Minimizing risks of soil contaminants in urban gardens nc state extension publications electricity bill cost per month


Gardening in urban areas is increasingly popular in North Carolina. Growing food locally (which requires less energy for packaging, transit electricity generation in usa, and storage), connecting to nature at your doorstep, engaging children in agriculture, and controlling the amount and types of pesticides and fertilizers applied to your food are among the many wonderful reasons to garden in the city. But urban gardening poses potential risks. Before planting, city gardeners must evaluate how a prospective site was previously used, to identify potential safety hazards—including chemical contaminants—in the soil.

This publication alerts prospective gardeners to some of the most common contaminants in urban soils, such as lead and other toxic metals, solvents, pesticides, and total petroleum hydrocarbons. Readers gas engine tom will learn how to minimize potential risks to gardeners and to those who consume garden produce. The document includes information regarding site characterization, common contaminants, soil testing, interpretation of results, and strategies for reducing exposure risks.

Take a careful look at the history of land use before selecting a site to garden. Evaluate not only the actual plot to be developed but electricity transmission vs distribution the surrounding lots as well. Start with city records available online or at city hall. They will help you identify the property class, zoning information, and current and previous owners. Long-time neighbors can be valuable sources of information.

1 Different metals are likely to result from specific activities or sources, i.e. paint, galvanized metal, pesticides, wood preservatives, etc. Inorganic pollutants like nitrates and trace elements are naturally found in the environment, but in urban areas they may be concentrated to unsafe levels. Examples include arsenic, barium, cadmium, chromium, lead, mercury, and zinc.

If your analysis reports levels lower than those in Tables 3a and 3b, gardening at that site presents minimal risks. If your soil’s levels exceed those in the chart, you should either choose a different site or take precautions to protect gardeners, neighbors, and gas 89 those who consume produce from the garden. If you decide to garden on the site, use some of the strategies in Table 4 to minimize physical contact with contaminated soil and plant uptake of contaminants. These strategies will help prevent toxins from being absorbed through the skin, breathed in as dust, or consumed.

Lead is the most common contaminant in urban soils, and gas monkey monster truck body intake of contaminated soil—through direct ingestion, dust inhalation, or exposure to soil clinging to produce—may pose a serious health risk. Young children and pregnant women are at the greatest risk from lead contamination, as high lead exposure may result in behavioral and learning disabilities. Lead may be derived from a number of pervasive sources, including gasoline emissions, paint chips from older electricity review worksheet buildings, plumbing pipes, and industrial processes. Lead accumulates where it is deposited and is not easily removed from soil.
