Bioremediation of Petroleum Hydrocarbons in Cold Regions by Dennis M. Filler, Ian Snape, David L. Barnes

By Dennis M. Filler, Ian Snape, David L. Barnes

This sensible consultant to bioremediation in chilly areas is designed to help environmental practitioners, undefined, and regulators within the remediation of petroleum spills and infected websites in chilly areas. Remediation layout and know-how utilized in temperate climates doesn't inevitably paintings in chilly climates, and cleanup takes longer because of shorter remedy seasons, sub-freezing temperatures, flooring freezing and thawing, and restricted bioactivity. Environmental engineers and scientists from 8 international locations operating within the polar areas mix their reviews and services with petroleum infection to jot down this e-book. It includes in-depth discussions on laws, freezing and frozen flooring, id and variations of cold-tolerant micro organism, contaminant delivery in chilly soils and permafrost, temperature results on biodegradation, analytical tools, treatability reports, and dietary necessities for bioremediation. Emphasis is given to useful and powerful bioremediation tools for program in chilly areas. rising applied sciences also are mentioned.

G For Canada, the petroleum hydrocarbon range is >C16 . action is deemed to be more damaging than the release itself. Canada, Finland, Norway, and Sweden do not have soil quality guidelines specific to their Arctic regions, although they are all attempting to accommodate Arctic-specific factors in their guidelines. Greenland and Iceland also do not have soil quality regulations for land-based petroleum-contaminated sites. 2. These values are generally environmental investigation guidelines (also known as trigger values), but are often used as remediation targets (frequently referred to as ‘‘magic” numbers) (cf.

2006; Waterhouse and Roper-Gee 2002). Many spills under the jurisdiction of the US program are partly documented (Kennicutt 2003; Klein et al. 2006), although some have been more fully evaluated, have been remediated, and are well documented (Christensen and Shenk 2006; Kennicutt 2003). The 2003 report on human disturbance at McMurdo Station (by far the largest 9 10 I. Snape, L. Acomb, D. L. Barnes, et al. station in Antarctica) noted 385 spills between 1991 and 2000, mostly of JP8, totalling ∼80 000 l.

25 26 I. Snape, L. Acomb, D. L. Barnes, et al. For all sites, the collection of soil samples, the measurement of soil properties, and the determination of various site characteristics can easily be obtained and used to re-calculate remediation criteria quantitatively for a Tier 2 adjustment. However, the issue considered by researchers at Queens University concerned the qualitative attribution of ‘‘importance,” especially whether the soil ecosystem in the area is important (ecological soil contact pathway), whether nutrient cycling might be significant if it was investigated as part of a Tier 3 investigation, and assigning a degree of significance to localized and transient surface water sheen.
