Atrazine
type: Concept
type: Entity
definition: [ChEBI] A diamino-1,3,5-triazine that is 1,3,5-triazine-2,4-diamine substituted by a chloro group at position 6 while one of hydrogens of each amino group is replaced respectively by an ethyl and a propan-2-yl group.
definition: [Wikipedia] Atrazine is a herbicide of the triazine class. It is used to prevent pre-emergence broadleaf weeds in crops such as maize (corn) and sugarcane and on turf, such as golf courses and residential lawns. Atrazine's primary manufacturer is Syngenta and it is one of the most widely used herbicides in the United States and Australian agriculture.As of 2001, atrazine was the most commonly detected pesticide contaminating drinking water in the U.S. Studies suggest it is an endocrine disruptor, an agent that can alter the natural hormonal system. However, in 2006 the U.S. Environmental Protection Agency (EPA) had stated that under the Food Quality Protection Act "the risks associated with the pesticide residues pose a reasonable certainty of no harm", and in 2007, the EPA said that atrazine does not adversely affect amphibian sexual development and that no additional testing was warranted. EPA's 2009 review concluded that "the agency's scientific bases for its regulation of atrazine are robust and ensure prevention of exposure levels that could lead to reproductive effects in humans". However, in their 2016 Refined Ecological Risk Assessment for Atrazine, it was stated that "it is difficult to make definitive conclusions about the impact of atrazine at a given concentration but multiple studies have reported effects to various endpoints at environmentally-relevant concentrations." EPA started a registration review in 2013.The EPA's review has been criticized, and the safety of atrazine remains controversial. Its use was banned in the European Union in 2004, when the EU found groundwater levels exceeding the limits set by regulators, and Syngenta could not show that this could be prevented nor that these levels were safe.

definition
definition: A statement or formal explanation of the meaning of a concept.
sub property of: note

is in scheme
definition: Relates a resource (for example a concept) to a concept scheme in which it is included.

preferred label
comment: A resource has no more than one value of skos:prefLabel per language tag, and no more than one value of skos:prefLabel without language tag.
comment: The range of skos:prefLabel is the class of RDF plain literals.
comment: skos:prefLabel, skos:altLabel and skos:hiddenLabel are pairwise disjoint properties.
definition: The preferred lexical label for a resource, in a given language.
sub property of: label

has broader
comment: Broader concepts are typically rendered as parents in a concept hierarchy (tree).
definition: Relates a concept to a concept that is more general in meaning.
sub property of: broaderTransitive

has exact match
comment: skos:exactMatch is disjoint with each of the properties skos:broadMatch and skos:relatedMatch.
definition: skos:exactMatch is used to link two concepts, indicating a high degree of confidence that the concepts can be used interchangeably across a wide range of information retrieval applications. skos:exactMatch is a transitive property, and is a sub-property of skos:closeMatch.
sub property of: closeMatch
