As a common plasticizer in plastic products, it can migrate from plastic products to the environment or food, and widely exists in the environment. Phthalates can be detected in air, water and food. The human body can ingest such substances through the environment, diet, drinking water and other channels.

However, trace plasticizer has no obvious effect on human health. Animal experiments show that the trace plasticizer in monkeys can be excreted by metabolism within 24 hours to 48 hours.

The allowable daily intake of plasticizer DEHP stipulated by the World Health Organization is 0.025mg/kg. That is to say, if a person weighing 60 kg ingests 1.5 mg to 8.5 mg of plasticizer every day for life, it may cause obvious health damage.

Extended data

Plasticizers are everywhere, but for ordinary consumers, some effective measures can be taken to reduce the harm of plasticizers in daily life.

1. Avoid using plastic food containers and replace them with stainless steel, glass and ceramics. If you must use plastic food containers, you should choose plastic products that have been tested and have almost no plasticizer dissolved when heating, and mark them as "microwave-heatable".

2. Avoid long-term contact or immersion between food and plastic containers, and reduce the dissolution of plasticizer. Thirdly, the plastic wrap and plastic bag for food preservation should use PE and PVDC without plasticizer, and avoid high temperature heating.

3. When you need to heat food with plastic wrap or plastic wrap, poke a few small holes in the plastic wrap (plastic wrap) to let the gas out. In addition, the solubility of plasticizer in water is very small, and the amount of plasticizer dissolved in oil is very large. It is necessary to avoid the contact between oil and plastic products and avoid the dissolution of plasticizer.
