Malignant neoplasm of the bladder - Inhaling air containing PAHs Factor

RMA definition

Polycyclic aromatic hydrocarbons (PAHs) are hydrocarbons with three or more condensed aromatic rings in which certain carbon atoms are common to two or three rings. A common example is benzo[a]pyrene. Polycyclic aromatic hydrocarbons occur in crude oil, shale oil, and coal tars, and can be formed during the combustion of organic material or during high temperature processing of crude oil, coal, coke, or other industrial carbon compounds.

SOP Requirements

For the purposes of the SOP the minimum concentration of PAHs in the air must be 0.2mg/m3.  This is a very high concentration level well beyond that which would be permissible under normal workplace health and safety provisions.  Such concentrations would result in visible pollution and might occasionally occur, for example, within an enclosed vehicle workshop, when diesel exhaust fumes leak into a closed APC, or as a result of the oil fires during the first Gulf War.

PRELIMINARY QUESTIONS [11712]

11745 there is some evidence that inhaling air containing polycyclic aromatic hydrocarbons may be a factor in the development of the condition under consideration.

11746 the veteran has inhaled air containing polycyclic aromatic hydrocarbons at a concentration of at least 0.2 mg/m3 at some time.

11749  the veteran has established the causal connection between inhaling air containing polycyclic aromatic hydrocarbons and VEA service for the clinical onset of malignant neoplasm of the bladder.

11750   the veteran has established the causal connection between inhaling air containing polycyclic aromatic hydrocarbons and operational service for the clinical onset of malignant neoplasm of the bladder.

or

11751   the veteran has established the causal connection between inhaling air containing polycyclic aromatic hydrocarbons and eligible service for the clinical onset of malignant neoplasm of the bladder.

CLINICAL ONSET AND OPERATIONAL SERVICE [11750]

11880 the veteran has inhaled air containing polycyclic aromatic hydrocarbons at a concentration of at least 0.2 mg/m3 for a cumulative period of at least 5000 hours at some time.

11752 the veteran inhaled air containing polycyclic aromatic hydrocarbons at a concentration of at least 0.2 mg/m3 for a cumulative period of at least 5000 hours before the clinical onset of the condition under consideration.

11747 operational service made a material contribution to the veteran inhaling air containing polycyclic aromatic hydrocarbons at a concentration of at least 0.2 mg/m3 for a cumulative period of at least 5000 hours before the clinical onset of the condition under consideration.

CLINICAL ONSET AND ELIGIBLE SERVICE [11751]

11881 the veteran has inhaled air containing polycyclic aromatic hydrocarbons at a concentration of at least 0.2 mg/m3 for a cumulative period of at least 10000 hours at some time.

11754 the veteran inhaled air containing polycyclic aromatic hydrocarbons at a concentration of at least 0.2 mg/m3 for a cumulative period of at least 10000 hours before the clinical onset of the condition under consideration.

11748 eligible service made a material contribution to the veteran inhaling air containing polycyclic aromatic hydrocarbons at a concentration of at least 0.2 mg/m3 for a cumulative period of at least 10000 hours before the clinical onset of the condition under consideration.
