chemical stabilization of heavy metals is one of the soil remediation methods based on the application amendments to reduce mobility of heavy metals. a laboratory study was conducted to investigate the influence of different kinds of amendments on cadmium (cd) stabilization in a cd-spiked soil. the amendments were municipal solid waste compost (mswc), coal fly ash (cfa), rice husk biochars prep...
Soil microbial communities under three agricultural management systems (conventionally tilled cropland, hayed pasture, and grazed pasture) and two fertilizer systems (inorganic fertilizer and poultry litter) were compared to that of a w150-y-old forest near Watkinsville, Georgia. Both 16S rRNA gene clone libraries and phospholipid fatty acid (PLFA) analyses indicated that the structure and comp...
Background and Objective: Heavy metals fixation in-situ by using inorganic amendments is a method for immobilization of polluted soils. The goal of this research was to determine efficiency of five amendments for heavy metals fixation of waste-water-irrigated soils around Tabriz city. Materials and Methods: Cadmium, Pb, Cu, Ni, and Zn- containing solutions were added to 0.5 gram of five amendm...
The Clean Air Act Amendments of 19901 ("Amendments") transform the federal statute which regulates air pollution into a behe-moth of over 700 pages in length. The Amendments add substantial new requirements to the Clean Air Act of 1970,2 as previously amended in 1977. 3 Even a cursory review of the Amendments demonstrates that their requirements will affect the cost and availability of many con...
This article examines New York City’s first attempt to regulate adult entertainment establishments through zoning provisions. Specifically, it discusses whether the adult-use zoning provisions comply with federal and state constitutional requirements, and it examines whether the adult-use amendments would cause a reduction in adult-use establishments in New York City, which would render the ame...
an experiment was conducted to evaluate the effect of chemical amendments and reused litter on broiler performances, immune response and skin quality. five hundred and seventy six (576) day old broiler chickens were randomly allocated to 3x2 factorial design experiment. three amendments treatment included control (no chemical addition), alunminum sulfate and zeolite; two types of litter were ne...

the purpose of this research was to evaluate the effects of litter chemical amendments on litter quality, broiler performance and carcass lesions (breast blisters, foot pad lesions and hock burns). in a 2×4 factorial experiment with 576 commercial broiler chicks (arian), the effect of two types of litter materials and three amendments were investigated using a completely randomized design with ...
The influence of pH on the sorption of pentachlorophenol (PCP) onto three organic amendments, char, humic acid (HA) and peat, and the effect of organic amendments on PCP sorption to three kinds of soils were evaluated. The sorption of PCP on these sorbents fitted the Freundlich model well, suggesting that PCP sorption isotherms were nonlinear with exponential coefficient (N) value lower than 1....
Soil amendments play an important role in management of pesticide residues. In this study, incubation experiment was conducted using the surface (0 15 cm) sample of a mollisol supplied with different soil amendments (farmyard manure, cow-dung slurry, pyrite and gypsum) to investigate the effect of amendments on the dissipation of lindane in mollisols. Dissipation of lindane in soil was studied ...
