Please explain.

Effect 1: The release of cyanide to the Tisza River in Hungary led to severe water pollution. This pollution can have several negative effects on the ecosystem and human health.

To find more specific effects of the cyanide release, you can refer to scientific studies, reports, or news articles that discuss the incident. Government agencies, environmental organizations, or research institutions may have conducted studies on the impact of this particular event. Websites of these organizations, scientific journal databases, or news archives may be helpful in finding relevant information.

Effect 2: The pollution caused by the release of cyanide can harm aquatic life, including fish and other organisms that depend on the river for survival. Cyanide is highly toxic and can disrupt the delicate balance of the ecosystem, potentially leading to declines in fish populations and other negative consequences.

Moving on to the issue of water pollution in general, it is a common problem that arises as countries develop industries. Here are a couple of general effects of water pollution:

Effect 1: Water pollution can lead to the degradation of water quality, making it unsafe for human consumption. Industrial activities and the discharge of untreated wastewater into rivers or other water bodies can introduce toxic substances, chemicals, or pathogens into the water, posing health risks to people who rely on it for drinking or other purposes.

Effect 2: Water pollution can harm aquatic ecosystems by destroying habitats, reducing biodiversity, and disrupting the natural balance of ecological processes. Polluted water can contain high levels of nutrients or contaminants, leading to the growth of harmful algal blooms, oxygen depletion, and the decline of certain species.

Moving on to Poland's water pollution issue, you mentioned that most rivers in Poland are unsafe to drink due to contamination from various sources. Here are a couple of potential effects of this situation:

Effect 1: People in Poland may face health risks due to the unsafe drinking water. Consuming contaminated water can lead to waterborne diseases such as gastroenteritis, typhoid, or cholera. These illnesses can cause severe symptoms and even mortality if left untreated.

Effect 2: The contamination of rivers in Poland can harm the environment, including aquatic ecosystems and the wildlife that depends on these water bodies. Exposure to pollutants in the water can lead to negative impacts on fish, amphibians, and other organisms, affecting their reproduction, survival, and overall well-being.

Regarding the formation of smog and its effects on human health, there are several potential consequences:

Effect 1: Breathing polluted air containing smog can lead to respiratory issues such as asthma, bronchitis, or other chronic obstructive pulmonary diseases (COPD). Smog contains pollutants like particulate matter, ozone, nitrogen oxides, and volatile organic compounds, which can irritate the respiratory system and cause various respiratory problems.

Effect 2: Prolonged exposure to smog has been linked to increased risks of cardiovascular diseases, including heart attacks, strokes, and other cardiovascular events. The fine particulate matter and pollutants in smog can enter the bloodstream and cause inflammation, damage blood vessels, and contribute to the development of heart-related health issues.

Effect 3: Smog can also impact overall quality of life, leading to reduced visibility, unpleasant odors, and decreased outdoor recreational activities. It can also have economic implications in terms of healthcare costs, decreased tourism, and potential impacts on productivity.

As for the cooperation between nations to clean the air, it refers to collective efforts by different countries to address air pollution issues. Through international agreements, policies, and collaborations, countries exchange knowledge, technologies, and best practices to reduce emissions and improve air quality.

Efforts may include the implementation of stricter emission standards, the promotion of clean energy sources, the establishment of monitoring and reporting systems, and the sharing of research findings and solutions. This cooperation aims to mitigate the negative impacts of air pollution and protect public health and the environment for the benefit of all nations involved.
