有研究指出,在美国加州,由于人造板及其制品的大量使用,从中释放的甲醛数量每年约900 t,严重影响了环境和人类健康。早在1992年,美国加州空气资源委员会(California Air Resources Board,CARB)就已确认,甲醛是有毒的空气污染物,且是一种致癌物质。2002年,加州政府对人造板及其制品的甲醛释放量进行了大量调查和研究,结果显示,加州户外空气中游离甲醛的含量为3~4μg/m~3,室内则更高。研究还表明:每百万人口中,如果在高甲醛
Some studies have pointed out that in California, the amount of formaldehyde released from wood-based panels and their products is about 900 tons per year due to the heavy use of wood-based panels and their products, seriously affecting the environment and human health. As early as 1992, the California Air Resources Board (CARB) has confirmed that formaldehyde is a toxic air pollutant and a carcinogen. In 2002, the California government conducted extensive investigations and studies on the formaldehyde emission of wood-based panels and their products. The results showed that the content of free formaldehyde in outdoor air of California was 3 ~ 4μg / m ~ 3, and the interior was even higher. The study also shows that: per million people in the high formaldehyde
