These emissions have been linked to increased cancer rates and respiratory issues, with residents of communities near mills in Kalamazoo, Michigan, and Edmundston, New Brunswick reporting negative health effects and expressing concerns about air quality. While paper is often seen as a more environmentally friendly alternative to plastic, the industrialization of paper production and the pollution it generates reveal a darker side to the industry.

Pulp mills emit 23 million pounds of hazardous air pollutants annually

Pulp and paper mills are a major source of air pollution, with the industry emitting large amounts of atmospheric pollutants and greenhouse gases. According to Earthjustice, an environmental law firm, the roughly 100 pulp mills operating in the United States emit about 23 million pounds of hazardous air pollutants annually. These pollutants include toxic metals like mercury, organic pollutants like benzene and dioxins, and acid gases like hydrogen chloride and hydrogen fluoride. The health impacts of exposure to these pollutants can be serious, with research linking pulp mills to increased cancer rates, respiratory issues, and developmental damage in children.

The pollution from these mills has led to a lawsuit filed in 2018 by Earthjustice on behalf of community groups in Louisiana and Washington State, as well as the Sierra Club. The lawsuit argued that the Environmental Protection Agency (EPA) violated federal law by failing to regulate toxic air emissions from pulp mills for almost 20 years, despite the requirements of the Clean Air Act. The U.S. Court of Appeals for the District of Columbia Circuit ruled in favour of the communities, stating that the EPA must ensure its pollution standards for the pulp mill industry include limits on all toxic pollutants emitted.

Despite this ruling, the issue of air pollution from pulp and paper mills persists. A study of a pulp and paper mill facility in Edmundston, New Brunswick, Canada, and Madawaska, Maine, United States found that the mills had exceeded national air quality regulations multiple times between 2010 and 2017. The study also linked the air pollution emitted by these mills to various types of cancer, respiratory diseases, and cardiovascular diseases.

The pulp and paper industry's energy-intensive processes produce multiple contaminants, impacting both air and water quality. The cost of compliance with emission standards is estimated to be significant, with nationwide capital costs of $5.9 million and total annualized costs of $2.1 million per year. However, the human and environmental health impacts of failing to address these emissions are also considerable.

Overall, the issue of air pollution from pulp and paper mills is a complex and ongoing challenge, requiring increased regulation, improved mill operations, and continued research to protect the health and well-being of communities affected by this pollution.

Paper mills are linked to increased cancer rates

Paper mills emit about 23 million pounds of hazardous air pollutants annually, including benzene, mercury, and the potent carcinogen dioxin. These emissions have been linked to increased cancer rates in nearby communities. For example, in Kalamazoo, Michigan, the air pollution caused by paper mills has been a long-standing issue, with residents reporting negative health effects such as asthma.

A cohort study of 7988 workers in Swedish soft paper mills from 1960 to 2008 found that high-exposure workers with more than 10 years of employment had an increased incidence of colon, small intestine, thyroid gland, and lung cancers. Lower-exposed workers also experienced an increased incidence of connective tissue tumours (sarcomas) and pleural mesothelioma. While the exact causes of these increased cancer rates are not yet fully understood, exposure to asbestos is believed to be a contributing factor, particularly for mesothelioma.

In addition to the health risks posed to workers, pulp and paper mills also endanger the health of surrounding communities. Previous studies have linked air pollution emitted by these mills to various types of cancer, as well as respiratory and cardiovascular diseases. For example, a study in New Hampshire found an increase in cancers of the digestive tract and lymphopoietic tissues among pulp and paper mill workers. Another study using geospatial analysis identified clusters of counties with high ovarian cancer incidence rates in proximity to large numbers of pulp and paper mills.

The negative health impacts of paper mills extend beyond cancer. For instance, mercury exposure can damage the developing brains of children and fetuses, and organic pollutants emitted by pulp mills can cause birth defects and developmental harm to babies and children. The long-term health effects of exposure to toxic air pollution from paper mills are a serious concern for nearby communities.

Air pollution from paper mills can cause wheezing in adolescents

Paper mills are known to emit large quantities of air pollution. There are around 100 pulp mills operating in the United States, and they emit roughly 23 million pounds of hazardous air pollutants annually. These pollutants include toxic metals like mercury, organic pollutants like dioxins, and acid gases like hydrogen chloride and hydrogen fluoride. Research has linked exposure to these pollutants to serious health issues, including cancer, birth defects, and respiratory problems.

Several studies have found a possible association between proximity to paper mills and adverse health effects, particularly among adolescents. One study in North Carolina examined the respiratory health of 64,432 adolescents and found that the prevalence of daytime wheezing was elevated among students attending schools located within 30 miles of a paper mill, especially for smokers and those exposed to cigarette smoke. Similar results were observed in Finland, where respiratory symptoms increased following a major air release from a paper mill.

The impact of paper mill pollution on adolescents' respiratory health is a significant public health concern. The combination of tobacco smoke exposure and pollution from paper mills may worsen the situation for these children, leading to negative medical, behavioral, and educational consequences. The high prevalence of wheezing and asthma among children highlights the urgency of addressing this issue.

To protect communities living near pulp mills, regulatory actions are essential. In 2020, the U.S. Court of Appeals affirmed that the Environmental Protection Agency (EPA) has a mandatory duty under the Clean Air Act to regulate and limit all toxic air pollutants emitted by pulp mills. This decision was a response to communities' long-standing concerns about the health impacts of uncontrolled toxic pollution from these mills.

Paper mills emit nitrogen oxides, sulfur dioxide, and carbon dioxide

Paper mills are a significant source of air pollution, emitting several dangerous pollutants, including nitrogen oxides, sulfur dioxide, carbon dioxide, and other toxic substances. These emissions have severe environmental and human health impacts, underscoring the need for stricter regulations and sustainable practices in the paper industry.

Nitrogen oxides (NOx) are among the key pollutants released into the atmosphere by paper mills. High levels of NOx can contribute to the formation of ground-level ozone, a harmful pollutant that affects respiratory health and damages crops and ecosystems. Over time, nitrogen oxides can also contribute to the acidification of soil and water bodies, disrupting aquatic ecosystems and harming plant life.

Sulfur dioxide (SO2) emissions from paper mills have been a persistent issue. In the United States, pulp and paper mills emitted an estimated 412,000 tons of SO2 in 2000, with coal and residual oil burning in boilers being the primary sources. While SO2 emissions have decreased since 1980, they still pose a significant threat to air quality and human health, contributing to respiratory issues and acid rain.
