrial pollution on community health.
1.5 Research Questions
The study came up with research questions so as to be able to ascertain the above stated objectives. The specific research questions for the study are stated below as follows:
- What are the major sources of industrial pollution from Dangote Cement, Obajana?
- What effect does industrial pollution have on the health of residents in the host community?
- What are the common health problems associated with industrial pollution in the study area?

The study covers the major sources of industrial pollution, the health effects experienced by residents, pollution control measures adopted by the company, and possible strategies for reducing pollution-related health problems among host communities.
1.9 Limitations of the Study
During the course of this study, there were some problems encountered which stood as limitations to the research work. Some of the limitations include:
- Time Constraint: The time frame given to accomplish this project was very short due to school academic calendar and it was carried out under pressure which made the researcher not to implement some necessary features.
- Financial Constraint: Insufficient fund tends to impede the efficiency of the researcher in sourcing for the relevant materials, literature or information and in the process of data collection (internet, questionnaire and interview).
- Initial Cooperation Delay from Respondents: A particular limitation of this work came as a result of the respondent refusal to offer their cooperation at the initial time they were contacted. This contributed in making the success of this research study difficult.
