Fire is a significant environmental perturbation to forests where vegetation transforms from biomass to ash, potentially releasing stored chemical elements to soils. While much research acknowledges variation in ash composition among different vegetation types (grasses, trees, shrubs and vines), less has focused on interspecific variation among trees and the elemental influx soils receive. Therefore, this research sets out to: (1) identify major, trace, and rare earth element (REE) concentrations by inductively coupled plasma mass spectroscopy (ICP-MS) in ash derived from fifteen tree species, (2) determine likely elemental enrichment to post-fire soils, and (3) assess variability in ash chemistry and color …

Polluted urban runoff as a primary non-point pollution source poses a serious threat to urban human and ecological health. Various urban runoff pollutants challenge the exiting stormwater treatment systems. To support the development of a sound and sustainable urban stormwater management, this dissertation targets at transforming a common landscaping practice, i.e. mulching, into a new stormwater treatment technology through coating aluminum water treatment residual (Al-WTR) on the surface of wood mulch chips. WTR is an industrial waste produced from drinking water treatment plants and primarily comprises amorphous aluminum (hydr)oxides. The Al-WTR coating on the modified wood mulch enables the adsorption …

AMF are symbionts to a majority of terrestrial plants and can improve plant nutrient uptake, water relations, and stress tolerance. This study evaluated the effects of AMF in heavy metal contaminated soils via a growth chamber experiment to determine the interactions between soil and arbuscular mycorrhizal fungi (AMF) affecting plant growth. Rye grass was grown in two contaminated soils from Liberty State Park, an urban brownfield, and one non-contaminated commercial soil, to which half of the treatments received AMF inoculum. Dried plant biomass, root:shoot ratio, and soil phosphatase activity were measured at the completion of the experiment. Soil contamination was …
