What is Toxicology?

Toxicology is the scientific study of poisons and the harmful effects they have on living organisms, including humans. It involves identifying and characterizing toxic substances, assessing their potential risks, and developing strategies to prevent or mitigate their impact on health and the environment.

  1. WHAT IS TOXICOLOGY?

  2. Toxicologyisafieldofsciencethathelps us understand the harmful effects that chemicals,substances,orsituations,can have on people, animals, and the environment. Some refer to toxicology as the “Science of Safety” because as a field it has evolved from a science focused on studying poisons and adverseeffectsofchemicalexposures,to a science devoted to studying safety. (n.d.)

  3. OCCUPATIONAL DISEASESINTHE WORKPLACE Toxicology is intrinsically related to occupational diseases. Many workers develop occupational diseases due to long-term exposure to chemicals, radioactivematerials,andotherharmfulsubstances. As such, today’s workers are better safeguarded from toxic substances in the workplace. However, progress has also brought about new occupational diseases and hazards, and exposed workers to new types of toxic gases, chemicals, and other substancesthathavebeendiscoveredorman-made over the years. These newly emerging toxins continuetoplagueworkerscausingnewhealthrisks and health effects even as state-of-the-art techniques are used to analyze the effect of these chemicalsonhumanhealth.

  6. OSHA AND TOXICOLOGY Accordingly, OSHA has developed OccupationalExposureLimits(OELs)for different air-borne toxins related to a range of occupations, industries, chemicals, and toxic substances. While stipulating Permissible Exposure Limits (PELs)whicharebasedon8-hourtime- weighted averages (TWA), OSHA also specifies Ceiling and Peak limits which must be compulsorily adhered to by employers. While many of the details are available in the applicable sections of the General Industry, Construction, Shipyard Employment, Marine Terminals, and Longshoring regulatory standards, the most up-to-date informationisavailableasanAnnotated Table.
