Water containing lead can have serious health effects. Lead poisoning occurs when lead in water is ingested into the body. Lead can cause serious health problems, especially in children. Effects of lead poisoning include nervous system damage, brain damage, developmental disorders, kidney damage and other serious health problems. Therefore, preventing lead contamination of drinking water sources is of great importance. Using lead pipes in plumbing may cause lead contamination of water sources. For this reason, it is important not to use lead pipes in plumbing, to test the water regularly and to carry out the necessary filtering and purification processes. Additionally, protecting drinking water sources, preventing environmental pollution, and operating water treatment plants effectively can also help prevent lead poisoning. Fulfilling the duties of the authorities in this regard is of great importance in terms of protecting water resources and securing public health. It is also an important issue not to use lead as a weight used in fishing. Lead weights used in fishing can harm the environment and aquatic life forms when released into water. There is a risk that lead weights will dissolve in the aquatic environment and mix with the water, causing harm to fish, aquatic plants and other creatures. Therefore, it is recommended to use alternative environmentally friendly materials in fishing. For example, weights made of environmentally friendly materials such as zinc, steel or bismuth can be used. In this way, it may be possible to protect aquatic life and fish without harming the environment. It is important that anglers and fishermen have environmental awareness and act environmentally sensitive.
