Final answer:
Correct handling of pesticide containers requires triple rinsing and disposing of them at an approved landfill or recycling event, but not repurposing them for other uses because of contamination risks.
Step-by-step explanation:
Proper handling of pesticide containers involves certain necessary steps to prevent environmental pollution and health hazards. Triple rinsing of containers is critical to remove most of the remaining pesticides, ensuring that traces of these chemicals do not contaminate the environment when the containers are discarded or repurposed. Rinsed containers should then be taken to an approved landfill for disposal, or to a pesticide container recycling event, rather than being reused for other purposes which could pose a risk to health and safety. Therefore, the correct answer to the question is 'd, both a and c'. It's important to note that recycling or reusing pesticide containers for other purposes, like as water or oil jugs or floatation devices, is not recommended due to the risk of residual contamination.
