Textile fibers have been studied in both indoor and outdoor environments to determine the average human exposure. The indoor concentration was found to be 1.0–60.0 fibers/m^3, whereas the outdoor concentration was much lower at 0.3-1.5 fibers/m^3. The deposition rate indoors was 1586-11,130 fibers per day/m^3 which accumulates to around 190-670 fibers/mg of dust.The largest concern with these concentrations is that it increases exposure to children and the elderly, which can cause adverse health effects.

Textile fibers have been studied in both indoor and outdoor environments to determine the average human exposure.
テキスタイルファイバーは、屋内および屋外の両方の環境で研究され、人間の平均暴露量が決定されています。

The indoor concentration was found to be 1.0–60.0 fibers/m^3, whereas the outdoor concentration was much lower at 0.3-1.5 fibers/m^3.
屋内濃度は1.0〜60.0ファイバー/ m ^ 3であることがわかりましたが、屋外濃度は0.3-1.5ファイバー/ m ^ 3ではるかに低くなりました。

The deposition rate indoors was 1586-11,130 fibers per day/m^3 which accumulates to around 190-670 fibers/mg of dust.
屋内での堆積速度は、1日あたり1586〜11,130繊維/ m ^ 3で、約190〜670繊維/ mgのダストが蓄積しました。

The largest concern with these concentrations is that it increases exposure to children and the elderly, which can cause adverse health effects.
これらの濃度に関する最大の懸念は、健康への悪影響を引き起こす可能性のある子供や高齢者への曝露が増加することです。
