The synthesis of chemical substances has resulted in technological benefits for society and has also caused increased chemical exposures and risks of related cancers. Although progress has been made in cancer treatment, there has been little improvement in real survival time for people who develop the major forms. Therefore, the need to prevent cancer is paramount. The greatest chemical exposures and risk of associated preventable cancers are found in the workplace, but generally environmental exposures receive greater public attention. Chemical causes of cancer have been identified, and in some cases decades have passed before controls have been adequately instituted. Some companies show a high regard for worker health, while others may minimize or misrepresent the hazards to exposed workers. Medical personnel receive relatively little education in the recognition of industrially related diseases. Workers are often unaware of their risks or are trapped in jobs because of economic necessity, and government has been slow to regulate, in part because of lobbying efforts. Experience has shown that when chemicals are regulated relatively soon after they are identified as hazardous, lives are saved, and the industry is economically healthy; however, when regulation is delayed, thousands of people die unnecessarily, and the cost to industry and society are phenomenal. Society has the opportunity to apply the knowledge learned from these experiences as we address current problems of chemical pollution.
化学物质的合成给社会带来了技术效益,但也导致了化学暴露增加以及相关癌症风险上升。尽管癌症治疗取得了进展,但对于罹患主要癌症类型的患者而言,实际生存时间几乎没有改善。因此,预防癌症的需求至关重要。在工作场所发现了最大程度的化学暴露以及相关可预防癌症的风险,但一般而言,环境暴露受到了公众更多关注。癌症的化学成因已得到确认,在某些情况下,几十年后才充分实施控制措施。一些公司高度重视工人健康,而另一些公司可能会淡化或歪曲对接触工人的危害。医务人员在识别与工业相关疾病方面接受的教育相对较少。工人往往意识不到自己面临的风险,或者由于经济需要而被困在工作岗位上,而且政府监管行动迟缓,部分原因是受到游说活动的影响。经验表明,当化学物质在被认定为有害后相对迅速地受到监管时,就能挽救生命,行业也能保持经济健康;然而,当监管延迟时,成千上万的人会不必要地死亡,行业和社会付出的代价将是巨大的。在我们应对当前化学污染问题时,社会有机会运用从这些经验中学到的知识。
