Table schema:
CREATE TABLE table_name_62 (type VARCHAR, averaging_time VARCHAR, standard VARCHAR)

Question: what is the type when the averaging time is 1-hour and the standard is 0.12 ppm (235 μg/m³)?
SQL: SELECT type FROM table_name_62 WHERE averaging_time = "1-hour" AND standard = "0.12 ppm (235 μg/m³)"
