Mercury and Lead Contamination in Wildlife

Understanding Mercury Contamination

Mercury, a hazardous heavy metal, poses a significant threat to wildlife, especially in aquatic ecosystems. It tends to accumulate in large, carnivorous fish, posing risks to human health when consumed. Although the benefits of fish consumption generally outweigh the risks, vulnerable populations like pregnant women and young children should opt for fish with lower mercury levels.

To mitigate mercury exposure, choosing fish such as brook trout, brown trout, rainbow trout, and yellow perch, which have lower mercury concentrations, is advisable. Conversely, species like walleye, smallmouth bass, and chain pickerel exhibit higher mercury levels.

For the latest advisories and guidelines on mercury contamination, referring to authoritative sources such as or is essential.

Lead Poisoning in Wildlife

Lead poisoning presents a significant threat to water birds like loons, often resulting in fatal consequences. These birds ingest lead fishing sinkers and jigs lost by anglers, leading to adverse health effects. Shockingly, up to 50 percent of adult loon deaths can be attributed to lead poisoning, making it a pressing concern in the Northeast.

Addressing this issue requires collective action. Transitioning to nonlead fishing tackle is a crucial step individuals can take to mitigate lead contamination. Additionally, raising awareness among fellow anglers about the hazards of lead and advocating for the adoption of nonlead alternatives is vital.

Ways to Contribute to Wildlife Conservation

Beyond individual actions, supporting broader conservation efforts is imperative. Removing lead sinkers and jigs from tackle boxes, clearing spent fishing lines from water bodies and shorelines to prevent entanglement, and maintaining a respectful distance from wildlife are essential practices.

Furthermore, contributing to initiatives dedicated to nongame wildlife conservation is key. This can be achieved through various means, such as donating to the Vermont Nongame Wildlife Fund via state income tax forms, purchasing Vermont Conservation license plates for vehicles, or acquiring Vermont Habitat Stamps.

Preventing Human Exposure to Lead from Fishing Sinkers

Understanding the Risks

Lead, a toxic substance, poses significant health risks when ingested, inhaled, or absorbed through the skin. Fishing sinkers containing lead can contribute to lead exposure, necessitating caution and adherence to preventive measures.

Guidelines for Safe Handling

To minimize the risk of lead exposure, it's crucial to handle lead sinkers with care and follow these guidelines:

  1. Switch to Lead-Free Alternatives: Opt for sinkers made of materials such as steel, bismuth, tungsten, resin, or glass, which do not contain lead. These alternatives provide effective weights for fishing while eliminating the risk of lead exposure.

  2. Practice Proper Hygiene: After handling lead sinkers, wash your hands thoroughly with soap and water. This simple yet essential step helps remove any traces of lead, preventing potential absorption through the skin.

  3. Avoid Oral Contact: Refrain from putting lead sinkers in your mouth under any circumstances. Additionally, ensure that young children do not handle lead sinkers or put them in their mouths, as children are particularly vulnerable to the adverse effects of lead exposure.

Taking Action in Case of Suspected Lead Poisoning

If there are concerns about lead poisoning in yourself or a child, prompt action is necessary. Contact the Vermont Department of Health, Healthy Homes Lead Poisoning Prevention Program at (800) 439-8550 or (802) 863-7220 for assistance and guidance.
