A petroleum refinery site has soil contaminated with Benzene (a Carcinogen). Exposure concentration in soil is 3.7 mg/kg. A worker weighing 75 kg works for five days a week on the site. The worker ingests soil at the rate of 150 mg/day, which is 69% contaminated with soil from the site for an exposure duration of 1 year. The risk for Benzene (Slope factor = 1.5 × 10^(-2) kg-day/mg)
Answers
The risk of benzene will be 2.4.
This toxicological profile is prepared per recommendations evolved with the aid of the organization poisonous materials and disorder Registry (ATSDR) and the Environmental safety organization (EPA) are as follows-:
1) Authentic recommendations were published in the Federal sign-up on April 17, 1987. Every profile may be revised and republished as necessary.
2)The ATSDR toxicological profile succinctly characterizes the toxicologic and unfavorable fitness results data for the risky substance defined therein. Each peer-reviewed profile identifies.
3) And critiques the critical literature that describes a dangerous substance's toxicologic residences. Other pertinent literature is likewise supplied, however,
4) is described in much fewer elements than the essential thing studies. The profile isn't always supposed to be an exhaustive file; however, more of an excellent comprehensive resource of strong point records.
5) The point of interest of the profiles is on health and toxicologic records; therefore, each toxicological
6)The profile starts evolved with a public health statement that describes, in nontechnical language, a substance's
7)Relevant toxicological homes. Following the public fitness statement are statistics regarding the range of widespread human exposure and, in which acknowledged, tremendous health effects. The adequacy of the information
8)To determine a substance's fitness effects is described in a fitness effects summary. Statistics needs that are of significance to the protection of public fitness are identified by using ATSDR and EPA.
