A review of properties, occurrence, fate, and transportation mechanisms of contaminants of emerging concern in sewage sludge, biosolids, and soils: recent advances and future trends

Frontiers in Environmental Chemistry
Treated sewage sludge, or biosolids, are used worldwide to improve soil quality and fertility due to their high organic matter content and micro- and macronutrients. However, biosolids also introduce contaminants into the environment.

Concentration of Mestranol in Wastewater using High-Performance liquid chromatography

, 2019
A prevalent estrogen found in oral contraceptives, such as birth control, is the estrogen mimic mestranol. Mestranol has been found to have a negative impact on the environment and is causing an increase in the feminization of fish.

THE EFFECTS OF A CHEMOSTERILANT (MESTRANOL) ON POPULATION AND BEHAVIOR IN THE RICHARDSON\u27S GROUND SQUIRREL (\u3ci\u3eSpermophilus richardsonii\u3c/i\u3e) IN ALBERTA

, 1974
A chemosterilant, mestranol, was administered to three populations of Richardson\u27s ground squirrel in southeastern Alberta. Mestranol was given to all squirrels in one plot, to only 50 percent in another plot, while a third plot remained as control ...
