All palms present ornamental appeal and may be widely used in landscaping, especially the native ones because of their ecological importance, such as jussara palm (Euterpe edulis Mart.). In this sense, aiming at maximum plant development urban environment, it is necessary to use high-quality seedlings; substrate one key factors that directly influence it. The objective study was evaluate initia...

Leaching of arsenic (As) from chromated copper arsenate (CCA)-treated wood may elevate soil arsenic levels. Thus, an environmental concern arises regarding accumulation of As in vegetables grown in these soils. In this study, a greenhouse experiment was conducted to evaluate As accumulation by vegetables from the soils adjacent to the CCA-treated utility poles and fences and examine the effects...

ABSTRACT Substrate composition is a major factor influencing seedling quality. This study aimed to evaluate the potential of biosolid as substrate component in initial growth Syagrus romanzoffiana (Cham.) Glassman seedlings. The experimental design was completely randomized, with six treatments, five replicates and seven plants per plot. treatments consisted substrates resulting from mixture su...

Helminth ova (HO) are the main biological concern when reusing sludge for agricultural production. Worldwide sludge regulations consider a permissible range of 0.25-1 HO/gTS. Such limits are unaffordable to most developing countries, due to high helminth ova content in sludge, and the lack of viable technology to inactivate them as needed. The quantitative microbial risk assessment (QMRA) is a ...

Abstract Land-applied municipal biosolids, produced from wastewater treatment sludge, contributes to microplastics contamination in agroecosystems. The impacts of biosolids on microplastic concentrations agricultural soil have been previously investigated, however, the potential for transport biosolid-amended croplands has not quantified. In this study, manure and were applied field plots, runo...

Introduction The use of biosolids from wastewater treatment plants in agriculture is considered relevant for the promotion sustainable agricultural practices, improvement soil fertility, and reduction dependence on synthetic chemical products. Dominican Republic today world's largest producer organic bananas main exporter fair-trade to Europe. generated currently have no use. In other countries...

Nonylphenol (NPs) and nonylphenol ethoxylates (NPEOs) enter the environment during the course of land-application of sewage sludge (biosolids). These xenoestrogens have been previously reported in biosolids at concentrations as high as parts per thousand, g/kg (dry weight). Here we examine their residence time and potential for migration during runoff events from pasturelands that received bios...

Conventional wastewater treatment generates large amounts of organic matter-rich sludge that requires adequate treatment to avoid public health and environmental problems. The mixture of wastewater sludge and some bulking agents produces a biosolid to be composted at adequate composting facilities. The composting process is chemically and microbiologically complex and requires an adequate aerat...
