Land Application of Biosolids in the USA: A Review
نویسندگان
چکیده
Land application of biosolids has proven a cost-effective method of waste disposal by beneficially recycling organic matter and nutrients and improving soil quality; however, it may also pose potential threat to the environment and human health. The purpose of this paper is to provide information on recent research progresses and regulation efforts regarding land application of biosolids, including forms and types and nutrient values of biosolids, environmental and health concerns, and related best management practices (BMPs) of biosolids application, with emphasis on its land application in agriculture. More research and regulations are expected to minimize potential risks of biosolids land application, especially its long-term impacts.

متن کاملThe SLEUTH Land Use Change Model: A Review
Land use change is driven by interaction in space and time between humans and the environment that can be captured by computer simulation models (Veldkamp and Verburg, 2004). In the last few decades, land use change models have played an important role in understanding the causes, mechanisms and consequences of land use dynamics. SLEUTH is an open source cellular automata based land use change ...
متن کاملEffect of Long-Term Application of Biosolids on Molybdenum Content and Quality of Winter Wheat Forage
Forages that accumulate excessive molybdenum (Mo) from excessive land application of Mo can cause molybdenosis, a copper (Cu) induced deficiency in ruminants. Limited information is available on the effect of land-applied biosolids, Mo content, and quality of winter wheat forage (Triticum aestivum L.). The objectives of this study were (1) to determine the effect of biosolids application on tis...
متن کاملToward a consensus view on the infectious risks associated with land application of sewage sludge.
The science linking processed sewage sludge (biosolids) land application with human health has improved in the last ten years. The goal of this review is to develop a consensus view on the human health impacts associated with land-applying biosolids. Pre-existing risk studies are integrated with recent advances in biosolids pathogen exposure science and risk analysis. Other than accidental dire...
متن کاملSurvival, Growth, and Regrowth of Enteric Indicator and Pathogenic Bacteria in Biosolids, Compost, Soil, and Land Applied Biosolids
MILLIONS of dry tons of biosolids are produced every year. Recycling of them and the safety of disposal is an issue at the center of a national debate. Due to the nutrient content of biosolids, they can be reused beneficially as a soil amendment on numerous areas, such as parks, forests, and agricultural land [41]. Biosolids can also be sold in bulk to consumers for use on home gardens or lawns...
