Clean water is essential for agriculture and industry, while natural landscapes attract tourism and recreation. By promoting sustainability and environmental stewardship, the IEPA contributes to the long-term prosperity of Illinois.

PFAS: What Are They?

Now, let's talk about PFAS. Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals that have been used in various industries since the 1940s. You might not have heard of them, but they're everywhere – from non-stick cookware to firefighting foam. The problem? They're incredibly persistent in the environment and can accumulate in our bodies over time. Because of their widespread use and environmental persistence, PFAS are now considered emerging contaminants of concern.

Common Uses of PFAS

• Non-Stick Cookware: PFAS are used to make surfaces non-stick, like in Teflon pans. This makes cooking and cleaning easier but introduces these chemicals into our food and environment.
• Food Packaging: Many food containers, such as fast-food wrappers and microwave popcorn bags, are treated with PFAS to repel oil and water. This prevents the packaging from getting soggy but can lead to PFAS leaching into our food.
• Firefighting Foam: Aqueous film-forming foam (AFFF), used to extinguish fires, especially at airports and military bases, contains high levels of PFAS. This has resulted in significant soil and water contamination in areas where AFFF was used extensively.
• Textiles and Fabrics: PFAS are used to make fabrics water-resistant and stain-resistant. This includes clothing, upholstery, and carpets. While it adds convenience, it also contributes to the widespread presence of PFAS in our homes and environment.
• Industrial Applications: Various industries use PFAS in manufacturing processes due to their unique properties, such as chemical resistance and thermal stability. This includes the production of semiconductors, lubricants, and coatings.

The Problem with PFAS

The major issue with PFAS is their persistence. They don't break down easily in the environment, earning them the nickname "forever chemicals." This means they can contaminate soil, water, and air, and they can also accumulate in the bodies of humans and animals. Exposure to PFAS has been linked to a range of health problems, including:

• Immune System Effects: PFAS can weaken the immune system, making individuals more susceptible to infections and reducing the effectiveness of vaccines.
• Thyroid Disruption: These chemicals can interfere with thyroid hormone production, leading to thyroid disorders that affect metabolism, energy levels, and overall health.
• Liver Damage: Exposure to PFAS has been associated with liver damage and elevated liver enzymes, indicating potential liver dysfunction.
• Certain Cancers: Studies have suggested a link between PFAS exposure and an increased risk of certain cancers, including kidney and testicular cancer.
• Developmental Effects: PFAS can affect the growth, learning, and behavior of infants and children. Pregnant women are particularly vulnerable, as PFAS can cross the placenta and affect the developing fetus.

Emerging Contaminants: What Else Should We Worry About?

Okay, so PFAS are a big deal, but they're not the only emerging contaminants we need to keep an eye on. Emerging contaminants are chemicals or substances that are newly identified as potential threats to human health or the environment. They might not be currently regulated, but research is ongoing to understand their impacts. These contaminants often come from various sources, including pharmaceuticals, personal care products, and industrial processes. Understanding these contaminants is crucial for protecting our water, soil, and overall health.

Types of Emerging Contaminants

• Pharmaceuticals and Personal Care Products (PPCPs): These include prescription and over-the-counter drugs, as well as products like shampoos, lotions, and cosmetics. When these substances are flushed down the toilet or washed down the drain, they can end up in wastewater treatment plants, which are not always equipped to remove them completely. As a result, PPCPs can contaminate surface water and groundwater, potentially affecting aquatic life and human health.
• Microplastics: These tiny plastic particles, less than 5 millimeters in size, come from a variety of sources, including the breakdown of larger plastic items, microbeads in personal care products, and synthetic textiles. Microplastics are found in oceans, rivers, and even drinking water. They can absorb pollutants and potentially harm aquatic organisms that ingest them. The long-term effects of microplastic exposure on human health are still being studied.
• Pesticides and Herbicides: While pesticides and herbicides are designed to control pests and weeds in agriculture and landscaping, they can also have unintended consequences. These chemicals can contaminate soil and water, affecting non-target organisms and potentially posing risks to human health. Some pesticides and herbicides are persistent in the environment and can accumulate in the food chain.
• Flame Retardants: These chemicals are added to furniture, electronics, and other products to reduce their flammability. However, many flame retardants are persistent and can accumulate in the environment and in human tissues. Some flame retardants have been linked to endocrine disruption, developmental problems, and cancer.
• Nanomaterials: These are materials with dimensions on the nanoscale (1 to 100 nanometers). Nanomaterials are used in a wide range of products, including cosmetics, electronics, and medicine. While they offer many benefits, there are concerns about their potential toxicity and environmental impact. Nanomaterials can behave differently than larger particles of the same substance, making it challenging to predict their effects on human health and ecosystems.

Why Emerging Contaminants Are a Concern

The main concern with emerging contaminants is that their potential impacts are not yet fully understood. They might be present in our environment at low concentrations, but even small amounts can have long-term effects on human health and ecosystems. Traditional water treatment methods are not always effective at removing these contaminants, and current regulations may not adequately address them. Therefore, it’s crucial to continue researching these substances and developing strategies to minimize their presence in our environment. The more we understand about these contaminants, the better we can protect our health and environment.
