Clint, magic, dishwasher, sponge wipe formaldehyde is really harmful to the human body?

My opinion is as follows:

1: For these east, there should be no standard inside the national standard, stainless steel spongeand its raw materials contain formaldehyde precursors, if the process is not up to standard, they will inevitably continue to release formaldehyde, resulting in a certain range of formaldehyde concentration. However, if it is packed in a very small closed box to measure the air in the box is not exceeding the standard, which belongs to Zhang Guanli, forcing it to put a cap with formaldehyde exceeding the standard. Any similar product will generally release a certain amount of formaldehyde, the key is the speed of its release and the length of the release. If you follow the method in the video, basically any related product can reach the conclusion of exceeding the standard, after all, in a small enough space and a long enough time range, the formaldehyde released can always reach a high concentration after all. Leaving the detection space and accumulating time to talk about exceeding the standard is rogue.

2: These erasers are generally used for washing tableware or chopsticks or writing on the blackboard. The human body does not have much contact time, and direct contact with the skin generally does not cause formaldehyde to enter the human body and cause harm. Formaldehyde acts on human body mainly through breathing into alveoli to further produce toxic effects. If the eraser is inferior and used for a long time (for example, the teacher has been holding it in his hand), the formaldehyde emitted may cause the local concentration to be too high, which is harmful to the human body.

3: the volume and quality of these erasers are relatively small, the total amount of formaldehyde precursor will not be too high, the impact of the release of the scope will be relatively small, as long as the place placed well ventilated, generally will not cause indoor formaldehyde concentration is too high. Relatively speaking, the poor quality of home decoration because of the volume, release speed, easy to cause indoor formaldehyde concentration is too high, thus endangering human health.

Overall conclusion, long-term contact with (teachers) may cause certain harm, only short-term contact (washing dishes) will not cause harm, and these people are unlikely to be the chief culprit of indoor air formaldehyde pollution, and the ubiquitous indoor inferior home improvement is our main concern.
