Harmful chemicals in sewage sludge that is spread on pasture land as fertilizer are causing cancer, the Environmental Protection Agency said Tuesday. The risk is highest for people who regularly consume milk, beef and other products from farms where it is spread.

2025年1月6日 · In the U.S., there are generally three options for use or disposal of sewage sludge: land application, landfilling, and incineration. Land application is the spraying, spreading, incorporation, or injection of sewage sludge into or onto the land to either condition the soil or fertilize crops or vegetation grown in the soil.

Treated sewage sludge, or “biosolids,” are commonly applied to farmlands and sold directly to home gardeners as compost, soil amendment, or fertilizer. We identified at least 30 different commercial fertilizers made from sewage sludge and sold at retailers like Lowe’s, The Home Depot, Ace Hardware, and Menards, and direct from ...

2010年10月4日 · Using sewage sludge – one of two end products from any wastewater treatment plant (the other is effluent) – as fertilizer on food crops is a hotly debated food safety issue, but only among a...

2025年2月16日 · As EPA concedes, its assessment understates risks in several ways: by evaluating harm from exposure to just two of at least 23 PFAS chemicals EPA has detected in sewage sludge (see SI Table 3); assuming sludge contains far lower levels of these two PFAS than tests show it does; assessing risk from exposure to one consumable at a time (water ...

2025年1月14日 · Harmful chemicals in sewage sludge spread on pasture as fertilizer pose a risk to people who regularly consume milk, beef and other products from those farms, in some cases raising cancer...

2024年7月5日 · Sewage sludge fertilizer presents a valuable opportunity to sustainably manage waste sewage sludge while also has application in intensive farming as it can improve soil health and condition by supplying essential nutrient contents such as nitrogen, phosphorus, and potassium offering a substitute for synthetic fertilizers (Muter et al., 2022b ...

2025年1月14日 · Once PFAS-contaminated sludge is applied as a fertilizer, the forever chemicals can leach into food crops, and crops of animal feed, such as corn and hay. Then it can also be absorbed by animals that eat these feed crops. Some PFAS are more likely to …

2018年5月4日 · The present study aims to show the results of 2 years’ sampling of sewage sludge—based on 130 samples collected from 35 wastewater-treatment plants situated in the North of Italy—and to assess its suitability as soil fertilizer regarding contents of nonylphenol (NP), nonylphenolethoxylates (NPnEOs), and phthalates (DEHP).

2022年3月1日 · Organo-mineral fertilizer production based on sewage sludge is a promising solution for solving the problem of sludge management for wastewater treatment plants with a low level of industrialization.
