The purpose of this study was to quantify the occurrence and release of antibiotic resistant genes (ARGs) and antibiotic resistant bacteria (ARB) into the environment through the effluent and biosolids of different wastewater treatment utilities including an MBR (Membrane Biological Reactor) utility, conventional utilities (Activated Sludge, Oxidative Ditch and Rotatory Biological Contactors-RB...

The pending loss of methyl bromide (MBr) and less understood nematode adaptation behaviour present significant challenges in managing Meloidogyne hapla in vegetable and nursery industries in temperate climates. This study examined the reproductive potential of populations of M. hapla from three nursery (Fields 1–3), one vegetable (Field 4) production system, and their response to a nutritionbas...

Triclosan (TCS) is a broad spectrum antibacterial agent present as an active ingredient in some personal care products such as soaps, toothpastes and sterilizers. It is an endocrine disrupting compound and its increasing presence in water resources as well as in biosolid-amended soils used in farming, its potential for bioaccumulation in fatty tissues and toxicity in aquatic organisms are a cau...

Compost use in landscaping and erosion control applications has become widespread. Various types of composts have been utilized on highway embankments for soil conservation and runoff reduction. Different compost materials could have different erosion control effects. The objective of this study is to investigate the erosion resistance of three commonly used composts and their effects on slope ...

A large fraction of engineered nanomaterials in consumer and commercial products will reach natural ecosystems. To date, research on the biological impacts of environmental nanomaterial exposures has largely focused on high-concentration exposures in mechanistic lab studies with single strains of model organisms. These results are difficult to extrapolate to ecosystems, where exposures will lik...

Perennial herbaceous crops can become the main basis for renewable energy production in agricultural ecosystems in future. To determine the plant species that are the most suitable for biomass production, their biological peculiarities and productivity, biochemical composition and thermophysical properties, social and ecological impact must be investigated thoroughly. The local varieties of per...

Application of municipal biosolids (sewage) to agricultural land is a common practice to improve soil physical quality and fertility. The chosen method of land application can have a strong impact on the extent of adjacent water contamination by nutrients and bacteria. Dewatered municipal biosolids (DMB) were applied to silt-clay loam experimental field plots in Ontario, Canada using two applic...

Nitrogen (N) availability affects plant biomass yield and, hence, phytoextraction of contaminants during phytoremediation of end-of-life municipal lagoons. End-of-life lagoons are characterized by fluctuating moisture conditions, but the effects on biosolid N dynamics have not been adequately characterized. This 130-d laboratory incubation investigated effects of three moisture levels (30, 60, ...

The aim of this study was to assess the impact soil amendments, characterized by different sorption properties, on effectiveness trace elements’ (Cu, Zn, Pb, Cd, Ni, and Cr) stabilization bioavailability earthworms. conducted as a microcosm experiment using derived from heavily contaminated post-industrial area. Eisenia veneta earthworm cultured for 4 weeks in soils amended with materials origi...
