Urban Gardeners May Be Unaware of How Best to Manage Contaminants in Soil

02.04.2014

Consuming foods grown in urban gardens may offer a variety of health benefits, but a lack of knowledge about the soil used for planting could pose a health threat for both consumers and gardeners. In a new study from the Johns Hopkins Center for a Livable Future (CLF), researchers identified a range of factors and challenges related to the perceived risk of soil contamination among urban community gardeners and found a need for clear and concise information on how best to prevent and manage soil contamination. The results are featured online in PLOS ONE.

“While the benefits are far-reaching, gardening in urban settings can also create opportunities for exposure to contaminants such as heavy metals, petroleum products, and asbestos, which may be present in urban soils,” said Keeve Nachman, PhD, senior author of the study and director of the Food Production and Public Health Program with CLF.

“Our study suggests gardeners generally recognize the importance of knowing a garden site’s prior uses, but they may lack the information and expertise to determine accurately the prior use of their garden site and potential contaminants in the soil. They may also have misperceptions or gaps in knowledge about how best to minimize their risk of exposure to contaminants that may be in urban soil.

According to CLF researchers, urban soils are often close to pollution sources, such as industrial areas and heavily trafficked roads. As a result, many soil contaminants have been found at higher concentrations in urban centers.

To characterize urban community gardeners’ knowledge and perceptions of soil contamination risks and reducing exposure, researchers conducted surveys among urban community gardeners and semi-structured interviews with key informants in the gardening community in Baltimore, Maryland. Informants included individuals whose job function or organizational affiliation makes them knowledgeable about Baltimore City community gardening and soil contamination.

“People may come into contact with these contaminants if they work or play in contaminated soil, or eat food that was grown in it. In some cases, exposure to soil contaminants can increase disease risks, especially for young children,” said Brent Kim, MHS, lead author of the paper and a program officer with CLF. “Given the health, social, environmental and economic benefits associated with participating in and supporting urban green spaces, it is critical to protect the viability of urban community gardens while also ensuring a safe gardening environment.”

Im Focus: Worldwide Success of Tyrolean Wastewater Treatment Technology

A biological and energy-efficient process, developed and patented by the University of Innsbruck, converts nitrogen compounds in wastewater treatment facilities into harmless atmospheric nitrogen gas. This innovative technology is now being refined and marketed jointly with the United States’ DC Water and Sewer Authority (DC Water). The largest DEMON®-system in a wastewater treatment plant is currently being built in Washington, DC.

The DEMON®-system was developed and patented by the University of Innsbruck 11 years ago. Today this successful technology has been implemented in about 70...

Im Focus: Computational high-throughput screening finds hard magnets containing less rare earth elements

Permanent magnets are very important for technologies of the future like electromobility and renewable energy, and rare earth elements (REE) are necessary for their manufacture. The Fraunhofer Institute for Mechanics of Materials IWM in Freiburg, Germany, has now succeeded in identifying promising approaches and materials for new permanent magnets through use of an in-house simulation process based on high-throughput screening (HTS). The team was able to improve magnetic properties this way and at the same time replaced REE with elements that are less expensive and readily available. The results were published in the online technical journal “Scientific Reports”.

The starting point for IWM researchers Wolfgang Körner, Georg Krugel, and Christian Elsässer was a neodymium-iron-nitrogen compound based on a type of...

Im Focus: Atomic precision: technologies for the next-but-one generation of microchips

In the Beyond EUV project, the Fraunhofer Institutes for Laser Technology ILT in Aachen and for Applied Optics and Precision Engineering IOF in Jena are developing key technologies for the manufacture of a new generation of microchips using EUV radiation at a wavelength of 6.7 nm. The resulting structures are barely thicker than single atoms, and they make it possible to produce extremely integrated circuits for such items as wearables or mind-controlled prosthetic limbs.

In 1965 Gordon Moore formulated the law that came to be named after him, which states that the complexity of integrated circuits doubles every one to two...
