Why do we need biomonitoring in Canada?

Biomonitoring is used to measure the levels of pollutants, contaminants or other hazardous elements in our environment and bodies of living organisms so that authorities and environmental groups can better understand our environmental health and safety. Biomonitoring can be used to track levels of particularly hazardous substances, such as heavy metals, pesticides and other potentially toxic substances, allowing us to take necessary steps to reduce exposure and harm. Regular biomonitoring is critical in Canada to understand and report on the effects of pollution on our populations and ecosystems, in order to protect human and environmental health and safety.

How does camera depth of field work?
Camera depth of field (also known as DOF) refers to the range of distance over which objects appear sharp in a photograph. The area of the image in front of and behind the focused distance that appears sharp is known as the depth of field. Depending on the type of camera, lens, aperture setting and other variables, a photographer can affect how much of the image is in focus, allowing them to achieve different artistic effects. A larger depth of field is achieved when a large aperture is used, which creates a shallow depth of field. By narrowing the aperture, the depth of field can be greatly increased. Additionally, by positioning the camera further away from the subject, the depth of field can be increased.
