An environmentally controlled portable toilet designed to neutralize and confine contaminating agents such as bacteria, odors, vapors and other airborne particles inside the bowl by generating and maintaining a cyclone-type air circulation inside the bowl-structure. A circular shaped bowl-structure (170) with a circular air-trapping cavity created inside the bowl-structure (170) by a seat-skirt (188), confines the contaminating agents during toilet use and improves the efficiency of the air circulation. A removable air-cooling tray 134, and sanitizer and odor conditioner cartridges (131) are employed to cool the air moving inside the air-trapping cavity, and respectively, to neutralize the contaminating agents by releasing sanitizing and odor conditioning agents into the air flow circulated inside the bowl (170). A toilet seat (182) having an ergonomic design has a seat-skirt (188). The invention is applicable to portable toilet systems including children's training toilets.
