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.
我想问一下，这句是说
“尽管因为平面显示器的加工使ITO的用量渐增...(逗号间略)”
然后怎样“铟化物的职业暴露会导致潜在的健康危害”呢？
是指后面这句鲜为人知吗？

应该是对它所知甚少

is known = 被动句

你想成people know little about会比较容易理解这在学术文章是很常见的，一种逃避的写法。因为用people就该死了，先下五百字的操作定义！

感谢楼上 这么说我就懂了～

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