Source-derived summary

Karen Ann Kidd (born 1968) is a Canadian aquatic ecotoxicologist. She is the Jarislowsky Chair in Environment and Health and Professor of Biology at McMaster University and member of the International Joint Commission.

Early life and education

Kidd was born in 1968 in Sarnia, Ontario to parents Diane and George Werezak. Growing up, she attended Cathcart Boulevard Public School and Northern Collegiate Institute and Vocational School, where she graduated from in 1987. She earned her Bachelor of Science degree in Environmental Toxicology from the University of Guelph and her PhD in Biology from the University of Alberta.

Career

Upon completing her PhD, Kidd became a Research Scientist in the Environmental Sciences Division at Fisheries & Oceans Canada. In 2002, Kidd was the recipient of the Queen Elizabeth II Golden Jubilee Medal. During her tenure with Fisheries and Oceans Canada, Kidd began surveying the minnows in a 34-hectare lake in Ontario. Her research team found that male fish who were swimming in oestrogen-laced water would become intersex and lose the ability to breed. Later, she found that estrogen in municipal water systems nearly led to the extinction of the fathead minnow.

Editorial analysis

Why this record matters

The subject matters to the general reference register because the source frames it as canadian aquatic ecotoxicologist. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Apr 5, 2026. The linked authority identifier is Q41554355. VIAF identifies the subject as 4748893. The Library of Congress control number is no2008112549. 1 of 3 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1968, 1987 and 2002.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it
