电池产品可分一次干电池(普通干电池)、二次干电池(可充电电池,主要用于移动电话、计算机)、铅酸蓄电池(主要用于汽车)三大类.用量最大、群众最关心、报道最多的是普通干电池. 就体积和重量而言,废电池在生活垃圾中是微不足道的,但它的... 电池产品可分一次干电池(普通干电池)、二次干电池(可充电电池,主要用于移动电话、计算机)、铅酸蓄电池(主要用于汽车)三大类.用量最大、群众最关心、报道最多的是普通干电池. 就体积和重量而言,废电池在生活垃圾中是微不足道的,但它的害处却非常大,电池中含有汞、镉、铅等重金属物质.汞具有强烈的毒性,铅能造成神经紊乱、肾炎等;镉主要造成肾损伤以及骨疾--骨质疏松、软骨症及骨折.若把废电池混入生活垃圾中一起填埋,久而久之,渗出的重金属可能污染地下水和土壤.日本的水俣病就是化工企业几十年向一条河流排放大量含汞废水,下游水系中汞逐渐累积造成的.正因为如此,发达国家比较早地开始研发无汞工艺和无汞产品.从用汞大户开始,逐步削减汞的消耗量.目前,发达国家淘汰了汞法烧碱、汞法醋酸、汞法聚氯乙烯等耗汞工艺,汞的消耗量已经很低. 展开更多

The objective of this study is to investigate the existence of a relationship between executive remuneration and financial performance in 28 Brazilian companies from the industrial sector. These companies have been selected among those companies elected as "The Best Companies to Work for in Brazil". In order to operationalize the remuneration variable, the authors use the monthly salary, the variable salary and three indexes--of benefits, career and professional development--which have been created especially for this survey. To measure financial performance, the authors use three accounting measures: sales growth, return on equity (ROE) and return on sales (ROS). The results point the existence of a relationship between executive remuneration and financial performance. 展开更多
