Study Notes
Pollutants in Dust Particles from Construction Activities
- Dust particles can contain silica, which poses serious respiratory risks like silicosis.
- Heavy metals, such as lead and arsenic, may be present in dust from disturbed sites, affecting soil and water quality.
- Organic pollutants, including volatile organic compounds (VOCs), can off-gas from materials used in construction, contributing to air pollution.
Emissions from Construction Vehicles and Machinery
- Emissions from construction vehicles include nitrogen oxides (NOx) and particulate matter, leading to air quality degradation.
- Diesel engines used in heavy machinery release various harmful pollutants, including sulfur dioxide (SO2) and carbon monoxide (CO).
- Construction equipment can also emit greenhouse gases, contributing to climate change.
Health Risks from Poor Air Quality
- Exposure to construction-related air pollutants can lead to chronic respiratory diseases, including asthma and bronchitis.
- Long-term exposure is associated with cardiovascular diseases and reduced lung function.
- Vulnerable populations, such as children and the elderly, are at higher risk of health complications from poor air quality.
Effects of Heavy Machinery on Soil Compaction
- Heavy machinery compresses the soil, increasing its density and reducing porosity, which can inhibit plant root growth.
- Soil compaction can lead to decreased water infiltration, increasing runoff and erosion.
- Compacted soil restricts air movement and microbial activity, negatively affecting soil health.
Consequences of Disturbing Topsoil and Removing Vegetation
- Disturbing topsoil can lead to erosion, loss of nutrients, and decreased soil fertility.
- Removing vegetation increases vulnerability to erosion and disrupts local ecosystems.
- Disturbances can release stored carbon into the atmosphere, contributing to climate change.
Impact of Construction Materials and Chemicals on Soil
- Chemicals used on-site, such as solvents and adhesives, can leach into the soil, contaminating groundwater.
- Certain construction materials, like treated wood or metals, may introduce toxins into the soil profile.
- The application of heavy fertilizers and pesticides on construction sites can lead to soil degradation and biodiversity loss.
