Answer:
Explanation:
Endocrine disruptors (EDCs): These are chemicals that can interfere with endocrine or hormonal systems by altering hormone levels, affecting the synthesis or metabolism of hormones or by changing the way hormones elicit their functions. These disruptions may lead to cancerous tumors, birth defects and other developmental disorders in humans. EDCs are also naturally occurring or man made chemicals that are released into the environment. Humans are exposed to EDCs through ingestion, inhalation or direct contact through skin. Wildlife are exposed to EDCs through food and water consumption. Examples of EDCs are pesticides (e.g., atrazine and vinclozolin) and surfactants (e.g., octyphenol).
Why these chemicals have not been banned by the United State government is because some of them are of economical importance. Example is BPA, which is one of the most high production volume chemicals in the world and these chemicals are widely used in so many products and its very difficult to banned.
