Air pollution from coal burning
While the Middle Ages are often imagined as a smelly and polluted period, medieval people were not indifferent to the issue of pollution. In fact, they recognised the link between pollution and health and well-being, and took steps to address it.
One source of air pollution in medieval towns was coal burning. The burning of coal, or "sea-coal", first emerged as a source of air pollution in the 13th century. It was originally shipped from Newcastle to London as ballast and was used in small quantities by smiths, lime burners, and other industries in London and English coastal towns. The smoke from sea-coal fires was considered a nuisance, and there were concerns that it could cause health problems. In 1288, a commission of inquiry was appointed following complaints from those living near lime kilns about the smoke affecting the air and causing a "peril" to those in the vicinity.
In 1307, Edward I issued a royal proclamation prohibiting the use of sea coal in kilns due to its negative impact on health and the strong smell it produced. This change in attitude towards coal burning was also influenced by the belief during the medieval period that strong odors were linked to disease. The theory of Miasma, which suggested that disease was caused by corruption of the air, further reinforced the idea that coal smoke could have detrimental health effects.
However, during the years of the Black Death (1347-1351), there was a contrasting belief that the smoke from coal had a cleansing action due to its sulphurous composition and could drive away the plague. This highlights the complex understanding and reactions medieval people had towards pollution.
While coal burning contributed to air pollution in medieval towns, it is important to note that other sources of pollution, such as waste from butcher shops, tanneries, and textile production, also played a significant role in the overall pollution levels of these towns.

Water pollution from waste dumping
Water pollution was a significant issue in medieval towns, with human and animal waste being dumped into rivers and water sources. This practice led to the contamination of drinking water and posed a grave threat to the health of the population.
One of the main sources of water pollution in medieval towns was the accumulation of human waste in rivers and ditches. Medieval cities lacked underground sewage systems, and human excrement often ended up in the cities' water sources. For example, by 1415, the Walbrook River in London had become obstructed by waste, and the public latrines located near the river contributed to a "horrible, infected, and corrupt atmosphere."
Animal waste was also a major contributor to water pollution. Livestock, such as pigs, horses, cows, and poultry, produced large amounts of dung, which was sometimes dumped into rivers and streams. In Coventry, it was prohibited to throw dung from stables into the Sherbourne River, and those who did so risked being fined. However, this did not stop the practice entirely, and the contamination of rivers was a widespread problem in medieval cities.
In addition to human and animal waste, the waste products of various trades also polluted water sources. Tanneries, slaughterhouses, and textile production generated significant amounts of waste, including blood, intestines, and chemical runoff. Butcher shops, in particular, were a source of sanitation concerns, as blood and entrails from slaughtered animals were often thrown into waterways.
The medieval understanding of the link between pollution and health was limited, and they primarily associated strong odors with disease. However, they did recognize the importance of hygiene and took some steps to improve sanitation. City councils enacted laws and fines to prevent water pollution, and tax money was used to fund streetsweepers and privy cleaners. Despite these efforts, the rapid population growth and dense living conditions in medieval towns made it challenging to maintain adequate sanitation.

Lead poisoning from drinking water
While pollution from waste and poor sanitation was a significant issue in medieval towns, lead poisoning from drinking water was also a concern. Here are some paragraphs discussing this issue in detail:
Medieval towns often sourced their drinking water from runoff collected from lead roofs, which was then stored in lead containers. Additionally, lead acetate, also known as "sugar of lead," was used to sweeten wine, further increasing lead consumption. Today, we are aware that lead poisoning can have severe health consequences, including developmental issues in children, infertility in adults, mood swings, and violent behaviour. However, the health impacts of lead poisoning were only systematically proven in the second half of the 20th century, so medieval people were likely unaware of these dangers.
Sources of Lead in Drinking Water
The use of lead in roofing and storage containers was a primary source of lead contamination in drinking water. Lead was also added to wine as a sweetener, which increased exposure. These practices inadvertently led to the consumption of lead, particularly among wealthier individuals, as lead was expensive at the time.
Health Impacts of Lead Poisoning
Lead poisoning can have serious and far-reaching health effects. In children, lead poisoning can cause developmental problems, impacting their growth and cognitive abilities. In adults, infertility is a significant concern, along with potential mood swings and violent behaviour. These health issues were likely observed in medieval times, but the specific link to lead poisoning was not established until much later.
Social and Economic Implications
The consumption of lead-contaminated water disproportionately affected the wealthy, as they could afford lead-glazed pottery and cosmetics containing white lead. Analysis of medieval skeletons reveals that rural populations had minimal lead exposure, while urban populations showed significantly higher levels of lead contamination. This suggests that lead poisoning was more prevalent in towns, where lead was more accessible and commonly used.
Medieval Understanding of Pollution
While medieval people did not have the same understanding of pollution and its health impacts as we do today, they recognised the importance of hygiene and sanitation. They implemented measures to address waste disposal and tried to mitigate offensive odours. However, the complex interplay of various pollution sources, including lead in drinking water, contributed to health issues and an increased mortality rate during that era.

Mercury poisoning from refining
Pollution was a significant concern in medieval towns, with waste accumulation, air pollution, and water contamination posing threats to public health. While mercury poisoning from refining was not a widespread issue, there are a few notable instances where it may have occurred. Here is some information on mercury poisoning from refining in the medieval period:
Mercury's Usage in the Medieval Period
Mercury, known as quicksilver, has been utilised since ancient times, including in the medieval period for various purposes. Medieval alchemists regarded mercury as the "First Matter" from which all other metals were formed. It was sought after by alchemists aiming to transmute base metals into gold. Medieval Europeans also used mercury for medicinal purposes and as a component of bright red ink in monasteries. In addition, the ancient Greeks, Romans, and Egyptians employed cinnabar, a form of mercury sulfide, in ointments and cosmetics.
Mercury Poisoning Symptoms
Mercury poisoning can manifest in numerous ways, depending on the type and extent of exposure. Common symptoms include peripheral neuropathy, resulting in itching, burning sensations, pain, and paresthesia. Other symptoms may include muscle weakness, poor coordination, numbness in the extremities, skin rashes, anxiety, memory issues, speech and hearing difficulties, and vision problems. In children, mercury poisoning can lead to acrodynia or pink disease, characterised by pink and peeling skin. Long-term complications may include kidney dysfunction and decreased cognitive abilities.
Instances of Mercury Poisoning in the Medieval Period
One notable example of mercury poisoning in the medieval period is the "Huancavelica sickness" or the "evil of Huancavelica." This term described the toxic effects of mercury vapors on miners and workers in the Huancavelica mines in Peru, which were expropriated by the Spanish in the 16th century to meet the growing demand for mercury. The refining ovens were positioned along the river, allowing the escaping vapors to settle on the surrounding environment and blow across the town, contaminating the food chain. The vapors were converted into methyl mercury by bacteria, making their way into the food chain and causing sporadic outbreaks of mercury poisoning. The threat was particularly severe for those working directly with the refining ovens, as they were forced to open the ovens before they had cooled down, increasing their exposure to toxic mercury vapors.
Another instance of mercury poisoning in the medieval period is described by Elizabeth Storie, a Scottish woman who, in her autobiography, recounts how she suffered severe mercury poisoning as a child in the 19th century. A doctor had treated her mild illness with prolonged administration of calomel, a mercury-containing medicine. This resulted in her becoming disabled due to the toxic effects of mercury.
Preventative Measures and Treatments
To prevent mercury poisoning, it is crucial to avoid exposure to mercury and consume a diet low in mercury. Proper disposal of mercury and the removal of mercury from medical devices are also essential. In cases of acute inorganic mercury salt poisoning, chelation therapy with dimercaptosuccinic acid (DMSA) or dimercaptopropane sulfonate (DMPS) can improve outcomes if administered promptly after exposure. However, the benefits of chelation for long-term exposure are unclear.

Tanneries and textile production
The tanning of animal hides into leather was a significant source of pollution in medieval towns. The process involved replacing the moisture in the hides with tannins, made from a solution of oak bark. This required removing excess fat and sinew, creating caustic lime baths, and soaking the skins in urine. These processes produced a foul stench and released harmful ammonia gas. Tanners were often banished outside the walls of towns due to the unpleasant nature of their work. However, their pollution extended beyond the town walls as they frequently dumped spent chemicals and animal by-products into streams and watercourses used by people.
Textile production was another trade that contributed to the pollution in medieval towns. While specific details of the pollution caused by textile production are scarce, it is mentioned alongside tanneries and slaughterhouses as a "messy business". The waste products of these industries were pervasive and required proper disposal.
The waste from tanneries and textile production was not limited to solid refuse but also included liquid effluents. Tanneries, in particular, generated large amounts of wastewater contaminated with chemicals and organic matter. In medieval towns, proper wastewater treatment systems were likely nonexistent, leading to the discharge of untreated or poorly treated wastewater into nearby water bodies. This would have contaminated drinking water sources and further contributed to the spread of diseases.
To address the pollution caused by tanneries and textile production, medieval towns implemented various measures. Laws were enacted to fine individuals who polluted rivers or ditches. Additionally, there were efforts to relocate craftsmen who produced dirty waste, such as tanners, to areas outside the town where they would be less offensive. These actions indicate that city leaders recognized the importance of sanitation and were attempting to improve the health and cleanliness of their towns.
While the perception of medieval cities as extremely filthy and stinky may be exaggerated, it is clear that tanneries and textile production contributed significantly to the pollution and waste management challenges faced by these towns. The accumulation of waste and the contamination of water sources were ongoing issues that required constant attention and innovative solutions.
