Industrial waste
One notable example of industrial waste causing soil pollution in Hungary occurred in 2010 when a corner wall of a waste-retaining pond at the Ajkai Timföldgyar alumina plant in western Hungary collapsed. This incident resulted in the release of toxic red sludge that inundated nearby towns, causing chemical burns and fatalities.
In addition to direct releases of industrial waste, indirect impacts on soil pollution are also evident. Industrial activities contribute to air pollution, with emissions of ammonia and nitrogen oxide being significant factors in acid rain formation. This, in turn, affects soil quality. Furthermore, the growing battery industry in Hungary has raised concerns about the production and disposal of hazardous waste, including heavy metals and chemicals like NMP. While annual check-ups are mandated, experts recommend more frequent monitoring of soil and water quality to ensure early detection of any potential issues.
The Hungarian government has recognized the importance of addressing these issues and has implemented measures to improve waste management and reduce adverse effects on the environment. However, critics argue that more needs to be done to ensure sustainable practices and protect the health and well-being of Hungarian citizens and their surrounding ecosystems.
Overall, industrial waste is a critical factor in soil pollution in Hungary, and addressing this issue through improved waste management, stricter regulations, and increased environmental awareness is essential to mitigate its impacts on the country's soil quality and natural resources.

Car emissions
The impact of car emissions on soil pollution is multifaceted. Firstly, emissions from vehicles contribute to air pollution, which then leads to acid rain. Acid rain falls onto the soil and can destroy it, causing soil erosion and desertification. This polluted soil then runs off into water sources, contributing to water pollution. Additionally, the deposition of pollutants from car emissions can directly contaminate the soil, particularly near highways and roads. Studies have shown that plants grown near highways have higher lead concentrations, indicating that car emissions can result in the contamination of soil with heavy metals.
Hungary's rapid industrialization and increase in industrial production have also led to a rise in vehicle usage and exports, contributing to air and soil pollution. The country's economic activities, including the manufacturing and exporting of vehicles, industrial machinery, and electronic goods, have resulted in elevated levels of pollution. The burning of fossil fuels and industrial production are significant sources of carbon dioxide (CO2) emissions, which contribute to climate change and air quality issues.
To address the issue of car emissions and its impact on soil pollution in Hungary, several measures can be considered. Firstly, improving fuel efficiency standards and promoting the use of alternative energy sources, such as electric vehicles, can help reduce the combustion of fossil fuels and the resulting emissions. Secondly, implementing stricter emission control regulations and enforcing regular vehicle maintenance can minimize the release of pollutants from cars. Additionally, investing in public transportation infrastructure and encouraging carpooling or shared mobility services can help reduce the overall number of vehicles on the road, thereby decreasing emissions and their impact on soil pollution.
While car emissions are a significant contributor to soil pollution in Hungary, it is important to recognize that other factors also play a role. Poor agricultural practices, such as the use of specific pesticides, and industrial waste disposal contribute to soil pollution. Therefore, a comprehensive approach addressing multiple sources of pollution is necessary to effectively mitigate the issue of soil pollution in Hungary.

Lead and other heavy metals
Lead is a toxic heavy metal that has become much more prevalent in the environment since industrialization and poses significant health risks. A study on urban soils in the former heavy industrial cities of Salgótarján and Ózd in northeastern Hungary revealed a heterogeneous lead distribution, with levels ranging from 8.5 to 1692 mg kg-1 in Salgótarján and 6.6 to 1674 mg kg-1 in Ózd. The primary sources of lead contamination in these areas were identified as coal ash in Salgótarján and smelter slag in Ózd, both of which pose health risks to residents.
Industrial byproducts, such as coal ash and smelter slag, are not the only sources of lead contamination in Hungary. Vehicle emissions, iron and steel works, coal mines, and coal-fired power plants also contribute to the presence of lead in the soil. These anthropogenic activities have led to a positive correlation between the presence of lead and certain soil characteristics, such as TOC, TN, Mn, and Pb in Salgótarján, and Fe, Mn, and Pb in Ózd.
In addition to lead, other heavy metals contribute to soil pollution in Hungary. Arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), zinc (Zn), antimony (Sb), cobalt (Co), and nickel (Ni) are among the heavy metals detected in European topsoils. Historical and recent industrial and mining activities have resulted in elevated levels of these metals, with soil contamination being a significant concern across Europe and globally.
The presence of heavy metals in the soil can have detrimental effects on both agriculture and human health. Food safety and sustainability are at risk due to the contamination of agricultural lands. Furthermore, the health problems caused by lead and other heavy metals can have significant impacts on the well-being of Hungarian residents, particularly in former industrial cities.
To address the issue of lead and heavy metal soil pollution in Hungary, it is crucial to implement effective waste management systems and improve industrial and agricultural practices. By reducing the release of toxic chemicals and properly managing byproducts, it is possible to mitigate the spread of heavy metal pollution and minimize the associated health and environmental risks.

Pesticides and herbicides
Poor agricultural practices, including the use of pesticides and herbicides, are major contributors to soil pollution in Hungary.
Pesticides are used in intensive farming to fight plant pests and diseases (insecticides and fungicides), kill weeds (herbicides), and accelerate seed growth (defoliants). The widespread use of pesticides for agricultural and non-agricultural purposes has resulted in their residues polluting surface and groundwater resources in Hungary.
Since 1999, ongoing systematic monitoring of pesticide residues in environmental matrices in Hungary has revealed extensive point contamination. Over 2000 surface, ground, and raw drinking water samples have been analyzed in different monitoring projects in Hungary and neighbouring countries between 1990 and 2015. The effects of pesticide contamination on ecological farming and drinking water supply have been assessed, with herbicides related to maize production identified as the main water pollutant ingredients of agricultural origin in Hungary.
The use of pesticides in agriculture has led to soil pollution, with certain pesticides, such as diazinon, atrazine, and trifluralin, being commonly detected in water samples. These pesticides have been found in significant concentrations, with atrazine detected in concentrations ranging from 40 to 250 ng/L. The persistence of these pesticides in the environment is due to their slow dissipation, with some pesticides, like trifluralin, having long dissipation times due to limited water solubility.
In addition to water pollution, the use of pesticides has also contributed to soil pollution in Hungary. Soil disinfectants and herbicides have been detected in water samples, indicating their presence in the soil. The detection of these chemicals in water samples is concerning, as it suggests that they have leached from the soil into water sources. This highlights the impact of agricultural practices on soil and water quality.
To address the issue of pesticide-related soil pollution, Hungary has implemented measures such as the EU pesticide re-registration process, which has led to a decrease in the presence of certain pesticides like diazinon, atrazine, and trifluralin as contaminants. However, other pesticides, such as acetochlor, have emerged as significant pollutants, with their use resulting in temporarily enhanced levels in raw drinking water. The persistence of pesticide residues in the environment and their impact on water and soil quality underscores the need for continued monitoring and the development of sustainable agricultural practices that minimize the use of these chemicals.
