With the aim of investigating the effects of carbonaceous sorbent amendment on plant health and end point contaminant bioavailability, plant experiments were set up to grow maize (Zea mays) in soil contaminated with polycyclic aromatic hydrocarbons (PAHs) and metals. Maize and pine derived biochars, as well as a commercial grade activated carbon, were used as amendments. Plant growth characteri...

Plants can remove or immobilize various environmental contaminants; however, little is known about the physiological mechanisms underlying responses to soil amendment with biosolids contaminated with heavy metals. We investigated the responses of cuttings of hybrid poplar clones Eridano and I-214 grown for a season in soil amended with nutrient-rich organic material from tanneries, which contai...

We examined the toxicity mitigation efficiency of a hydrologically modified backwater wetland amended with a pesticide mixture of atrazine, metolachlor, and fipronil, using 96 h survival bioassays with Hyalella azteca. Significant H. azteca 96 h mortality occurred within the first 2 h of amendment at the upstream amendment site but not at any time at the downstream site. H. azteca survival vari...

1.1 The evidence for the Lower and Middle Palaeolithic in Northamptonshire has recently been summarised and briefly reviewed as part of the English Heritage sponsored English Rivers Palaeolithic Project (ERPP) (Wessex Archaeology, 1996). This paper has been prepared as part of the East Midlands Regional Research Frameworks Project to provide a brief statement of the current state of knowledge f...
