The TLV for aldrin in public drinking water supplies is roughly ____________ μg/liter?
Show answer Hide answer
Answer: B. 17
Explanation
Threshold limit value for aldrin pesticide contamination in public drinking water is established near seventeen. Toxicological risk assessments determine these strict concentration limits to protect human health. micrograms per liter represents the standard concentration metric used for trace organic water pollutants. Aldrin is a persistent chlorinated cyclodiene insecticide formerly used widely in agricultural crop protection. Public drinking water standards enforce strict limits because aldrin bioaccumulates in fatty tissues. Regulatory toxicologists establish threshold limit values based on extensive animal and human health studies.
Municipal water treatment plants employ advanced activated carbon filtration to remove trace pesticide residues. Environmental monitoring agencies test rural well water routinely for banned organochlorine pesticide compounds. Protecting public water supplies from chemical contamination prevents chronic long term health disorders. Values like zero point five micrograms per liter underestimate the regulatory threshold established for aldrin. Higher figures such as three hundred fifty seven represent lethal or dangerous industrial exposure levels. Extremely large numbers fail to reflect safe parts per billion drinking water safety regulations.
