tap water from a given well, the detected concentrations should be compared with regulatory thresholds for allowable levels of arsenic in drinking water. If the detected levels are consistently lower than these limits, arsenic may not be a chemical of potential concern for the purposes of this risk assessment. When interpreting hazard data, risk assessors must consider the sensitivity of the instrument and method used to take these measurements, including any relevant detection limits (i.e., the lowest level of a given substance that an instrument or method is capable of detecting).
210:, also known as biohazards, are organic substances that pose a threat to the health of living organisms, primarily humans. This can include medical waste, samples of a microorganism, virus, or toxin (from a biological source) that can impact human health. Biological hazards can also include substances harmful to animals. Examples of biological hazards include bacteria, viruses, fungi, other microorganisms and their associated toxins. They may cause a myriad of diseases, from flu to more serious and potentially fatal diseases.

Persistence towards these elimination mechanisms combined with toxicity gives the substance the ability to do damage in the long term. Also, the lack of immediate human toxicity does not mean the substance is environmentally nonhazardous. For example, tanker truck-sized spills of substances such as

Hazards have the potential to cause adverse effects only if they come into contact with populations that may be harmed. For this reason, hazard identification includes the development of a conceptual model of exposure. Conceptual models communicate the pathway connecting sources of a given hazard to

Once a conceptual model of exposure is developed for a given hazard, measurements should be taken to determine the presence and quantity of the hazard. These measurements should be compared to appropriate reference levels to determine whether a hazard exists. For instance, if arsenic is detected in

Psychological hazards can exist in any type of workplace, and their management is a crucial aspect of occupational health and safety.
