Dialectal Variation
British vs American Usage
Differences
No lexical differences; the term is identical in spelling and reference. Regulatory discussions may reference different agencies (e.g., UK Environment Agency vs US EPA).
Connotations
Predominantly negative connotations related to environmental contamination and regulatory bans/restrictions in both varieties, though specific legal statuses differ.
Frequency
Equally low in general discourse but slightly higher frequency in American English due to the scale of corn (maize) cultivation and related legal debates.
