benzo a pyrene in soil
Benzo(a)pyrene, a polycyclic aromatic hydrocarbon (PAH), is commonly detected in soil and sediment due largely to its anthropogenic presence as a by-product of incomplete
Benzo(a)pyrene can enter the body either by inhalation of air containing benzo(a)pyrene, ingestion of water or food containing benzo(a)pyrene, or by dermal contact with benzo(a)pyrene, contaminated soil or products containing benzo(a)pyrene. Inhalation of benzo…
Benzo [a]pyrene in soils and ground water: Occurrence, sources, distribution, interrelation. Surface soil layer proved to be an efficient protective barrier against BaP penetration to ground water. Due to different mechanism and dynamics of binding and migration, no correlation between BaP and Fl in water was found, while in soil,

Camp Justice: Benzo(a)pyrene in Soil The Preliminary Public Health Screening Risk Assessment Report, Camp Justice, describes the results of soil samples for benzo(a)pyrene. Benzo(a)pyrene is one compound in a group of over 100 compounds that are called polycyclic aromatic hydrocarbons (PAHs).
In order to validate the use of compost in soil PAH bioremediation, the degradation of anthracene and benzo(a)pyrene was monitored in soils artificially contaminated and incubated in mesocosms under controlled conditions.

Bioaccumulation of benzo[a]pyrene is 0.1% from total concentration in soil. Benzo[a]pyrene spiked soils lead toxic effect on spring barley. Sensitive indicators of benzo[a]pyrene are length of vegetative part and ear height. Benzo[a]pyrene toxic effect depends on its concentration and incubation time in soil.

Benzo[a]pyrene (BaP) is a polycyclic aromatic hydrocarbon found in coal tar with the formula C20H12. The compound is one of the benzopyrenes, formed by a benzene ring fused to pyrene, and is the result of incomplete combustion at temperatures between 300 °C (572 °F) and 600 °C (1,112 °F).
Chemical formula: C₂₀H₁₂
In contrast, there is still a lack of information for subsoils. In this study, we analyze, summarize, and discuss the heavy metal and benzo[a]pyrene contamination patterns of a very large number of rubble-containing soils, topsoils, and natural subsoils in the urban area of Berlin.

However, the availability of such data is very limited. Blumer (1961) reports that benzo( a)pyrene concentrations in Cape Cod, MA, soils range from 0.04 to 1.3 mg/kg. Menzie et al. (1992) report that urban background soil levels of total carcinogenic PAH range from 0.06 to 5.8 mg/kg. Butler et al.
