Despite the increasing industrial use of indium-tin oxide (ITO) to
manufacture flat-panel displays, such as liquid-crystal displays or plasma
display panels for televisions, little is known about the potential health
hazard induced by occupational exposure to indium compounds.
我想問一下，這句是說
「儘管因為平面顯示器的加工使ITO的用量漸增...(逗號間略)」
然後怎樣「銦化物的職業暴露會導致潛在的健康危害」呢？
是指後面這句鮮為人知嗎？

應該是對它所知甚少

is known = 被動句

你想成people know little about會比較容易理解這在學術文章是很常見的，一種逃避的寫法。因為用people就該死了，先下五百字的操作定義！

感謝樓上 這麼說我就懂了～

because that's what i'm doing now...
