Chemical Exposure and its Impact on the Population

Benchmark – Policy Brief


Environmental health centers on the study of the relationship between people and their environment. As a domain of public health, it aims to promote health and well-being, and the establishment of safe communities. Environmental health policies are, therefore, aimed to protect people and ensure the provision of healthy environments by reducing the impact of chemical exposure in air, soil, water, and food (American Public Health Association, 2021). This essay aims to explore the issue of chemical exposure and its impact on the population. The essay further describes the current policy strategies and their impact on the health care delivery system.

Policy Health Issue

Approximately 25% of all diseases worldwide are caused by environmental factors. In the US, chemical exposure causes the four leading childhood problems i.e., asthma, lead poisoning, cancer, and developmental disabilities. Chemical exposure is not limited to a certain place rather it can occur at home, workplaces, schools, and all over communities. It may be caused as a result of unintentional releases, use of certain domestic products, or contact with hazardous sites. Thousands of chemicals make people vulnerable through food intake, drinking water, and air contaminants. This wide range of exposure to the population makes chemical poisoning a national-level issue (Agency for Toxic Substances and Disease Registry, 2021).

Problem Statement

In the United States, chemical poisoning costs more than $54 billion for children-related health problems alone. The issue is further aggravated when exposure occurs within a community. The identification and control of community-related exposure are increasingly difficult. Initially, the presence of hundreds of chemical dumpsites was suspected across the Nation, however, since then thousands of waste sites have been discovered. These range from accidental spills to dumps and have resulted in miscarriages and low birth weights. Similarly, exposure to toxins such as those found in pesticides, or natural metals such as lead, results in an increased risk of neurodevelopmental disorders, obesity, and asthma (Braun, 2016). Chemical exposure is also associated with negative health impacts which include gastrointestinal, carcinogenic, dermatological, respiratory, and neurological effects among others (Mnif, et al., 2011).

In the United States, regulations against chemical exposure are outlined in the legislature and enforced by the administrative government however, the problem persists as various concerned personnel evades these regulations through legal and illegal measures (Lynch, 2016). Moreover, the current policy framework is highly fragmented through numerous federal agencies in addition to state-level regulations. This fragmentation and poor policy design result in under monitoring or an absence of monitoring for many hazardous chemicals (Chiapella, et al., 2019). The “Environmental Protection Agency (EPA)” is required to evaluate all new chemicals before their release in the market, however, lack of ample staff and funds hinders the process (Botos, Graham, & Illes, 2019).

Suggestions for Addressing the Health Issue Caused by the Current Policy

To address the health issues caused by the current policy, it is important to understand the right of humans to be free from the risks of these toxins. This right should be enshrined in the policy for clear articulation of goals. Setting ambitious yet realistic policy outcomes is imperative. The evolution of a diverse knowledge base, through inclusive and outcome-focused research, would promote an in-depth understanding of the complex nature of chemical risks and the socio-technical transformations needed (Chiapella, et al., 2019). Lastly, the most important factor for any process is effective governance. Therefore, the current health issues can be addressed through institutions that ensure transparency, inclusion, and accountability.

Steps to Initiate Policy Change

Although policy change does not occur overnight, however, continuous policy analysis and evaluation are central to identify gaps and ineffective measures. For matters that concern the health outcomes of the general population, it is important to include nurses and other public health professionals in the policy process. To move towards a regenerative economy that aims to eliminate wastes, various stakeholders including researchers, policymakers, community members, and industries must collaborate. The first step is problem identification through evaluation of current policy. This is followed by recognizing the scope and severity of the problem, along with the monetary implications. The government identifies policy operation through development and strategy, identifies policy jurisdiction, and implementation of administrative measures. Continuous monitoring is conducted for further directives.

Impact on the Health Care Delivery System

Chemical poisoning negatively impacts human health. From slow poisoning resulting from prolonged exposure to rapid poisoning through ingestion of a harmful chemical, the effects are wide-ranging. In a community setting, such exposures can cause infections at a large scale and may range from gastrointestinal problems to respiratory ailments, resulting in increased visits to emergency rooms and hospitalization. Prolonged exposure at the time of gestation can cause developmental delays in children. This would not only require additional treatments during pregnancy but also extensive pediatric care. Moreover, various forms of cancers and neurological disorders may also occur over time among people increasing the need for hospital admissions. Increased hospital admissions also incur huge amounts of money by state insurers and private insurance organizations. Overall, the health care delivery system is burdened due to the increase in demand from the health care workers. Limited staff and resources, ultimately lead to poor quality service delivery (Wang, 2020).


The impact of chemical exposure is one of the most important facets of environmental health. Involvement of all stakeholders for policy change and development is a matter of great urgency to curb its long-ranging impacts on health care systems.
